Expansion Module LEDs

When the ARN has an installed expansion module, its interface LEDs are visible
on the front panel. For the location of the optional ARN expansion module, see
Figure 1-4 on page 1-9.

Ethernet LEDs

Table 3-6

describes the expansion module LEDs for the second Ethernet2

interface.

Token Ring LEDs

Table 3-7

describes the expansion module token ring LEDs.

Note:

The ARN base module boots to a fully operational state before bringing

up expansion module interfaces.

Table 3-6.

Expansion Module Ethernet LEDs

LED

Meaning

Tx (Transmit)

Lights when the Ethernet interface is transmitting data over
the network.

Rx (Receive)

Lights when the Ethernet interface is receiving data from the
network.

Cl (Collision)

Lights when the Ethernet interface detects a collision on the
network.

Table 3-7.

Expansion Module Token Ring LEDs

LED

Meaning

RCVR (Receiver)

Lights when the token ring interface is connected to the
network.

NSRT (Insert)

Lights when you insert the ARN into the token ring network.

WFLT (Wire Fault)

Lights when the token ring hardware detects a wire fault
condition.
