Locations

Learn how to locate field replaceable units (FRUs) by using logical and physical location codes.

Note: The known logical location codes for this unit are listed next to the corresponding physical location in the following information. If you are working with a logical location code for this unit and it is not listed in the following information, contact your next level of support.

The following diagrams show field replaceable unit (FRU) layout in the expansion unit. Use these diagrams with the following tables.

Note: Some units may have labels that designate location codes other than those shown in the following illustrations and tables. If that is the case, use the location codes shown in the following illustrations and tables.

The following table gives the components available for callout on the expansion units, and matches those components with the FRU containing the component. For part numbers associated with failing components, see 0595, 5095, and 7311-D20 system parts.

Notes:
  1. J11 is an RPO connection, J14 is an uninterruptible power supply connector, J15 is an SPCN 1 connector, and J16 is an SPCN 2 connector.
  2. Multi-adapter bridge domains are labeled PCI Bridge Set inside the expansion unit.
  3. The following table provides information necessary to identify the IOP to which an IOA is assigned.
    • The left column indicates the domain in which IOA assignment is allowed.
    • The right column is used to determine the IOP to which an IOA is assigned.
    • The first position in the list must be an IOP. The remaining positions may be IOPs or IOAs. IOAs are assigned to the first IOP located to their left in the list. Although IOAs can be manually reassigned using SST/DST, the IOA assignments return to the default order after each IPL.
