INTRODUCTION

1.5 CSMIM-T1 OVERVIEW

The CSMIM-T1 is a dual-slot, Annex Software compatible system
designed to reside in the MMAC series of hubs. The module takes the
existing CSMIM2 core and adds enhanced processing power in the form
of dual 486SXLC2-40 clock doubled processors. Both the main and
secondary processors have been upgraded, which allows the main
processor to control the MMAC network interfaces, while the second
controls the serial ports. These processors have access to a minimum of
4 MB DRAM (standard), but may be upgraded to 8 MB through the
installation of SIMM modules. This memory is shared between the
processors, and arbitrated on a cycle by cycle basis.

Extensive power up diagnostics are provided to confidence check the
system prior to the loading of application software. A Console Port is
used for system setup, booting, and diagnostic purposes. After booting,
the Console Port is idle. System boot is accomplished either from a UNIX
host, a VAX VMS host, or an optional Flash PROM. If you are operating
from Flash only , be aware that host based services such as security are
supported. If you have any questions, contact Cabletron Technical
Support.

not

It should be mentioned that although the CSMIM-T1 is capable of
running in a Novell environment, it will not boot from a Novell server. In
a Novell environment, the module must be booted either from a UNIX
server, or from Flash.

There are 24 V.34 modems in the CSMIM-T1. Access for the T -1 network
is provided by a single RJ48C connector on the front panel. Data received
from the T-1 network is either moved through the CSMIM-T1 module and
onto the Ethernet backplane, or fed back out through the Drop and Insert
Interface on the front panel. An example of this would be connecting the
Drop and Insert Interface to a PBX for voice applications.

• Macintosh (AppleTalk)

Refer to the software document set for a description of the supported
software features.

In addition to the standard software package, the CSMIM-T1 software
distribution includes a number of T-1 specific commands and parameters
that are used for configuration and administration. Refer to Chapter 4,

CSMIM-T1 Parameters

for a description.

1.6 CSMIM-T1 FRONT PANEL

The CSMIM-T1 LED indicators provide the user with feedback on

Ethernet Channel Indicators

There are three green LEDs that indicate the Ethernet channel
(A, B, or C) that is selected by either the software or by jumper
configuration.

1.6.3 The SET UP Switch

The SET UP Switch allows the user to change the operational mode of the
module from normal to set up. When the module powers up, it
automatically enters the normal mode. To enter the SET UP mode, the
SET UP switch must be depressed within 30 seconds of power-up. When
the S/U LED lights, the unit is in the SET UP mode.

Depressing the SET UP Switch at any time for approximately three
seconds causes the module to enter a RESET state. This is the equivalent
of a reboot. The green S/U LED will flash while the unit executes power
up diagnostics, and the SET UP mode can be entered.

INTRODUCTION

1.6.4 T-1 Network Access

There are two ports on the front panel that allow access to the T-1
network. The T-1 Network Interface Port is an 8-pin, RJ48C port that
provides access for the digital T-1 line. The Drop/Insert Interface is also
an 8-pin, RJ48C port, and provides connection to a local Private Branch
Exchange (PBX), or other equipment, such as an ETWMIM equipped
with a T-1 interface.

In addition to these ports, there are 8 Status LEDs that provide the user
with valuable information regarding the T-1 network.

DI SYNC

The green DI SYNC LED is ON when the T-1 engine is detecting frame
synchronization on the Drop and Insert Interface. The LED is off when
there is a Loss of Frame (LOF) synchronization.

An LOF condition causes the T-1 engine to transmit all unframed ones
(keep alive signal) to the device attached to the Drop and Insert Interface.

ON LINE LED

The green ON LINE LED is ON when the T-1 engine is connected to the
network interface.

1.6.5 NETWORK STATUS / ALARMS

TEST - Network Test

This red indicator is ON when the T-1 engine network interface is placed
into a test loopback condition. Loopback tests are activated either locally
by the user, or by the telco provider.

SYNC - Synchronized

This green indicator is ON when the T-1 engine is properly synchronized
with the network signal and is receiving proper framing information.

