Installing and Removing MSCs, PLIMs, and Associated Components
Visually inspect the connector on the card before you insert it into the chassis. Do not attempt to install
Step 5
a card with a damaged connector, as this action may damage the chassis midplane pins.
Step 6
Use both hands while inserting an MSC. Use one hand on the faceplate and the other hand along the base
of the MSC to guide it into a slot.
Step 7
Orient the MSC so that the PCB faces left and the carrier is to the right; if the card does not slide easily
into the slot, the orientation may be wrong and the misorientation rejection flange is stopping the card
from going into the slot. Reorient the MSC, if necessary.
Make sure that the ejector levers are oriented properly to engage with the pin as the MSC slides into the
Step 8
slot. Carefully slide the MSC into the slot until the ejector levers engage the catches, then stop.
Simultaneously pivot the ejector levers toward the faceplate of the MSC. Do not force the MSC; the
Step 9
ejector levers properly seat the MSC against the midplane.
Note
Partially tighten the two captive screws on the front panel of the card (either by hand or with the
Step 10
screwdriver) to make sure that they are both engaged.
Use a screwdriver to fully tighten the captive screws next to each MSC ejector lever to ensure proper
Step 11
EMI shielding and to prevent the MSC from becoming partially dislodged from the midplane.
Caution
Attach the bracket to the MSC; use the screws that came with it.

Removing an MSC

This section describes how to remove an MSC from the Cisco ASR 14000 series 8-slot line card chassis.
For more detailed information on the MSC, see Cisco ASR 14000 Series Router 8-Slot Line Card Chassis
System Description.
The MSC is a Layer 3 forwarding engine in the Cisco ASR14000 Series routing system (see
Figure
to provide a variety of interfaces.
OL-16973-01
If the captive screws are difficult to tighten, check to ensure that each ejector lever is properly
secured to each catch and that the MSC is properly seated in the slot.
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.
Place the impedance carrier in an antistatic bag for storage and future use.
Replace any front cover cosmetic plates and verify that the card has been installed properly (see the
"Verifying the Installation of an MSC" section on page
If you are performing the initial installation of the system, install the RP cards (see the
Install or Remove an RP Card or DRP PLIM" section on page
4-25). An MSC can be paired with different types of physical layer interface modules (PLIMs)
