Color Description
Unlit The port is not configured.
Solid Green A link is established on the OT interface.
Solid Amber The optical module associated with the port has a fault condition, or the
port is configured but the link is down.

Status and Activity LEDs

There are two kinds of LEDs for the network ports: port LEDs and Ethernet link LEDs. The
LEDs for the six physical ports indicate the link state of an OT interface. There are four
LEDs in between each port pair that indicate the link state of the associated ET interfaces,
see Figure 55 on page 95. To determine the link state of the OT interface, see
Table 42 on page 95.

You can also determine the configuration of the ET interfaces by examining the pattern
of the 4 Ethernet LEDs. See
those ET interfaces see Table 44 on page
