Removing an SRX5800 Services Gateway AC Power Supply

Before you remove a power supply, be aware of the following:

Note: The minimum number of power supplies must be present in the services gateway at all times.

Caution: To maintain proper cooling and prevent thermal shutdown of the operating power supply unit, each power supply slot must contain either a power supply or a blank panel. If you remove a power supply, you must install a replacement power supply or a blank panel shortly after the removal.

Note: After powering off a power supply, wait at least 60 seconds before turning it back on.

To remove an AC power supply (see Figure 1):

1. Switch off the dedicated customer site circuit breaker for the power supply, and remove the power cord from the AC power source. Follow the ESD and disconnection instructions for your site.
2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3. 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.
4. 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.
5. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.
6. Pull the power supply straight out of the chassis. The power supply can weigh up to 12 lb (5.5 kg). Be prepared to accept its full weight.

   Warning: Do not touch the power connector on the top of the power supply (see Figure 2). It can contain dangerous voltages.

Installing an SRX5800 Services Gateway AC Power Supply

To install an AC power supply (see Figure 3):

1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Move the AC input switch in the chassis above the empty power supply slot to the off  (O) position.
3. If you are installing a high-capacity power supply, move the AC input switch on the faceplate of the power supply itself to the off  (O) position.
4. Ensure that the release lever below the empty power supply slot is locked in the counterclockwise position (see Figure 3).

   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.

5. 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 (see Figure 3). This tab is used to pull the power supply down in the chassis slot, prior to removing the power supply.

6. 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.
7. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.
8. If you are installing a high-capacity power supply, connect a power cord to the appliance inlet at the top edge of the power supply. For more information, see Connecting an SRX5800 Services Gateway AC Power Supply Cord.
9. Move the AC input switch in the chassis above the power supply to the on (—) position.
10. If you are installing a high-capacity power supply, move the AC input switch on the faceplate of the power supply itself to the on  (1) position.
11. Verify the following LED indications for each installed power supply:
    • For standard-capacity AC power supplies, verify that the AC OK and DC OK LEDs light steadily and the PS FAIL LED is not lit.
    • For high-capacity AC power supplies, verify that the DC OK LED lights steadily and the PS FAIL LED is not lit. In addition, the AC-1 OK LED should light green steadily if the upper AC feed (on the chassis above the power supply) is connected and receiving power, and the AC-2 OK LED should light green steadily if the lower AC feed (on the power supply itself) is connected and receiving power.

    Note: After a power supply is powered on, it can take up to 60 seconds for status indicators—such as the status LEDs on the power supply and the show chassis command display—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

    If any of the status LEDs indicates that the power supply is not functioning normally, repeat the installation and cabling procedures.
