Juniper Networks EX8208 User Manual

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 269).
Ensure that you have a rubber safety cap available to cover the transceiver.
Figure 62 on page 165 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.
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
hot-swapping a transceiver, wait for at least 10 seconds after removing the transceiver
from the port before installing a transceiver.
4.
Using both hands, carefully place the transceiver in the empty port. The connectors
must face the switch chassis.
CAUTION: Before you slide the transceiver into the port, ensure 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.
6.
Remove the rubber safety cap when you are ready to connect the cable to the
transceiver.
