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.

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.

Micro-CS Installation Guide 2-5

Chapter 2: Micro-CS Installation

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.

2-6 Micro-CS Installation Guide

Auto-Initializing the ROMs

microcs default:\
:sm=255.255.255.0:gw=132.245.22.66:\
:hn:vm=auto:to=-18000:

terminator:\
:ht=1:ha=00802d004879:ip=132.245.22.6

:tc=microcsdefault:

In the previous example:

• sm is the subnet mask;

• gw is the load/ dump gateway address; ht is host type (1=Ethernet);

• ip is the Micro-CS’s Internet Address; ha is the Micro-CS’s hardware

address (Ethernet Address); and

• vm is the Vendor Magic Cookie.

When the Micro-CS receives a BOOTP response with the sm, gw, and ip
set, it sets the respective parameters: subnet_mask,
load_dump_gateway, and inet_addr. The Vendor Magic Cookie must
be set to auto. This indicates that bootpd should respond to the client
(Micro-CS in this case) with whatever format the client requests; the
Micro-CS (client) always requests in the decimal dot notation format
(99.130.83.99). The bootpd adds the address of the host on which it is
running as the Server Address in the bootp response message. The ROMs
use the Server Address as the preferred load host and store it in the
pref_load_addr parameter.

The bootpd must be running on the Micro-CS’s preferred load

NOTE

host.

2.5.2 Retrieving Boot Information Using RARP

If the Micro-CS does not receive a successful BOOTP response it uses
RARP to get the boot information. For a successful RARP retrieval,
TCP/IP must be running on a host that is on the same network as the
Micro-CS and the host’s ARP table must be initialized with the
Micro-CS’s Internet and Ethernet addresses (see the arp man page,
arp -s).

Micro-CS Installation Guide 2-7

Chapter 2: Micro-CS Installation

The only boot information that RARP provides is the Micro-CS’ s Internet
address. The ROMs save this information in the inet_addr parameter.
The ROMs use default information for the subnet mask and preferred
load host. This means the ROMs will broadcast their request.

The host serving the Micro-CS its boot information must be running on
the same network as the Micro-CS because the Micro-CS only broadcasts
BOOTP and RARP queries.

2.6 SOFTWARE INSTALLATION PROCEDURES

The Micro-CS’s operational image can be installed from a UNIX host on
a network. To do this, the operational code must first be loaded on the
UNIX host. The Micro-CS may also be booted from software loaded on a
another Micro-CS or from Flash memory (see Chapter 3). When loading
the Micro-CS software for the first time, use the ROM Monitor
commands. At the monitor prompt:

1. Execute the erase command to clear the EEPROM. (See the erase

command in Chapter 3.)

2. Execute the addr command to:

Enter the Micro-CS’s Internet address.

Modify any other parameters that the Micro-CS may require for the
initial boot, i.e., the preferred load host’s Internet address and the
subnet mask. (See the addr command in Chapter 3.)

3. If you are booting the Micro-CS using a Serial Line Internet Protocol

(SLIP) network interface, you must:

2-8 Micro-CS Installation Guide

Software Installation Procedures

Use the slip command to modify the port parameters for the SLIP
network interface (see the slip command in Chapter 3).

Use the sequence command to list the SLIP network interface in the
load/dump interface list (see the sequence command in Chapter 3).

4. Execute the boot command (see the boot command in Chapter 3).

After successful execution of the boot command, your Micro-CS should
display the Annex prompt. If the Micro-CS was booted from the monitor
mode, the SETUP button should be depressed once to turn off the SETUP
LED.

CHAPTER 3

ROM MONITOR COMMANDS

3.1 GENERAL

This chapter describes the ROM Monitor commands. These commands
are accessed through a terminal connected to port 1 when the Micro-CS is
in SETUP mode. Pressing the SETUP switch within 3 seconds of
powering up puts the Micro-CS into Set Up mode.

