Removal and replacement procedures 45
CAUTION: Do not detach the cable that connects the battery pack or capacitor pack to the
cache module. Detaching the cable causes all data in the cache module to be lost.
Removing the cache module
WARNING:
To reduce the risk of personal injury, electric shock, or damage to the equipment,
remove the power cord to remove power from the server. The front panel Power On/Standby
button does not completely shut off system power. Portions of the power supply and some
internal circuitry remain active until AC power is removed.
CAUTION: The cache module connector does not use the industry-standard DDR3
mini-DIMMs. Do not use the controller with cache modules designed for other controller
models, because the controller can malfunction and you can lose data. Also, do not transfer
this cache module to an unsupported controller model, because you can lose data.
To remove the component:
1. Back up all data.
2. Close all applications.
3. Power down the server (on page 26).
4. Remove all power:
a. Disconnect each power cord from the power source.
b. Disconnect each power cord from the server.
CAUTION: In systems that use external data storage, be sure that the server is the first unit
to be powered down and the last to be powered back up. Taking this precaution ensures that
the system does not erroneously mark the drives as failed when the server is powered up.
5. Extend the server from the rack (on page 26).
6. Remove the access panel (on page 28).
7. Extend the processor memory drawer approximately 2.54 to 5.1 cm (1 to 2 inches).
8. Remove the SPI board (on page 30).
9. If the existing cache module is connected to a capacitor pack, observe the FBWC module LEDs (on
page 95):
