Advanced Reference Guide

Introduction

The master hub (and connected stack) can be managed through a PC or modem connection to the hub’s serial port, or with SNMP-based network management software such as AccView/Open. Using the configuration program, you can perform the following tasks:

•Enable/disable any port

•Assign backup ports

•Set threshold values

•Configure SNMP parameters

•Display system information or statistics

•Download system firmware

•Restart the system

Making the Connections Required for System Configuration

The diskette included with the EtherHub-16mi+contains a menu-driven configuration program. To use this program, make a direct PC or modem connection to the serial port on the master hub in the stack.

This section describes how to access the menu-driven configuration program via:

•Onsite connection

A workstation connected to the serial port on the hub.

•Modem connection

A workstation connected to the serial port of a remote hub via modems.

•In-band connection

It also describes how to access the embedded SNMP agent over the network using AccView/Open or other third-party network management software.

Onsite Connection

Attach a PC to the serial port on the master hub. Use the null-modem cable (and DB9 / RJ-45 converters) provided with this package, or use a null modem connection that complies with the wiring assignments shown in the back of this guide.

Modem Connection

Configure the Hub Site: Connect the master hub's DB9 serial port to the modem's serial port using standard cabling. 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 at the hub's site, because the hub will automatically configure it to auto-answer mode.

Configure the Remote Site: At the remote site, connect the PC's COM port (COM 1~4) to the modem's serial port.

In-Band Network Connection

The EtherHub 1500 sytem can also be managed from a computer using network management software such as AccView/Open. However, prior to accessing the hub, you must first configure it with a valid IP address, subnet mask, and default gateway using an out-of-band connection.
