Introduction

1.5.3 Terminal and Communications Access

The CSMIM2 provides terminal and communications access to users on a
local area network. The CSMIM2 can connect up to 7 asynchronous serial
devices to host computers on a LAN.

1.5.4 Backplane Connectivity and Mangement

The CSMIM2, through the use of Repeater Interface Controller (RIC)
technology is capable of operating on any one of the three separate
segments (Ethernet channels A, B or C) located on the Multi Media
Access Center (MMAC) backplane. Channels are initially
user-configured using jumpers but may be changed using software
commands via local management with the EMME or EMM-E6 Ethernet
Management Modules.

1.5.5 System Description

The CSMIM2 is a powerful 32-bit device that comes with an Intel 80486
SXLC2 clock-doubled processor. The CSMIM2 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 CSMIM2
commands, you can:

•

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 CSMIM2 manually.

Using the ROM Monitor

The CSMIM2 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 CSMIM2 configured as a load server, or
from self-contained Flash Memory.

1-4 CSMIM2 Installation Guide

CSMIM2 Overview

The CSMIM2 has a watchdog timer that is reset by the software at regular
intervals. The watchdog timer reboots the CSMIM2 in the unlikely event
of an internal software error. This feature allows the CSMIM2 to run for
long periods of time without intervention.

A modem upgrade for the CSMIM2 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.

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 Netw ork Acti vity, diagnostic failure and
other fault connections.

and pin 1, and the J12 jumper over the center pin and pin 3.

• To operate on Channel C: Place the J11 jumper over the center pin

and pin 3, and the J12 jumper over the center pin and pin 1.

2.3.3 Setting the Unmanaged Module Jumper

CSMIM2s allow grouping of the B and C channels into unmanaged
modules to provide two additional Ethernet networks. All MIMs in the
MMAC to the left of the CSMIM2 become part of the unmanaged module
group. These additional networks cannot be seen or controlled from the
EMME or EMM-E6 installed in the MMAC.

Unmanaged Module Group jumper settings can be overridden

NOTE

by an EMME or EMM-E6 installed in the MMAC.

To set the unmanaged module group jumper, refer to Figure 2-1 and
configure the jumper as follows:

• To operate normally (maintain the continuity of the backplane):

Place the J15 jumper over the center pin and pin 3.

• To operate in Unmanaged Module Group mode: Place the J15

jumper over the center pin and pin 1.

removing modules, even though Cabletron Systems modules
have “hot swap” capabilities.

1. Remove the safety bars that protect the chassis and remove any

module to be replaced or blank MMAC slot covers, in accordance with
the installation and removal procedures for these items.

2. Holding the CSMIM2 by the front panel, or by the edges of the board,

align the bottom and top edges of the board with the guides. Make sure
that both the bottom and top edges of the card rest in these guides.

3. Slide the CSMIM2 (Figure 2-2) into the desired slot of the MMAC

card cage.

4. Firmly press the module connections into the backplane. Do not try to

force the module into place or use the knurled knobs to draw the

Console Port Terminal

2.5 CONSOLE PORT TERMINAL

Connect a terminal to port 1. You need this terminal to access the ROM
Monitor and boot the CSMIM2 for the first time. 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 CRT-based and
displays the backspace (BS) character accordingly.

Press Set Up within 3 seconds of powering up, to put the CSMIM2 into
ROM Monitor mode. You can also reset and set up the CSMIM2 by
pressing Set Up until all port activity LEDs are ON, then press Set Up
again within 3 seconds to put the server into ROM Monitor mode.

The red ATTN light is ON when the unit is in ROM Monitor

NOTE

state.

2.6 SERIAL DEVICES

The CSMIM2 provides 16 or 32 connections, depending on the port
configuration. The MODMIM provides 16 serial ports as well as 4 to 12
V.32 bis terbo modems.

The CSMIM2/MODMIM 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. Cabletron only
guarantees operation with cables that conform to the appropriate
specification. Table 2-1 lists the maximum recommended cable lengths.

The CSMIM2 can incur damage if the cables conduct transients

!

CAUTION

such as those induced by lightning strikes, etc.

Table 2-1 Maximum Recommended Cable Lengths

Line Speed Cable Length: Feet Meters

50 to 19.2kbps 250 75

CSMIM2 Installation Guide 2-7

Chapter 2: Installing the CSMIM2

If you exceed these recommended cable lengths, you must

NOTE

compensate for any resulting problems by reducing the baud
rate, using low capacitance cable, etc. Exceed these distances
at your own risk.

2.7 POWER-UP AND TEST

1. Apply power (insert into MMAC).

The CSMIM2 now runs its ROM-resident power-up diagnostics. The
indicators momentarily light and then turn off, except for the Ethernet

Segment indicator (by default B).

