Reinstalling Power Supplies After Installing the SRX5800 Services Gateway Chassis
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 94 on page 227 , 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.
Verify that the power supplies are switched off:
•
For an AC-powered services gateway, verify that the AC input switch on the chassis above each AC
power supply is in the off (O) position. If the services gateway is equipped with high-capacity AC
power supplies, also verify that the AC input switch on each power supply is in the off (O) position.
•
For DC-powered services gateway, verify that the DC circuit breaker on each power supply faceplate
is in the off (O) position.
We recommend verifying that the power supplies are switched off even though they are not connected
to power sources.
2. Ensure that the release lever below the empty power supply slot is locked in the counterclockwise
position (see Figure 94 on page 227 ).
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.
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 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.
4. 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.
5. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding
hole in the chassis.
