Indicators on the IBM 2210

The IBM 2210 has green and amber light-emitting diodes (LEDs) that indicate the

status of the system and of individual ports.

 Green indicates normal operation.  Amber indicates the presence of a problem.

The indicators appear on the side of the IBM 2210 containing the ports and are

duplicated on the side that is opposite the ports. This arrangement allows the cus-

tomer to use either side as the “front.”

Figure 1-12 shows the indicators that appear on the side of the IBM 2210 con-

taining the ports. Note that this illustration shows Model 12T; the port LEDs on

different models are tailored to the particular ports supported.

Figure 1-12. LEDs on Port Side of Models 12T

Figure 1-13 shows the indicators on the side of the IBM 2210 that is opposite the

ports.

Chapter 2. Problem Determination

Use the maintenance analysis procedures (MAPs) in this chapter when the IBM 2210 is not operating normally.

Before using the MAPs, read these notes:

 Review the diagnostic instructions in Chapter 3, “Diagnostics” on page 3-1.  When a MAP instructs you to replace a field-replaceable unit (FRU), see

Chapter 4, “Removal and Replacement Procedures” on page 4-1.

 Chapter 1, “Models, Indicators, and FRUs” contains reference material and

illustrations that you may wish to consult while using the MAPs.

| Note: Box images that support the DIALs Server Function require certain PROM | Load/Dump Program versions. Models 12x require PROM Load/Dump revision | level 1.6 or higher. If you have an earlier version you must order a PROM | upgrade. Models x4x require revision level 2.20 or higher. The code is available on | the Web at: http://www.networking.ibm.com/support/downloads/221ð

Chapter 2. Problem Determination 2-3

MAP 0120: LEDs Indicate a Fault

Diagnose a problem reported by the LEDs in the following sequence:

1. Use Table 2-2 to diagnose the error conditions reported by the system LEDs, because these take precedence over the port LEDs. (For example, if the system amber LED is on, it does not matter which port LEDs are on.)

Note: Throughout this manual, the term

system LEDs

refers to the green (OK)

and amber LEDs on the left side of the IBM 2210. This table is valid after power-on or Extended POST completes.

2. If the system LEDs appear to indicate no problem, go to Step 001 in the MAP.

Chapter 3. Diagnostics

The IBM 2210 diagnostic programs test the system hardware and detect hardware problems. The diagnostic routines include three types of tests:

 Power-on self-test (POST)  Extended POST  Menu-driven diagnostics

The diagnostic package includes service aids that may be used to display the diagnostic logs and to view the vital product data (VPD).

| Note: When using a locally attached terminal to run the IBM 2210 diagnostic pro| grams, the service port line speed must be set to 9600 bps. This setting is a con| stant and cannot be changed.

Diagnosing Hardware Problems

Running the diagnostics requires complete control of the IBM 2210. Attention: Do not shut down the IBM 2210 without the knowledge and permission

of the customer. Contact the customer’s system administrator before shutdown.

Power-On Self-Test

The power-on self-test (POST) provides a basic confidence test of the IBM 2210 processor, memory, and interfaces.

Starting the POST

The POST runs automatically whenever the IBM 2210 is powered on. If the machine is already powered on and you want to execute the POST:

1 Stop the IBM 2210 by unplugging the power cord from the power outlet. 2 Plug the IBM 2210 into the power outlet. 3 If the system green (OK) LED is off and the system amber LED is on after

Extended POST

It is possible to run an extended POST that does not require attachment of a terminal. Extended POST allows you to test memory more extensively than normal POST. Follow these steps to run diagnostics without a terminal:

about 2 minutes, run the Extended POST.

1 Stop the IBM 2210 by unplugging the power cord from the power outlet. 2 Disconnect the cables from the ports. 3 Plug the IBM 2210 into the power outlet. Wait for a port green LED to flash

(2 to 3 seconds) and then push the reset button once. (See Figure 1-14 on page 1-5.)

 Copyright IBM Corp. 1994, 1998 3-1

4 If the Extended POST has completed successfully:

 The green LEDs for the system (OK) and for any port with wrap plugs

will be on.

 The port amber LEDs will be off (or blinking if no wrap plug is installed).

For the 12x models, the system (OK) green LED blinking with the system amber LED on indicates that the service port external wrap test has failed.

5 To run the extended POST again, press the reset button after 2 minutes. 6 To end extended POST, power off the IBM 2210 by unplugging the power

cord from the power outlet.

7 Be sure to remove any wrap plugs from the IBM 2210 before applying power

to reload the router. Do not leave wrap plugs on unused ports.

| Above references to wrap plugs do not apply if an internal wrap is performed during | extended POST. An internal wrap is performed if the following levels of boot code | are installed:

|  IBM 2210 12x models if you have the boot code level 1.62 or higher. |  IBM 2210 models 1S4, 1S8, 1U4, and 1U8 if you have the boot code level 1.32

| or higher. |  IBM 2210 x4x models if you have the boot code level 2.40 or higher.

Operational Diagnostics

To run the menu-driven operational diagnostics, attach an ASCII terminal to the IBM 2210. If no terminal is available, run the Extended POST, as described in “Extended POST” on page 3-1.

If an ASCII terminal is already attached to the IBM 2210, continue with “Running the Diagnostics.” Otherwise, go to Appendix A, “Access Methods and Attaching an ASCII Terminal” on page A-1 for instructions.

Note: Because running the diagnostics requires complete control of the IBM 2210, be sure to notify the customer’s system administrator before shutdown.

