■ Protective cap (provided with the fiber-optic jumper cable).

■ Fiber-optic cleaning kit.

Removal

To remove an SFP optical transceiver:

1. Notify the customer that the port with the defective transceiver will be

blocked. Ensure the customer’s system administrator sets the attached device

offline.

2. Identify the defective port transceiver from:

— The illuminated amber LED adjacent to the port.

— At the EWS interface, failure information associated with the port at the

Port Properties page of the View panel.

— At the HAFM appliance, failure information associated with the port at

the Hardware View, Port List View, or Port Properties dialog box.

3. Block communication to the port (“Block and Unblock Ports” on page 176).

4. Disconnect the fiber-optic jumper cable from the port:

a. Pull the keyed LC connector free from the port’s optical transceiver.

b. Place a protective cap over the jumper cable connector.

5. The optical transceiver has a wire locking bale to secure the transceiver in the

port receptacle and to assist in removal. The locking bale rotates up or down,

depending on the transceiver manufacturer and port location (top row,

odd-numbered ports 1 through 23, or bottom row, even-numbered ports 0

through 22).

a. Disengage the locking mechanism by rotating the wire locking bale up or

down 90 degrees.
