Introduction

This chapter provides steps for solving problems if the MiniArray
thoroughly tested at the factory before it was shipped. If you are unable to make a successful
connection, it is possible that the MiniArray
source of your problem lies elsewhere. As with any microcomputer product, start with simple
hardware and software problems, and then work toward more complex problems (i.e.,
operating system and/or applications).

Troubleshooting

The following troubleshooting process addresses some of the typical problems and with
some basic solutions. If a problem arises while you are in an application, refer to the
software documentation.

• No Video

• Verify that power is ON, and LED in power switch is lit.

• Verify that SBC and any other adapter boards are connected properly.
NOTE: Make sure to turn power OFF to reconnect boards.

• Verify that monitor is turned ON, and verify that power is connected to
monitor and video cable is connected to video connector on SBC.

• Verify that two or four 72-pin, memory SIMMs are connected properly on the
SBC. The SIMMs they must be the same brand, size and speed.

• If some device other than a modem is connected to COM 1, verify that the
DCD jumper is not installed.

• Remove all connectors from the SBC and adapter boards, except the video
connector, and then power ON the MiniArray

III

. If MiniArray
then there is a problem with one of the cables or one of the peripherals. Try
each cable, one at a time, to isolate the bad cable or peripheral.

• Verify that fan in front of card cage is running. If power is on and fan is
stopped, check to be sure power connectors from power supply to midplane
are fully connected.

• If problem persists, contact MultiTech's Technical Support Department, refer
to Chapter 6 of this manual.

• SBC does not boot correctly or hangs after video appears

• Run BIOS Setup Utility to verify correct configuration for system and drives
(press <DEL> as system boots).

• If boot PROM is used, verify that network and adapter card are configured
properly to see the network.

34 MA6

• Verify that SBC and adapter boards are seated properly in ISA slot. NOTE:
Make sure to turn power off to reconnect boards.

• Hard drive or floppy drive cables are not connected properly or parameters
are not set properly in setup.

• Verify that enough memory is installed to load the intended applications.

• Verify that two or four 72-pin SIMMs are seated properly on the SBC. The
SIMMs must be the same brand, size and speed.

• If some device other than a modem is connected to COM1, verify that the
DCD jumper is not installed.

• Remove all adapter cards. If system boots there is a conflict with an adapter
card.

• If problem persists, contact MultiTech's Technical Support Department, refer
to Chapter 6 of this manual.

• COM1, COM2 or LPT1 port does not respond correctly

• If some device other than a modem is connected to COM1, verify that the
DCD jumper is not installed.

• Try COM2, if it also fails, check Setup configuration and verify that the ports
are enabled.

• Check if any adapter boards are conflicting with ports. If ports are used by
an expansion card, then on board ports must be turned off in Setup.

• Check that cables are connected properly and peripherals are powered ON
and configured properly.

• If problem persists, contact MultiTech's Technical Support Department, refer
to Chapter 6 of this manual.

• Keyboard does not respond to key strokes

• Connect keyboard cable to the left round connector on SBC.

• If cable converter is used to connect a large 5-pin DIN to a small 6-PIN PS/2
DIN, this converter could be bad or of the wrong type.

• Verify that the keyboard works on a different system.

• If problem persists, contact MultiTech's Technical Support Department, refer
to Chapter 6 of this manual.

• Invalid Time, Date or Setup

• Battery is failing.

• Last system boot was incomplete. Verify in Setup that configuration is
correct and reboot system.

• If problem persists, contact MultiTech's Technical Support Department, refer
to Chapter 6 of this manual.

Radius Software: “Clients” and “Users” Files

After installing the Radius software, the administrator must customize the Clients file and the
Users file for use in their specific network system. These files can be found in C:\Program
Files\MultiTech Systems\Radius Server. The Clients file and the Users file can both be opened in
Notepad or Wordpad text-processor application programs.

In the Clients file, the administrator specifies the IP address of the RAS Server and the shared
secret known to both the CommPlete 4000 RAS server and to the password authentication server.
Entries in the Clients file must be in this form:

<IP address of client> <blank or tab(s)> <shared secret> <new line>

The IP addresses should be in dotted notation only. Names are not permitted.

For Windows NT only. In the Users file, the administrator lists network users by name and specifies
authentication/password parameters. The "users" file can include another file which contains a list of
users. The syntax is as follows:

$include <full path to the users file>.

