Replacing an SRX5800 Services Gateway AC Power Supply Cord
To replace an SRX5800 Services Gateway AC power supply cord, perform the following procedures:
- Disconnecting an SRX5800 Services Gateway AC Power Supply Cord
- Connecting an SRX5800 Services Gateway AC Power Supply Cord
Disconnecting an SRX5800 Services Gateway AC Power Supply Cord
To disconnect an AC power cord:
- Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
Move the AC input switch nearest to the appliance inlet for the power cord you are replacing to the off (O) position:
- For standard-capacity AC power supplies, there is only one AC input switch for each power supply; it is located next to the appliance inlet on the chassis above the power supply.
- For high-capacity AC power supplies, there is one AC input switch for each of the two appliance inlets. One is located next to the AC inlet on the chassis above the power supply, and the other is located next to the appliance inlet on the power supply itself.
- Unplug the power cord from the power source receptacle.
- Unplug the power cord from the appliance inlet on the chassis or power supply.
Connecting an SRX5800 Services Gateway AC Power Supply Cord
 | Note: Power cords are not supplied with the services gateway. You must order the power cords separately. |
To connect an AC power cord:
- Locate a replacement power cord with the type of plug appropriate for your geographical location.
- 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 AC input switch nearest to the appliance inlet for the power cord you are replacing is in the off (O) position:
- For standard-capacity AC power supplies, there is only one AC input switch for each power supply; it is located next to the appliance inlet on the chassis above the power supply.
- For high-capacity AC power supplies, there is one AC input switch for each of the two appliance inlets. One switch is located next to the AC inlet on the chassis above the power supply, and the other is located next to the appliance inlet on the power supply itself.
- Plug the replacement power cord into the corresponding appliance inlet located in the chassis directly above the power supply, or, in the case of a high-capacity AC power supply, at the top edge of the power supply itself.
- Insert the power cord plug into an external AC
power source receptacle.
Note: Each power supply must be connected to a dedicated AC power feed and a dedicated customer site circuit breaker. We recommend that you use a 15 A (250 VAC) minimum, or as required by local code.
- Dress the power cord appropriately. Verify that the power cord does not block the air exhaust and access to services gateway components, or drape where people could trip on it.
Move the AC input switch nearest to the appliance inlet for the power cord you are replacing to the on (|) position:
- For standard-capacity AC power supplies, there is only one AC input switch for each power supply; it is located next to the appliance inlet on the chassis above the power supply.
- For high-capacity AC power supplies, there is one AC input switch for each of the two appliance inlets. One is located next to the AC inlet on the chassis above the power supply, and the other is located next to the appliance inlet on the power supply itself.
Verify the following LED indications for the power supply for which you replaced the power cord:
- 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.
