42 Appendix A Technical specificationsNN46110-313 02.01System portsThe VPN Router 1010/1050/1100 system board provides the following interfaces:• 10/100BASE-TX Ethernet LAN ports• Serial portThis section provides information about the 10/100BASE-TX Ethernet LAN portsand the serial port on the system board.10/100BASE-TX Ethernet LAN portsThe VPN Router 1010, 1050, and 1100 have two internal LANs built in:• LAN 0 is the private LAN and also the LAN to use for Web management.— The LAN 0 connector on the front of the VPN Router 1010 is an EthernetMDI configuration and requires a crossover cable (included with yourshipment).— The LAN 0 connectors on the front of the VPN Router 1050 and 1100 arean Ethernet medium dependent interface crossover (MDI-X)configuration. These ports support the Auto-MDI-X feature, so eitherstraight-through or crossover cables can be used.• LAN 1 defaults to a public LAN. The software refers to the LAN 1 port as slot1, interface 1.The LAN 1 connector on the front of the VPN Router 1010, 1050, and 1100 is anEthernet MDI configuration and requires an RJ-45 straight-through cable.Depending on whether you use the interface for 10BASE-T or 100BASE-TXoperation, select cables for the interfaces as follows:• 100BASE-TX connections require Category 5 twisted-pair wire. The100BASE-TX specification supports 100 Mb/s transmission over two pairs ofCategory 5 twisted-pair Ethernet wiring: one pair each for transmit andreceive operations.Nortel recommends a maximum length of 100 meters for the cable segmentbetween a 100BASE-TX repeater and a workstation (due to signal timingrequirements). This wiring scheme complies with the EIA 568 wiringstandard.
