Disconnecting Optical Ports From The Network; Maintaining Transceivers And Optical Cables - Cisco Nexus 7706 Hardware Installation Manual

Disconnecting Optical Ports from the Network

To prevent possible damage to the cable or transceiver, install the transceiver in the port before installing the
cable in the transceiver.
Step 1 Attach an ESD-preventative wrist strap and follow its instructions for use.
Step 2
Remove the dust cover from the port 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 (see
the following figure for SFP or SFP+ transceivers).

If the cable does not install easily, ensure that it is correctly oriented before continuing.
Disconnecting Optical Ports from the Network
When removing fiber-optic transceivers, you must remove the fiber-optic cables from a transceiver before
removing the transceiver from the port.

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. Attenuation (loss of light) is increased by contamination 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