The ROM Monitor commands allow you to set a number of EEPROM
parameters. Some of these parameters, like the unit’ s Internet address, are
required for booting the Micro-CS; some parameters, like the broadcast
address, are required if the network configuration differs from the
supplied defaults. Table 3-1 lists the ROM Monitor commands.

Other parameters, although not required, are recommended for the
Micro-CS’s initial boot. Setting these parameters rather than using the
assigned defaults minimizes errors during the initial boot. For example,
setting the parameter that defines the preferred load host enables the
Micro-CS to load by requesting assistance from a specific host rather than
by broadcasting that request to all hosts on the Ethernet.

You can define the same parameters using the Network Administrator
(na) program as you can using the ROM Monitor. ROM Monitor
commands generally provide data about current EEPROM parameters.
When appropriate, they also display a prompt that allows the operator to
change those parameters. Default or current values for parameters are
displayed in brackets. For example:

Enter broadcast address [132.245.6.255]:

At the prompt enter a different value or press the Return key <cr> to
leave the displayed value unchanged.

You can use unique abbreviations for all R OM Monitor commands except
erase. For example, enter boot as bo, and enter net as n. If you enter an
abbreviation that is not unique enough, an error message is displayed on
the console terminal.

Commands

3.2 COMMANDS

Following is an explanation of each of the ROM monitor commands,
syntax and other usage information.

3.2.1 addr

The addr command displays and sets several Micro-CS operating
parameters (EEPROM values) relevant to IP network addressing:

• Internet address.

• Subnet mask.

• Broadcast address.

• Preferred Load Host address.

• Preferred Dump Host address.

• Load/Dump Gateway address.

• Type of IP Packet encapsulation.

• Load Broadcast

The addr -d command also displays the unit’s ROM-resident Ethernet
address in hexadecimal notation (see the CSMIM/MicroCS
Administrator’s Guide for UNIX). The command syntax is:

addr [–d]
If you enter the addr command without the –d argument, the console

prompts you for each Internet address. Enter Internet addresses using the
standard decimal dot (.) notation.

The addr –d command displays the Micro-CS’s Ethernet address, IP
address, subnet mask, broadcast address, preferred load host address,
preferred dump host address, load/dump gateway address, IP
encapsulation type, and Load Broadcast. The addr -d command cannot
be used to make changes to any of the displayed parameters.

3-4 Micro-CS Installation Guide

Commands

The Micro-CS must have an Internet (IP) address in its memory before it
can load its operational image across the Ethernet via the IP protocol.
Therefore, you must enter the IP address before booting the Micro-CS
from a UNIX load host. If you do not define an IP address for the
Micro-CS, it will attempt to learn the address using BOOTP or RARP. If
you do not define a subnet mask, the Micro-CS uses the generic mask for
the specified IP address.

The Micro-CS tries to boot from a preferred UNIX load host. If you do
not define a preferred load host, the Micro-CS broadcasts its load request
on the subnet and loads software from the first host that responds.

If the part of the IP address containing the network address differs from
the preferred load or dump host, that host must be reached through a
gateway. The addr command prompts you for this gateway’s IP address.

The Micro-CS uses the broadcast address parameter when loading a file.
If this parameter contains a specific address (for example,

132.245.6.255), the Micro-CS uses only that address for broadcast. If the
value is all zeroes (0.0.0.0), the ROM Monitor tries various combinations
of broadcast addresses and subnet or network broadcasts. The Micro-CS
broadcasts its request three times for each possible combination of
broadcast addresses.

You can specify the IP encapsulation type as either ethernet for Ethernet,
or ieee802 for IEEE 802.2/802.3. The default IP encapsulation is
ethernet. Many systems have hardware Ethernet interfaces that are IEEE

802.3 compliant, but very few actually do 802.3 IP packet encapsulation.

Do not change this parameter unless you know absolutely that

NOTE

your Ethernet does 802.2/802.3 IP packet encapsulation. An
incorrect IP encapsulation type prevents your Micro-CS from
booting.

