Removing Components from the SRX5800 Chassis Before Installing It in
the Rack
Before installing the services gateway in the rack, you must first remove components from the chassis to
make it light enough to safely maneuver into the rack. With components removed, the chassis weighs
approximately 150 lb (68 kg). You reinstall the components into the chassis after it is installed in the rack.

Removing the Power Supplies Before Installing the SRX5800 Services Gateway Chassis
Remove the leftmost power supply first and then work your way to the right. To remove each AC or DC
power supply (see Figure 88 on page
1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on
the chassis.
2. Switch off the services gateway power supplies:
For an AC-powered services gateway, move the AC input switch on the chassis above each AC power
supply to the off (O) position. If the services gateway is equipped with high-capacity AC power
supplies, you must also move the AC input switch on each power supply to the off (O) position.
For DC-powered services gateway, move the DC circuit breaker on each power supply faceplate to
the off (O) position.
We recommend switching off the power supplies even though they are not connected to power sources.
3. While grasping 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
counterclockwise until it stops.
4. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding
hole in the chassis.
5. Pull the power supply straight out of the chassis.
