17 Chapter 1 Overview1- This chapter presents an overview of the design and service features of the Distributed Network Control Platform (DNCP) Series 400 and Series 400-CO systems, also simply called the Series 400 and Series 400-CO systems. CO indicates Central Office facilities and equipment, and a -48Vdc power source. DNCP Series 400 systems (without CO appended) require a 200/208/240Vac power source. This chapter covers the following major topics. Systems Overview System Cabinet System Components Peripherals Systems Overview DNCP Series 400 and 400-CO systems combine the Hewlett-Packard PA-RISC 8500 microprocessor, and HP-UX operating system with Stratus continuously available hardware designed specifically for central office (CO) environments to provide operating redundancy, and five 9s reliability (99.999% uptime). DNCP Series 400-CO systems are powered with two duplex -48Vdc nominal electrical inputs. Battery backup is not required because the systems receive continuous power from the central office battery plant, a source that is external to the system. DNCP Series 400 systems are powered with duplex 200/208/240Vac nominal electrical inputs. Battery backup may be used, as required. A peripheral component interconnect (PCI) bus in the Series 400 and 400-CO systems enables PCI Small Computer System Interface (SCSI) peripheral I/O cards, and communications adapter cards to be used. Figure 1-1 shows a typical DNCP Series 400-CO system cabinet with the front and rear doors open, and the perforated top cover removed to provide an opening for the system cables. Figure 1-2 shows a typical DNCP Series 400 system cabinet with the front and rear doors open, and an opening in the bottom of the cabinet through which cables can be routed. Overview 1-1

20 Systems Overview Fault Tolerance DNCP Series 400 and 400-CO systems incorporate the following fault-tolerant features: Serviceability Few singular points-of-failure Fully self-checking logic on DNCP components Status indicator lights for all major system modules Unique PCI bus fault isolation and recovery On-line system servicing (hot-pluggable) On-line upgrades Disk mirroring (through the operating system) Multiple, variable speed cooling fans that automatically adjust to environmental conditions No degradation in system performance if a part fails Many of the Series 400 and 400-CO systems essential components are customer replaceable units (CRUs). As a result, you can often maintain the system without requiring help from customer support personnel. CRUs are of manageable weights, and most of them can be replaced without using tools. Appendix A contains an Illustrated Parts Breakdown (IPB) of the system CRUs. Most CRUs are hot-pluggable and can be hot-swapped, meaning that you can remove them from or add them to the system without interrupting system operation, or entering system commands. DNCP Series 400-CO systems include status lights to indicate the operational status of all CRUs. Chapter 2 describes the status lights in detail. When a part fails, the system automatically performs the following activities: Displays an error message on the system console Writes the part failure information to the system error log Lights a red status light on the failed unit Lights the cabinet s front and rear CABINET FAULT lights Sends a part failure message to the Stratus Customer Assistance Center (CAC) over the Remote Service Network (RSN), if your system is connected to the CAC. When your system sends the CAC a part failure message, a CAC engineer contacts you to confirm the failure. Then, if needed, the CAC ships you a replacement part. Figure 1-3 illustrates the part failure notification process. 1-4 DNCP Series 400 and 400-CO: Operation and Maintenance Guide (MAN0056)

