Before you begin installing a transceiver in a QFX Series device, ensure that you have
taken the necessary precautions for safe handling of lasers (see
“Laser and LED Safety
Guidelines and Warnings for the QFX Series” on page 120 ).
Ensure that you have a rubber safety cap available to cover the transceiver.
To install a transceiver in the QFX Series:
CAUTION: To avoid electrostatic discharge (ESD) damage to the transceiver,
do not touch the connector pins at the end of the transceiver.
1.
Remove the transceiver from its bag.
2.
Check to see whether the transceiver is covered by 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.
3.
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.
4.
Using both hands, carefully place the transceiver in the empty port. The connectors
must face the device 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.
5.
Slide the transceiver in gently until it is fully seated. See Figure 59 on page 208 for an
example of inserting a SFP transceiver. Figure 60 on page 208 , and Figure 61 on page 208 ,
are examples of inserting QSFP+ transceivers into different QFX Series product SKU
devices.
6.
Remove the rubber safety cap when you are ready to connect the cable to the
transceiver.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables
connected to transceivers emit laser light that can damage your eyes.
