3Com 510 manual WAN OfficeConnect Remote 520 and 530 only

1-10 CHAPTER 1: GETTING STARTED

COAX (10Base2 Coaxial Port) – The coaxial LAN port allows a 10Base2 Ethernet segment to be connected directly to the OfficeConnect Remote. If the unit is to be installed at the end of a cable run, then a 50 Ohm terminator must be fitted to the 10Base2 cable connector. This port can be used to connect to OfficeConnect hubs.

MDI/MDIX Switch Affects the operation of the 10BaseT LAN port. If you are connecting to a hub, leave the switch in the In position. If you are connecting to a single PC, set the switch to the Out position to implement the 10BaseT crossover that is required.

WAN (OfficeConnect Remote 520 and 530 only)

This port is used to provide connection to a WAN, via a private leased line. The port terminates with a

25-way D-type female connector. This port supports any of the CCITT data transmission standards; X.21/V.11 V.24/V.28 (RS232), and V.35/V.36 at data transfer rates up to 2 Mbps. Provided that connection cables that follow these standards are used, the OfficeConnect Remote automatically detects the type of interface that the port is required to support, and configure it accordingly.

Refer to Appendix B for information about the WAN interface cables required. Suitable cables are available from your 3Com reseller as spare parts, refer to Appendix B for required item part number

10BASET This RJ45 port is to the left of the ISDN socket when looking at the rear of the unit and is used to provide a connection to a 10BaseT LAN. This socket allows direct connection between the OfficeConnect Remote and a single piece of equipment, as opposed to multi-point LAN connections using 10Base2 cabling systems. The OfficeConnect Remote LAN port simulates the characteristics of a workstation port, which allows it to be directly connected to a LAN or network hub port as required.

If the LAN port is to be connected directly to a single PC or workstation, then you must implement the crossover by setting the MDI/MDIX switch to the out position. See “MDI/MDIX Switch” for more information.

ISDN This port is used to connect to the ISDN network. The port uses an RJ45 connection socket situated to the left of the 10BaseT LAN socket. A standard ISDN line wall socket is required to connect the ISDN cable to the ISDN port of the OfficeConnect Remote.
