Chapter 1: 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 device that comes with an Intel 80486

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

(ROM) contains firmware for performing power-up self-tests and loading operational code. A non-volatile EEPROM stores the configuration parameters.

The ROM Monitor is an interactive command interpreter that accesses the

ROM’s functions. ROM Monitor commands are issued through a terminal connected to the console port on the Micro-CS . Using the ROM Monitor commands, you can:

•

Modify and display a set of EEPROM parameters.

Execute interactive diagnostic tests.

Receive information and statistics for the hardware configuration and the network.

• Boot the Micro-CS manually.

The Micro-CS is a diskless device. It obtains operational code either over the network from a host running Micro Annex Communication Software

Version 9.2.6 or above, another Micro-CS configured as a load server, or from self-contained Flash Memory.

The Micro-CS has a watchdog timer that is reset by the software at regular intervals. The watchdog timer reboots the Micro-CS in the unlikely event of an internal software error. This feature allows the

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

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

It consists of a single daughter card, and can be user installed. The upgrade kit can be purchased separately from Cabletron as part number

CSM-V.34-UGK.

CHAPTER 2 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 CRT-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 ROM

Monitor mode by pressing the SETUP switch for at least three seconds, until the SETUP LED flashes indicating a reset. Release the switch and all the port LEDs will turn on then off. Press the SETUP switch again within 3 seconds after the PORT LEDs have turned off, and the SETUP

LED will be on indicating the Micro-CS is in setup mode. Once the

Micro-CS has successfully completed its start-up diagnostics, the ATTN

LED will turn on indicating ROM Monitor mode. Each subsequent depression of the SETUP switch will toggle the Micro-CS SETUP LED off and on. In order to return to Normal mode, the Micro-CS must be re-booted.

NOTE

The amber ATTN light is ON when the unit is in ROM Monitor 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.

CAUTION

The Micro-CS can incur damage if the cables conduct transients such as those induced by lightning strikes, etc.

Preferred Dump Host address: 0.0.0.0

Load/Dump Gateway address: <uninitialized>

Type of IP packet encapsulation: <ethernet>

Load Broadcast: Y

NOTE

You are prompted for the gateway address only if the internet 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.

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.

“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.

NOTE

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

Execute the erase command to clear the EEPROM. (See the erase command in Chapter 3.)

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.)

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).

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 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 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

NOTE

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 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]

NOTE

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

(Flash) is installed.

Typing the letter q or CONTROLC 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 defined 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 =

40 =

Transmission deferred because link was busy

Collision detected during interframe spacing

20 =

10 =

(SQE/Heartbeat detected)

Excessive collisions

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

ping

The ping command sends an Internet Control Message Protocol (ICMP) mandatory ECHO_REQUEST datagram to elicit an ICMP

ECHO_RESPONSE from a host or gateway. ECHO_REQUEST datagrams (pings) have an IP and ICMP header, followed by a structured time value and an arbitrary number of pad bytes that fill out the packet.

The syntax for this command is:

ping host_ip_address [data_size] [npackets]

The host_ip_address entry is the Internet address of the host or gateway from which you wish to elicit a response.

The optional data_size entry is the number of bytes sent in a datagram packet. The default value is 64 and the maximum value is 1024.

3-18 Micro-CS Installation Guide

Commands

The optional npackets entry is the number of packets to transmit. If you specify npackets, then you must also specify a data_size.

The ping command display looks something like this: monitor:: ping 132.245.33.69

PING 132.245.33.69: 64 data bytes

To exit out of ping either wait for npackets to be transmitted or, at any point, type q . The ping statistics display upon exit.

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 Micro-CS that corresponds to the port to be tested.

NOTE

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.

When invoked, the command displays a menu of options.

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

NOTE

The SELF 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

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

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.

Press the SETUP switch to put the Micro-CS into monitor mode.

Activity T2: Testing 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

NOTE

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

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

NOTE

TFTP error reporting complies with the standard, pre-defined

TFTP error codes.

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.

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.

ARP errors

Aborts rx’d

Table 4-5 Errors from Last Open Request

ERPC layer errors

Address Resolution Protocol (ARP) errors indicate that the Micro-CS is configured to boot from a specified host, but the host would not transmit its Ethernet address to the Micro-CS. Possibly, the Micro-CS configuration includes the wrong IP encapsulation.

See Errors from Last ERPC Layer Invocation below.

The host’s BFS transmitted an abort in response to the

Micro-CS’s Open Request. This often means that the requested file does not exist on that server. Run

erpcd -D on the host to obtain more information.

Aborts rx’d

Table 4-7 Errors from Last ERPC Layer Invocation

Msgs of wrong type

The Micro-CS sensed a hardware error during message transmission or reception. This error indicates a fault with the Micro-CS network interface. Use the net command to isolate the problem (see Chapter 3).

The Micro-CS received a message from an incorrect host. This indicates that the

Micro-CS received, and ignored, an unsolicited packet.

The Micro-CS never received a correctly formatted response from the correct host, or any response from any load server hosts.

The correct host sent a message to the

Micro-CS, but the message was not a correctly formatted response to the transmitted request.

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 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.

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 affirmative 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.

NOTE

Dump files are generated for use by technical support personnel only.

Table 4-8 Indicator States during a Dump

Activity

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.

Please note that although the hardware configuration of the FLASH card is the same for the Micro-CS, CSMIM2, and MODMIM, the image is not.

The Micro-CS uses “oper.52.enet” and the CSMIM2/MODMIM use

“oper.42.enet”. It is possible to use the FLASH card on either platform, but the image loaded must be the correct one for the application.

C-2 Micro-CS Installation Guide

Installation Procedure

C.4.2

Changing the Boot Method

Attach a VT-100 type console terminal to port 1. Set this terminal to

9600, no parity, 8 data, 1 stop.

Power-up the MicroMMAC with the Micro-CS installed. Immediately following the LED test (all turn on and then off), depress the SETUP switch on the Micro-CS using a thin tool and note that the SETUP indicator turns on.

After approximately one minute the console displays the monitor prompt (monitor::). At this prompt, enter:

seq <cr>

The console responds with the prompt

Enter interface sequence {net}::

At this prompt, enter:

self <cr>

Now check for a bootable image in the flash PROM. At the monitor prompt, enter:

image -d <cr>

The last line of the response should read:

SELF image name: “oper.52.enet”

If this name is missing, the Micro-CS did not find a bootable image in the newly-installed Flash PROM. Contact Technical Support for assistance.

At the monitor prompt, execute the boot command by entering:

boot <cr>

NOTE

In the unlikely event that you should ever have to return the

Micro-CS to Cabletron for repair, please remove and save the flash upgrade for use on the replacement board supplied by

Cabletron. If you are unable to remove the Flash, contact your

Cabletron Customer Support Representative so that they can document that the board was returned with the Flash still installed.

Connect the RJ45 cable from the EPIM-3PS (or the BRIM) to the J3 jack on the Micro-CS.

Check the alignment of the ports on the front panel.

Insert screws through holes in the Micro-CS to the standoffs in the

MicroMMAC and tighten.

Locate the mylar replacement faceplate for the MicroMMAC and

carefully attach it now.

TIP

The mylar faceplate for the MicroMMAC is very sticky. You may only have one chance to get it on right. It is easier if you start from the right side of the MicroMMAC and align the corners.

Ensure that the cover is in place before connecting the power cord.
