Remote Connection

If you want to use a remote PC to configure either of the Fast EtherHub-12mi models via modem connections, at the remote site make sure the modem’s baud rate is 9600 and that the AT command set is supported.

Connect your modem and PC at the remote site. Dial into the management agent, and remotely configure the hub using the on- board configuration program; or directly attach to the network via a SLIP connection and perform configuration or management functions using in-band network management software.

Configuring the Fast EtherHub Site

Connect the hub’s DB9 serial port to the modem’s serial port using standard serial cabling. (Refer to Appendix B for pin assignments). For most modems, which use a 25-pin port, you will have to provide an RS232 cable with a 9-pin connector on one end and a 25-pin connection on the other end. You do not have to set the modem communication parameters at the hub’s site, because the hub will automatically configure it to auto- answer mode. Just set it to force Data Set Ready (DSR) signals.

Configuring the Remote Site

At the remote site, connect the PC’s COM port (COM 1~4) to the modem’s serial port. Set terminal emulation type to VT100, specify the port used by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, and 9600 bps. Also be sure you set the flow control to “none.”

Remote Configuration Methods

Remote On-Board- If you establish a remote connection as described in the previous section, you can use the on-board management functions on the Fast EtherHub-12mi via a terminal emulation program. See the section on

later in this chapter for

more information. However, note that the on-board configuration functions only provide access to the hub’s private MIB. To access the full range of SNMP management functions, you must use optional network management software (e.g., AccView/Open).