26 System Cabinet System Cabinet The cabinet houses the base system components in a tower arrangement. Base system components are those required to makeup a functional system. The V105 terminal, CD-ROM drives, tape drives, printers, modems and remote system consoles are not included among the base system components. The cabinet supports Zone 4 seismic resilience standards for a central office (CO) environment. Front and rear cabinet doors provide access to the system, subsystems and components. The doors louvered panels provide ventilation for cooling. The cabinet doors open from the center. To open the cabinet, press the top of the cabinet handle, lift the handle, and turn it counterclockwise. Open the front doors to access the power switches, power supplies, ACUs, disk power supplies and disk drives, logic suitcases, and the air filters (Series 400-CO only). Open the rear doors to access the power cords, Disk Fan Modules 0-2, SE/SE I/O Module, SES Unit, SE/LVD Terminator Module, PCI Card Cages, I/O card cables, and the connectors for the system serial ports. Note that it is not necessary to have the cabinet doors closed to operate the system. Amber CABINET FAULT lights are located on the top-front and top-rear of the cabinet frame, and are visible whether the doors are open or closed. The top of the cabinet contains an opening for the cables when they are routed down through the top. The system base is also open and accommodates system cabling routed under a raised floor. When cables are routed through the base, the opening in the top of the cabinet is covered with a perforated cover. These top and base openings also play a significant role in cooling the system. Series 400 and 400-CO System Component Numbering The logical numbering of system components power supplies, logic suitcases, and so on proceeds from 0 to 1, moving right-to-left, beginning from the front of the system. For instance, the Main Power Supply on the right-front of the cabinet is Main Power Supply 0, and the one on the left is Main Power Supply 1, the same is true for the logic suitcases, and so on with the other components. However, there are a few exceptions to this numbering pattern. In the Series 400 system: The AC to 48Vdc Front End or Power Subsystem includes two 3U type power trays. These trays are arranged one over the other, not side by side. Tray 1 is the lower tray, and Tray 2 is the upper tray. Disk Trays 0 and 1 are arranged one over the other, not side by side. The upper disk tray is Tray 0, and the lower disk tray is Tray 1. PCI Card Cage 3 is on the left, and PCI Card Cage 2 is on the right, looking from the rear of the cabinet. The card cages are also called card bays DNCP Series 400 and 400-CO: Operation and Maintenance Guide (MAN0056)

27 System Cabinet The six disk fan modules in the rear of the system are arranged side by side in two rows (three fans per row), and are numbered as follows (viewing from the rear): Cabinet Labeling The Series 400 and 400-CO system cabinets come with a variety of labels, which provide the following functions: Identify many system components and their logical part numbers Summarize the meaning of the various states of the status lights Summarize how each labeled part functions; for example, the latches on the PCI card cage door Identify the on/off positions of power switches Identify PCI card slot numbers Provide other reminders and cautions to system users Note that the illustrations found in this guide generally omit these labels; however, they are placed in locations where they are readily evident. Cabinet Front Doors The two cabinet front doors provide access to all base system CRUs except for the PCI cards, fan modules, and system power cords. Figure 1-6 shows the front of the Series 400-CO system cabinet with the front doors open. A front view of the Series 400 system cabinet with the front doors open is provided in Figure 1-7. A card labeled STATUS LIGHTS CRU LEDS is attached to the backplane access cover on the front of the cabinet. The card summarizes the meaning of the various states of the status lights for the power supplies, ACUs, disk drives, and logic suitcases. NOTE The backplane access cover should only be removed by properly trained service personnel. In the remaining figures in this chapter, many of the small circles represent status lights. These status lights are not called out in the figures in this chapter, but are identified in many of the figures in Chapter 2. Overview 1-11

32 System Cabinet Air Filters The Series 400-CO system has optional air filters and filter covers for the: ACU and PCI power supplies Disk trays Logic suitcases These filters and filter covers are initially supplied as an optional Air Filters Installation Kit (Part No. AK ), and replacement filters are supplied as a Replacement Filters Kit (Part No. AK ). Except for the logic suitcase filter, these optional filters are housed in hinged, metal filter covers that are secured to the cabinet with thumbscrews. The filter for the logic suitcases is contained in a labeled air filter enclosure that is inserted under the logic suitcases. Figure 1-10 shows the filter locations. All the filters are accessible from the front of the cabinet. Filters must be changed regularly as part of routine maintenance. Replacement frequency depends upon your particular system environment. CAUTION Make sure the filter cage covers are closed before you close the cabinet front doors. Serial Ports There are four serial input/output (I/O) ports provided on the bottom left-rear of the cabinet (see Figure 1-11) that are basically used for data I/O.

