Installing and Upgrading Memory in Cisco 1700 Series Routers

OL-3892-02

Closing the Chassis of a Desktop Router

Step 4 Position the SIMM so that the indexing slot in the connector (bottom edge) of the SIMM is lined up with

the indexing tab inside the SIMM slot. Tilt the SIMM 45 degrees toward the rear of the router, and insert

it into the slot. (See Figure 13 below.) Rock it into its vertical position, using the minimum force

necessary. When the SIMM is properly seated, the connector springs click into place.

Figure 13 Installing a SIMM

Closing the Chassis of a Desktop Router

After installing memory on the motherboard, follow these steps to close the chassis:

Step 1 If you disconnected the fan from the motherboard as described in the “Opening the Chassis of a Desktop

Router” section on page 9, reconnect the fan cable to the connector labeled FAN on the motherboard.

Note The fan does not run continuously; it only turns on when the internal temperature of the router

becomes too warm.

Step 2 Locate the posts that protrude from the inside of the chassis cover and corresponding openings on the

chassis bottom.

Step 3 Line up the posts with the corresponding openings, as shown in Figure 14 on page 20, and carefully slide

the posts into the openings, taking caution not to damage the router motherboard with the posts.

Caution Be careful not to damage the slot guides on the DIMM socket. If the guides are open, caution is necessary

while installing the top of the chassis because improper installation can break the guides off the DIMM

socket. (The Cisco 1751 router is shipped with a blank DIMM in the slot to keep the guides up and out

of the way.)

Step 4 Replace the screws that you removed when opening the chassis. (See Figure 1 on page 10.)
