Replacing Cisco 3745 Chassis Power Supplies

Step 5 Tighten the two captive screws located inside the access door. (See Figure 6 for reference.)

Step 6 Place the router so the rear panel is facing toward you.

Step 7 Install the two retaining screws at the rear of the chassis. (See Figure 5 for reference.)

Step 8 If you are installing a PWR-3745-DC-U= universal DC power supply, apply the input voltage label

(supplied) over the existing input voltage label on the rear of the chassis.

Step 9 Connect the network interface cables on the rear panel.

Note Cisco 3745 routers require a reliable earth ground connection using a ground lug and AWG 16 (13mm

)

wire. If your router does not have an earth ground connection, refer to the Cisco 3745 Quick Start Guide

that was provided with your router, or refer to the Cisco 3700 Series Hardware Installation Guide on

Cisco.com, for instructions on installing an earth ground.

Step 10 Connect your router to the appropriate AC or DC power source.

If your router uses DC power, proceed to the “Connecting DC-Input Power” section.

If your router uses AC power, connect the AC power cord. The following warning applies to AC power.
