Power LED (Illuminated Logo)
White
The 3Com logo serves as power OK indicator. This LED will light if the
router is receiving power from the power adapter. If it is not lit check the
power adapter connections. Refer to
Chapter 6 Troubleshooting
.
2
Alert LED
Amber
Fast flash during self test. If self test fails the LED will remain on.
Fast flash during software upgrade.
Fast flash for software reset to the factory defaults.
Fast flash for hardware reset to the factory defaults.
The LED is on for 2 seconds when the firewall detects a hacker attack.
3
ADSL Sync
Blue
LED on indicates the Internet connection is on. This LED flashes during
configuration at power up.
4
ADSL Data
Blue
Fast flash means transmitting/receiving data.
Slow flash means ADSL connection is down.
5
Wireless LAN (WLAN) Status LED
Blue
If the LED is on it indicates that wireless networking is enabled. If the LED
is flashing, the link is OK and data is being transmitted or received. If the
LED is off, the Wireless LAN has been disabled in the Router, or there is a
problem. Refer to
Chapter 6 Troubleshooting
.
6
LAN Status LEDs (4 indicators)
Blue
If the LED is on, the link between the port and the next piece of network
equipment is OK. If the LED is flashing, the link is OK and data is being
transmitted or received. If the LED is off, nothing is connected, or the
connected device is switched off, or there is a problem with the
connection (refer to
Chapter 6 Troubleshooting
). The port will
automatically adjust to the correct speed and duplex.

WPS LED
Blue
WiFi Protected Setup (WPS) is a standard for easy and secure
establishment of a wireless network, allowing wireless clients to connect
securely to routers and access points. The WPS LED shows the status of
the WPS function. It has a number of modes to help monitor the status of
clients connecting to the Router using the WPS protocol. The status is
shown by three different flashing rates: slow, medium and quick and
when light constantly.
Note: The WPS function will be enabled for 2 minutes once WPS is
enabled either by pressing the button or by starting the PIN mode via the
web interface. This time will end before 2 minutes if a client has
successfully connected. Only one client should be connected to the
Router using WPS at any one time. Attempting to connect two or more
clients at once may result in connection failures.
When the WPS button is pressed, or WPS is initiated using the PIN
method in the web interface, the WPS LED will flash at a medium rate for
up to 2 minutes to indicate that a WPS connection can be made. When a
connection attempt is underway, the LED will flash slowly.
If the connection has been successful, the WPS LED will remain
illuminated for 5 minutes. If the connection attempt has failed, the WPS
LED will flash rapidly for 5 minutes. You can re-try the connection by
pressing the WPS button, when the connection process will re-start.
If you want to add a further client to the Router, you do not need to wait
for the 5 minute period to end. You can press the WPS button (or use the
PIN method via the web interface) as soon as the first client is successfully
connected.

Ethernet Ports (4 ports)
Using suitable RJ-45 cables, you can connect your Router to a computer,
or to any other piece of equipment that has an Ethernet connection (for
example, a hub or a switch). These ports have an automatic MDI/MDIX
feature, which means either straight-through or a crossover cable can be
used.