LOS - Loss of Signal

This red indicator is ON when the T-1 engine is detecting no signal
(pulses) on the network interface receiver. When a LOS condition exists
the T-1 engine transmits unframed all ones (Alarm Indication Signal) to
the network.

1-8 CSMIM-T1 Hardware Installation Guide

CSMIM-T1 Front Panel

RED - Red Alarm

This red indicator is ON during a locally detected carrier failure. During
the “red” alarm condition, a “yellow” alarm is transmitted to the
telephone network.

YEL - Yellow Alarm

This yellow indicator is ON when receiving a “yellow” alarm condition
from the telephone network.

BLU - Blue Alarm

This blue indicator is ON when receiving an unframed, all ones Alarm
Indication Signal (AIS) from the network. This condition exists upon a
loss of originating signal, or when any action is taken that would cause
signal disruption.

1.6.6 Modem Configuration Status LEDs

To help determine if a problem exists in a modem, there are three
green/amber LEDs labeled 1-8, 9-16, and 17-24. These LEDs indicate
groups of modems installed. When amber, the LED indicates that at least
one modem within the indicated group is in a fault condition. When
green, the LED indicates that diagnostics have determined that the
modems are operating normally.

1.6.7 Modem Port Status LEDs

Each modem has a group of three LEDs to indicate activity. These LEDs
can help determine a fault within a group of modems.

CD - Carrier Detect

This green LED is ON when the carrier has been detected on the
telephone line of the corresponding modem. There are a total of 24 CD
indicators, one per channel.

TX - Transmit Data

This green LED flashes to indicate the corresponding modem is
transmitting data. There are a total of 24 TX indicators, one per channel.

RX - Receive Data

This green LED flashes to indicate the corresponding modem is receiving
data. There are a total of 24 RX indicators, one per channel.

Chapter 1: INTRODUCTION

1.6.8 EFS Key Number

The sticker on the front panel next to the serial number is the EFS Key.
This key is factory loaded and enables all options on the module. The EFS
value is stored in the EEPROM, and will be erased when executing the
“erase” command. It is important that you record this value, in the event
you need to clear the EEPROM. To re-enter the key value, refer to the
procedure in Chapter 2, section 2.7.3.

1.7 CONNECTIVITY

Ethernet Interface Selection

The CSMIM-T1 has a 48 pin DIN connector for connection to the A
Channel Ethernet segment, and a 96 pin DIN connector for B and C
channel attachment. Segment selection is performed by setting jumpers,
but may be overridden by commands from the MMAC management
module.

Jumper position and channel selection is explained in Chapter 2,
Installing the CSMIM-T1.

1.8 TELCO CONNECTION INFORMATION

There are different ways the CSMIM-T1 can be set up. It can use either a
full T-1 line, or a fractional one. In either case, there is specific
information the user needs to get from and provide to the Telco providing
the connection. This section supplies some of the basic information
necessary to set up a T-1 connection.

1.8.1 Connecting the CSMIM-T1 to a Full T-1 Line

In a full T-1 application, all channels of the line are used in the same
manner, such as data lines for multiple computer ports. There is no
peeling off of any channels, and the Drop and Insert Port is not used.
Table 1-1 provides a short list of information necessary to configure a full
T-1 circuit in a Point-to-Point Protocol (PPP) environment.
Configurations may vary depending on the application.

Locating the Ethernet Jumpers

2.2.1 Setting the Ethernet Jumpers

The Ethernet jumpers determine how your CSMIM-T1 operates on the
network. You can set the jumpers so that the CSMIM-T1 operates on
channel A, B, or C. Refer to Figure 2-1 to locate and configure the
jumpers.

There is a single jumper block, labelled J12, that is used to select both the
Ethernet Segment and the Subnet. Pin row A at J12 is used to select the
Subnet. Pin rows B and C are used to select Ethernet Channels. Please use
care in configuring the jumpers. Figure 2-1 shows the default settings
(Channel B) for the CSMIM-T1.