Micro-CS Installation Guide 3-5

Chapter 3: ROM Monitor Commands

3.2.2 boot

The boot command requests the loading of appropriate Micro-CS
operating software from the preferred load host. The command syntax is:

boot [–lv | filename]

The boot –l command is supported only if the self-boot option

NOTE

(Flash) is installed.
Typing the letter q or CONTROL-C interrupts the boot.
If you try to boot with a non-existent image file name, the

Micro-CS will hang as it searches for the image. You must

press the RESET button to recover.
A successful boot disables the Console and the ROM monitor.

The boot command accepts a file name for the Micro-CS’s image. If the
file name is not specified, boot displays the default file name and prompts
for one. If you do not provide a file name, or have not defined one for the
Micro-CS, boot requests the default file oper.56.enet. You can also enter
a file name using the image command.

The Micro-CS boots from the defined preferred load host (UNIX/IP,
Novell/IPX, or VAX VMS/MOP). If the preferred load host is not def ined
or does not respond, the Micro-CS broadcasts on the Ethernet and loads
from the first host that responds.

To initiate loading, the Micro-CS sends a load request message to the
selected host. After receiving a response, the Micro-CS loads its
operational code to RAM memory. When loading is complete, it transfers
control to the newly-loaded program. The Micro-CS displays a symbol on
the console for each data block received during the boot.

When the Micro-CS begins to boot, it displays the load server host’s IP
address. If the unit does not boot successfully after several attempts, it
displays a boot attempt failed message; if the unit has opened the boot file
and an error occurs during the boot process, it displays a boot error report
on the console and returns to the ROM Monitor. The boot error report can
help determine the cause of the boot failure.

3-6 Micro-CS Installation Guide

Commands

During a boot, the console may display four possible status symbols: “.”
indicates received data blocks, “?” indicates unanswered requests, “*”
indicates transmission errors, and “! ~XXXX~” is a status word from the
Ethernet chip on the Micro-CS indicating a gross problem with the
Ethernet connection (if this symbol appears in your boot command
display, contact technical support).

The status word “! ~XXXX~”, where XXXX are four hexadecimal digits,
decodes as follows:

8000 = Command complete
4000 = Chip is busy
2000 = Command completed without error
1000 = Command aborted by an abort command
800 = Late collision detected
400 = Carrier lost
200 = CTS lost
100 = DMA underrun
80 = Transmission deferred because link was busy
40 = Collision detected during interframe spacing

(SQE/Heartbeat detected)
20 = Excessive collisions
10 = Reserved

The lowest nibble (bits 3 to 0) are a count of collisions during this
transmission. For example:

~8802~ = Complete, Late collision, 2 collisions
~8841~ = Complete, Late Collision, SQE detected, 1 collision

3.2.5 erase

The erase command erases the contents of non-volatile memory,
including the Micro-CS’s IP address. This command also restores the
parameters to their factory defaults. The syntax is:

erase

If the self-boot option is installed, the erase command prompts for which
non-volatile memory to erase: EEPROM or FLASH. Entering 1 at the
prompt causes the Micro-CS to erase the EEPROM memory
(configuration information); entering 2 at the prompt causes the
Micro-CS to erase the Flash memory (self-boot image).

The erase command display looks like this:

3-20 Micro-CS Installation Guide

Commands

3.2.15 sequence

The sequence command edits the load/dump interface list. This list
determines the order of the network interfaces, and either the local area
network (LAN) or the SLIP interface the Micro-CS will use for loading
and dumping. The default, net, uses the LAN interface. The list can
contain up to four interfaces. If the Micro-CS fails to boot using the first
interface, it will try the next, and then the next interface, and then repeat
the sequence. The command syntax is:

sequence [–d] | [interface[,interface]. . .]
Specify the LAN interface by selecting net; specify each SLIP interface

as slnn, where nn is a port number; and specify self-boot by selecting self.
Separate each interface with a comma or a space. Enter the interface list
as an argument to the command; otherwise, the console displays a list of
available interfaces and prompts for a new list.