The cooling system cools internal cabinet components by drawing air in through the bottom front of the cabinet and exhausting it out the top-rear. Two fans in the top of each logic suitcase draw air through the bottom of the cabinet to cool the boards inside the suitcase. The air that flows through the top of the logic suitcases, is drawn up to cool the PCI cards, and is then exhausted through vents in the rear of the card cage. There are three fan modules under each disk tray in the rear of the cabinet that draw air through the disk drives from the front, and exhaust it upwards out the rear of the cabinet. Fans located in the front of each ACU and PCI power supply draw air through the power supply units and exhaust it through the rear of the units DNCP Series 400 and 400-CO: Operation and Maintenance Guide (MAN0056)

35 System Cabinet CAUTION Obstructing air flow can overheat the system and cause parts to fail. The system requires 2 ft. (0.6m) of clearance at the front and rear of the cabinet, and a minimum of 1.5 ft. (0.5m) of unobstructed area on the top of the cabinet above the cable trough. If you remove the caster plates and mount the system directly to the floor, you must allow for airflow through the bottom of the cabinet by providing openings in the raised floor beneath the cabinet and, if applicable, removing the side plates at the bottom of the cabinet (See DNCP Series 400/400-CO: Attaching and Removing the Caster Plates (MAN0051). Table 1-1 shows the total area of openings in the raised floor required to allow sufficient airflow. Openings must be evenly distributed between the front and rear lower frame rails of the cabinet. Table 1-1. Floor Airflow Openings Required for Floor-Mounted Cabinets Side Plates Removed and openings unblocked Attached or openings blocked Required Area of Openings Beneath Cabinet 55 sq. in (355 sq. cm) 155 sq. in (1000 sq. cm) The ambient temperature at the air inlet of the system must be between 41 F and 104 F (5 C and 40 C), and for optimum operation, between 68 F and 86 F (20 C and 30 C). Each ACU power supply (in Series 400-CO systems) contains a fan to draw air through the unit. Each PCI power supply (in Series 400-CO system) and PCI/ACU power supply (in the Series 400 system) has one fixed speed fan, so there is no shift to high speed operation when one of the PCI power supplies fails. Each logic suitcase has two fans. If one fan in a suitcase fails, the suitcase takes itself out of service, and the two fans in the other suitcase increase their rotational speed to compensate. The suitcase with the failed fan is then replaced. Each of the disk tray fan modules (located in the rear) contains three variable speed fans to cool the disk trays (see Figure 1-8). When the temperature increases above the normal operating temperature the speed of the fans also increases to maintain adequate cooling. Overview 1-19

36 System Cabinet If one of the disk tray fans fails, the other fans on that tray shift to a higher speed to maintain an adequate cooling level. When the failed fan is replaced, the other fans gradually return to normal operation as the operating temperature returns to normal. cp0167 Figure System Air Flow and Cooling 1-20 DNCP Series 400 and 400-CO: Operation and Maintenance Guide (MAN0056)

37 System Components System Components The cabinet contains the base system components of a Series 400 or Series 400-CO system. These components are summarized below, and described in succeeding subparagraphs. Series 400-CO System ACU and PCI Power Supplies Series 400 System PCI Power Supplies and ACU Boards Alarm Control Units Disk Drives and Disk Power Supplies Logic Suitcases PCI Subsystem Series 400-CO System ACU and PCI Power Supplies In the Series 400-CO system, four power supplies are located in the upper half of the cabinet, and provide power to the ACUs and the PCI subsystems (see Figure 1-13). The upper power supply pair powers the ACUs, and the lower pair of power supplies power the PCI card cages. The ACU power supplies are duplexed to provide fault tolerant power. If one power supply fails, the other continues to operate, and the ACUs continue operating without interruption. CAUTION Never remove a power supply without first turning off the appropriate ACU or PCI subsystem power switch. Each PCI power supply provides simplex power to one PCI card cage. Therefore, when a PCI power supply fails, only one PCI subsystem loses power. This design enables you to shut down the PCI cards in one PCI card cage to perform a card upgrade or replacement, while the PCI cards in the other PCI card cage continue to operate. When installed, an optional hinged cover that holds air filters covers the face of the ACU and PCI power supplies in a Series 400-CO system. The cover is shown in Figure Overview 1-21

