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 Series configuration guide.

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