To operate on Channel A: Place jumpers over the center pin and pin 3

•

in pin rows B and C.

• To operate on Channel B: Place one jumper over the center pin and pin

3 in pin row B, and the other jumper over the center pin and pin 1 in
pin row C.

T o operate on Channel C: Place one jumper o ver the center pin and pin

•

1 in pin row B, and the other jumper over the center pin and pin 3 in
pin row C.

2.2.2 Setting the Subnet Jumper

The CSMIM-T1 allows grouping of the B and C channels into a subnet to
provide additional Ethernet networks. All MIMs in the MMAC to the left
of the CSMIM-T1 become isolated on the B and C channel FNB
connector. These additional networks cannot communicate over the B and
C channel FNB connector with any module to the right.

NOTE

CSMIM-T1 Hardware Installation Guide 2-3

Ethernet Channel and Subnet jumper settings can be
overridden by an EMME or EMM-E6 installed in the MMAC.

Chapter 2: INSTALLING THE CSMIM-T1

To set the Subnet jumper, refer to Figure 2-1 and configure pin row A of
J12 as follows:

•

Normal Operation (maintain continuity of the backplane: Default):

Place a jumper over the center pin and pin 3 in pin row A.

• Subnet mode: Place a jumper over the center pin and pin 1 in pin ro w A.

2.3 NETWORK BYPASS JUMPER

The CSMIM-T1 has an internal jumper that is used to select a bypass
mode for the T-1 Engine. The T-1 engine will go into a bypass mode when
the MMAC hub is po wered down, reset, or when the CSMIM-T1 module
is removed from the hub . This jumper is labelled J24, and is located on the
modem board, just behind the T-1 Network Interface port (See Figure
2-2).

Figure 2-2 Network Bypass Jumper

The jumper can be set to Network Loopback Mode (default setting) or
Bypass Mode. Please check your module to see that the jumper is

configured in the default setting before installing into your hub.
Network Loopback Mode loops back all signals on each interface.
The Bypass Mode will connect the DSX1 lines directly to the DS1 lines.

2-4 CSMIM-T1 Hardware Installation Guide

Installing the CSMIM-T1

Using Bypass Mode will allow a connection to the network to be
maintained even though the system is powered down (or not on-line). If
all channels are not being used for modem applications, the DSX1
interface could be used to drop-and-insert the PBX voice channels into
the DS1 connection. (In this example, it requires that the PBX have an
integral T1-CSU to terminate the network.)

In addition to J12 and J24, there are other jumpers on the
module. These are used for diagnostic purposes, or are factory

CAUTION

presets. Changing any of the jumper positions could cause
damage to your module.

2.4 INSTALLING THE CSMIM-T1

Installation should be performed by qualified personnel only.

strap.

When installing the CSMIM-T1, keep the following in mind:

• You may install the CSMIM-T1 in any slot except for slot 1 (farthest

slot to the right) of the MMAC chassis.

• We suggest positioning the CSMIM-T1 next to any contiguous RIC

MIMs or MIMs directly controlled by the hub managing device (e.g.,
EMME, EMM-E6, etc.). This does not apply to shunting
MMAC-FNBs, where the data path remains unbroken, and allows
non-interrupted communication.

Although Cabletron Systems modules have “hot swap”

NOTE

Install the CSMIM-T1 into the MMAC-FNB (backplane) as follows:

capabilities, we recommend that you power down the MMAC
hub prior to installation.

Chapter 2: INSTALLING THE CSMIM-T1

1. Remove Security Bars from MMAC chassis, and blank plates from

desired slots.

2. Holding the CSMIM-T1 by the front panel, or by the edges of the

board, align the bottom and top edges of the board with the guide slots.
Make sure that both of the edges of the card rest in the guide slots.

3. Slide the CSMIM-T1 (Figure 2-2) into the desired MMAC slots.

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
module into the backplane. Forcing a misaligned module into place
can damage the CSMIM-T1 or the MMAC backplane.