2. Set the CSMIM2 into Set Up mode (S/U LED on).

Press the Set Up switch on the front panel. The S/U indicator lights
when the unit enters Set Up mode.

You must press the Set Up switch within 3 seconds of either

NOTE

powering-up or Reset to enter Set Up mode.

Next, the CSMIM2 runs diagnostic tests causing the Traf indicator to
flash. If the diagnostics complete successfully, the Stat 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 3.

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.

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
CSMIM2 assumes there is no gateway.

CSMIM2 Installation Guide 2-9

Chapter 2: Installing the CSMIM2

2.8 AUTO-INITIALIZING THE ROMS

The CSMIM2 supports the BOOTP and RARP protocols. The ROMs use
these protocols to obtain boot information without requiring any manual
set-up on the CSMIM2.

• 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 CSMIM2’s Internet Address is not initialized. Under
this condition, the CSMIM2 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 CSMIM2 either prompts the user for
the Internet address (if in Set Up mode) or it lights the Attn LED to
indicate the Internet address is not set (if in Normal mode).

For a successful BOO TP retrie v al, a bootpd must be running on a host on
the same network as the CSMIM2 and must have the appropriate
information in the bootptab file. The CSMIM2’s BOOTP
implementation adheres to rfc951, rfc1048, and rfc1084. Below is a
sample bootptab file entry used to initialize the CSMIM2 named
terminator.

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

terminator:ht=1:ha=00802d004879:ip=132.245.22.226:tc=csmimde­fault:

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 CSMIM2’s Internet Address; ha is the CSMIM2’s hardware

address (Ethernet Address); and

• vm is the Vendor Magic Cookie.

2-10 CSMIM2 Installation Guide

Auto-initializing the ROMs

When the CSMIM2 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
(CSMIM2 in this case) with whatever format the client requests; the
CSMIM2 (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 CSMIM2’s preferred load

NOTE

host.

If the CSMIM2 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
CSMIM2 and the the host’s ARP table must be initialized with the
CSMIM2’s Internet and Ethernet addresses (see the arp man page,
arp -s).

The only boot information that RARP provides is the CSMIM2’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 CSMIM2 its boot information must be running on
the same network as the CSMIM2 because the CSMIM2 only broadcasts
BOOTP and RARP queries.

CSMIM2 Installation Guide 2-11

Chapter 2: Installing the CSMIM2

2.9 SOFTWARE INSTALLATION PROCEDURES

Install the operational code on a UNIX host before loading it on a
CSMIM2. The CSMIM2 Installation Notes describe how to install
software on a host. The CSMIM2 may also be booted from software
loaded on a CSMIM, another CSMIM2 or from Flash memory (see
Chapter 3). When loading the CSMIM2 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 CSMIM2’s Internet address.
Modify any other parameters that the CSMIM2 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 CSMIM2 using a Serial Line Internet Protocol

(SLIP) network interface, you must:
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 CSMIM2 is up
and running.

2-12 CSMIM2 Installation Guide

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 CSMIM2 is
in SETUP mode. Pressing the SETUP switch within 3 seconds of
powering up puts the CSMIM2 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 CSMIM2; 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
CSMIM2’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
CSMIM2 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. The CSMIM Network
Administrator’s Guide (p/n 9031101) describes the na program in detail.
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 CSMIM2 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 CSMIM2’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 CSMIM2 Installation Guide

Commands

The CSMIM2 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 CSMIM2
from a UNIX load host. If you do not define an IP address for the
CSMIM2, it will attempt to learn the address using BOOTP or RARP. If
you do not define a subnet mask, the CSMIM2 uses the generic mask for
the specified IP address.

The CSMIM2 tries to boot from a preferred UNIX load host. If you do not
define a preferred load host, the CSMIM2 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 CSMIM2 uses the broadcast address parameter when loading a file.
If this parameter contains a specific address (for example,

132.245.6.255), the CSMIM2 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 CSMIM2
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 CSMIM2 from
booting.

CSMIM2 Installation Guide 3-5

Chapter 3: ROM Monitor Commands

3.2.2 boot

The boot command requests the loading of appropriate CSMIM2
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

CSMIM2 will hang as it searches for the image. You must press

RESET button to recover.

the
A successful boot disables the Console and the ROM monitor.

The boot command accepts a file name for the CSMIM2’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
CSMIM2, boot requests the default file oper.56.enet. You can also enter
a file name using the image command.

The CSMIM2 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 CSMIM2 broadcasts on the Ethernet and loads
from the first host that responds.