In the following example, interfaces are assigned to the load/dump
sequence list. Ports 12, 14, and 15 can be added to the list because they
were configured earlier as SLIP interfaces:

monitor:: sequence
Enter a list of 1 to 4 interfaces to attempt to use for
downloading code or upline dumping. Enter them in the order
they should be tried, separated by commas or spaces. Possible
interfaces are:

Ethernet: net
SL/IP: sl12,sl14,s115
SELF: self

Enter interface sequence [net]:: sl12, net

Interface sequence: sl12,net

The

SELF

NOTE

option appears only if the self-boot image is loaded.

Micro-CS Installation Guide 3-21

Chapter 3: ROM Monitor Commands

If you enter the command with the –d argument, the console displays the
current load/dump interface list. You cannot specify both the –d argument
and the interface list with the same command. The sequence –d
command display looks like this:

monitor:: sequence -d
Interface sequence: sl12,net

Entering a number for a port that has not been configured properly for
SLIP causes the Port nn is not configured for SL/IP message to display,
where nn is the port number.

The Micro-CS can slip boot over any port except Port 1.

NOTE

3.2.16 slip

The slip command defines a serial port as a Serial Line Internet Protocol
(SLIP) interface. This command defines a number of port parameters.
The command syntax is:

slip [–d] [port]
After entering the command, you are prompted for each parameter. The

port is the number of the serial port to be configured with this command.
If you do not enter a port number, you will be prompted for one. Table
3-2 lists the information for which the slip command prompts.

Entering slip –d causes the command to display all the current settings.

CHAPTER 4

TROUBLESHOOTING PROCEDURES

4.1 GENERAL

The Micro-CS’s front panel displays 4 system indicators and 9 status
indicators. The system indicators are labeled STATUS, NET, ATTN,
and SETUP. The status indicators are labeled 1 through 7, M(odem), and
INT.

The system indicators provide information about normal operations and
about problems that occur. Use these indicators and the ROM Monitor
commands to diagnose problems.

The status indicators display port activity during normal operations; each
indicator supports 1 port.

During power-up and booting it is more complicated to diagnose
problems because they can originate in the Micro-CS or the load server
host. However, the indicators provide both a progress report and an error
display to assist you in troubleshooting.

4.2 POWER-UP AND BOOT PROCEDURES

The Micro-CS has two modes of operation: normal and SETUP. Normal
mode is the standard operational mode. Set Up mode provides access to
the ROM Monitor commands. Pressing the SETUP switch on the front
panel within 3 seconds of powering–up puts the Micro-CS into SETUP
mode. When the Micro-CS is in SETUP mode the SETUP indicator
lights.

During the power-up and boot sequence the Micro-CS performs a set of
diagnostics. The system indicators display the diagnostics status. The
Micro-CS stops when it detects one of two error conditions (see Table
4-2). The pattern of the system indicators identifies the error condition.

4.2.1 Normal Mode

Upon power-up or reset the Micro-CS enters normal mode. The following
subsections describe both the possible error and error-free conditions that
can occur during power-up and booting in normal mode.

Micro-CS Installation Guide 4-1

Chapter 4: Troubleshooting Procedures

4.2.1.1 Normal Mode Error-free Sequence

Table 4-1 summarizes the indicator display sequences during error-free
power-up in normal mode.

Activity N1: Testing Indicators

All front panel indicators light for a few seconds then all turn off,
confirming that all indicators are operational.

Activity N2: Testing the Hardware

During the power-up sequence the Micro-CS runs a series of self-test
diagnostics. These diagnostics test internal hardware functions. If a test
fails, the ATTN and STATUS LEDs flash and an error message is
displayed, if the console port is selected. The NET indicator flashes
during the power-up self-tests. After the tests are complete, only the
STATUS LED stays on.