5. Secure the module to the MMAC chassis by tightening the knurled

knobs. If you do not tighten the knurled knobs, vibration can cause the
module to lose contact with the backplane and disrupt your network.

6. Replace Security Bars on MMAC chassis.

at your own risk.

2.5.1 Connecting a Console Terminal

In order to access the ROM Monitor and boot the CSMIM-T1 for the first
time, you will need to connect a terminal to the Console Port. Please use
the adapters supplied in the accessory kit shipped with the module, as the
CSMIM-T1 Console port is a different configuration than other Console
ports. Follow the steps in this section to connect a console terminal to the
console port located on the front panel of the CSMIM-T1.

1. Connect the Console Terminal’s I/O connector to the RJ45 cable (the

accessory kit includes a cable) using a DB-25 DTE drop adapter.

2. Plug the RJ45 connector into the console port located on the front

panel of the CSMIM-T1.

3. When the connector clicks into place, the connection is secure.

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

4. Turn on the Console Terminal and 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.

CAUTION

2.6 POWER-UP AND TEST

1. Apply power (or insert into MMAC). The CSMIM-T1 now runs its

ROM-resident power-up diagnostics. The indicators momentarily
light and then turn off, except for the ON LINE LED and some status
LEDs.

If the diagnostics complete successfully, the CSMIM-T1 either enters
SET UP Mode and waits for configuration data to be entered, or boots
its operational image from Flash.

You can enter configuration information through a terminal
connected to the console port. The ROM monitor prompt (
appears on the terminal.

If the ATTN and the STAT LEDs are flashing together, there is a
CSMIM-T1 hardware failure. Contact Technical Support.

If the ATTN LED is flashing, there is a network or network interface
failure. An error message will display on the console.

If a network or network interface failure occurs, typing q accesses the
ROM Monitor prompt. Check the network connection, and then see
the net command in Chapter 3.

2-10 CSMIM-T1 Hardware Installation Guide

Auto-initializing the ROMs

2.7 AUTO-INITIALIZING THE ROMS

The CSMIM-T1 is distributed without an IP address or preferred load
host (UNIX/IP or MOP) defined in ROM. When the device is booted, the
CSMIM-T1 attempts to auto-initialize its ROMs using BOO TP (bootstrap
protocol) and RARP (Reverse Address Resolution Protocol).

The CSMIM-T1 supports the BOOTP and RARP protocols. The ROMs
use these protocols to obtain boot information without requiring any
manual set up on the CSMIM-T1.

• 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 ROM invokes these methods of acquiring boot information when a
boot is initiated and the CSMIM-T1’s Internet Address is not initialized.
Under this condition, the CSMIM-T1 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 CSMIM-T1 attempts to load an image
by transmitting an IPX advertisement request for service and a MOP
multicast boot request. Although it will attempt to load an IPX image, the
module WILL NOT BOOT FROM IPX.

If all requests fail, the CSMIM-T1 will return to the ROM Monitor (if in
test mode) or continue the auto initializing procedure indefinitely (if in
normal mode).

CSMIM-T1 Hardware Installation Guide 2-11

Chapter 2: INSTALLING THE CSMIM-T1

2.7.1 BOOTP

For a successful BOOTP retrie val, a bootpd must be running on a host on
the same network as the CSMIM-T1 and must have the appropriate
information in the bootptab file. The CSMIM-T1’s BOOTP
implementation adheres to rfc 951, rfc1048, and rfc1084. Below is a
sample bootptab file entry used to initialize the CSMIM-T1 named
terminator.

csmimt1default:\

: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=remoteannexdefault:

In the previous example:

• sm is the subnet mask

• gw is the load/ dump gateway address.

• vm is the Vendor Magic Cookie

• ht is host type (1=Ethernet)

• ha is the CSMIM-T1’s hardware address (Ethernet Address)

• ip is the CSMIM-T1’s Internet Protocol Address

When the CSMIM-T1 receives a BOOTP response with the sm, gw, and
ip set, it sets the respective parameters: subnet_mask,

load_dump_gateway, and inet_addr. Set vm to auto. This indicates that
bootpd should respond to the client (CSMIM-T1 in this case) with

whatever format the client requests; the CSMIM-T1 (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.

