To replace an AC power supply, perform the following procedures:

1. Removing an SRX5600 Services Gateway AC Power Supply
2. Installing an SRX5600 Services Gateway AC Power Supply

Removing an SRX5600 Services Gateway AC Power Supply

The power supplies are located at the rear of the chassis. Each AC power supply weighs approximately 5.0 lb (2.3 kg).

Caution: Do not leave a power supply slot empty for more than 30 minutes while the services gateway is operational. For proper airflow, the power supply must remain in the chassis, or a blank panel must be used in an empty slot.

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 facility 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 electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3. Move the AC switch next to the appliance inlet on the power supply to the off position (O).
4. Unscrew the captive screws on the bottom edge of the power supply.
5. Remove the power cord from the power supply.
6. Pull the power supply straight out of the chassis.

To install an AC power supply (see Figure 2):

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. Move the AC switch next to the appliance inlet on the power supply to the off position (O).
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 (see Figure 2).
4. Tighten both captive screws at the bottom of the power supply.
5. Attach the power cord to the power supply.
6. Route the power cord along the cable restraint towards the left or right corner of the chassis. If needed to hold the power cord in place, thread plastic cable ties, which you must provide, through the openings on the cable restraint.
7. Attach the power cord to the AC power source, and switch on the dedicated facility circuit breaker for the power supply. Follow the ESD and connection instructions for your site.
8. Move the AC switch next to the appliance inlet on the power supply to the on position ( | ) and observe the status LEDs on the power supply faceplate. If the power supply is correctly installed and functioning normally, the AC OK and DC OK LEDs light steadily, and the PS FAIL LED is not lit.
