Removing a Transceiver

The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable

units (FRUs). You can remove and replace them without powering off the device or disrupting device

functions.

NOTE:

After you remove a transceiver or when you change the media-type configuration, wait for

6 seconds for the interface to display the operational commands.

Before you begin removing a transceiver from a device, ensure that you have taken the necessary

precautions for the safe handling of lasers (see

“Laser and LED Safety Guidelines and Warnings” on page 220

).

Ensure that you have the following parts and tools available:

•

An antistatic bag or an antistatic mat

•

Rubber safety caps to cover the transceiver and fiber-optic cable connector

•

A dust cover to cover the port or a replacement transceiver

Figure 70 on page 165

shows how to remove a QSFP+ transceiver. The procedure is the same for all types

of transceivers except the QSFP28 and CFP transceivers.
