To install a transceiver:
CAUTION: To prevent electrostatic discharge (ESD) damage to the transceiver, do not
touch the connector pins at the end of the transceiver.
1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of
the strap to the ESD point on the switch.
2. Remove the transceiver from its bag.
3. Check to see whether the transceiver is covered with a rubber safety cap. If it is not, cover the transceiver
with a rubber safety cap.
WARNING: Do not leave a fiber-optic transceiver uncovered except when inserting
or removing a cable. The rubber safety cap keeps the port clean and prevents accidental
exposure to laser light.
4. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust
cover and save it in case you need to cover the port later. If you are hot-swapping a transceiver, wait
for at least 10 seconds after removing the transceiver from the port before installing a new transceiver.
5. Using both hands, carefully place the transceiver in the empty port. The connectors must face the
chassis.
CAUTION: Before you slide the transceiver into the port, ensure that the transceiver
is aligned correctly. Misalignment might cause the pins to bend, making the transceiver
unusable.
6. Slide the transceiver in gently until it is fully seated. If you are installing a CFP transceiver, tighten the
captive screws on the transceiver by using your fingers.
7. Remove the rubber safety cap when you are ready to connect the cable to the transceiver.
