Installing a Transceiver in a QFX Series Device
Copyright © 2018, Juniper Networks, Inc.
The transceivers for the QFX Series are hot-removable and hot-insertable
field-replaceable units (FRUs). You can remove and replace them without powering off
the device or disrupting device functions.
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
Guidelines and Warnings for the QFX Series" on page
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.
Remove the transceiver from its bag.
1.
Check to see whether the transceiver is covered by a rubber safety cap. If it is not,
2.
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.
If the port in which you want to install the transceiver is covered with a dust cover,
3.
remove the dust cover and save it in case you need to cover the port later.
Using both hands, carefully place the transceiver in the empty port. The connectors
4.
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. Note that on QFX5100-48T
devices, the QSFP+ top and bottom ports have the same orientation for
inserting and removing transceivers. On all other QFX Series devices, the
ports are designed belly-to-belly, which requires you to turn the transceiver
over on the bottom port row. See
