Removing an expander module
Prerequisites
1. Follow the safety guidelines listed in
on page 14.
2.
CAUTION:
The sled is not designed to function on a single expander module. It is mandatory that both the modules be
present in the sled for optimum performance.
CAUTION:
Do not remove both expander modules when sled is powered on. Removing both the expander at once causes
critical failure of the enclosure which can only be recovered after a power cycle of the storage sled.
CAUTION:
Sled should not be open for more than three minutes while the enclosure is on.
CAUTION:
Some of the components on the back of the expander may be hot to touch.
NOTE:
System health indicator blinks amber to indicate loss of redundancy when an expander module has failed or has
been removed.
NOTE:
If you remove an expander that is mapped to a compute sled, the ongoing I/O operations are interrupted.
Steps
1. Press the release button to unlock the expander module lever.
2. Lift the expander module lever until the expander module disengages from the module slot.
3. Remove the expander module out of the system.