4.2.1.2 Normal Mode Error States

Table 4-2 shows the state of the indicators when an error occurs at given
stages of the start-up process. For example, if the Micro-CS fails during
the testing hardware state (N2), the error condition is hardware failure
NE2. A description of possible causes and solutions for each error
condition follows Table 4-2.

Activity NE5: Booted Wrong Image

The Micro-CS has just loaded an inappropriate image. Pressing the
SETUP switch for approximately 3 seconds to generate a reset clears this
error. The Micro-CS loads inappropriate images if one of the following
operator errors occur:

• Configuring the Micro-CS with an incorrect file name or renaming or

copying the image file to the wrong name.

• Supplying the wrong name to any of the boot commands (na boot,

dumpboot, or the superuser CLI boot).

If you are uncertain as to why the Micro-CS booted the wrong image,
enter Set Up mode and issue an image -d command. This command
shows which host file the Micro-CS is trying to load.

SETUP Mode

Pressing the SETUP switch within 3 seconds of either a reset or cycling
on power puts the Micro-CS into Set Up mode. The SETUP indicator is
on after pressing the SETUP switch.

Micro-CS Installation Guide 4-3

indicators are operational. At this point the Micro-CS is in normal mode.
Press the SETUP switch to put the Micro-CS into monitor mode.

Activity T2: T esting the Hardware

During power-up the Micro-CS runs self-tests that execute CPU
diagnostics, ROM and E2 PROM, flash checksums, refresh, internal
serial port and LAN loopbacks, and RAM tests. The NET indicator
flashes during the tests. After completing the power-up self-tests the
STATUS indicator remains on.

Activity T3: At the Monitor Prompt

When the STAT and ATTN indicators are on, the ROM Monitor prompt
displays on the console terminal. Enter the boot command at the prompt.

Micro-CS loads inappropriate images if one of the following operator
errors occurs:

• Configuring the Micro-CS with an incorrect file name or renaming or

copying the image file to the wrong name.

• Supplying the wrong name to the boot command.

4.3 BOOT FAILURES

The procedures for troubleshooting a power-up failure established that

• the hardware is functional

• the Ethernet interface is functional

• the Micro-CS can communicate with the Ethernet

If the Micro-CS still is not booted, you must pinpoint the problem. The
boot error report can help in this process.

Micro-CS Installation Guide 4-5

Chapter 4: Troubleshooting Procedures

The Micro-CS generates a boot error report only if it opens the

NOTE

boot file and an error occurs during the boot process.

Generally, two problems cause boot failures: the Micro-CS is not
configured properly, or the load server host is not responding. The
Micro-CS requests a boot either from a pre-defined load host, or by
broadcasting its boot request. When a host responds, the Micro-CS loads
its operational code.

The Micro-CS requires setting certain configuration parameters. Enter
these parameters with ROM Monitor commands for the initial boot
sequence. See Chapter 3 for more information on these commands.

If the problem is a non-responsive host the boot error report displays that
information under the Rsp T/O’s: field. This field indicates that the
Micro-CS timed out while waiting for a response to its boot request; if
this field is empty, check the Micro-CS’s configuration parameters.

Boot Error Report

If an error occurs, a boot error report is generated only if the Micro-CS
has opened the boot file. The report uses the following format:

BOOT ERROR REPORT (for BFS files only)
Boot attempt from host nn.nn.nn.nn:
Errors from Last Open Request:
0 ARP errors 0 ERPC layer errors 0 Aborts rx’d
Errors from Last Read Request:

Errors from Last ERPC Layer Invocation:
0 H/W errors 1 Msgs from wrong host 0 Rsp T/O’s 0 Msgs of wrong type

NOTE

The Micro-CS generates a boot error report for the Internet address from
which it tried and failed to boot. Table 4-5 describes the Errors from Last
Open Request; Table 4-6 describes the Errors from Last Read Request;
and Table 4-7 describes the Errors from Last ERPC Layer Invocation.

