Replacing Cisco 3745 Chassis Power Supplies

Installing a Cisco 3745 Chassis Power Supply

To install a chassis power supply, perform the following steps:

Step 1 Carefully slide the power supply straight into the router chassis. (See Figure 11 for reference.)

Step 2 Tighten the power supply retention screw at the front of the chassis. (See Figure 10 for reference.)

Step 3 If you are installing an AC power supply and your router uses –48V telephony power modules, install

the –48V telephony power module next to the power supply you installed, as described in Steps a and b.

If –48V telephony power modules are not required, proceed to Step 4.

a. Slide the –48V telephony power module straight into the router chassis. (See Figure 9 for reference.)

b. Tighten the captive screw that secures the –48V telephony power module in the chassis. (See

Figure 8 for reference.)

Step 4 Hold the fan tray straight out from the chassis, engage the hinges, and close the fan tray. (See Figure 12,

number 1 and number 2.)
