8 Safety notices Safety notices Always observe the following precautions to reduce the risk of injury and equipment damage: Computer components and disk drives are sensitive to static discharge. Take precautions to discharge any electrostatic charge from your person before and while handling components with your hands or any tools. Use an anti-static wrist-strap. The system only be installed in a clean, dry environment. The operating temperature is 10º to 35º C (50º to 95º F), with operating relative humidity at 20 to 95%, non-condensing. Do not install the system in an enclosed cabinet or other small area without ventilation. Ensure correct lifting methods are used when handling the unit. Special care should be taken when removing the unit from its packaging and positioning it into its required location. When lifting the system, two people at either end should lift slowly with their feet spread out to distribute the weight. Always keep your back straight and lift with your legs. When installing the system as a rack-mounted component, ensure that all Nexsan-supplied mounting fixtures are secure. All bolts and screws should be fully tightened. Failure to comply with this may result in the unit not being fully supported in the rack and could lead to the product falling from the rack causing personal injury or falling onto other rack components. Ensure that the rack is sufficiently stable by having wall anchors and/or stabilizing legs, and that the floor supporting the rack has sufficient strength for the overall weight loading. Only a fully-trained Service Engineer is authorized to disassemble any other part of the unit, and then only when the unit is powered off. The system has multiple power connections; as a result, you must remove all power leads to completely isolate the power and always use the IEC power cords which are supplied with the system. CAUTION: All Nexsan UNITY expander units and Nexsan E-Series storage units are hot-pluggable. However, the unit that you are adding must be powered on AFTER you connect it to the existing unit.

Table 4-1: UNITY6000 hardware components Component SAS connectors Drive bays System power Rear ports for the UNITY6000 Front panel Cooling system Description High Performance 6Gb/s SAS controllers Up to 24 hot-swap drive bays with 2.5" FASTier Read cache devices 2 redundant, hot-swappable power supply units ( AC 750W Platinum). This power redundancy feature allows you to replace a failed power module without shutting down the system. The rear of the chassis includes 4 on-board gigabit Ethernet (GigE) RJ-45 ports, with 1 port dedicated to the UNITY6000 management interface and IPMI. Each UNITY6000 controller includes two Host Bus Adapters (Fibre Channel or SAS) for connectivity to Nexsan storage, two Host Bus Adapters (Fibre Channel) for host access, as well as a 10GbE I/O module for data connectivity. The front panel has one control panel to provide you with system monitoring and control. LEDs indicate system power, network (NIC) activity, system overheat and power supply failure. Each drive carrier also has LEDs to indicate the drive status. The UNITY6000 chassis has five redundant, hot-swappable fans, located behind the drive bays. The five 60x38-mm fans and an embedded fan for each installed power supply, provide the primary airflow for the system. The system is designed for fan redundancy when configured with two power supply modules. Fan redundancy is lost if more than one fan is in a failed state. 22

Chassis inter-connect Host Bus Adapter with QSFP+ to QSFP+ (SFF-8436 to SFF-8436) external cables (also used for private0 network interface) 16. Serial port B (unused) There are several LEDs on the control panel of the UNITY6000, and on the drive carriers, to keep you constantly informed of the overall status of the system and the activity and health of specific components. Control panel LEDs The control panel located on the right side of the UNITY6000 have several LEDs. These LEDs provide you with critical information related to the corresponding node. This table describes what each LED indicates when illuminated and any corrective action you may need to take. Table 4-3: UNITY6000 Control panel LEDs LED Description Power LED: Indicates power is being supplied to the system's power supply units. This LED is illuminated when the system is operating. System status LED: Bi-color (Green/Amber) indicator that shows the current health of the server system. The system provides two locations for this feature; one is located on the Front Control Panel, the other is located on the back edge of the server board, viewable from the back of the system. Both LEDs are tied together and show the same state. Off indicates that the system is powered off. A solid green LED indicates that the system is running and is healthy. 24

