Replacing a 2-Gb small form factor pluggable (SFP) transceiver

The transceiver is hot-pluggable, so it is not necessary to power down the system to replace it.

Before you begin

WARNING!
To reduce the risk of injury from laser radiation or damage to the equipment, observe the following
precautions:
• Do not open any panels, operate controls, make adjustments, or perform procedures to a laser
device other than those specified herein.
• Do not stare into laser beam when panels are open.
CAUTION:
• Before removing a component or blanking panel from an operational device, make sure that you
have the replacement part available. Removing a component or blank impacts the airflow and
cooling ability of the device. To avoid possible overheating, insert the new or replacement component
within one or two minutes. If the internal temperature exceeds acceptable limits, the device may
overheat and automatically shut down or restart.
• Parts can be damaged by electrostatic discharge. Use proper anti-static protection.

Verifying component failure

Before replacing the SFP:
• Verify that the Fibre Channel I/O module status LED is not illuminated or is blinking amber.
• Check the array controller LCD display panel for error messages.

3.
Remove the transceiver, either by pulling on the plastic tab or by swiveling the small wire handle on
the SFP, depending on the SFP model.
4.
Attach the protective cover on the cable and insert the dust plug cover in the failed SFP.

Installing the component

CAUTION:
To reduce the risk of damage to the equipment, do not use excessive force when inserting
the SFP.
