Maintaining Sfp Transceivers And Fiber-Optic Cables; Powering Up The Switch - Cisco MDS 9148T Hardware Installation Manual

Connecting the Cisco MDS 9148T Switch
Step 2
Remove attached fibre-optic cables, if any. For more information, see the
section.
Step 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.
Step 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.
Step 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:
• SFP transceivers are static-sensitive. To prevent ESD damage, wear an ESD-preventive wrist strap that
• Do not remove and reinsert a transceiver more often than necessary. Repeated removals and insertions
• Keep all optical connections covered when not in use. If they become dusty, clean them before using in
• Do not touch the ends of connectors. This prevents fingerprints and other contamination of the connectors.
• Inspect cables before installation for dust and damage. If damage is suspected, clean the ends and check

Powering Up the Switch

This section provides instructions for powering up the switch and verifying component installation.
Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the switch.
Note Do not connect the MGMT ETH0 port to the LAN until the initial switch configuration has been performed
through the console connection. For instructions on connecting this port, see the
