• When pressed with the Reset button in a specific pattern, clears
any configuration changes you may have made through the
switch console and SNMP management, and restores the factory
default configuration to the switch and the module. See “Restor-
ing the Factory Default Configuration” in chapter 7, “Trouble-
shooting” for the specific method to restore the factory default
configuration.
■
Self Test LED - When lit, indicates that the Management Module or
the switch in which the module is installed is undergoing its self test,
which occurs every time the switch is plugged into a power source,
or as a result of pressing the Reset button on the Management Module,
or from rebooting or resetting the switch from the switch console or
from network management.
■
Fault LED - When lit with the Self Test LED, indicates that the
Management Module is executing its self test. The self test normally
takes approximately 10 seconds. If the Self Test and Fault LEDs stay
on for longer than this, or if the Fault LED is flashing at any time, an
error has occurred on the module. See chapter 7, “Troubleshooting”
for more information on the LED and error recovery procedures.
■
Console RS-232 Port - This port is used to connect a console to the
switch, either directly using the serial cable supplied with the
Management Module, or through a modem connection. These connec-
tions are described in chapter 3, “The Switch Console”. The console
can be either a PC running a VT-100 terminal emulator, or a VT-100
terminal itself.
■
MAC Address - This is the unique hardware identity of the manage-
ment module. It is also used to identify the switch into which the
module is installed, and can be used in network connectivity tests
between the switch and other network devices. In an IPX network,
this address is also used as the Node Address part of the IPX network
address.