When this command is employed under Windows NT, the authentication server can use the same user
database as the host server.

The first line in each user entry contains the following information:

<User name> <Tab> <Check List>

The <User name> field must start from the first column. The <Check List> field can have the
following info :

(i). Auth-Type. This field specifies whether the authentication is done locally or by the

system (for WindowsNT only). Values: Local or System.

(ii). Password = <The password of the particular user>

Indicates that PAP is the authentication protocol.

(iii). CHAP-Password = <The password of the particular user>

Indicates that CHAP protocol is the authentication protocol.

(iv). Prefix and Suffix.

The "users" file can also have DEFAULT entries which have the user name as DEFAULT. These
entries match on all users.

Concerning the notation, Fall-Through = 1 in the reply list,
=> the user entries which follow this user entry are also examined.

For NT Domain Authentication, the check list in the user entries can contain the attribute "Domain­name," to indicate the domain in which the user is authenticated. For NT Domain Auth to work
properly, the person who has logged on should be given the rights "Act as part of the operating
System" and "Log On as Batch Job".

Appendix E: MultiManager
Introduction

Multi-Tech MultiManager is a password-protected Windows 95/98/NT program for SNMP­based administration of RASExpress servers. It can be run from a network client PC or from
a dial-in remote-node or remote-control PC. Using MultiManager you can:

• maintain a map of your servers.

• monitor your servers.

• configure your servers.

• manage your communication lines and servers.

• display numeric statistics.

• graph online and offline statistics.

• display selected traps.

Installation

We recommend that you install MultiManager on a workstation that is on the same network
as a RASExpress server; however MultiManager can be run from any PC that has Internet
access. The workstation must be running Windows 95 or above, or Windows NT 4.0 or
above. To install MultiManager:

1. Insert MultiManager Disk 1 into drive A of the management PC. Do not use the

RASExpress server computer.

2. In Windows Explorer, open drive A and double-click on Setup.exe.

3. Follow the directions in the MultiManager Setup wizard.

Starting MultiManager

1. To start MultiManager, click Start, point to Programs, point to MultiManager, and then

click MultiManager. Alternately, create a shortcut on the desktop and then double-click it.

2. When MultiManager opens, log in using a valid user name and password. Initially no

password is required, but if you opt to use one, you can set it by clicking Change Password
in the Edit menu. Note that the password is case-sensitive.

To configure a server, you must log in as supervisor.

3. If you are starting MultiManager for the first time, click Edit, then click Auto Detect to

map the servers on your network. Valid servers appear in the Auto Detect dialog box, the
device tree, and the network map.

4. Select a server by clicking it in either the device tree or the network map. When you select a

server, the toolbar buttons become active.

Main Window

The main window is the control center for configuring and managing your RASExpress
servers.

Title Bar

The title bar shows the IP address of the management workstation and the name and path of
the active map file.

Menu Bar

The menu bar contains menus for controlling MultiManager itself, for configuring and
managing your servers, for displaying statistics both numerically and graphically, and for
editing network maps. Most menu commands can be accessed through the toolbars; except
for those selecting the online and offline statistical graphs.

Toolbars

Below the title bar and menu bar are four toolbars, which can be resized, turned on and off,
and dragged and docked anywhere. From top to bottom:

• The Configuration toolbar is used to configure a RASExpress server.

• The Statistics toolbar is used to display throughput and other statistics collected since

the last reboot of the server.

• The Management toolbar is used to save configuration changes, reboot the server,

monitor connections, reset lines, set and display traps, and otherwise manage an
active server.

• The Draw toolbar is used to create and edit network maps of your servers.

Device Tree

The device tree, in the pane on the left, displays RASExpress servers and groups in an
Explorer-like tree. The manager is at the root of the tree. As in Explorer, you can expand or
contract branches by clicking + and – boxes. Just click any server in the tree to select it for
configuration or management. If no servers appear in the device tree when you open
MultiManager, you can cause MultiManager to look for them by selecting Auto Detect from
the Edit menu.

Network Map

The network map is in the pane on the right. Here you can define and select RASExpress
servers, and edit their device attributes by double-clicking their icons. Using the Draw
toolbar, you can show relationships among your servers, groups, and LAN and WAN links in
a graphic map of your network, which can then be saved to disk.

Status Bar

The status bar displays messages about the status of MultiManager and your SCROLL LOCK,
NUM LOCK, and CAPS LOCK keys, and displays the date and time.
