SonicWALL GX250 Front Panel
Three Fast Ethernet interfaces provide connectivity for either Ethernet and Fast Ethernet networks.
The Ethernet ports connect the SonicWALL to the LAN, DMZ, and WAN using category 5 twisted pair
cable with RJ-45 connectors. The standard NIC has two LEDs:
•
Link/Activity
The Link light is green when a twisted pair connection is made to another Ethernet device
(usually a switch or a hub) on the port. Note that the device connected to the SonicWALL must
support the standard link integrity test. The Link LED blinks, indicating Activity, when the
SonicWALL transmits or receives a packet through the Twisted Pair port onto the network.
• Network Speed
The Network Speed LED is not lit if the network speed is 10 Mbps, and the LED is green if the
network speed is 100 Mbps.
SonicWALL GX 650 Front Panel
Three Gigabit over Fiber or Copper ports provide connectivity for Gigabit networks. Before inserting
the cables into the network ports on the fiber optics card, remove the plug from the ports. The
1000Base-SX interface has the following LED lights:
•
Transmit (TX)
The TX light is lit when the network is transmitting data over the network connection.
• Receive (RX)
The RX light is lit when data is received over the network connection.
• Link
The Link LED indicates that the interface is connected to a valid link partner and is receiving
link pulses.
The 1000Base-T network interface has the following LEDs:
•
Link
The Link light is green when a network connection is made to another Ethernet device (usually
a hub) on the port.
• Activity
The Activity LED blinks, indicating Activity, when the SonicWALL transmits or receives a frame.
• Network Speed
The Network Speed light remains off if there is no connection or if a 10Mbps connection is
made. If a 100 Mbps connection is made, the LED is green. If a 1000 Mbps connection is
obtained, the LED is yellow.
• Reset Switch
Resets the SonicWALL GX250 or the SonicWALL GX 650 to its factory clean state. This may be
required if you forget the administrator password, or the SonicWALL firmware has become
corrupt.
