IBM SY27-0345-06 - Manual (Page 23)

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/221
