IMPORTANT:
See the storage system administration guide for additional
information.
Error codes
The seven-segment display indicates Power On Self Test (POST) and
system status information. During normal operation the display will read
“on.”
Error codes consist of four characters, but only two characters are
displayed at a time. Pressing the up or down arrow button on the
seven-segment display shows the remaining characters.
The first character represents the domain code:
• C—Configuration error
• F—Firmware error
• H—Hardware error
The second character indicates the controller signalling the error:
• 1—Controller 1
• 2—Controller 2
The third and fourth characters indicate the specific error on the controller:
(Displayed by pressing the up or down arrow button on the
seven-segment display.)

• Cache module retention clip
• Package of rubber spacers (2)
Preparation
1. Ensure that a known, good system backup is available.
2. Schedule a maintenance window.
3. From the servers, prepare to stop all access to the enclosure.
(Optional in dual controller configurations.)
Step 1: Removing the controller
CAUTION:
Do not remove a controller from the chassis while the controller
status LED is green. Removing an active controller (green LED)
may result in data loss.
1. From the servers, stop all access to the enclosure. (Optional in dual
controller configurations.)
2. Label each cable connected to the controller with its port number.
This ensures proper re-connection after completing the cache module
replacement.
3. Remove the cables from the controller.
4. Remove the controller from the chassis:
a. Squeeze the controller thumb latch (1) and rotate the latch
handle down (2).
b. Pull the controller straight out of the chassis (3).
IMPORTANT:
As you pull the controller out of the enclosure, keep
it level until it is completely out of the chassis. If the
controller is tilted, it is possible to catch a
component on the chassis edge and damage the
controller.