TFTP error codes.

4-6 Micro-CS Installation Guide

Boot Failures

The error count pinpoints the error that caused the boot failure. For
example, if the boot failed during a Read Request due to excessive
Expedited Remote Procedure Call (ERPC) layer errors, the Errors from
Last ERPC Layer Invocation lists only errors that occurred during the
failed Read Request. The report does not list errors that occurred during
any other Read Request or during the Open Request.

The Open Request and the Read Request layers communicate with the
block file server (BFS) on the host. The ERPC layer resides below the
Open Request and the Read Request layers. It is responsible for sending a
given message to a specific host UDP port and for receiving the correct
response to that message from the port.

4.4 CORRECTING MICRO-CS PARAMETERS

The following parameters must accurately reflect both the Micro-CS and
the network environment in which it operates:

• Verify the Micro-CS’s Internet address using the addr command.

• If your network configuration does not support the factory defaults,

verify the following parameters using the addr command:

- The broadcast address.

- The subnet mask.

- The load/dump gateway address (which must be specified if the

preferred load server host is located on another network or
subnet).

- The IP encapsulation type. Many systems hav e hardware Ethernet

interfaces that are IEEE 802.3 compliant but very few actually do

802.3 IP packet encapsulation. Use the default, Ethernet, unless
you know absolutely that your LAN does 802.2/802.3 IP packet
encapsulation.

4-8 Micro-CS Installation Guide

Load Server Host Not Responding

• Unless otherwise stated, if you are using a SLIP interface to boot the

Micro-CS, verify the following using the slip command:

- The port is configured as a SLIP interface.

- The Internet address for the SLIP network interface.

- The Internet address for the remote end of the SLIP connection.

- The Internet address for the load/dump host (this must be specified

if the remote end is a gateway and not a load host).

- The SLIP network interface is included in the load/dump interface

list (use the sequence command).

Both the name of the image file containing the Micro-CS’s software and
the address of the preferred load server host can be defaulted. If the value
for the image name is incorrect, the Micro-CS cannot boot. Correct the
name using the image command. If the address for the preferred load
server host is incorrect, the boot takes longer, since the Micro-CS has to
broadcast for a host. Correct the load host’s address using the addr
command.

Confirm that the Micro-CS boot parameters are correct by using the
appropriate ROM Monitor commands. Modify any boot parameters that
are incorrect or missing. Boot the Micro-CS either by entering the boot
command at the console, or by pressing the SETUP switch approximately
3 seconds to generate a reset, followed by an automatic boot.

4.5 LOAD SERVER HOST NOT RESPONDING

The Micro-CS can boot from one of four types of hosts acting as a load
server host:

• A UNIX host on the local area network.

• A UNIX host at the end of a SLIP interface.

• Another Micro-CS.

• Any host (UNIX or non-UNIX, using tftp).

The following sections discuss troubleshooting for each of these load
server hosts.

Micro-CS Installation Guide 4-9

Chapter 4: Troubleshooting Procedures

UNIX Host on the LAN

When troubleshooting a UNIX host on the LAN, make sure

• The host is booted and functioning properly.

• The host can communicate with other network nodes using standard

UNIX networking features and utilities.

• All Micro-CS software is installed properly on the host. (See the

CSMIM2 Installation Notes.)

• The erpcd daemon or tftp server, which loads the operational image

to the Micro-CS, is running.

In SETUP mode, Micro-CS displays the boot progress report on the
console.

• To place the Micro-CS into SETUP mode, press the SETUP switch

after a reset and wait for monitor prompt.

• To place erpcd on the load server host into test mode, kill the erpcd

program (requires superuser privileges) and restart it using the -D
option:

# /etc/erpcd -D

When the Micro-CS boots in SETUP mode the console displays the load
server host’s Internet address and indicates whether it receives a response
to its Open File Request and to any of its Read File Requests.

