Installing Sfp+ And Sfp Optical Cables; Maintaining Transceivers And Optical Cables - Cisco Nexus 3550-T Hardware Installation Manual

Connecting the Switch to the Network
• If the transceiver has a Mylar tab latch, position the transceiver with the tab on the bottom, and then gently insert
the transceiver into the port until it clicks into place.
• If the transceiver has a bale clasp latch, position the transceiver with the clasp on the bottom, close the clasp by
pushing it up over the transceiver, and then gently insert the transceiver into the port until it clicks into place.
Caution If the transceiver does not install easily, ensure that it is correctly positioned and the tab or clasp are in
the correct position before continuing.

Installing SFP+ and SFP Optical Cables

Note To prevent damage to an optical cable and transceiver, disconnect cables before installing or removing
transceivers.
Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.
Step 2
Remove the dust cover from the connector on the cable.
Step 3 Remove the dust cover from the cable end of the transceiver.
Step 4
Align the cable connector with the transceiver and insert the connector into the transceiver until it clicks into place.
Caution If the cable does not install easily, ensure that it is correctly positioned before continuing.
Note If you cannot install the cable into the transceiver, insert or leave the dust plug in the cable end of the transceiver.
For instructions on verifying connectivity, see the appropriate Cisco Nexus 3550-T Triton Configuration Guide.

Maintaining Transceivers and Optical Cables

Transceivers and fiber-optic cables must be kept clean and dust free to maintain high signal accuracy and
prevent damage to the connectors. Contamination increases attenuation (loss of light) and should be below
0.35 dB.
Consider the following maintenance guidelines:
• Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is
• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions
• Keep all optical connections covered when not in use. Clean them before using to prevent dust from
