CHAPTER 2. HARDWARE DESCRIPTION 102.5.2 Ethernet WANArctic 3G has one physical port for Ethernet WAN. Specifications are shown in table 2.4.ConnectorNumber of ports 1Speed 10Base-T, 100Base-TXDuplexHalf and FullAuto-negotiationYesRecommended cabling Cat5 or betterTable 2.4: Ethernet WAN specificationsIf Ethernet WAN interface is directly connected to computer, crossover cable must be used. Ethernet WANinterface does not support automatic MDI/MDIX detection.2.5.3 Ethernet LANArctic 3G has three physical ports for Ethernet LAN. These ports are connected to a common switch. Specificationsare shown in table 2.5.ConnectorNumber of ports 3Speed 10Base-T, 100Base-TXDuplexHalf and FullAuto-negotiationYesRecommended cabling Cat5 or betterTable 2.5: Ethernet LAN specificationsIf Ethernet LAN interface is directly connected to computer, both crossover and straight cables can be used.Ethernet LAN interface supports automatic MDI/MDIX detection.2.6 Serial portsArctic 3G has two application serial ports and one serial console port.Serial port 1 is configurable to multiple serial formats (RS-232/422/485), while serial port 2 supports onlyRS-232 data mode.Serial port connectors are 9-pin D-sub (male) connectors. Serial ports enact as DTE devices.2.6.1 Serial console portSerial console connector is located in Arctic 3G front panel (see figure 2.1). Connector type is RJ45.
