Asynchronous Network Module LEDs
All network modules have an enable (EN) LED. This LED indicates that the module has
passed its self-tests and is available to the router.
Each port on an asynchronous network module also has a green status LED to indicate that
the port is connected to the network. These LEDs are grouped in blocks of eight to the left
of each module, and labeled with the port numbers. (See Figure 6-9 and Figure 6-10.)
