Removing The Cache Module - HPE ProLiant DL580 Gen9 Maintenance And Service Manual

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. Pressing the Power On/Standby
button does not shut off system power completely. 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:
Back up all data.
1.
Close all applications.
2.
Power down the server (on page 26).
3.
Remove all power:
4.
Disconnect each power cord from the power source.
a.
Disconnect each power cord from the server.
b.
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.
Extend the server from the rack (on page 26).
5.
Remove the access panel (on page 28).
6.
Extend the processor memory drawer approximately 2.54 to 5.1 cm (1 to 2 inches).
7.
Remove the SPI board (on page 30).
8.
If the existing cache module is connected to a capacitor pack, observe the FBWC module LEDs (on
9.
page 95):
If the amber LED is flashing, data is trapped in the cache. Restore system power, and then
o
restart this procedure from step 1.
If the amber LED is not illuminated, remove the controller from the server, and then continue with
o
the next step.
