Note:
Before you attempt to replace the SFP transceiver:
Ensure that hosts are configured according to best practices, with multiple data paths to the array, to continue
serving data during the SFP replacement procedure.
Verify that the replacement transceiver matches the type and speed of the existing transceiver.
Procedure
1. Identify the failed SFP transceiver using one of the following methods:
In the GUI, click Hardware.
If the port is not active it will have a failed (red) or unconfigured (gray) status.
In the CLI, enter the command array_name: nic --list, and then review the link status.
2. Attach the provided ESD wrist strap to an unpainted surface of the rack or array chassis.
Important:
To avoid electrostatic damage, place array components on a grounded anti-static mat. Use an ESD wrist strap
during removal and replacement.
3. Remove the SFP transceiver.
a) To ensure proper recabling later, label the cable of the SFP to be replaced. Refer to the port mapping label on the rear
of the array.
b) Remove the cable from the SFP transceiver.
c) Pull open the retaining latch on the SFP transceiver.
d) Holding the latch, gently side the SFP transceiver out of the port.