NOTE

2-12 CSMIM-T1 Hardware Installation Guide

The bootpd must be running on the CSMIM-T1’s preferred
load host.

Software Installation Procedures

2.7.2 RARP

If the CSMIM-T1 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
CSMIM-T1 and the host’s ARP table must be initialized with the
CSMIM-T1’s Internet and Ethernet addresses (see the arp man page,
arp -s).

The only boot information that RARP provides is the CSMIM-T1’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 CSMIM-T1 its boot information must be running on
the same network because the CSMIM-T1 only broadcasts BOOTP and
RARP queries.

If BOOTP and RARP fail, the CSMIM-T1 transmits an IPX
advertisement Request for Service and a MOP Multicast boot request.

If all requests fail, the CSMIM-T1 returns to the ROM monitor (if in test
mode) or continues the auto initializing procedure indefinitely (if in
normal mode).

2.8 SOFTWARE INSTALLATION PROCEDURES

Install the operational code on a UNIX host before loading it on a
CSMIM-T1. Please note that although the CSMIM-T1 will run on a
Novell system, it will not boot from Novell. The UNIX Installation Notes
describe how to install software on a UNIX host, as well as a non-UNIX
host. The CSMIM-T1 may also be booted from software loaded on
another CSMIM-T1 containing Flash, or from its own Flash memory (see
Section 2.7.2, Self Booting the CSMIM-T1).

When loading the CSMIM-T1 software for the first time, use the ROM
Monitor commands.

CSMIM-T1 Hardware Installation Guide 2-13

Chapter 2: INSTALLING THE CSMIM-T1

If you are loading software for the first time on a new unit, it is
not necessary to erase the EEPROM. To do so will erase the

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 CSMIM-T1
is in SETUP mode. Pressing the SETUP switch within 3 seconds of
powering up puts the CSMIM-T1 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 CSMIM-T1; 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
CSMIM-T1’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
CSMIM-T1 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 ROM 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 CSMIM-T1 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 CSMIM-T1’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.

CSMIM-T1 Hardware Installation Guide 3-3

Chapter 3: ROM Monitor Commands

The addr command display looks like this:

monitor:: addr

Enter Internet address [<uninitialized>]:: 192.9.200.214

Internet address: 192.9.200.214

Enter Subnet mask [255.255.0.0]::

Enter Broadcast address [0.0.0.0]:: 192.9.200.0

Broadcast address: 192.9.200.0

Enter Preferred Load Host address [<any host>]:: 192.9.200.88

Preferred Load Host address: 192.9.200.88

Enter Preferred Dump Host address [0.0.0.0]:: 192.9.200.88

Preferred Dump Host address: 192.9.200.88

Enter Load/Dump Gateway address [<uninitialized>]:: 192.9.200.

Load/Dump Gateway address: 192.9.200.88

Select type of IP packet encapsulation (ieee802/ethernet)
[<ethernet>]::

Load Broadcast Y/N [Y]::

The addr -d command display looks like this:

monitor:: addr -d
Ethernet address (hex): 00-80-2D-00-C6-1E
Internet address: 192.9.200.214
Subnet mask: 255.255.0.0
Broadcast address: 192.9.200.0
Preferred Load Host address: 192.9.200.88

Preferred Dump Host address: 192.9.200.88

Load/Dump Gateway address: 192.9.200.10
Type of IP packet encapsulation: <ethernet>
Load Broadcast: Y

The CSMIM-T1 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 CSMIM-T1
from a UNIX load host. If you do not define an IP address for the Remote
Annex, it will attempt to learn the address using BOOTP or RARP. If you

3-4 CSMIM-T1 Hardware Installation Guide

Commands

do not define a subnet mask, the CSMIM-T1 uses the generic mask for
the specified IP address.

