6 Cisco 3600 Series Memory Upgrade Conﬁguration Note

Removing the Cover

To gain access to memory in a Cisco 3600 series router, you must ﬁrst remove the chassis cover.

The following warning applies to routers with DC power supplies:

Warning Before performing any of the following procedures, ensure that power is removed from

the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that

services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of

the circuit breaker in the OFF position.

Follow this procedure to remove the chassis cover:

Step 1 Turn OFF power to the router.

Step 2 Remove all network interface cables from the rear panel.

Step 3 If the router is rack- or wall-mounted, remove it from the rack or wall.

Step 4 Place the router so the front panel is closest to you. Remove the three screws located on

top of the cover near the front edge. (Figure 2 shows these screws for the Cisco 3620

cover, and Figure 3 shows the screws for the Cisco 3640 cover.) Set the screws aside in a

safe place.

Step 5 Lift the front edge of the cover about 1 inch (2.5 cm) above the chassis, as shown in

Figure 1.

bottom. (See Figure 2 for the Cisco 3620 and Figure 3 for the Cisco 3640.)
