Cisco Cisco CRS-X Multishelf System Installation Guide

To ensure adequate space for additional PLIMs, always tighten the captive installation screws 
on each newly installed PLIM before you insert another PLIM. These screws also prevent 
accidental removal and provide proper grounding and EMI shielding for the system.

(OC-48c/STM-16c POS/DPT PLIMs only) Install the SFP modules.

Install the interface cables. We recommend that you clean the fiber-optic connections before attaching 
the cables. See the URL 

 for cleaning 

instructions.

If this PLIM is new, configure it for operation. For instructions, see Cisco IOS XR Interface and 
Hardware Component Configuration Guide and the Cisco IOS XR Interface and Hardware Component 
Command Reference

Because invisible radiation may be emitted from the aperture of the port when no fiber cable is 
connected, avoid exposure to radiation and do not stare into open apertures. Statement 125

You can also keep the dust caps or covers on the laser optical bores to avoid radiation exposure. 

A small form-factor pluggable (SFP) module provides the optics ports for some types of PLIMs. An SFP 
module is installed into a port on the PLIM. The SFP module has a bale-clasp latch that you use to install 
or remove the module (see
