1 I NTRODUCTION This chapter provides a brief intr oduction to the AccessBuilder 4000 system. Unpacking instructions are also pr ovided. General The AccessBuilder 4000 series family are RISC-based mul.
1-2 C HAPTER 1: I NTRODUCTION The AccessBuilder 4000 is designed for enterprise organizations having remote LAN access r equirements. It is well-suited for situations where up to sixteen analog phone .
System Description 1-3 Figure 1-1 AccessBuilder 4000 Configuration Options System Description The AccessBuilder 4000 series servers consists of hardwar e and software that pr ovides a cost-effective solution to your remote access networking needs. Both the Ethernet and T oken Ring versions offer the same high performance RISC-based engine.
1-4 C HAPTER 1: I NTRODUCTION Hardwar e Description The following sections describe the system hardwar e components. The AccessBuilder 4000 system consists of a chassis assembly which contains one of two available main processor boar ds, power supply , indicator lights, and two slots for I/O cards of your choice.
System Description 1-5 and unshielded twisted pair (UTP) media connections. Ring speeds of 4Mbps or 16Mbps can also be selected. A built-in RS-232 console port (DCE) is also provided on the main processor boar ds (pinout information is provided in Appendix A).
1-6 C HAPTER 1: I NTRODUCTION Power Switch and Receptacle. The AC power switch is marked according to international 1/0 convention; when the 1 side is pressed, the switch is on; when the 0 side is pressed, the switch is of f. The switch and power receptacle ar e accessible from the right rear of the chassis.
2 G ETTING S TARTED This section is designed to help you to quickly perform the installation of an AccessBuilder 4000 network remote access server . Once you have planned your installation and set up the hardwar e, you are then ready to install and launch the T ranscend AccessBuilder Manager (T ABM) configuration utility .
2-2 C HAPTER 2: G ETTING S TARTED Should any of these special circumstances apply to your situation, information about performing the software configuration using the command-line interface is provid.
Preparation 2-3 Configuration worksheets are provided in Appendix D as a convenient means of collecting and organizing this information. Modems/ISDN T As 1 Check to be sure the modems or terminal adapters you intend to use are on the built-in modem list (or check the modem list in the Release Notes).
2-4 C HAPTER 2: G ETTING S TARTED For ARA and non-AppleT alk users to share the same ports, the use of AppleT alk Remote Access version 2.0 or later is recommended. If, however , you plan to support ARA 1.0, you will need to determine which asynchronous serial ports to use, since these ports will be dedicated to ARA 1.
Unpacking the System 2-5 If you plan to use SNMP functions, such as trap reporting or r emote device management, you will also need to know the community names and IP addresses of the management station(s). Y ou may also wish to define the greeting message the remote users will see when they log onto the AccessBuilder.
2-6 C HAPTER 2: G ETTING S TARTED If the original carton was damaged in shipment, repack the system in a carton that provides equivalent pr otection before returning it to 3Com.
Hardware Installation 2-7 Har dwar e Installation The following is a step-by-step procedur e for performing the AccessBuilder 4000 hardwar e installation. Stand Alone Pick a suitable location for the AccessBuilder 4000. Either a desktop or similar level surface may be used.
2-8 C HAPTER 2: G ETTING S TARTED LAN Connection (Mandatory) This connection is requir ed in either Ether net or T oken Ring environments. Ethernet 1 Connect your Ethernet LAN to the appropriate interface connector for your media type (10BaseT , BNC, or AUI).
