HPE Smart Array P812 Controller - Replacing
Cache Module
CAUTION: To prevent damage to electrical components, properly ground the
server beforebeginning any installation, removal, or replacement procedure.
Improper grounding cancause electrostatic discharge.
1. Close all applications, and then power down the server. This method flushes all
data from the cachemodule.
2. Observe the FBWC module LEDs:
• If the green LED is off and the amber LED is on, the controller is
transferring data from DDRmemory to flash memory. Wait for data
transfer to complete (about 60 seconds), and thenproceed with the next
step.
• If the amber LED is off, then proceed with the next step.
3. Remove the controller from the server. See the documentation that ships with
the server.
4. Open the capacitor pack clip:
a. Pull the battery clip flanges outward.
b. Rotate the clip 180 degrees so that it rests on top of the capacitor pack.
CAUTION: When connecting or disconnecting the capacitor pack
cable, the connectors onthe cache module and cable are
susceptible to damage. Avoid excessive force and usecaution to
avoid damage to these connectors.
5. Remove the capacitor pack:
. Slide the capacitor pack 2 cm away from the cache module.
a. Disconnect the capacitor pack cable from the cache module.
b. Lift the capacitor pack and clip from the controller.
6. Remove the original cache module.
