Switch Module Controls and LEDs
Switch Module Controls and LEDs
The switch module LEDs provide information about the switch module’s
operational status. These LEDS include the Identifier LED, System Fault LED,
and Input Power LED. The Maintenance button shown in Figure 1-2 is the
only switch module control and is used to reset a switch module or to recover
a disabled switch module.
Figure 1-2. Switch Module Controls and LEDS
Maintenance Button
The Maintenance button is a dual-function momentary switch on the front
panel. Its purpose is to reset the switch module or to place the switch module
in maintenance mode. Maintenance mode sets the IP address to 10.0.0.1 and
provides access to the switch module for maintenance purposes when flash
memory or the resident configuration file is corrupted. Refer to “Recovering a
Switch Module” on page 4-4 for more information about using maintenance
mode.
Resetting a Switch
To reset the switch module, use a pointed tool to momentarily press and
release (less than 2 seconds) the Maintenance button. The switch module will
respond as follows:
1. All switch module LEDs will illuminate, then the System Fault LED
extinguishes leaving only the Input Power LED illuminated.
2. After approximately 1 minute, the power-on self test (POST) begins.
3. When the POST is complete, the Input Power LED is illuminated.
Placing the Switch in Maintenance Mode
To place the switch module in maintenance mode, do the following:
1. Isolate the switch module from the fabric.
2. Press and hold the Maintenance button with a pointed tool for 2–4
seconds.
3. After a few seconds, the POST begins illuminating all switch module
LEDs.
4. When the POST is complete, the switch module LEDs extinguish.
