Juniper EX4600 Series User Manual

Installing a Transceiver in an EX Series Switch
The transceivers for EX Series switches are hot-removable and hot-insertable
field-replaceable units (FRUs): You can remove and replace them without powering off
the switch or disrupting switch functions.
NOTE: After you insert a transceiver or after you change the media-type
configuration, wait for 6 seconds for the interface to display operational
commands.
Use only optical transceivers and optical connectors purchased from Juniper Networks
for your EX Series switches.
NOTE: On an EX3200 switch, if you install a transceiver in a 1-Gigabit Ethernet
uplink module port, a corresponding network port from the last four built-in
ports is disabled. For example, if you install a transceiver in the uplink module
port 3 (ge-0/1/2), then the built-in port 23 (ge-0/0/22) is disabled. The
disabled port is not listed in the output of show interface commands.
Before you begin installing a transceiver in an EX Series switch, ensure that you have
taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety
Guidelines and Warnings for EX Series Switches” on page 98).
Ensure that you have a rubber safety cap available to cover the transceiver.
Figure 37 on page 183 shows how to install a QSFP+ transceiver. The procedure is the
same for all types of transceivers.
To install a transceiver in an EX Series switch:
CAUTION: To prevent 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 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.
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. If you are
