EtherFast Cable/DSL Routers
Link/Act
Green. The Link/Act LED serves two purposes. If the LED
is continuously lit up, the Router is successfully connected
to a device through the LAN port. If the LED is flickering,
the Router is actively sending or receiving data through the
LAN port.
Full/Col
Green. The Full/Col LED also serves two purposes. If this
LED remains lit, a LAN port connection is being success-
fully maintained. If the LED flickers, the connection is
experiencing collisions. Infrequent collisions are normal.
If this LED flickers too often, there may be a problem with
your connection. See Troubleshooting on page 56 if you
encounter problems.
10/100
Orange. The 10/100 LED lights up when a successful
100Mbps connection is made through the corresponding
port.
If a connection is running at 10Mbps, the 10/100 LED will
not light up.
The WAN Indicators
Link
Green. The Link LED lights up when a successful connec-
tion is made between the Router and your Broadband
device or network.
Act
Green. The Act LED flickers when the Router is sending or
receiving data over the broadband WAN port.
Diag
Red. The Diag LED lights up when the Router goes through
its self-diagnostic test during boot-up. It will turn off upon
successful completion of the diagnosis. The Diag LED also
lights up when you press the Reset button or click Apply to
save any changes made in the Web-based Utility.
If this LED stays on for an abnormally long period of time,
see the Troubleshooting section.

The Crossover Switch
The Crossover Switch (

) toggles the LAN port
between crossover mode (
X
) and straight-through
mode (
II
).
If you are connecting the Router’s LAN Port
directly to a PC or an uplink port on a hub or
switch, choose the crossover (X) mode.
If you are connecting the Router’s LAN port to a
standard port on a hub or switch, choose the
straight-through (
II
) mode.
