Modules Internal to the Cisco 1805 Cable Router

This section tells how to install a small-outline dual in-line memory module (SODIMM) and an advanced integration module (AIM) in the Cisco 1805 cable router. It contains the following subsections:

•Opening the Chassis, page 8-2

•Locating Modules, page 8-4

•Installing a SODIMM, page 8-5

•Installing an AIM, page 8-6

•Closing the Chassis, page 8-10

All the module replacement procedures in this section require removal of the chassis cover. Before you perform any of the module replacement procedures, disconnect the power and remove the cover as described in the “Opening the Chassis” section on page 8-2. After you complete the module replacement procedures, install the chassis cover as described in the “Closing the Chassis” section on page 8-10.

To open the chassis, follow these steps. You need a number one Phillips screw driver to complete this procedure.

Step 1 Make sure that the router is turned off and is disconnected from AC power.

Step 2 Turn the router upside-down, and rest the top of the router on a flat surface.

Step 3 Use the Phillips screwdriver to remove the screw that holds the top and bottom of the chassis together. (See Figure 8-1.)
