SonicWALL PRO 200 Installation Manual page 75

• Test
Lights up when the SonicWALL is powered up and performing diagnostic tests for
proper operation. These tests take up to 5 minutes. If the Test LED remains lit after
this time, the firmware is corrupt and must be reinstalled.
• Serial Port
DB-9 RS-232 Serial port for a modem or null-modem cable to support Command Line
Interface Management.
There are three network interfaces on the GX Models from left to right:
• WAN
• LAN
• DMZ
The GX 250 includes two Fast Ethernet network interfaces.The GX 650 includes either Fast
Ethernet or 1000Base-SX over Fiber network interfaces. A fourth slot for upgrades is available
on the GX 250.
Two types of network cards are available in the GX series:
• Fast Ethernet (10/100Base-T)
• Gigabit over Fiber (1000Base-SX)
GX 250 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. There is an additional slot available for
upgrading the appliance. 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.
• GX650 Front Panel
Three Gigabit over Fiber 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.
