2.1.1

Power Switches

Each power supply has an On/Off switch that controls power to the switch logic circuitry. To apply power to the switch, place both switches in the On position.

2.1.2

Maintenance Button

The Maintenance button is a momentary switch on the front panel. Its purpose is to place the switch in maintenance mode. Maintenance mode sets the IP address to 10.0.0.1 and provides access to the switch for maintenance purposes when flash memory or the resident configuration file is corrupted. Refer to ”Recovering a Switch” on page 5-12for information about maintenance mode.

To place the switch in maintenance mode, do the following:

1.Isolate the switch from the fabric. Open a Telnet session, and enter the Shutdown command. Refer to ”Shutdown Command” on page B-65.

2.Place both power supply switches in the Off position.

3.Press and hold the Maintenance button with a pointed tool for a few seconds, then place one of the power supply switches in the On position. You can release the Maintenance button after the Input Power LED illuminates. When the switch is in maintenance mode, the Heartbeat LED illuminates continuously. Refer to ”Chassis LEDs” on page 2-3for information about the Input Power LED and the Heartbeat LED.

To return to normal operation, power cycle the switch.