The host’s progress report indicates receipt of any File Server Requests
and its responses to such requests. The host displays erpc_return 0 if it
successfully receives a request and is sending out an af firmati v e response.
If any Micro-CS related files are missing or cannot be installed, contact
technical support.

4-10 Micro-CS Installation Guide

Load Server Host Not Responding

UNIX Host on a SLIP Interface

When troubleshooting a UNIX host at the end of a SLIP network
interface, make sure

• The host is booted and functioning properly.

• The SLIP link is connected correctly.

• The Internet addresses are correct for both sides of the SLIP link.

• All Micro-CS software is installed properly on the host. See the

CSMIM2 Installation Notes.

• The erpcd daemon or tftp server, which loads the operational image

to the Micro-CS, is running.

A PC host running the XENIX operating system has both the erpcd and

slipd daemons (provided with the distribution and installed in the file
/etc) running in the background on the PC. Set the Micro-CS and the
erpcd on the load host into Set Up mode:

• For the Micro-CS, press SETUP following a reset and wait for the

monitor prompt.

• For erpcd on the load server host, as superuser , kill the erpcd program

and restart it using the -D option:

# /etc/erpcd -D

Another Micro-CS

When troubleshooting a Micro-CS configured as a load server host

• Use the CLI telnet command to access the unit and verify that it is up

and running.

• Communicate with the unit on the Ethernet using the superuser CLI

ping command. Ping is also available through the monitor command.

• Verify the unit’s configuration using na or the admin command.

The CSMIM Network Administrator’s Guide provides more information
on these commands.

Micro-CS Installation Guide 4-11

Chapter 4: Troubleshooting Procedures

Be aware that the Micro-CS can only boot another Micro-CS that has the
same configuration. Thus, a Micro-CS with only 2MB of RAM and no
option keys enabled cannot boot a Micro-CS with 4 MB of RAM and the
IPX option enabled.

A Micro-CS that has been reconfigured as a load server host, but not
rebooted, cannot boot another Micro-CS on the network. Rebooting the
Micro-CS load server host ensures that the parameters are set.

4.6 MICRO-CS DUMPS

The Micro-CS dumps its memory image to a host running load server
software when certain software or hardware events occur. Events that
trigger Micro-CS dumps are

• Non-recoverable hardware or software errors.

• Software fails to reset the Micro-CS’s watchdog timer.

• Software fails one or more internal consistency checks.

• Hardware detects an internal fault.

Dump files are generated for use by technical support

NOTE

Key:

personnel only.

Table 4-8 Indicator States during a Dump

Activity
Dump

STATUS
green

● ● ■

ATTN
amber

● = On continuously ■ = Flashing irregularly

NET
green

The Micro-CS sends a dump file to a preferred load dump host. If you do
not define this host by specifying an address, the Micro-CS broadcasts a
request and dumps to the first host running erpcd daemon that responds.

The dump creates a file in the dump host’s directory, named
/usr/spool/erpcd/bfs, and assigns a unique file name for each Micro-CS
but not for each crash dump. For each dump, the Micro-CS overwrites the
existing file.

4-12 Micro-CS Installation Guide

Micro-CS Dumps

The assigned name depends on the number of characters per file name
that the dump host supports. For hosts supporting file names longer than
14 characters (e.g., BSD hosts), dump files are named dump.addr. The
file extension addr is the Micro-CS’s Internet address.

For hosts that limit file names to 14 characters (e.g., System V hosts), a
dump creates two additional directories under /usr/spool/erpcd/bfs. The
name of the first directory is dump; the second directory uses the
Micro-CS’s Internet network address as its name. The dump file uses the
Micro-CS’s Internet host address as its name.

Each dump file contains a complete image of the Micro-CS RAM
memory and hardware state. The amount of space required for a dump file
varies according to the port configuration. The ROM Monitor config
command displays the amount of memory for the Micro-CS. Table 4-9
shows sample dump file names. All pathnames are relative to the file
/usr/spool/erpcd/bfs.
