Juniper MX960 - Reinstalling the Power Supplies after Installing the MX960 Router with a Lift

Reinstalling the Power Supplies After Installing the MX960 Router with a Lift
Reinstall the rightmost power supply first and then work your way to the left. To reinstall the AC, DC, or
universal power supplies, follow this procedure for each power supply (see Figure 104 on page 322,
Figure 105 on page 323, and Figure 61 on page 268, which shows the installation of the DC power supplies):
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 104 on page 322 which shows the
installation of the DC power supplies):
1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end of the strap to the ESD point on the chassis.
2. For an AC-powered router, move the AC input switch in the chassis above the power supply slot to
the off (O) position. For a DC-powered router, move the DC circuit breaker on the power supply to
the off (O) position.
We recommend this even though the power supplies are not connected to power sources.
3. Ensure that the release lever below the empty power supply slot is locked in the counterclockwise
position (see Figure 104 on page 322).
If necessary, pull the spring-loaded locking pin in the release lever away from the chassis and turn the
release lever counterclockwise until it stops. Let go of the locking pin in the release lever. Ensure that
the pin is seated inside the corresponding hole in the chassis.
4. 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 faceplates.
The small tab on the metal housing that is controlled by the release lever must be inside of the
corresponding slot at the bottom of the power supply. This tab is used to pull the power supply down
in the chassis slot, prior to removing the power supply.
5. While firmly pushing the handle on the power supply faceplate with one hand, use your other hand to
pull the spring-loaded locking pin in the release lever away from the chassis and turn the release lever
clockwise until it stops.
6. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding
hole in the chassis.
