5.2 SwitchMaster™ Bridge Recovery Procedures

Recovery procedures for the SwitchMaster™ Bridge include:

Resetting the SwitchMaster™ Bridge

Verifying and optionally modifying Bridge Port Settings

Resetting the SwitchMaster™ Bridge

At power on or reset, the Status LEDs cycle through diagnostic test
patterns as internal SwitchMaster™ Bridge software tests: Flash, serial port,
dynamic RAM, static RAM, dual port memory, and each of the Ethernet
ports.  After the diagnostic test patterns, the Status LEDs display a pattern
in which four LEDs remain illuminated while four LEDs flash continuously
to indicate that the SwitchMaster™ Bridge is waiting for optional user
interrupt. Then the Status LEDs cycle in a steady roll to indicate that the
SwitchMaster™ Bridge is fully operational.

Reset the SwitchMaster™ Bridge in any of the following ways:

Press the reset button on the SwitchMaster™ Bridge.

Disconnect, then reconnect, power cord to the SwitchMaster™
Bridge.
