FCC NOTICE

This device complies with Part 15 of the FCC rules. Operation is subject to the following

two conditions: (1) this device may not cause harmful interference, and (2) this device

must accept any interference received, including interference that may cause undesired

operation.

NOTE

: This equipment has been tested and found to comply with the limits for a Class A

digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide

reasonable protection against harmful interference when the equipment is operated in a

commercial environment. This equipment uses, generates, and can radiate radio frequency

energy and if not installed in accordance with the operator’s manual, may cause harmful

interference to radio communications. Operation of this equipment in a residential area is

likely to cause interference in which case the user will be required to correct the

interference at his own expense.

WARNING

: Changes or modiﬁcations made to this device which are not expressly

approved by the party responsible for compliance could void the user’s authority to

operate the equipment.

This equipment complies with FCC Rules Part 68. The FCC Registration Number and

SPECIAL REQUIREMENTS FOR CANADA

The Industry Canada Department’s label identiﬁes certiﬁed equipment. This certiﬁcation

means that the equipment meets certain telecommunications network protective,

operational and safety requirements. The Department does not guarantee the equipment

will operate to the user’s satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected

to the facilities of the local telecommunications company. The equipment must also be

installed using an acceptable method of connection. In some cases, the company’s inside

wiring associated with a single line individual service may be extended by means of a

certiﬁed connector assembly (telephone extension cord). The customer should be aware

that compliance with the above conditions may not prevent degradation of service in some

situations.

Repairs to certiﬁed equipment should be made by an authorized Canadian maintenance

facility designated by the supplier. Any repairs or alterations made by the user to this

equipment, or equipment malfunctions, may give the telecommunications company cause

to request the user to disconnect the equipment. For their own protection users should

ensure that the electrical ground connections of the power utility, telephone lines and

internal metallic water pipe system, if present, are connected together. This precaution

may be particularly important in rural areas.

CAUTION

: Users should not make installation connections themselves, but should

contact the appropriate electric inspection authority or electrician.

Load Number

The Load Number (LN) assigned to each terminal device denotes the percentage of the

total load to be connected to a telephone loop which is used by the device, to prevent

overloading. The termination on a loop can consist of any combination of devices subject

only to the requirement that the total of the LNs of all the devices does not exceed 100.

1.5 MICRO-CS OVERVIEW

The Cabletron Micro-CS is a Xylogics Remote Annex 2000 compatible,

multi-port communication server designed to reside in the MicroMMAC

series of stand-alone hubs. The Micro-CS integrates a communication

server with remote dial-in/dial out access, dial-up routing, and terminal

and communications access capabilities into the MicroMMAC.

1.5.1 Remote Network Access

The Micro-CS provides network support for: TCP/IP, Novell Netware,

and AppleTalk.

1.5.2 Dial-Up Routing

The Micro-CS provides dial-up routing support for UNIX and Novell

networks. Using a Micro-CS, Network Administrators can connect two or

more networks over a standard telephone line.

Chapter 1:

Introduction

1-4 Micro-CS Installation Guide

1.5.3 Terminal and Communications Access

The Micro-CS provides terminal and communications access to users on a

local area network. The Micro-CS can connect up to 7 asynchronous

serial devices to host computers on a LAN.

1.5.4 System Description

The Micro-CS is a powerful 32-bit device that comes with an Intel 80486

SXLC2 clock-doubled processor. The Micro-CS read-only memory

(ROM) contains ﬁrmware for performing power-up self-tests and loading

operational code. A non-volatile EEPROM stores the conﬁguration

parameters.

The ROM Monitor is an interactive command interpreter that accesses the

ROM’s functions. ROM Monitor commands are issued through a terminal

connected to the console port on the Micro-CS

.

Using the ROM Monitor

commands, you can:

•

Modify and display a set of EEPROM parameters.

•

Execute interactive diagnostic tests.

•

Receive information and statistics for the hardware conﬁguration and

the network.

•

Boot the Micro-CS manually.

The Micro-CS is a diskless device. It obtains operational code either over

the network from a host running Micro Annex Communication Software

Version 9.2.6 or above, another Micro-CS conﬁgured as a load server, or

from self-contained Flash Memory.

The Micro-CS has a watchdog timer that is reset by the software at

regular intervals. The watchdog timer reboots the Micro-CS in the

unlikely event of an internal software error. This feature allows the

Micro-CS to run for long periods of time without intervention.

A modem upgrade for the Micro-CS is available for added functionality.

It consists of a single daughter card, and can be user installed. The

upgrade kit can be purchased separately from Cabletron as part number

CSM-V.34-UGK.

Micro-CS Overview

LED indicators provide the user feedback on system activity. Each port

connector has an associated LED to indicate activity on the receive data

line. Several other LEDs indicate Network Activity, diagnostic failure and

other fault connections.

1.5.5 Micro-CS Front Panel

The Micro-CS (Figure 1-1) front panel contains the following:

•

4 System Indicators

•

5 Modem status indicators

•

1.5.8 SETUP Switch

The SETUP button allows you to change the operational mode of the

Micro-CS from Normal to Test. It also functions as a Reset button (see

Note below). The Micro-CS automatically powers up in normal mode. To

enter test mode, press the SETUP button within three seconds of

powering-up.

Additionally, a Setup signal is provided from the MicroMMAC

motherboard. When this signal is active, it will perform a cold start of the

Micro-CS.

1.5.9 Port Activity Indicators

The LED activity indicators associated with ports 1-7 blink to indicate

data either data transmitted to or received by that port. The “M” port

lights to indicate the modem is seeing activity. The 5 modem LED’s blink

to indicate the modem is sending or receiving data from the WAN

network.

Chapter 1: Introduction

1-8 Micro-CS Installation Guide

1.5.10 Console Port

The Micro-CS uses port 1 as a console port during SETUP. To access the

console port, press the Setup switch within 3 seconds of powering-up.

The console port provides access to the ROM Monitor commands when

the Micro-CS is in set up mode. After returning to normal mode, Port 1

functions as a serial port. Refer to Appendix B for console pinout

information.

1.5.11 Network Port

The Micro-CS can be connected to an Ethernet LAN either one of two

ways: through an RJ-45 connector to the MicroMMAC internal AUI, or

through an RJ-45 connector on the front panel between the network port

and a port on the MicroMMAC. The internal AUI is provided by the

Cabletron EPIM-3PS, provided with the Micro-CS. The Micro-CS

automatically sets up the connection, either internally to the

MicroMMAC, or externally to a 10BASE-T port. Refer to Appendix B for

port pinout information.

1.5.12 Modem Port

If your Micro-CS is equipped with the optional modem card, the punch

out on the faceplate should have been removed to expose the modem port.

This port supports a V.34 modem with an RJ-11 connector allowing

modem network access.

If your Micro-CS does not have the optional modem, then connecting to

the port is futile. The modem card can be purchased by contacting

Cabletron Customer Support at (603) 332-9400 and ordering part number

CSM-V.34-UGK.
