RMDEV
For use by authorized service providers.
A removable media power regulator or device in a migrated expansion tower may be failing.
See the RMDEV symbolic FRU in the Migrated Expansion Tower Problem Analysis, Repair and Parts
manual on the V5R1 Supplemental Manuals web site
for FRU isolation instructions.

SIADPCD: High Speed Link I/O bridge card.
If you are working on a Model 170, 250, 5xx, 6xx, or SBx, see the following for field replaceable unit
(FRU) isolation and repair.

The failing component is the HSL I/O bridge card in a system unit primary I/O unit (for Models 830, 840,
870, 890, SB2, and SB3), an FC 5074, FC 5078, FC 0578, FC 5079 (1.8m expansion tower) I/O
expansion tower, or the Integrated xSeries Adapter Card in an xSeries server.
1. If you are working from the Service Action Log and you know the frame ID where this failing
component is located, then continue with the next step in this procedure. Otherwise, record the bus
number value (BBBB) in word 7 of the SRC (see “Breaking down the SRC” on page 63 for help in
determining the bus number). Search for the bus number in HSM or the System Configuration Listing
to determine which frame or I/O tower contains the failing component.