The Remote Annex tries to boot from a preferred UNIX load host. If you
do not define a preferred load host, the CSMIM-T1 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 CSMIM-T1 uses the broadcast address parameter when loading a
file. If this parameter contains a specific address (for example,

132.245.6.255), the CSMIM-T1 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 CSMIM-T1 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.

NOTE

Do not change this parameter unless you know absolutely that
your Ethernet does 802.2/802.3 IP packet encapsulation. An
incorrect IP encapsulation type prevents your Remote Annex
from booting.

3.2.2 boot

The boot command requests the loading of appropriate CSMIM-T1
operating software from the preferred load host. The command syntax is:

boot [–lv | filename]

CSMIM-T1 Hardware Installation Guide 3-5

Chapter 3: ROM Monitor Commands

NOTES

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

Annex 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 CSMIM-T1’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
CSMIM-T1, boot requests the default file oper.56.enet. You can also
enter a file name using the image command.

The Remote Anne x boots from the defined preferred load host (UNIX/IP,
Novell/IPX, or VAX VMS/MOP). If the preferred load host is not defined
or does not respond, the CSMIM-T1 broadcasts on the Ethernet and loads
from the first host that responds.

To initiate loading, the CSMIM-T1 sends a load request message to the
selected host. After receiving a response, the CSMIM-T1 loads its
operational code to RAM memory . When loading is complete, it transfers
control to the newly-loaded program. The CSMIM-T1 displays a symbol
on the console for each data block received during the boot.

When the CSMIM-T1 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.

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 Annex indicating a gross problem with the Ethernet
connection (if this symbol appears in your boot command display , contact
technical support).

3-6 CSMIM-T1 Hardware Installation Guide

Commands

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

The console-baud command changes the console port’s baud rate. Thus,
the console port can interface with any modem to which it is connected.
When the baud rate is entered as auto, the CSMIM-T1 detects the baud
rate of the incoming line and adjusts its baud rate accordingly. This
command provides support for remote troubleshooting. The command
syntax is:

console-baud

The command display looks like this:

monitor:: console-baud

Remote Diagnostic Test Mode
In order to use the remote diagnostic functionality, you

must first connect a modem to the console port of the

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 CSMIM-T1
that corresponds to the port to be tested.

NOTE

When invoked, the command displays a menu of options.

Do not run the ports command for a port to which a device is
connected. The test will transmit data to the device and toggle
its control lines.

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 CSMIM-T1 will use for loading
and dumping. The default, net, uses the LAN interface. The list can
contain up to four interfaces. If the CSMIM-T1 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.

CSMIM-T1 Hardware 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.

NOTE

The CSMIM-T1 can slip boot over any port except Port 1.

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.

T-1 Commands

T1_loopback

The superuser T1_loopback command places the T-1 engine into loopback
mode. None of the loopback conditions persist through a power down or
reboot. A major consideration to those using the T-1 service must be made
before using this command since it will completely disrupt the T-1
service. To switch between two different types of loopback, the first
loopback must be cancelled before specifying the second loopback.

The syntax for the

T1_loopback command is:

T1_loopback [ none | line | payload | local ]

Table 4-5 describes the arguments for T1_loopback.

Table 4-5 Arguments for the T1_Loopback Command

Argument Description

None No loopback. This is the default. If the T1_loopback

command is initiated with no parameters, then none is
assumed. It cancels any user specified loopbacks.

Line Line loopback provides the network a means to test the

T-1 circuit for single ended fault isolation. The line
loopback regenerates the DS1 signal and does not
correct bipolar violations.

Payload Payload loopback is used to pro vide a loopback toward

the network. The data portion of the DS0 is looped
back.

Local Local loopback will loop back the data from the

customer side of both the T1 Network Interf ace and the
T1 Drop/Insert Interface.
Please Note: Network direction loopbacks in most
cases can be initiated by the Telco. The front panel Test
indicator illuminates when the T-1 is in loopback.

