Reset
The Reset option (accessed from the main menu) allows you to reset a standalone
switch, a specific unit in a stack configuration, or an entire stack without erasing
any configured switch parameters. Resetting the switch takes approximately 5
seconds. During this time, the switch initiates a self-test that comprises various
diagnostic routines and subtests. The LEDs display various patterns to indicate
that the subtests are in progress. The results of the self-test are displayed briefly
(5 or 10 seconds) in the Self-Test screen (
Figure 3-39 ), which is followed by the
Nortel Networks logo screen ( Figure 3-40 ).

Note: The Self-Test screen remains displayed only if the self-test detects a
fatal error.
Note: The Self-Test screen for a switch that is participating in a stack
configuration includes an additional test: Cascade SRAM test.
