Installing the Cisco 3631 Power Supply
To install a power supply in the chassis, follow these steps:
Step 1 Place the power supply in the chassis, with the power supply rear panel slightly separated from the
chassis rear panel. This position allows the hooks in the chassis to engage the cutouts in the bottom of
the power supply. (See Figure 7 and Figure 8.)
Step 2 Slide the power supply toward the rear of the chassis, engaging the hooks in the chassis.
Step 3 Replace the external rear mounting screws. (See Figure 6.)
Step 4 Insert the large power connector into the receptacle on the motherboard. (See Figure 5.)
Step 5 Reinsert the Compact Flash memory card in the receptacle and screw in the Compact Flash memory
retention screw.
Replacing the Router Cover
After you finish replacing the power supply, follow these steps to replace the cover:
Step 1 Place the chassis bottom so the front panel is closest to you.
Step 2 Hold the cover so the tabs at the rear of the cover are aligned with the chassis bottom.