4-12 CSMIM-T1 Hardware Installation Guide

Set T-1 Parameters Example

tni_ones_density

This T-1 parameter is used to defeat the CSMIM-T1 ones density monitor.
The T-1 engine has a built in ones density monitor that will provide the
network with the correct number of one pulses. The ones density monitor
does the following:

1. The monitor does not allow the CSMIM-T1 to transmit more than

fifteen consecutive zeros.

2. The monitor ensures that the CSMIM-T1 has at least N ones in every

done is show the T-1 info screen, set the T-1 bypass to N allowing the T-1
line to interface with the module, change the loop start setting to wink
start, and reset the software at the appropriate times. This is an actual
example of how to make the T-1 module functional.

These LEDs indicate the number of modems installed
(8, 16, or 24). An indicator is green if all the modems
in its group are good. An indicator is amber if one
modem in its group is bad.

The CSMIM-T1 has three status indicators for each
modem port (1 through 24):
CD - Data Carrier Detect is a green LED and is on
when the carrier has been detected on the telephone
line on the corresponding modem.
TX - Transmit Data is a green LED that flashes to
indicate the corresponding modem is transmitting
data.
RX - Receive Data is a green LED that flashes to
indicate the corresponding modem is receiving data.

T1 Network Interface is looped back. Loopback tests
are activated either locally by the user or by the
telephone company.
SYNC - GREEN SYNC indicator is ON when the T1
engine is properly synchronized with the received
network signal and is receiving proper framing
information.
LOS - RED LOS indicator is ON when the T1 engine
is detecting no signal (pulses) on the network
interface receiver. When a LOS condition exists, the
T1 engine transmits unframed all one (AIS) to the
network.

CSMIM-T1 Hardware Installation Guide 5-3

Chapter 5: Troubleshooting Procedures

During power-up and booting, it is more difficult to diagnose problems
because they can originate in the CSMIM-T1, the network, or the load
server host. However, the LEDs provide both a progress report and an
error display to assist you in troubleshooting.

If an error occurs, save the status of these LEDs. Technical

NOTE

support personnel can use this information to diagnose
problems.

5.2 POWER-UP AND BOOT PROCEDURES

The CSMIM-T1 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 button on the front
panel puts the CSMIM-T1 into SET UP mode. When the CSMIM-T1 is in
SET UP mode, the SET UP LED lights.

During the CSMIM-T1 power-up and boot sequence, the CSMIM-T1
runs a set of diagnostics. The system LEDs display the diagnostics’ status.
The CSMIM-T1 stops when it detects one of two error conditions (see
Table 5-2). The pattern of the system LEDs identifies the error condition.

5.2.1 Normal Mode CSMIM-T1 Diagnostics

Following power-up or reset, the CSMIM-T1 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.

diagnostics. These diagnostics test internal hardware functions. If a test
fails, the ATTN and STAT LEDs flash and an error message is displayed
on the console port. The TRAF indicator flashes during the power-up
self-tests. After the self-tests complete, only the STAT and Ethernet
channel indicator remain on.

5.3 BOOT FAILURES

The procedures for troubleshooting a power-up failure established that

• The hardware is functional.

• The Ethernet interface is functional.

• The CSMIM-T1 can communicate with the Ethernet.

If the CSMIM-T1 still is not booted, you must pinpoint the problem. The
boot error report can help in this process.

The CSMIM-T1generates 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 CSMIM-T1 is not configured properly.

• The load server host is not responding.

CSMIM-T1 Hardware Installation Guide 5-9

Chapter 5: Troubleshooting Procedures

The CSMIM-T1 requests a boot image from a pre-defined load host or by
broadcasting a boot request. When a host responds, the CSMIM-T1 loads
its operational image.

The CSMIM-T1 requires setting certain configuration parameters. Enter
these parameters using the 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
CSMIM-T1 timed out while waiting for a response to its boot request; if
this field is empty, check the CSMIM-T1’s configuration parameters.

5.3.1 Boot Error Report

If an error occurs, a CSMIM-T1 boot error report is generated only if the
CSMIM-T1 has opened the boot file. The report is displayed using 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, predefined

NOTE

TFTP error codes.

