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.
NOTE: We recommend that you use only optical transceivers and optical
connectors purchased from Juniper Networks with your Juniper Networks
device.
CAUTION: If you are having a problem running a Juniper Networks device
that is using a third-party optic or cable, the Juniper Networks Technical
Assistance Center (JTAC) can help you diagnose the source of the problem.
Your JTAC engineer might recommend that you check the third-party optic
or cable and potentially replace it with an equivalent Juniper Networks optic
or cable that is qualified for the device.
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.
