NOTE: If you have a Juniper J-Care service contract, register any addition, change,
or upgrade of hardware components at
https://www.juniper.net/customers/csc/management/updateinstallbase.jsp. Failure to do so
can result in significant delays if you need replacement parts. This note applies if
you change the type of power supply or add a new type of uplink module. It does
not apply if you replace these components with the same type of component.

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.
Use only optical transceivers and optical connectors purchased from Juniper Networks
for your EX Series switch.
NOTE: On an EX3200 switch, if you install a transceiver in a 1-gigabit 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 1-gigabit uplink module port 2 (ge-0/1/3),
then built-in port 23 (ge-0/0/23) 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 151).
Ensure that you have a rubber safety cap available to cover the transceiver.
Figure 33 on page 82 shows how to install an SFP transceiver. The procedure is the
same for all transceiver types.
To install a transceiver in an EX Series switch:
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.