The CSMIM-T1 generates a boot error report for the Internet address
from which it tried, and failed, to boot. T able 5-7 contains a description of
the Errors from the Last Read Request; and Table 5-6 contains a
description of the Errors from Last ERPC Layer Invocation.

5-10 CSMIM-T1 Hardware 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 (see Table 5-6). The report does not list errors that
occurred during any other Read Request (see Table 5-7) or during the
Open Request (see Table 5-8).

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.

Table 5-6 Errors from Last ERPC Layer Invocation

5.3.2 Correcting CSMIM-T1 Parameters

The following parameters must accurately reflect both the CSMIM-T1
and the network environment in which it operates.

Verify the CSMIM-T1’s IP 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 have 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.

You can use the defaults for the name of the image file containing the
CSMIM-T1’s software and the address of the preferred load server host.
If the value for the image name is incorrect, the CSMIM-T1 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
CSMIM-T1 has to broadcast for a host. Correct the load host’s address
using the addr command.

Confirm that the CSMIM-T1 boot parameters are correct by using the
appropriate ROM Monitor commands. Modify any boot parameters that
are incorrect or missing. Boot the CSMIM-T1 either by entering the boot
command at the console, or by holding down the

SET UP button until the

STAT LED blinks rapidly, and then releasing.

CSMIM-T1 Hardware Installation Guide 5-13

Chapter 5: Troubleshooting Procedures

5.3.2.1 Load Server Host Not Responding

The CSMIM-T1 can boot from one of the following hosts acting as a load
server host:

• A UNIX host on the network

• Another CSMIM-T1

• A VAX VMS load server host

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

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

5.3.2.2 UNIX Host on the LAN

When troubleshooting a UNIX host on the LAN, make sure that:

• The host is booted and functioning properly.

• The host can communicate with other network nodes using standard

UNIX networking features and utilities.

• All CSMIM-T1 software is installed properly on the host. See the

Software Installation Notes that come with the CSMIM-T1 software
release.

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

to the CSMIM-T1, is running.

In test mode, both the CSMIM-T1 and erpcd on the load server host
display boot progress reports. The CSMIM-T1 displays its reports on the
console; erpcd displays its reports on the UNIX terminal that invokes test
mode. To view the test reports, do the following:

1. 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 –D5

2. To place the CSMIM-T1 into test mode, hold down the SET UP button

for 3 seconds. (This resets the module, so warn users before you do it.)
Then enter:

Console monitor:: boot -v

5-14 CSMIM-T1 Hardware Installation Guide

BOOT Failures

When the CSMIM-T1 boots in test mode, the console displays the load
server host’ s Internet address, and indicates whether it recei ves 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 ve response.
If any CSMIM-T1-related files are missing or cannot be installed, contact
technical support (see Getting Help section in Preface).

A PC host running the UNIX operating system has the erpcd daemon
(provided with the distribution and installed in /usr/annex) running in the
background on the PC. Set the CSMIM-T1 and the erpcd on the load host
into test mode:

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

and restart it using the –D option:

# /usr/annex/erpcd -D5

2. On the CSMIM-T1, hold down the SET UP button for 3 seconds to

enter the SET UP mode. Then enter:

monitor:: boot -v

5.3.2.3 Another CSMIM-T1

When troubleshooting a CSMIM-T1 configured as a load server host:

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

and running.

2. Communicate with the unit on the Ethernet using the superuser CLI

ping command.

3. Verify the unit’s configuration using na.

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

A CSMIM-T1 that has been reconfigured as a load server host, but not
rebooted, cannot boot another CSMIM-T1 on the network. Rebooting the
CSMIM-T1 load server host ensures that the parameters are set.

5.3.2.4 VAX VMS Load Host on the LAN

If the installation was successful and the NCP CIRCUIT SERVICE is
enabled, but the CSMIM-T1 still fails to boot, performing the following
steps may locate your problem:

1. Make sure that the file CSMIM-T1 OPER_46_ENET.SYS is in the

directory MOM$LOAD and the file protection allows reading.

2. Enter the system manager account and enable console logging to see
