Chapter 4 Installing and Removing Line Cards, PLIMs, and Associated Components
How to Install or Remove a Physical Layer Interface Module
Step 8 To seat the card in the midplane connector, grasp both card ejector levers and pivot them inward toward
the handle in the card carrier until they are flush against the front edge of the card carrier.
Step 9 Partially tighten the two captive screws on the front panel of the card (either by hand or with the
screwdriver) to make sure that they are both engaged.
Step 10 Tighten the captive screws on the PLIM.
Caution To ensure adequate space for additional PLIMs or line cards, always tighten the captive
installation screws on each newly installed PLIM before you insert another PLIM or line card.
These screws also prevent accidental removal and provide proper grounding and EMI
shielding for the system.
Step 11 Install the SFP optical modules, if applicable (in a PLIM that uses an SFP module, such as the a 14-port
10-GE XFP PLIM).
Step 12 Install the PLIM cable management bracket.
Step 13 Install the interface cables.
Warning
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
Some PLIMs contain Class 1 lasers, and some contain Class 1M. See the documentation for the specific
PLIM for details.
What to Do Next
After performing this task, replace any grilles and chassis doors.
Removing a PLIM
This section describes how to remove a PLIM from the Cisco CRS 8-slot line card chassis. See
Figure 4-32 for an example of a typical PLIM.
Caution The system 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 system to complete the preceding tasks before
removing or installing another PLIM.
Note We strongly recommend that you use the shutdown command before removing a PLIM to prevent
anomalies when you reinstall a new or reconfigured PLIM.
Prerequisites
Before performing this task, remove any front cover plates.
