Powering On an AC-Powered Services Gateway

To power on an AC-powered services gateway:

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. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Verify that the power supplies are fully inserted in the chassis.
3. Verify that the AC power cord is securely inserted into the appliance inlet.
4. Verify that an external management device is connected to one of the Routing Engine ports (AUX, CONSOLE, or ETHERNET). For more information about connecting management devices, see Connecting the Services Gateway to Management and Alarm Devices.
5. Turn on the power to the external management device.
6. Switch the AC switch on each power supply to the on position (|) and observe the status LEDs on each power supply faceplate. If an AC 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.

   If any of the status LEDs indicates that the power supply is not functioning normally, repeat the installation and cabling procedures described in Replacing Power System Components.

   Note: After powering off a power supply, wait at least 60 seconds before turning it back on. After powering on a power supply, wait at least 60 seconds before turning it off. If the system is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, see . 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.

7. On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.
