Maintaining Sfp28 Transceivers And Fiber-Optic Cables - Cisco UCS 6400 Series Hardware Installation Manual

Maintaining SFP28 Transceivers and Fiber-Optic Cables

Procedure
Step 1
Attach an ESD wrist strap and follow the instructions for its use.
Step 2 Press the release latch on the cable, grasp the connector near the connection point, and gently pull the connector
from the transceiver.
Step 3 Insert a dust plug into the cable end of the transceiver.
Step 4
Insert a dust plug onto the end of the cable.
Maintaining SFP28 Transceivers and Fiber-Optic Cables
SFP28, 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 and
should be kept below 0.35 dB.
Consider the following maintenance guidelines:
• Transceivers are static sensitive. To prevent ESD damage, wear an ESD wrist strap that is connected to
• Do not remove and insert a transceiver more often than is necessary. Repeated removals and installation
• Keep all optical connections covered when not in use. If they become dusty, clean before using to prevent
• Do not touch ends of connectors, ensuring that they remain free of fingerprints and other contamination.
• Clean regularly; the required frequency of cleaning depends upon the environment. In addition, clean
• Inspect routinely for dust and damage. If damage is suspected, clean and then inspect fiber ends under
