Reinstalling Components in the MX480 Router After Installing It Without a Lift
After the router is installed in the rack, you reinstall the removed components before
booting and configuring the router. The following procedures describe how to reinstall
components in the chassis, first in the rear and then in the front:
1. Reinstalling the Power Supplies After Installing the MX480 Router Without a
Lift on page 91
2. Reinstalling the Fan Tray After Installing the MX480 Router Without a Lift on page 92
3. Reinstalling the SCBs After Installing the MX480 Router Without a Lift on page 93
4. Reinstalling the DPCs After Installing the MX480 Router Without a Lift on page 94
5. Reinstalling the FPCs After Installing the MX480 Router Without a Lift on page 95
Reinstalling the Power Supplies After Installing the MX480 Router Without 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 92 , which shows the installation of the DC power supplies):
1. Attach an electrostatic discharge (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.
