MAP1245 Finding FRUs by using location codes

How to convert a location code to the storage facility location that contains the FRU or function.

In most cases, any FRU listed in a serviceable event includes a location code. Cables are a special case because they do not have their own location code. Cables that can be identified as failing by the microcode use the location of the FRU connectors they connect to. This means that those cables have two location codes, one for each end of the cable. For a Y cable in the power system, there will be three location codes. Cables that are not reported directly by the microcode are determined by guided isolation procedures.

MAP1245 Section-1

  1. Location codes have two parts:
    • The "MTMS" (machine type, model, serial number) of the rack or enclosure within the rack
    • The physical location within the rack or enclosure
    Example of location code: 2107.D02.1300177-P1-C2-T3
    • The MTMS(machine type, model, serial number):
      • 2107.D02 = storage enclosure (machine type/model)
      • 1300177 = storage enclosure serial number (visible on the bar code label)
    • The physical location:
      • P1- = Planar 1
      • C2- = FCIC card 2 (right FCIC in storage enclosure)
      • T3 = FC-AL cable connector (third FC-AL cable connector from left on FCIC card)
  2. To convert the MTMS or location code to the FRU type or enclosure type, select the following conditions that apply:
    • For rack models 983, use table Table 1
    • For rack models 98x (not 983), 8xE, use Table 2
    • For rack models 961, 96E, use Table 3
    • For rack models 951, 95E, use Table 4
    • For rack models 941, 94E, use Table 5
Note: Machine type 958n is not shown in Table 1. Machine types 533n and 958n are not shown in Table 2. To look up entries for machine types 533n and 958n, use the entry for the associated model under machine type 283n. For example, to look up an entry for 5331.986.ssssss0, use the entry for 2831.986.ssssss0.
