Chapter 6 Installing and Removing a Shared Port Adapter

Online Insertion and Removal

The Cisco 7304 router supports OIR of a SPA independently of removing the MSC. This means that an

MSC can remain installed in the router with one SPA remaining active while you remove another SPA

from one of the MSC subslots. If you are not planning to immediately replace a SPA into the MSC, then

be sure to install a SPA blank filler plate in the subslot. The MSC can be inserted and removed using

OIR without removing the SPAs in the installed subslots and the MSCs should always be fully installed

with either functional SPAs or SPA blank filler plates.

For additional information regarding OIR of a SPA in an MSC, see the Cisco 7304 Router Modular

Services Card and Shared Port Adapter Software Configuration Guide.

SPA Installation and Removal

You can install two half-height SPAs in an MSC-100. This section provides step-by-step instructions for

removing and installing a SPA in an MSC.

Warning

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

SPA. 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 remove and install a SPA in an MSC, refer to Figure 6-2 and Figure 6-3 and do the following:

Note The MSC can be inside or outside the router slot when the SPA is being installed or removed.

Caution Remove all cables from the SPAs prior to installation. Do not install cables into the SPAs until the SPA

is properly seated in the MSC and the locking captive installation screws on the SPA are in their locked

positions.

Step 1 Remove all cabling from the SPA if any cabling has been connected to the SPA.

Step 2 Remove the SPA from the MSC. To remove the SPA from the MSC, unlock the SPA locking captive

installation screws from their locked positions using a screwdriver as shown in 1 of Figure 6-2 to the

unlocked positions.

Step 3 Grasp the handle of the SPA and pull the SPA from the MSC.

Step 4 To insert the SPA in the MSC, locate the guide rails inside the MSC that hold the SPA in place. They are

at the top left and top right of the SPA slot and are recessed about an inch, as shown in 1 of Figure 6-3.

Step 5 Carefully slide the SPA all the way into the MSC until the SPA is firmly seated in the SPA interface

connector. When fully seated, the SPA might be slightly behind the MSC faceplate.

Step 6 After the SPA is properly seated, use a screwdriver to turn the SPA locking captive installation screws

to their locked positions, as shown in 2 of Figure 6-3.

Figure 6-2 illustrates how to remove a SPA from an MSC and Figure 6-3 illustrates how to install a SPA

into an MSC.