38 System Components Disk Power Supplies PCI Power Supplies cp0076 Figure Series 400-CO System ACUs, PCI, and Disk Power Supplies Series 400 System PCI Power Supplies and ACU Boards In the Series 400 system, the AC to 48Vdc Power Front End or Subsystem fits in the same 6U area as the 48Vdc Power Subsystem used with the Series 400-CO system. The AC to 48Vdc Power Subsystem is comprised of two trays. The lower tray is Tray 1 and the upper tray is Tray 2. The PCI/ACU Power Supplies and ACU Boards are contained in the upper Tray 2 (see Figure 1-14) DNCP Series 400 and 400-CO: Operation and Maintenance Guide (MAN0056)

39 System Components Front of System PCI/ACU Power Supplies Alarm Control Units Disk Power Supplies cp0355 Figure Series 400 System ACUs, PCI and Disk Power Supplies Alarm Control Units Two alarm control units (ACUs) monitor the fans, the state of certain status indicator lights, and the status of the peripheral devices. The ACUs also provide relay contacts for connecting remote alarm indicators. Viewing the cabinet from the front, the ACUs are located in the upper half of the cabinet to the right of the power supplies in the Series 400-CO system, and below the PCI/ACU Power supplies in the Series 400 system. The ACUs are redundant in that they monitor the status of the same components, and an alarm condition occurs if one ACU s system log differs from the system log of the other ACU. ACU1 is the master ACU. If ACU1 is absent or defective, ACU0 takes over ACU1 s functions. If both ACUs fail at the same time, the system will continue to operate, but will not continue to gather fault information from the field replaceable units (FRUs) and customer replaceable units (CRUs) that the ACUs monitor. Overview 1-23

40 System Components Disk Drives and Disk Power Supplies DNCP Series 400-CO systems support two different D84x SCSI disk drive models and storage capacities, which are listed below. A D GB Disk Drive will also be offered in Q2 of D841: 9 GB D842: 18 GB The system houses up to 14 physical disk drives (seven logical drives with mirroring). Current maximum storage capacity is 252 GB (126 GB mirrored capacity). Each D84x Series disk drive provides the same overall functionality, except for the differences in storage capacity. The D84x Series Disk Drives operate at 10,000 rpm, and contain an embedded, single-ended (SE) SCSI interface that supports synchronous data transfer rates up to 20 megabytes per second (MBps). The disk drives are hot-pluggable, and are housed in two 9-slot disk trays in the Series 400 and Series 400-CO system cabinets (Figure 1-15). Each disk tray receives input power from both of its two disk power supply modules, providing a redundant power source to both disk trays. The disk drives in one disk tray mirror (exactly duplicate) the disk drives in the other disk tray. The disks are installed in the following pattern, which corresponds to the slotloc columns in the system output With the Series 400-CO system, an optional hinged cover containing an air filter can be installed to cover the face of the disk drive enclosure. The cover is shown in Figure This option is not offered with the Series 400 system. The variable-speed disk drive fans (located in the back of the cabinet under the disk trays) provide cooling for the disk drives, and are customer-replaceable units (CRUs).

