How the Switch Reports Problems
The switch detects and processes errors as follows:
# The LEDs indicate problems with the ports and power. Table
4-1 and Table 4-2 describe the switch LEDs.
# In a TCP/IP environment, if you have configured the software
correctly, the management software triggers an SNMP trap
message. As a result, the software then sends traps to alert the
network manager when a trigger occurs. This type of software
configuration allows the network administrator to proactively
monitor the network.
Table 4-1, Table 4-2, and Table 4-3 list and describe the switch
and expansion module LEDs. As power is applied to the
switch, the Fault LED flashes as the switch runs internal self
tests.
