Upgrading System Memory in Cisco 3745 Routers

Replacing Connections to the Router

To make final connections to the router, follow these steps:

Warning

Read the installation instructions before connecting the system to the power source.

Statement 1004

Step 1 Replace all network connections.

Step 2 Do one of the following:

• AC-powered router: Plug the power cord into a 3-terminal, single-phase power source that

provides power within the acceptable range (100 to 240 VAC, 50 to 60 Hz).

• DC-powered router: Remove the tape from the circuit breaker switch handle and reinstate power

by moving the handle of the circuit breaker to the ON position.

Step 3 Turn on the power switch. The power LED on the front panel of the router should come on.

Step 4 Check the Sys LED on the right side of the front panel to verify that it goes on after a few seconds delay

when booting.

Step 5 If you have problems, see the “Obtaining Technical Assistance” section on page 28.

Step 6 Proceed to the “Recovering Compact Flash Memory and System Images” section on page 27.

Statement 1

Removing the Cisco 3745 Mainboard Tray

To remove the mainboard tray, follow these steps:

Step 1 Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the

equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact with the

connectors.

Step 2 Turn off the power, but do not unplug the power cord.

Caution The Cisco 3745 router can have more than one power supply. Be sure that all power supplies are powered

off and that all LEDs are dark.

Step 3 Place the router on a flat surface so that the front panel faces you, and open the small access door at the

right-hand edge of the front panel.

Step 4 Loosen the two captive screws located behind the access door. (See Figure 6.)
