ProLiant DL580 Generation 5 Maintenance and Service Guide

Removal and replacement procedures 52
CAUTION: Before starting this procedure, read the information about protecting against
electrostatic discharge ("Preventing electrostatic discharge" on page 25).
1. Perform one of the following:
o Set up a recovery server station using an identical server model. Do not install any internal drives
or BBWC in this server. (This is the preferred option.)
o Find a server that has enough empty drive bays to accommodate all the drives from the failed
server and that meets all the other requirements for drive and array migration.
2. Power down the failed server ("Power down the server" on page 26). If any data is trapped in the
cache module, an amber LED on the module blinks every 15 seconds.
CAUTION: Do not detach the cable that connects the battery pack to the cache module.
Detaching the cable causes any unsaved data in the cache module to be lost.
3. Transfer the hard drives from the failed server to the recovery server station.
4. Remove the BBWC [cache module ("Removing the BBWC cache module" on page 50) and battery
pack ("Removing the BBWC battery pack" on page 49)] from the failed server.
5. Perform one of the following:
o Install the BBWC into an empty BBWC DIMM socket on the system board of the recovery server.
o Install the BBWC into an empty BBWC DIMM socket on any Smart Array Controller in the
recovery server.
6. Power up the recovery server. A 1759 POST message is displayed, stating that valid data was
flushed from the cache. This data is now stored on the drives in the recovery server. You can now
transfer the drives (and controller, if one was used) to another server.
Battery
If the server no longer automatically displays the correct date and time, you may need to replace the
battery that provides power to the real-time clock. Under normal use, battery life is 5 to 10 years.
WARNING: The computer contains an internal lithium manganese dioxide, a vanadium
pentoxide, or an alkaline battery pack. A risk of fire and burns exists if the battery pack is not
properly handled. To reduce the risk of personal injury:
• Do not attempt to recharge the battery.
• Do not expose the battery to temperatures higher than 60°C (140°F).
• Do not disassemble, crush, puncture, short external contacts, or dispose of in fire or water.
• Replace only with the spare designated for this product.
To remove the battery:
1. Power down the server (on page 26).
2. Extend or remove the server from the rack ("Extending the server from the rack" on page 27).
3. Remove the access panel ("Removing the access panel" on page 28).
