SI_PHB: high-speed link PCI host bridge.
The HSL I/O bridge hardware in a base I/O tower or I/O expansion tower is
failing. Follow the procedure to identify the failing component to exchange.
1. If you are working from the Service Action Log and a card position is listed
with this FRU, then that is where the error is located, 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 280 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 item. Record the frame or tower type.
2. Use the system model, tower, expansion unit or machine type and the table
below to determine the service information for the failing component.
