Note: Use only Cisco transceivers in the IBM SAN48C-6 switch. Each Cisco transceiver is encoded with
model information that enables the switch to verify that the transceiver meets the requirements for the
switch.
The IBM SAN48C-6Cisco MDS 9148T Switch switch supports transceivers with the following types of
latching devices:
• Mylar tab latch
• Bale-clasp latch
Installing an SFP Transceiver
About this task
To install an SFP+ transceiver, follow these steps:
Procedure
1. Attach an ESD-preventive wrist strap and follow its instructions for use.
2. Remove the dust plug from the FC port.
3. Insert the transceiver into the port.
CAUTION: The transceiver can only be inserted one way into the FC port. If the transceiver
does not install easily, ensure that it is correctly oriented and the tab or clasp are in the correct
position before continuing.
4. Insert or leave the dust plug in the cable-end of the transceiver if a cable is not being installed in the
transceiver.
Removing an SFP Transceiver
About this task
To remove an SFP+ transceiver, follow these steps:
Procedure
1. Attach an ESD-preventive wrist strap and follow its instructions for use.
2. Remove attached fibre-optic cables, if any. For more information, see the Removing a Cable from an
3. Remove the transceiver from the port:
• If the transceiver has a Mylar tab latch, gently pull the tab straight out (do not twist), and then pull
the transceiver out of the port.
• If the transceiver has a bale-clasp latch, open the clasp by pressing it downwards, and then pull the
transceiver out of the port.
4. Insert a dust cover into the cable-end of the transceiver and place the transceiver on an antistatic mat
or into a static shielding bag.
5. Protect the FC port by inserting a clean dust plug if another transceiver is not being installed.
Maintaining SFP Transceivers and Fiber-Optic Cables
SFP transceivers and fiber optic cables must be kept clean and dust-free to maintain high signal accuracy
and prevent damage to the connectors. Attenuation (loss of light) is increased by contamination.
Therefore, attenuation should be kept below 0.35 dB.
Follow these maintenance guidelines:
