Installing a Transceiver in an EX Series Switch

The SFP, SFP+, and XFP 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 213).

Ensure that you have a rubber safety cap available to cover the transceiver.

Figure 50 on page 137 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.
