Chassis Controls and LEDs
The Maintenance button on the CPU module, as shown in Figure 2-3, is the only
chassis control. 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 status information
about the condition of the switch. 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 2-13 for information about power supply LEDs and to
”Port Status LED” on page 2-8 for information about the Port Status LED.
