Install a Transceiver
Before you install a transceiver in a device, ensure that you have taken the necessary precauons for
safe handling of lasers (see Laser and LED Safety Guidelines and Warnings).
Ensure that you have a rubber safety cap available to cover the transceiver.
The transceivers for Juniper Networks devices are hot-removable and hot-insertable eld-replaceable
units (FRUs). You can remove and replace the transceivers without powering o the device or disrupng
the device funcons.
NOTE: Aer you insert a transceiver or aer you change the media-type conguraon, wait for
6 seconds for the interface to display operaonal commands.
NOTE: We recommend that you use only opcal transceivers and opcal connectors purchased
from Juniper Networks with your Juniper Networks device.
CAUTION: The Juniper Networks Technical Assistance Center (JTAC) provides
complete support for Juniper-supplied opcal modules and cables. However, JTAC does
not provide support for third-party opcal modules and cables that are not qualied or
supplied by Juniper Networks. If you face a problem running a Juniper device that uses
third-party opcal modules or cables, JTAC may help you diagnose host-related issues if
the observed issue is not, in the opinion of JTAC, related to the use of the third-party
opcal modules or cables. Your JTAC engineer will likely request that you check the
