Cisco Systems UBR7100E manual Replacing the Chassis Cover, Inserting the Dimm

Chapter 6 Maintenance

Upgrading the SDRAM Memory Modules

Step 3 Hold the DIMM between your thumbs and forefingers and insert the connector edge of the DIMM straight into the socket. See Figure 6-10.

Caution When inserting the DIMM, use firm but not excessive pressure. If the socket is damaged, the chassis must be returned to the factory for repair.

Step 4 Gently push the DIMM into the socket until the socket latches close over the ends of the DIMM. (See Figure 6-11.) If necessary, rock the DIMM gently back and forth to seat it properly.

Step 5 When the DIMM is installed, check to see if it is seated properly. If the DIMM appears misaligned, carefully remove it and reseat it in the socket. Push the DIMM firmly back into the socket until first one and then the other latch moves into place.

Step 6 Repeat Step 2 through Step 5 to replace the second DIMM.

Replacing the Chassis Cover

To replace the cover on the Cisco uBR7100 series router, do the following:

Step 1 Using both hands, carefully hold the cover at an angle and insert it back into the cover tab slots at the rear of the chassis. See Figure 6-12.

Step 2 Settle the cover in place making sure that the side tabs are correctly inserted into the side slots. Step 3 Gently push the cover down until you hear it snap into place.

Step 4 Replace the screws in chassis cover (at the front). Do not overtighten the screws. (The recommended torque is 5 to 7 in. lbs [0.564 to 0.790 nm].)

Step 5 Replace the chassis in the rack (if necessary). See the “Rack-Mounting the Chassis” section on page 3-3.)
