Introduction
This chapter describes the front panel LEDs and back panel connectors. The front panel contains LEDs for
the EtherNet (LAN), WAN Link, and the self test fail and power. The back panel connectors are the Ethernet
10BASE-T and BNC (10Base2) connections for the LAN, the WAN Link connection (RS232/ V.35) for the WAN
communications device, and the command port connection for configuration of the RouteFinder
100
.
2.2
Front Panel
The front panel contains three groups of LEDs that provide the status of the LAN connection, link activity, and
general status of the RouteFinder
100
. The EtherNet LEDs display the activity of the LAN in whether the
RouteFinder
100
is connected to the LAN, transmitting or receiving packets, and if a collision is in progress. The
WAN LEDs display the status of the link (i.e., ready to transmit or receive serial data and if an external
communications device with a V.35 interface is connected to the RouteFinder
100
. The last group of LEDs
indicate whether the self test passed or failed and if the power On/Off switch on the back of the RouteFinder
100
is turned On.

ETHERNET
RCV
Receive indicator blinks when packets are being received from the local area network.
XMT
Transmit indicator blinks when packets are being transmitted to the local area network.
COL
Collision indicator lights when a collision is in progress, that is, when two nodes are transmitting
packets at the same time.
LNK
Link indicator lights indicating that the RouteFinder
100
is connected to the local area network.
WAN Link
RCV
Receive indicator blinks when the link is receiving data.
XMT
Transmit indicator blinks when the link is transmitting data.
CTS
Clear To Send indicator lights when the link is ready to transmit data.
RTS
Request to Send indicator lights then the link is ready to receive data.
CD
Carrier Detect indicator lights when the RouteFinder
100
detects a carrier signal.
V.35
The V35 indicator lights when the link is configured for a V.35 interface. That is, the shunt for the link
is in the V.35 position.
FAIL
Fail indicator lights when a self test fails to complete as expected.
POWER The power indicator lights when the On/Off Switch is in the ON position.
