WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
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.
CAUTION: To prevent damage to electrical components, take the appropriate anti-static
precautions before beginning any installation, removal, or replacement procedure. Improper
grounding can cause electrostatic discharge.
To remove the component:
1. Power down the server (on page 27).
2. Remove all power:
a. Disconnect each power cord from the power source.
b. Disconnect each power cord from the server.
3. Do one of the following:
o Extend the server from the rack (on page 27).
o Remove the server from the rack (on page 30).
4. Remove the access panel ("Access panel" on page 35).
5. If the cache module is installed on a storage controller board that is installed in a PCI riser cage,
remove the riser cage ("Remove the PCI riser cages" on page 31).
6. If necessary for easier access to the cache module connector and/or removal of an air scoop,
remove the storage controller from the PCI riser cage or from the system board ("Expansion board"
on page 54).
7. If the cache module is covered by an air scoop, remove the air scoop.