33 Chapter 4: UNITY6000 hardware UNITY6000 Front panel LEDs LED Description A blinking green LED indicates the system is degraded although still functional or it indicates the system is operating in a redundant state but with an impending failure warning. Possible causes can be: Redundancy loss, such as power-supply or fan Fan warning or failure when the number of fully operational fans is more than minimum number needed to cool the system Non-critical threshold crossed Temperature, voltage, input power to power supply, output current for main power rail from power supply and Processor Thermal Control sensors Power supply predictive failure occurred while redundant power supply configuration was present. Internal memory errors Battery failure Power Unit sensor offset for configuration A blinking amber LED indicates that the system is operating in a degraded state and is likely to fail. Possible causes can be: Critical threshold crossed Voltage, temperature, input power to power supply, output current for main power rail from power supply and thermal sensors Minimum number of fans to cool the system are not present or failed Hard drive fault Power Unit Redundancy sensor indicates not enough power supplies present Memory uncorrectable errors A solid amber LED indicates that the system is halted. Possible causes can be: CPU failure Power fault Runtime memory uncorrectable error Temperature issues Fatal error in processor initialization, such as processor family or model not identical Drive Activity LED: Indicates drive activity from the on-board hard disk controllers. The server board also provides a header giving access to this LED for add-in controllers. System ID button with integrated LED: Toggles the integrated ID LED and the Blue server board ID LED on and off. The System ID LED identifies the system for maintenance when the system is installed in a rack of similar server systems. System cold reset button: When pressed, this button reboots and re-initializes the system. 25

34 Chapter 4: UNITY6000 hardware UNITY6000 Rear panel LEDs LED Description Network Activity LEDs: The Front Control Panel includes an activity LED indicator for each on-board Network Interface Controller (NIC). When a network link is detected, the LED turns on solid. The LED blinks once network activity occurs at a rate that is consistent with the amount of network activity that is occurring. Non-maskable interrupt (NMI) button: When the NMI button is pressed, it puts the server in a halt state and issues a non-maskable interrupt. This can be useful when performing diagnostics for a given issue where a memory download is necessary to help determine the cause of the problem. To prevent an inadvertent system halt, the actual NMI button is located behind the Front Control Panel faceplate where it is only accessible with the use of a small tipped tool like a pin or paper clip. Drive carrier LEDs Each drive carrier on the UNITY6000 has two LEDs, a green LED on the left to indicate activity, and an amber LED on the right to indicate status. Table 4-4: UNITY6000 Drive carrier LEDs LED Green Amber Description A steady green LED indicates the drive is powered on and there is no drive activity. A green LED blinking off indicates the drive is powered on and the drive is processing a command. A steady amber LED indicates a drive failure. A blinking amber LED indicates that a RAID rebuild is in progress. UNITY6000 Rear panel LEDs You can view the status of the connection between the two UNITY6000 units by looking at the LED color on the chassis inter-connect HBA. The chassis inter-connect HBA has two ports, and each port has two LEDs, one at the top and one at the bottom. For this release, the bottom LEDs are not enabled, so you see colors on the top LEDs only.

37 Chapter 5 Chapter UNITY 5: Vault Protection Module hardware The UNITY Vault Protection Module (UNITY VPM) provides battery backup and protection to the UNITY4000/ UNITY6000 in case of power outage. Both controllers are connected to two UNITY VPM units for power redundancy. The UNITY VPM units provide power to the UNITY appliance for five minutes so that all I/O operations saved on the FASTier write cache, since the power interruption, can be written to an internal Solid State Drive (SSD) in each controller. Under normal conditions, each UNITY VPM powers its own controller, and therefore has no need to share the power load with the other UNITY VPM. The UNITY VPM is available in two models: 5P 1550GR 208V/230V unit 5P 1500R 120V unit This section includes these topics: UNITY Vault Protection Module front view 30 UNITY Vault Protection Module rear view 30 UNITY Vault Protection Module front panel LEDs and LCD screen 31 Using the UNITY Vault Protection Module LCD menu 33 Modifying the UNITY Vault Protection Module settings 34 UNITY Vault Protection Module general specifications 38
