Connecting Power to an AC-Powered MX480 Router with Normal-Capacity Power Supplies
CAUTION: Do not mix AC and DC power supply modules within the same
router. Damage to the router might occur.
You connect AC power to the router by attaching power cords from the AC power sources
to the AC appliance inlets located on the power supplies. For power cord and AC power
specifications, see
“AC Power Cord Specifications for the MX480 Router” on page 49 .
To connect the AC power cords to the router (see Figure 71 on page 206 ):
1.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2.
Locate the power cords shipped with the router, which should have a plug appropriate
for your geographical location (see
“AC Power Cord Specifications for the MX480
Router” on page 49 ).
3.
Move the AC input switch next to the appliance inlet on the power supply to the off
(O) position.
4.
Connect the power cord to the power supply.
5.
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 external circuit breaker.
6.
Route the power cord along the cable restraint toward the left or right corner of the
chassis. If needed to hold the power cord in place, thread plastic cable ties, which you
must provide, through the openings on the cable restraint.
7.
Verify that the power cord does not block the air exhaust and access to router
components, or drape where people could trip on it.
8.
Repeat Step 2 through Step 6 for the remaining power supplies.
