How to Install or Remove a Physical Layer Interface Module (PLIM)
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 MSCs, always tighten the captive
installation screws on each newly installed PLIM
before
you insert another PLIM or MSC.
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 16-port
OC-48 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 ASR 14000 series 8-slot line card chassis.
Caution
The following warning applies to the removal of 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.
A physical layer interface module (PLIM) is paired with an MSC through the midplane of the chassis.
A PLIM provides the ability to choose several interfaces.

a 16 x OC-48c/STM-16c packet-over-SONET [POS]).
