Reinstalling the Power Supplies After Installing the MX480 Router with a Lift
Reinstall the rightmost power supply first and then work your way to the left. To reinstall
the AC or DC power supplies, follow this procedure for each power supply (see
Figure 54 on page 186 , which shows the installation of the DC power supplies):
1.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2.
On an AC-powered router, switch the AC input switch on each power supply to the
off (
O
) position. On a DC-powered router, Move the DC circuit breaker on each DC
power supply to the off (
O
) position.
We recommend this even though the power supplies are not connected to power
sources.
3.
Using both hands, slide the power supply straight into the chassis until the power
supply is fully seated in the chassis slot. The power supply faceplate should be flush
with any adjacent power supply faceplate or blank installed in the power supply slot.
4.
Tighten the captive screws.
