Chapter 5 Installing and Removing a Carrier Card

MSC Installation and Removal

This section provides step-by-step instructions for installing and removing an MSC.

Caution Insert or remove only one MSC at a time. Inserting or removing more than one MSC at a time can cause

the system to detect spurious hardware failures.

Warning

When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the

MSC. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the

midplane or backplane with your hand or any metal tool, or you could shock yourself.

To install and remove an MSC, refer to Figure 5-2 and Figure 5-3 and do the following:

Step 1 To insert the MSC, carefully align the edges of the MSC between the upper and lower edges of the

module slot, as shown in A of Figure 5-2.

Step 2 Ensuring that the MSC is properly aligned in the router slot, carefully slide the MSC into the module

slot until the MSC makes contact with the backplane.

Note The MSC ejector levers must be positioned at a 45-degree angle before the MSC makes contact

with the backplane.

Step 3 Push the MSC ejector levers in until the MSC is fully seated in the router backplane.

Note When the router chassis is fully populated, seating an MSC can be difficult. To properly seat the

MSC and avoid physical damage, loosen the locking captive installation screws on the

neighboring MSCs or line cards.

Caution Use of excessive force can damage the router or MSC.

Step 4 Tighten the locking captive installation screws on both sides of the MSC, using a screwdriver. The MSC

is now installed in the router module slot.

Step 5 To remove the MSC, loosen the locking captive installation screws using a screwdriver on both sides of

the MSC, as shown in A of Figure 5-3.

Step 6 Pull out the MSC ejector levers, as shown in B of Figure 5-3, and carefully slide the MSC out of the

module slot. If you are removing a blank module filler plate, pull the blank module filler plate

completely out of the module slot.
