Description
The switch module has passed the power-on self-test
(POST) with no critical faults and is operational.
The switch module has failed the POST or detected an
operational fault.
NOTE: When the Gigabit Ethernet switch module error
LED is lit, the system-error LED on the alarm panel is
also lit
There is a connection (or link) to a device using that
connector.
Data is being transmitted or received (that is, activity is
occurring) between that port and another device on the
network link.
