Installing the Cisco ASR 920 Series Router
This section provides procedures for installing and connecting SFP modules. Also, it provides the procedure
for removing SFP modules.
Install SFP Modules
The figure below shows an SFP module that has a bale-clasp latch.
Caution
We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached
because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module.
Disconnect all cables before removing or installing an SFP module.
Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules
more often than is absolutely necessary.