Running the Diagnostics

You can execute the diagnostics:

 Immediately after attaching an ASCII terminal  When an ASCII terminal is already attached and the router user interface is in

operation.

Immediately After Attaching an ASCII Terminal.:

diately after attaching a terminal:

Appendix A. Access Methods and Attaching an ASCII Terminal

To run the menu-driven diagnostics, you must attach an ASCII terminal to the | service port of the IBM 2210. This chapter explains how to access the IBM 2210’s | operational and configuration software. The chapter also lists the ASCII terminals | that are supported and provides information about setup attributes.

Access Methods

| The IBM 2210 software must be configured as part of the installation process. | Therefore, you have to access the software in one of the following ways:

|  Locally through a null-modem adapter and serial cables supplied with this | product that are attached to the EIA-232 service port using an ASCII con| nection. See Figure A-1.

|  Remotely using dial-in (over telephone lines) through a modem attached to the | EIA-232 primary service port or the secondary service port, if installed. You can | also use an ASCII connection. The secondary service port can be either an | EIA-232 Service Port Feature or a 14.4 Kbps Modem Port Feature. See | Figure A-2 on page A-2 and Figure A-3 on page A-2.

| | Access Pro-

| Default IP | Physical Attachment| Line Protocol

| tocol

| Address | Service port + null modem

| Asynchronous

| ASCII terminal | Service port + external modem

| characters

| An ASCII connection requires an ASCII terminal or workstation running an ASCII | terminal emulator.

| Once the IBM 2210 is operational in the network, you can access the IBM 2210 by | Telnetting from a network-connected workstation. This workstation must be | attached to any of the IBM 2210’s IP-capable network interfaces. The network inter| face can be on a LAN adapter or WAN adapter because both support IP routing. | The Telnet workstation can be locally or remotely connected.

| Service Port Default Settings

| These are the default settings for the serial port: | Speed 9600 bps

| Parity None | Data Bits 8 | Stop Bits 1

| You can configure the service port speed for the following bit rates; however, the | speed must match the speed configured for the ASCII terminal. The IBM 2210 also | supports auto-baud.

| 300 | 1200 | 2400 | 4800 | 9600 | 19 200 | 38 400

| Modem Support

| Modem Requirements | The modem must be connected to the service port on the IBM 2210, use asynchro| nous operation, and be compatible with the Attention (AT) command set. A modem | connected to a 2210 service port must be configured with the following character| istics:

|  No echo |  Suppress results code |  Auto-answer

A-2 2210 Service and Maintenance

|  Hardware (RTS/CTS) flow control |  Modem DTE speed fixed to match 2210 service port speed (9600 recom| mended).

| Consult your modem documentation on how to configure and save these settings. | Remote Connection for Service

| To resolve a problem with your IBM 2210, IBM service personnel may request per| mission to establish a temporary, remote connection to the IBM 2210. In most situ| ations, the IBM service personnel will not be at a remote workstation that is | connected to your IP network. Consequently, remote access must be established | using a modem. Whenever you authorize IBM service personnel to establish such | a remote connection, you must:

|  Connect and configure the modem before the remote service session can begin |  Provide the service personnel with the telephone number of a modem con-

| nected to the service port of the target IBM 2210 or to a modem that is con| nected to the service port on an IBM 2210 that is on the same network as the | target IBM 2210

|  Provide service personnel with the password or other necessary information for | access to any security protection features

| Modem Settings | The following modems have been tested for use with the IBM 2210:

| IBM 7852, Model 400 | Zoom/FaxModem 56Kx | Atlas 33.6 External PC Data/Fax Modem

| For instructions on setting-up these and possibly other modems to operate with | your IBM 2210, see: http://www.networking.ibm.com/support/221ð

Attaching an ASCII Terminal to the Service Port

| | Attach an ASCII terminal or emulator (with the appropriate emulation software) to

| the service port to provide local or remote access to the IBM 2210 as shown in | Figure A-4 on page A-4.

Appendix A. Access Methods and Attaching an ASCII Terminal A-3

100-240VA

0.4-0.2A50/60H C

Figure A-4. Attaching an ASCII Terminal to the Service Port

| When locally attaching a terminal to the IBM 2210 service port, the speed (baud | rate) configured for the service port must match the speed of the connected ter| minal if the IBM 2210 has been configured to use a specific baud rate. If the IBM | 2210 is configured for auto-baud the IBM 2210 learns the ASCII terminal’s line | speed when the user types the terminal break key sequence and presses Enter. A | typical break key sequence for PC terminal emulators is Alt-B (refer to the terminal | emulator documentation). Most ASCII terminals have a Break key (often used in | conjunction with the Ctrl key).

| Note: When using a locally attached terminal to run the IBM 2210 diagnostic pro| grams, the service port line speed must be set to 9600 bps. This setting is a con| stant and cannot be changed.

| When connecting a IBM 2210 to a remote terminal by two modems connected by | telephone lines, you must follow these rules:

|  If the modems are running at a speed of 9600 or lower and they do

not

| support hardware compression, the IBM 2210 service port speed and the ter| minal speed must match the modems’ line speed.

|  If the modems are running hardware compression, the IBM 2210 service port | speed and the terminal speed should exceed the modems’ line speed.

Note: The IBM 2210 service port can be damaged by static electricity discharge. It is shipped with a plastic port cover to prevent such damage. Remove the plastic cover when you are attaching a terminal and store it in a safe place. When you disconnect the terminal, reinstall the plastic cover.
