Chassis Controls and LEDs
The Reset/Force PROM button shown in Figure 2-2 is the only chassis control
and is used to recover a disabled switch. The chassis LEDs provide information
about the switch’s operation status. These LEDS include the Over Temperature
LED, Fan Fail LED, Heartbeat LED, and the Input Power LED. To apply power to
the switch, plug the power cord into the switch AC power receptacle and into a
110 or 230 VAC power source.

Reset/Force PROM Button
The Reset/Force PROM button is a dual-function momentary switch on the front
panel. Its purpose is to reset the switch or to place the switch in force PROM
mode. Force PROM mode causes the switch to access PROM when flash
memory or the resident configuration file is corrupted. Placing the switch in force
PROM mode forces the default IP address of 10.0.0.1. To exit force PROM mode,
reset the switch either by pressing the Reset/Force PROM button or power cycling
the switch. Refer to ”Recovering a Switch” on page 5-9 for more information about
using force PROM mode.