43 System Components Logic Suitcases Two logic suitcases (called suitcases because of their appearance) contain the system s central processor unit (CPU) logic functions, and main memory. The two logic suitcases are normally partnered and operated in duplex mode, except when one fails or is taken off-line, the remaining suitcase then operates in simplex mode. Figure 1-17 shows the location of the logic suitcases. Each logic suitcase contains two (logical uni) or four (logical twin) Hewlett-Packard PA-RISC 8500 CPU(s), memory modules, a power supply and a console controller, which is the system s central collection point for maintenance and diagnostic information. NOTE You cannot replace the individual components of a logic suitcase. If a component fails, you must replace the entire logic suitcase. Each logic suitcase contains its own power supply, which takes a dc input voltage and supplies logic-level operating voltages to the internal components. Each logic suitcase is cooled by two internal fans. If one of the fans fails, the logic suitcase takes itself out of service, and the two fans in the other suitcase shift to high speed. The fans draw air in through the bottom-front of the cabinet and discharge the heated air out the top of the logic suitcase. Three status lights on the front of each logic suitcase, indicate its operating status. If one of the components in a suitcase fails, the suitcase takes itself out of service, and the system continues to operate using the other logic suitcase. The CPU/memory motherboard in the logic suitcase connects to four system serial ports (three RS-232 ports and one RS-485 port), all located on the rear of the cabinet. The RS-232 serial ports are for the Remote Service Network (RSN) modem, system console, and remote console. The RS-485 port, labeled CABINET BUS, is reserved for internal communications with the Alarm Control Units (ACUs). You can use the serial ports in either of the two wiring schemes summarized below Port 4, J307 Port 3, Console Port 2, Remote Console Port 1, RSN Cabinet Bus Primary Console Secondary Console Cabinet Bus Primary Console Secondary Console RSN Tertiary Console Overview 1-27

45 System Components PCI Subsystem The PCI subsystem is made up of the following components, and is described in the succeeding paragraphs. PCI Bus PCI Card Cages PCI Bridge Cards PCMCIA Flash Cards PCI Cards Figure 1-18 shows the location of the PCI subsystem, card cages, and PCI cards. PCI Bus The PCI bus is an industry standard data communications bus. This fully synchronous, high bandwidth, 32-bit, low latency bus operates at 24 MHz, and uses a multiplexed Address/Data Bus (ADB) to transmit data. The PCI backplane provides signal, power, and ground connections between the logic suitcases and the PCI card cages. PCI Card Cages Each DNCP Series 400-CO System has two partnered 8-slot PCI card cages, for a total of 16 slots per system. Each card cage reserves one slot for a PCI bridge card, with seven slots available for other PCI cards. Each PCI card cage is powered by its own simplex PCI power supply. If the power supply to one card cage fails, or the card cage s door is opened, its cards go offline. However, the PCI power supply and PCI cards in the other card cage remain on-line, and continue to function without interruption. Once you replace the defective power supply or close the open card cage door, the PCI cards in the opened card cage go back on-line within a few seconds. CAUTION Opening the card cage door removes power to that side of the system. If power is removed from the other side of the system at the same time, the system will crash. As a precaution against removing power from both sides of the system at the same time, the PCI card cage doors are interlocked. You should only be able to open one card cage door at a time. A label on the card cage door shows how the knob position locks or unlocks the card cages. Overview 1-29

46 System Components Rear PCI Card Cage 2 PCI Card Cage 3 cp0080 Figure Location of the PCI Subsystem As further insurance against accidentally crashing the system, observe the following cautions. CAUTIONS 1. If a PCI power supply is broken (red light is on) or missing, do not open the PCI card cage on the opposite side of the system; the system will crash. 2. Never open the PCI card cage door on the same side as a PCI power supply that has a yellow and green indicator lit or it will crash the system. 3. Always allow time for a card cage to come back on-line before you open the door to the other partnered card cage. PCI Bridge Cards The PCI bridge cards provide the interface between the logic suitcases and the PCI cards. The PCI bridge cards isolate the PCI cards in the card cage from the logic suitcases so a failure in one card cage does not affect the operation of the other card cage DNCP Series 400 and 400-CO: Operation and Maintenance Guide (MAN0056)
