Step 6: Connect Power Cables
Depending on your configuration, your router uses either normal-capacity or high-capacity
AC or DC power supplies. Perform the appropriate procedures for each power supply in
your router.

Connect Power to an AC Router with Normal-Capacity Power Supplies
1. Locate the power cords, which should have a plug appropriate for your geographical
location (see the MX480 3D Universal Edge Router Hardware Guide).
2. Move the power switch on the power supply faceplate to the standby position.
3. Insert the power cord plug into an external AC power source receptacle.
NOTE: Each power supply must be connected to a dedicated AC power
feed and a dedicated customer site circuit breaker. We recommend that
you use a 15 A (250 VAC) minimum, or as permitted by local code.
4. Dress the power cord appropriately. Verify that the power cord does not block the air
exhaust and access to router components, or drape where people could trip on it.
5. Repeat Step 1 through Step 4 for the remaining power supplies.
Connect Power to an AC Router with High-Capacity Power Supplies
To install a high-capacity AC power supply:
1. Move the AC input switch next to the appliance inlet on the power supply to the off (O)
position.
2. Using both hands, slide the power supply straight into the chassis until the power
supply is fully seated in the chassis slot as shown in Figure 9 on page 18. The power
supply faceplate should be flush with any adjacent power supply faceplate or blank
installed in the power supply slot.
3. Tighten both captive screws at the bottom of the power supply.
4. Attach the power cord to the power supply.
5. Attach the power cord to the AC power source, and switch on the dedicated customer
site circuit breaker. Follow the instructions for your site.
6. Move the AC input switch next to the appliance inlet on the power supply to the on
(|) position and observe the status LEDs on the power supply faceplate. If the power
