Operating the ARN

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.

Note: The ARN base module boots to a fully operational state before bringing up expansion module interfaces.

Ethernet LEDs

Table 3-6 describes the expansion module LEDs for the second Ethernet2 interface.

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.

Token Ring LEDs

Table 3-7 describes the expansion module token ring LEDs.

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.
