Power Green. The Power LED lights up green when the Router is
powered on.
Link/Act Green. The Link/Act LED serves two purposes. If the LED
is continuously lit, the Router is successfully connected to a
device through the corresponding RJ-45 port (1, 2, or 3). If
the LED flickers, then that port is sending or receiving data
to and from the network. When the Uplink port is in use, then
Port 3 will be lit.
Full/Col Green. The Full/Col LED also serves two purposes. If this
LED is continuously lit, the connection made through the
corresponding port is running in Full Duplex mode. If the
LED is flickering, the connection is experiencing collisions.
Infrequent collisions are normal.
If this LED flickers too often, there may be a problem with
your connection. See “Appendix A: Troubleshooting” if you
have problems.
100 Orange. The 100 LED lights up when a successful 100 Mbps
connection is made through the corresponding port. If this
LED does not light up, then your connection speed is
10 Mbps.
USB The USB LED lights up when the USB port is successfully
connected to a USB-ready PC or USB hub.
