LEDs
Your EtherFast 10/100 4-Port Analog Router is
equipped with eleven “smart” LEDs that you can use
for diagnostic purposes. They are explained below.
• Modem Activity
These LEDs will light up if the corresponding modem
port is currently hosting an active modem connection.
The LED flickers when the modem transfers or
receives data. The LED will be off the rest of the time
(even if the modem is connected and turned on).
• LAN Link/Act/Speed
These LEDs will light up red if a 100Mbps connection
is detected on the corresponding RJ-45 10/100 port. If
a 10Mbps connection is detected, the light will be
green. The LEDs will flicker when activity is detected
on any of the 10/100 connections.
• Collision
The 10M LED will light up when collisions are detect-
ed on the router’s 10Mbps backplane. The 100M LED
will light up when collisions are detected on the
router’s 100Mbps backplane.
• Power
Indicates that the router is powered on.
