Introduction

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 de vice that comes with an Intel 80486
SXLC2 clock-doubled processor. The Micro-CS read-only memory
(ROM) contains firmw are for performing power-up self-tests and loading
operational code. A non-volatile EEPROM stores the configuration
parameters.

The ROM Monitor is an interacti ve 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
commands, you can:

Using the ROM Monitor

•

Modify and display a set of EEPROM parameters.

•

Execute interactive diagnostic tests.

•

Receive information and statistics for the hardw are configuration and
the network.

•

Boot the Micro-CS manually.

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

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 e xternally to a 10B ASE-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 remo ved to e xpose 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

MICRO-CS INSTALLATION

2.1 GENERAL

The Micro-CS comes factory installed in the MicroMMAC as a
MicroCS-T-22ES, or MicroCS-LT-22ES, or can be ordered seperately as
an upgrade kit, part number MICRO-CST-UGK or MICRO-CSLT-UGK.
If you have the upgrade kit, please refer to Appendix E for installation
instructions.

Installation procedures for the MicroCS follow those of the Cabletron
Systems MicroMMAC series. For installation and Local Management
instructions related to the Ethernet networking functionality of the
MicroCS, please refer to the MicroMMAC documentation.

This chapter explains the connection of serial devices, attaching to the
console port, power up and testing, and software installation of your new
Micro-CS. Please read through all the material before powering up to gain
an understanding of how to set up the system.

2.2 CONSOLE PORT TERMINAL

In order to access the ROM Monitor and boot the Micro-CS for the first
time, the Micro-CS must be connected to a terminal. Connect the console
terminal to port 1. Set the terminal to 9600 baud, eight data bits, no parity ,
one stop bit, and XON/XOFF flow control. The ROM Monitor assumes
that this terminal is CR T-based and displays the backspace (BS) character
accordingly .

Appendix A describes the console port’s signal/pin allocations.

Micro-CS Installation Guide 2-1

Chapter 2: Micro-CS Installation

Press SETUP within 3 seconds of powering up to put the Micro-CS into
ROM Monitor mode. You can also reset the Micro-CS and enter the R OM
Monitor mode by pressing the SETUP switch for at least three seconds,
until the SETUP LED flashes indicating a reset. Release the switch and
all the port LEDs will turn on then off. Press the SETUP switch again
within 3 seconds after the PORT LEDs have turned off, and the SETUP
LED will be on indicating the Micro-CS is in setup mode. Once the
Micro-CS has successfully completed its start-up diagnostics, the ATTN
LED will turn on indicating ROM Monitor mode. Each subsequent
depression of the SETUP switch will toggle the Micro-CS SETUP LED
off and on. In order to return to Normal mode, the Micro-CS must be
re-booted.

NOTE

state.

2.3 SERIAL DEVICES

The Micro-CS provides 7 total port connections. Port 1 is used for the
initial console connection, but reverts to an Annex serial port after
bootup.

To connect to serial devices, simply insert one end of the RJ45 cable into
one of the seven numbered ports on the front of the Micro-CS. Attach the
opposite end of the serial port cable to your serial device.

The Micro-CS serial cables conform to both the RS232 and RS423
specifications regarding the data signals (TxD, RxD). However, it is
possible to exceed the specifications’ cable limits given high quality
cables that are run in an electrically quiet environment, or a DTE
connecting device that uses RS423 drivers. Refer to the DTE manual for
information regarding the serial drivers supported. Cabletron only
guarantees operation with cables that conform to the appropriate
specification. Table 2-4 lists the maximum recommended cable lengths
when connecting to an RS232C compliant device.

The Micro-CS can incur damage if the cables conduct

Next, the Micro-CS runs diagnostic tests causing the NET indicator to
flash. If the diagnostics complete successfully, the STATUS and
ATTN indicators light, and the ROM Monitor prompt (

monitor::)

appears on the terminal. The tests complete in approximately one
minute. If the prompt appears, go to Step 4.

If the STAT and ATTN indicators do not light within one minute or if
the indicators flash, a hardware failure has occurred. Contact
Cabletron Technical Support.

4. Verify the Micro-CS hardware configuration.

At the monitor prompt on the console, type config and press the
Return key. The following is a typical configuration display:

monitor:: config

5. Record the Ethernet address of the Micro-CS for future reference.

At the monitor prompt, type addr -d and press the Return key. The
display looks like this:

monitor:: addr -d
Ethernet address (hex): 00-80-2D-00-18-B6
Internet address: <uninitialized>
Subnet mask: 255.255.0.0
Broadcast address: 0.0.0.0
Preferred Load Host address: <any host>

Preferred Dump Host address: 0.0.0.0

Load/Dump Gateway address: <uninitialized>
Type of IP packet encapsulation: <ethernet>
Load Broadcast: Y

You are prompted for the gateway address only if the internet

NOTE

address differs from the preferred load host address based on
the subnet mask. If these addresses are the same, the
Micro-CS assumes there is no gateway.

6. Perform the “net” test to verify your network connectivity.

Connect the Micro-CS to the Ethernet network either through the
internal AUI, or by connecting a jumper cable from the Ethernet port
on the Micro-CS to a MicroMMAC port. At the monitor:: prompt,
type “net”.

If the unit passes the test, the console displays “Passed”. If it fails, an
error message is displayed.

7. “Ping” the software load host, as well as the IP address of the

MicroMMAC. This will test the connectivity of the Micro-CS to a
remote device.

At the monitor prompt, type “ping” and then specify the IP address of
the remote device. Specify the number of bytes per packet, and the
number of packets to be sent. The ping command display looks like
this:

monitor:: ping 134.141.72.165
PING 134.141.72.165: 64 data bytes

2.5 AUTO-INITIALIZING THE ROMS

The Micro-CS supports the BOOTP and RARP protocols. The ROMs use
these protocols to obtain boot information without requiring any manual
setup on the Micro-CS.

• BOOTP is a bootstrap protocol that allows a diskless client to

determine its Internet address, the Internet address of the server, and
the name of the file to be loaded into memory.

• RARP (Reverse Address Resolution Protocol) maps a hardware

address into an Internet address.

The ROMs invoke this system of acquiring boot information when a boot
is initiated and the Micro-CS’s Internet Address is not initialized. Under
this condition the Micro-CS first tries to get boot information via BOOTP;
if BOOTP fails, it tries to get boot information via RARP. If neither
protocol is successful, the Micro-CS either prompts the user for the
Internet address (if in SETUP mode) or it lights the ATTN LED to
indicate the Internet address is not set (if in Normal mode).

2.5.1 Retrieving Boot Information Using BOOTP

For a successful BOOTP retrieval a bootpd must be running on a host on
the same network as the Micro-CS and must have the appropriate
information in the bootptab file. The Micro-CS’s BOOTP
implementation adheres to rfc951, rfc1048, and rfc1084 specifications.
Below is a sample bootptab file entry used to initialize the Micro-CS
named terminator.
