4: Replacing Enclosure Components
Caution: Electrostatic discharge can damage sensitive components – Touching the tray
or its components without using a proper ground might damage the equipment. To
avoid damage, use proper antistatic protection.
1. If needed, use the storage management software to create, save, and print a new
storage array profile.
2. Did the Recovery Guru direct you to replace a failed SFP transceiver?
• Yes – Go to the next step.
• No – Run the Recovery Guru to confirm the identity of the failed component, and
then go to the next step.
3. Put on antistatic protection.
4. If applicable, turn off the audible alarm by pressing the Alarm Mute button on the
front of the drive tray.
5. Unpack the new SFP transceiver. Verify that it is the same type of transceiver you
are replacing, reference. If it is not, contact your Customer Support Organization.
6. Check the controller module Fault lights to locate the failed SFP transceiver. If a
fault is detected, the amber Fault light is on.
Important: Potential degraded performance – To prevent degraded performance, do
not twist, fold, pinch, or step on fiber-optic cables. Do not bend the fiber-optic cables
tighter than a 2-inch radius.
Caution: Potential loss of data access – To prevent loss of access to data, remove only
the SFP transceiver that has a failed status as shown in the storage management software.
7. Disconnect the fiber-optic interface cables from the SFP transceiver.
8. Based on the status of the ESM Port In Bypass and the ESM Fault lights, choose one
of the following actions:
– The ESM Port In Bypass light or the ESM Fault light is on – Reinstall the SFP
transceiver and the fiber-optic cables, and verify that the SFP transceiver and
fiber-optic cables are securely connected. When finished, go on to the next step.
– The ESM Port In Bypass light and the ESM Fault light are off – Go to step 11.
