4 1 Product Information Introduction The cabinets contain several hardware components that can be replaced by Teradata customers without the help of Teradata service personnel. Replaceable components include: Disk array storage drives Disk array power supplies Processing node power supplies Cabinet Builds for 2750 Cabinet Build Conventions The placement of the hardware components in a cabinet follows these general cabinet build conventions: Each chassis has a standard position in the cabinet, and is numbered from the bottom up. Chassis that are managed over the server management network have assigned chassis ID numbers. The chassis ID number identifies the chassis by position/type in the management interface. Unmanaged chassis are numbered by position for cabling purposes only. The numbers do not appear in the management interface as identification of the chassis. All chassis except the top Ethernet switches are loaded from the front of the cabinet, and accessible from both front and rear of the cabinet. The top Ethernet switches are loaded and accessible only from the rear of the cabinet. Additional build conventions for 2750 processing/storage cabinets: In a base cabinet with a 4-node clique, all four nodes in the clique are not adjacent to each other - the top node of the clique (chassis 15) is separated from the bottom three nodes (chassis 8, 9, 10) by the BYNET switches, VMS, and KVM chassis. Channel servers, Extended Channel Solution (ECS) servers, Network Connectivity Servers (NCSs), SAS HPA worker nodes, Teradata Managed Servers (TMSs), and Teradata Managed Storage Servers (TMSSs) must be placed in base cabinets or Platform Framework Cabinets. The base cabinet supports up to eight of these chassis. The Quantum i80 tape libraries used for backup and restore (BAR) must be placed only in base cabinets. The base cabinet supports one tape library with an optional pair of key management servers, or up to two tape libraries without key management. Only one TMS BAR is permitted for these Scalar i80 BAR tape library configuration options. The Data Domain 4200 and ES30 expansion shelves used for backup and restore (BAR) must be placed only in base cabinets. The base cabinet supports one DD4200 with up to three ES30 expansion shelves. Only one TMS BAR is permitted for the Data Domain 4200 and ES30 options. 4

5 1: Product Information This document gives basic chassis location guidelines. For detailed system design considerations, including guidelines for future system capacity upgrades and multiple Data Domain systems, see the Ordering & Configuration Information document for Model DD4200. Test/development systems must be placed only in base cabinets. Each Teradata production system, consisting of one or more production cabinets, supports up to two test/development systems. 5

23 1: Product Information Servicing Cautions and Warnings The following cautions and warnings apply when servicing components in the rack-mount system. Only the hardware components described in this document should be serviced by non-teradata personnel; all other hardware components in the Teradata system must be serviced by a Teradata Customer Support Representative (CSR). Problems resulting from failure to strictly follow Teradata-provided instructions and documentation, use of non- Teradata-provided parts, accessing or initiating replacement procedures not covered in this document will void your warranty or service contract. Data loss may occur from failure to strictly follow Teradata-provided instructions and documentation, use of non- Teradata-provided parts, or accessing or initiating other replacement procedures. WARNING This equipment has high leakage current. Reliable earth grounding of this equipment must be maintained. Grounding is provided by the power plug. The ground wire in each power cord is connected to a ground terminal in the power plug. The customer must ensure that the receptacle is properly grounded. Failure to observe these precautions can kill or injure personnel or damage the system. General Cabinet Servicing Closely monitor the system through SMClient for temperature warnings during a service session with the front cabinet door open. In the event of a warning, close the front door immediately. Failure to do so will result in nodes shutdown, data corruption, hardware damage, or other problems. Store all components in static-protective packaging. After removing a board or adapter from its protective wrapper or from a chassis, place it component-side up on a grounded, static-free surface, or on a conductive foam pad. Wear an anti-static wrist strap attached to an unpainted metal surface on the rack or chassis when handling parts. The AC boxes in a cabinet are not intended to provide power to equipment that is not mounted in the cabinet. Plugging equipment not authorized for the cabinet into the AC box may result in an overvoltage condition or damage the external equipment. The cabinet contains more than one AC power cord. To remove all power from the cabinet, all AC power cords must be disconnected from the site power source. 23

24 1: Product Information Storage Drives Teradata is not liable for customer data left on returned storage drives. If you accidentally remove an active drive, wait at least 30 seconds, then reinstall the drive. Contact your service representative for further instructions. The drive tray is designed to run with all hardware components in place. Do not remove a hardware component until you have the replacement component available. To avoid loss of data access, never remove a drive that has not failed. Only remove a drive that has both the Service Action Required and Service Action Allowed lights on. To avoid damage to drives, never bump a drive against another surface that might damage the drive mechanism or connectors. To prevent damage when removing or installing a drive, always place your hand under the drive to support its weight as you remove or install the drive. Always handle boards and adapters carefully and only by their edges. Disk Array and Node Power Supplies CAUTION Do not open the power supply modules. There is a risk of electrical shock and burns from high voltage and rapid overheating. 24

25 2 Before Replacing a Component Hardware Failure Notifications When your system was delivered, your Teradata Customer Service Representative (CSR) configured Server Management Web Services (SMWeb) to provide alerts through Server Management Client when there are storage drive or power supply failures. When a disk array storage drive, disk array power supply, or node power supply fails, Server Management Client logs the hardware failure in its Alert Viewer window. The Alert Viewer window must be monitored for these failures. When a disk array, disk array power supply, or node power supply fails, Server Management Client logs the hardware failure in its Summary Alerts tab. The Summary Alerts tab must be monitored for these failures. For more information about SMWeb and Server Management Client, see the Teradata Server Management Web Services User Guide, B Initiating an Incident 1. If your service agreement does not include Automatic Incident Creation, log on to and initiate an incident. Obtaining a Replacement Part If your company's contract with Teradata includes on-site storage of spares, then disk drives are stored on site. Power supply replacements must be ordered through 1. If the replacement part is stored on site, obtain it from your hardware spares. 2. If the replacement part is not stored on site: a. Log on to and initiate an incident. Teradata orders a replacement hardware component and sends it to your site in accordance with your service contract. Additionally, Teradata sends the shipping information and return label to the address provided in Notifications. Save Teradata s for future reference. b. When you receive the replacement part, note the identification tag of the new component and compare it to the identification tag of the failed component. If the types do not match, do not continue with the replacement procedure. If any problems are encountered, notify Teradata Customer Support. Use a contact method that is in accordance with your service contract. If your system is not set up with Automatic Incident Creation (AIC), log on to and initiate or update an incident. If your system is set up with AIC, close the maintenance window and add a comment. 25

26 Replacing a Storage Drive Replacing a storage drive may require a restart of the Teradata Database. If there is a firmware mismatch between the new storage drive and the currently installed drives, Teradata highly recommends that the firmware be updated to the same level as the currently installed drives. Updating the firmware requires a restart of the database. Before starting this procedure, the customer must communicate to the CSR that replacing a storage drive may require a database restart and, if necessary, coordinate with the CSR to find a convenient time for performing the firmware update. Observe all servicing cautions and warnings. Preparing for the Procedure Data loss and/or warranty violation may occur if this procedure is not strictly followed. Accessing or initiating other replacement procedures may cause data loss and loss of warranty coverage.