To initiate loading, the CSMIM2 sends a load request message to the
selected host. After receiving a response, the CSMIM2 loads its
operational code to RAM memory. When loading is complete, it transfers
control to the newly-loaded program. The CSMIM2 displays a symbol on
the console for each data block received during the boot.

When the CSMIM2 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 CSMIM2 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 CSMIM2 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

3.2.14 ports

The ports command tests serial line ports, exercising both the data lines
and the control lines for each serial port specified. The syntax for this
command is:

ports [–d]
Each serial port to be tested must be looped-back with a loopback plug to

test both the data lines and the control lines (the accessory kit provides a
loopback plug). Connect this plug to the connector on the CSMIM2 that
corresponds to the port to be tested.

Do not run the ports command for a port to which a device is

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 CSMIM2 will use for loading
and dumping. The default, net, uses the LAN interface. The list can
contain up to four interfaces. If the CSMIM2 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:

CSMIM2 Installation Guide 3-21

Chapter 3: ROM Monitor Commands

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.

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 CSMIM2 can slip boot over any port except Port 1.

CHAPTER 4

TROUBLESHOOTING PROCEDURES

4.1 GENERAL

The CSMIM2’s front panel displays 4 system indicators and 16 or 32
status indicators. The system indicators are labeled Stat, Traf, Attn, and
S/U. The status indicators are numbered 1 through 32. The MODMIM
and the MODEXT cards display 5 LED indicators, CTS, DTR, TXD,
RXD, DCD, per modem port.

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 CSMIM2 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 CSMIM2 has two modes of operation: normal and Set Up. Normal
mode is the standard operational mode. Set Up mode provides access to
the ROM Monitor commands. Pressing the Set Up switch on the front
panel, within 30 seconds of powering–up, puts the CSMIM2 into Set Up
mode. When the CSMIM2 is in Set Up mode, the S/U indicator lights.
Figure 1-3 in Chapter 1 illustrates the CSMIM2’s front panel.

During the power-up and boot sequence, the CSMIM2 performs a set of
diagnostics. The system indicators display the diagnostics’ status. The
CSMIM2 stops when it detects one of two error conditions (see Table
4-2). The pattern of the system indicators identifies the error condition.

CSMIM2 Installation Guide 4-1

Chapter 4: Troubleshooting Procedures

4.2.1 Normal Mode

Upon power–up or reset, the CSMIM2 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.

4.2.1.1 Normal Mode Error-free Sequence

4.2.1.2 Activity N1: Testing Indicators

All front panel indicators light for a few seconds, then all but the
Ethernet channel indicator (segment indicator) turn off, confirming that

all indicators are operational.

4.2.1.3 Activity N2: Testing the Hardware

During the power-up sequence, the CSMIM2 runs a series of self-test
diagnostics. These diagnostics test internal hardware functions. If a test
fails, the Attn and Stat LEDs flash and an error message is displayed if
the console port is selected. The Ethernet Channel indicator lights for a
few seconds, then the Traf indicator flashes during the power-up
self–tests. After the self–tests complete, only the Stat and Ethernet
Channel indicators remain on.

4-2 CSMIM2 Installation Guide

Power-up and Boot Procedures

4.2.1.4 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 CSMIM2 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.

service. Call technical support.

4.2.1.6 Activity NE5: Booted Wrong Image

The CSMIM2 has just loaded an inappropriate image. Pressing the Set
Up switch for approximately 3 seconds to generate a reset clears this

error. The CSMIM2 loads inappropriate images if one of the following
operator errors occur:

• Configuring the CSMIM2 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 CSMIM2 booted the wrong image,
enter Set Up mode and issue an image -d command. This command
shows which host file the CSMIM2 is trying to load.

This sequence confirms that all indicators are operational. At this point,
the CSMIM2 is in normal mode. Press the Set Up switch to put the
CSMIM2/MODMIM into monitor mode.

4.2.2.3 Activity T2: T esting the Hardware

During power-up, the CSMIM2/MODMIM runs self-tests that execute
CPU diagnostics, ROM and E2 PROM, flash checksums, refresh, internal
serial port and LAN loopbacks, and RAM tests. The Traf indicator
flashes during the tests and after completing the power-up self-tests, the
Stat and Ethernet channel indicators remain on.

Power-up and Boot Procedures

4.2.2.4 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.
If you did not enter a file name with the command, a prompt asks you for
one.

4.2.2.5 Set Up Mode Error States

Table 4-4 describes the state of the indicators if errors occur at different
stages of the start-up process. For example, if the CSMIM2 fails while

service. Call technical support.

