See Figure 72 on page 86 for an example of redundant power connections. Note: For Full height drives, up to two cables can be used. Removing the covers of the laser product could result in exposure to hazardous laser radiation. Two power cords, instead of a single power cord, of the specified power cord are provided when this feature is ordered. However, this method is more risky because you can lose data if the drive restoration or storage subsystem reconfiguration process fails. Update the firmware to the latest version if required. The location of these components is shown in Figure 84.
Each caution and danger statement is numbered for easy reference to the corresponding statements in the translated document. Vor der Installation dieses Produkts die Sicherheitshinweise lesen. This redundancy is important if a hardware component fails. Note: Make sure that you stop any background programs, services or processes that write data to the logical drives. Software and hardware compatibility and upgrades Software and firmware support code upgrades.
It is possible to save and restore system parameters. This will help safeguard your equipment from potential damage due to electrical surges when power is restored. Installing and configuring the Getting started. The two host ports in each controller are independent. Refer to the Supplies section for additional information.

RecordsWhenever you add options to your controller unit, be sure to update the information in this appendix. These solutions can suppo Summary of the content on the page No. Operating the storage subsystem 93 Statement 5 2 1 Use the following procedure to turn off the power: 1. Install the storage subsystem completely before you install the software because you cannot test the software installation until the hardware is connected. Turn on the power to each device, based on the power-on sequence in step 2 on page 92.
Use the Storage Manager client to determine if the system is in an optimal state. For more information about clustering, go to the following Web sites: www. Windows is a trademark of Microsoft Corporation. The location of these components is shown in Figure 79 on page 112. No other modifications can be made to this order.
Location of drive ports Ethernet portsThere are two Ethernet interface ports, one for each controller Controller A and Controller B. Note: The connector is keyed so that there is only one way to attach the harness to the connector. Check the Storage Manager client online Help for instructions on battery replacement procedures. Leave the In lower port on drive mini hub 4 unoccupied. Plug the power cord into a properly grounded electrical outlet. Note: For the latest information about supported servers and operating systems, refer to the interoperability matrix at the following Web site: www. To remove a hot-swap fan, slide the latch on the fan to unlock it; then pull the handle and remove the fan from the storage subsystem.
Third Edition October 2006 Copyright International Business Machines Corporation 2005, 2006. For detailed information, see Table 10 on page 49 and Table 11 on page 50. Attention: When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For details about handling static-sensitive devices, see Handling static-sensitive devices on page 105. Reverse step 1 through step 4 to reinstall the components that you removed. It is best to have drives that are located near the slots that are assigned to the same logical library to minimize accessor movement and maximize performance. Attention: To avoid damage to the fiber-optic cables, follow these guidelines: v Do not route the cable along a folding cable-management arm.
The device also might have more than one power cord. This is a 2 Gbps, shortwave adapter. Connect additional storage expansion enclosures to drive loops A and B, as shown in Figure 53 on page 69. Configuration pages are context sensitive and only require valid and necessary parameters to configure. Attention: Handle and install fiber-optic cables properly to avoid degraded performance or loss of communications with devices.
Storage expansion enclosure group 1 Loop A Loop B Storage Subsystemd43nu4041 Figure 36. Remove the screw that holds the battery access panel. Select an appropriate directory and choose a file name for the profile, then click Save. Power is turned back on to the storage subsystem after the controllers are replaced. Each component of the subsystem should be checked that it is powered-on in the proper order during this entire power-up procedure to ensure the controller will be able to optimally access all of your storage subsystems. Attention: Removing the wrong drive can cause data loss. This enables continuous library operation during import or export of data cartridges.
Replace one controller at a time. This chapter includes an inventory checklist and an overview of the storage server features, operating specifications, and components. Do not overtighten the cable straps or bend the cables to a radius smaller than 38 mm 1. Use the procedure in step 4 for the proper shutdown sequence. Getting information, help, and service.
