CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or
removing cable. The safety cap keeps the port clean and prevents accidental exposure
to laser light.
6. Arrange the cable in the cable management system to prevent the cable from dislodging or
developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to
the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system.
Placing fasteners on the loop helps to maintain its shape.
CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening point.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause problems that
are difficult to diagnose.
7. Verify that the status LEDs on the indicate that the QSFP28 is functioning correctly.
Remove a Transceiver
Before you remove a transceiver from a device, ensure that you have taken the necessary precautions
for the safe handling of lasers (see
Ensure that you have the following parts and tools available:
• An antistatic bag or an antistatic mat
• Rubber safety caps to cover the transceiver and fiber-optic cable connector
• A dust cover to cover the port or a replacement transceiver
NOTE: After you remove a transceiver, or when you change the media-type configuration, wait
for 6 seconds for the interface to display the operational commands.
Figure 48 on page 119
shows how to remove an SFP+ or QSFP+ transceiver.
