To ensure adequate space for additional PLIMs, MSCs, FPs, or LSPs, always tighten the captive installation
screws on each newly installed PLIM
before
you insert any additional PLIM, MSC, FP, or LSP. These screws
also prevent accidental removal and provide proper grounding and EMI shielding for the system.
Caution
Step 9
Install the optical modules, if applicable.
Step 10
Install the PLIM cable management bracket.
Step 11
Install the interface cables.
What to do next
Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected,
avoid exposure to laser radiation and do not stare into open apertures. Statement 70
Warning
Some PLIMs contain Class 1 lasers and some contain Class 1M. See the documentation for the specific PLIM
for details.
After performing this task, close the front (PLIM) side cosmetic doors (if installed).
Removing a PLIM
This section describes how to remove a PLIM from the LCC.
The following warning applies to removing very-short-reach (VSR) PLIMs: The router may indicate a hardware
failure if you do not follow proper procedures. Remove or install only one PLIM at a time. Allow at least 15
seconds for the router to complete the preceding tasks before removing or installing another PLIM.
Caution
We strongly recommend that you use the Cisco IOS XR shutdown command before removing a PLIM to
prevent anomalies when you reinstall a new or reconfigured PLIM.
Note
Prerequisites
Before performing this task, open the front (PLIM) side cosmetic doors (if installed).
