1DECserver 900GM Installation

Introduction

TheDECserver900GMisanetworkaccessserverthatsupportsupto16fullmodem

controlports, or32 eight–wirepartialmodemcontrolports. TheDECserver 900GMx

is identical to the DECserver 900GM, except that it supports up to 8 full modem

controlports,or16eight–wirepartialmodemcontrol ports.Theportsmaybeusedto

connect asynchronous devices including terminals, printers, modems, or PCs to an

Ethernet local area network (LAN). Both systems operate in a DEChub 900

Multiswitch or as a standalone access server.

Except where noted, all references to the DECserver 900GM also apply to the

DECserver 900GMx.

NOTE: Inthismanual,thetermEthernetisDigital’stermforitsproductcompatibility

with the ISO 8802-3/ANSI/IEEE 802.3 standards and the Ethernet

standards for Carrier Sense Multiple Access with Collision detection

(CSMA/CD) local area networks (LANs).

To give your workgroup LAN media flexibility and connectivity, the module can be

configured into a DEChub 900 MultiSwitch (also referred to in this manual as the

DEChub 900). One or more DECserver 900GM modules can be installed into the

DEChub 900 (a maximum of 8 DECservers can be present; however, to connect to

the network, there must also be at least one repeater or one bridge in the

configuration).Themodulecanalsoserveasastandaloneunitwhenconfiguredwith

a DEChub ONE docking station (see the

DEChub ONE

installation

manual).

When the module is installed into a DEChub 900, the module’s hot-swap capability

allows you to install or remove the module without turning off power to the DEChub

900.

The DECserver 900GM is configured with four 68-pin D-connectors (two for the

DECserver900GMx),andprovidesfullorlimitedmodemcontrol.Eachportsupports

16 baud rates from 75 baud to 115.2 Kbaud. The DECserver 900GM includes 4

megabytes (MB) of standard memory, and can be expanded to 8 MB.

1Throughout this manual, the term DEChub ONE refers to the DEChub ONE or the

DEChub ONE-MX docking station unless otherwise specified.

1) Power LED — Lights when the module has

power.

2) Module OK LED — Lights when the

module passes self-test.

3) Network OK LED — Lights when the module

has an active network connection.

4) Network Activity LED — Indicates network

traffic level.

5) Seven-Segment Display — Provides error and

status information. For more information, see the

section titled Problem Solving Using the Seven Seg-

ment Display.

6) Flash RAM Slot — Provides an opening in which to

insert the Flash RAM card.

7) Address Label — Contains the module’s 48-bit

Ethernet Hardware Address.

8) Reset Switch — Resets the module to factory de-

faults.Toreset: whileturningonthepower,pressand

hold the reset switch until the Module OK LED

flashes, or if the DECserver 900GM is in operational

mode (the seven-segment display shows the “race

track” pattern), hold the switch for 10 seconds. The

module reboots with factory defaults.

9) Bulk Connectors — Four 68-pin connectors, each

providing 4 full modem control ports or 8 partial mo-

dem control ports. When using all four connectors,
