Chassis Controls and LEDs
The Maintenance button on the CPU module, shown in Figure 2-3, is the only
chassis control and is used to reset a switch or to recover a disabled switch.
Power is applied to the switch logic circuitry when one or both power supply
modules are connected to a 110 or 230 VAC power source. The chassis LEDs are
located on the CPU module and provide information about the switch’s
operational status. The chassis LEDs provide information about the switch’s
operational status. The chassis LEDs include the Input Power LED, Heartbeat
LED, Over Temperature LED, and the Fan Fail LED. Refer to ”Power Supply
Modules” on page 2-12 for information about power supply LEDs and to ”Port
Status LED” on page 2-8 for information about the Port Status LED.

Maintenance Button
The Maintenance button is dual function control on the CPU module that resets
the switch or places 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 5-12 for information about maintenance mode.
