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.

Reset Button

The reset button, shown in Figure 1-14, works in this fashion:

 If you press it, you will reload the operational code.  If you press it within 10 seconds of powering on, you will start the Extended

POST. See “Extended POST” on page 3-1 for more information.

The reset button is recessed to prevent accidental activation. Use a pen or pencil to press it.

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

001

– Make sure that:

 The fan is clear of any obstructions.  The room temperature is within limits (5° to 41°C [50° to 104°F])

Did you find a problem? Yes No

002

Continue with Step 004.

003

Resolve the problem. Then, go to “MAP 0210: Verify Operation” on page 2-23.

004

Is the fan running? Yes No

005

Replace the fan. Then, go to “MAP 0210: Verify Operation” on page 2-23.

006

– Run the System Extended Diagnostics. For assistance, go to “Operational

Diagnostics” on page 3-2. If you are unable to resolve the problem, contact your next level of support.

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.
