Removing a Transceiver from 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 remove a transceiver or when you change the media-type
configuration, wait for 6 seconds for the interface to appear in operational
commands.
Before you begin removing a transceiver from 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 139).
Ensure that you have the following parts and tools available:
•
An antistatic bag or an antistatic mat
•
Needlenose pliers
•
Rubber safety caps to cover the transceiver and fiber-optic cable connector
•
A dust cover to cover the port
Figure 45 on page 117 shows how to remove an SFP transceiver. The procedure is the
same for all transceiver types.
To remove a transceiver from an EX Series switch:
1. Place the antistatic bag or antistatic mat on a flat, stable surface.
2. Label the cable connected to the transceiver so that you can reconnect it correctly.
