Installing and Removing SFP Modules
This section describes how to install and remove SFP modules. The modules are inserted into the
SFP module slots on the front of the Cisco ASR 901 10G router. These field-replaceable modules
provide interfaces.
For a list of supported SFP modules, see the Release Notes for Cisco ASR 901 Series Aggregation
Services Router. Each port must match the wavelength specifications on the other end of the cable. For
reliable communications, the cable must not exceed 328 feet (100 meters).
For detailed instructions on installing, removing, and cabling the SFP module, see the SFP module
documentation.
Note The installation and removal steps given for SFP modules are also applicable for SFP+ modules.

Caution We 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.