4.2.2.7 Activity TE7: Booted Wrong Image

The CSMIM2 loaded an inappropriate image. Pressing the Set Up switch
approximately 3 seconds to generate a reset clears this error. The
CSMIM2 loads inappropriate images if one of the following operator
errors occurs:

• Configuring the CSMIM2 with an incorrect file name, or renaming or

copying the image file to the wrong name.

• Supplying the wrong name to the boot command.

CSMIM2 Installation Guide 4-5

Chapter 4: Troubleshooting Procedures

4.3 BOOT FAILURES

The procedures for troubleshooting a power-up failure established that:

• the hardware is functional

• the Ethernet interface is functional

• the CSMIM2 can communicate with the Ethernet.

If the CSMIM2 still is not booted, you must pinpoint the problem. The
boot error report can help in this process.

The CSMIM2 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 CSMIM2 is not
configured properly, or the load server host is not responding. The
CSMIM2 requests a boot either from a pre-defined load host, or by
broadcasting its boot request. When a host responds, the CSMIM2 loads
its operational code.

The CSMIM2 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
CSMIM2 timed out while waiting for a response to its boot request; if this
field is empty, check the CSMIM2’s configuration parameters.

4-6 CSMIM2 Installation Guide

Boot Failures

4.3.1 Boot Error Report

If an error occurs, a boot error report is generated only if the CSMIM2 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:
0 Msgs w/ wrong size 0 ERPC layer errors 0 Aborts rxd
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

TFTP error reporting complies with the standard, pre-defined

NOTE

TFTP error codes.

The CSMIM2 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.

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.

requested file does not exist on that server. Run erpcd -D
on the host to obtain more information.

Boot Failures

4.3.2 Correcting CSMIM2 Parameters

The following parameters must accurately reflect both the CSMIM2 and
the network environment in which it operates:

• Verify the CSMIM2’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 fe w 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.

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

CSMIM2, 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 CSMIM2’s software, and
the address of the preferred load server host can be defaulted. If the value
for the image name is incorrect, the CSMIM2 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 CSMIM2 has to
broadcast for a host. Correct the load host’s address using the addr
command.

CSMIM2 Installation Guide 4-9

Chapter 4: Troubleshooting Procedures

Confirm that the CSMIM2 boot parameters are correct by using the
appropriate ROM Monitor commands. Modify any boot parameters that
are incorrect or missing. Boot the CSMIM2 either by entering the boot
command at the console, or by pressing the Set Up switch approximately
3 seconds to generate a reset, followed by an automatic boot.

4.3.3 Load Server Host Not Responding

The CSMIM2 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 CSMIM2.

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

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

4.3.4 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 CSMIM2 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 CSMIM2, is running.

ps -ef | grep erpcd

4-10 CSMIM2 Installation Guide

Boot Failures

In Set Up mode, both the CSMIM2 and erpcd on the load server host
display boot progress reports. The CSMIM2 displays its reports on the
console; erpcd displays its reports on the terminal that invokes test mode.

• To place the CSMIM2 into Set Up mode, press the Set Up 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 CSMIM2 boots in Set Up 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 affirmative response.
If any CSMIM2-related files are missing or cannot be installed, contact
technical support.

4.3.5 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 CSMIM2 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 CSMIM2, 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 CSMIM2 and the
erpcd on the load host into Set Up mode:

CSMIM2 Installation Guide 4-11

Chapter 4: Troubleshooting Procedures

• For the CSMIM2, press Set Up 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

4.3.6 Another CSMIM2

When troubleshooting a CSMIM2 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.

• Verify the unit’s configuration using na.

The CSMIM2 Network Administrator’s Guide provides more information
on these commands.

A CSMIM2 that has been reconfigured as a load server host, but not
rebooted, cannot boot another CSMIM2 on the network. Rebooting the
CSMIM2 load server host ensures that the parameters are set.

4.3.7 CSMIM2 Dumps

The CSMIM2 dumps its memory image to a host running load server
software when certain software or hardware events occur. Events that
trigger CSMIM2 dumps are:

• Non-recoverable hardware or software errors.

• Software fails to reset the CSMIM2’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

Dump l l n

Stat

green

Key: ● = On continuously ■ = Flashing irregularly

The CSMIM2 sends a dump file to a preferred load dump host. If you do
not define this host by specifying an address, the CSMIM2 broadcasts a
request and dumps to the first host 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 CSMIM2
but not for each crash dump. For each dump, the CSMIM2 overwrites the
existing file.

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 CSMIM2’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
CSMIM2’s Internet network address as its name. The dump file uses the
CSMIM2’s Internet host address as its name.

Each dump file contains a complete image of the CSMIM2 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 CSMIM2. Table 4-9 shows
sample dump file names. All pathnames are relative to the file
/usr/spool/erpcd/bfs.
