Powering On an AC-Powered T640 Router
You can use this procedure for a router with either three-phase delta AC power supplies
or three-phase wye AC power supplies. To power on the AC-powered router:
1. Verify that the power supplies are fully inserted in the chassis and that the captive
screws on their faceplates are tightened.
2. Verify that the AC power cords are connected correctly.
3. Verify that an external management device is connected to one of the Routing Engine
ports on the CIP (AUXILIARY or CONSOLE).
NOTE: The management Ethernet port will not be functional until you
have completed the initial configuration.
