Configuration Rules 2-13
Each AlphaServer GS140 system may have a DWLPB PCI card cage with either
a KFE70 adapter (standard I/O) or a KFE72-EA adapter (for graphics support)
installed. This is only necessary if you wish to have the floppy drive installed
near the front panel switches in the main cabinet. The I/O hose for this PCI
must be connected to the I/O module in TLSB slot 8.
An additional DWLPB PCI card cage must be installed in the system for each
secondary partition. These DWLPBs hold the KFE72-DA adapters needed for
the additional serial console terminals for secondary partitions.
Figure 2–6 shows three DWLPBs, one with a KFE70. If used, the KFE70 must
be in a DWLPB connected to the I/O module in slot 8 of the TLSB bus, as
shown. The two other DWLPBs with KFE72-DAs for secondary partitions may
be connected to any hose on any I/O module assigned to the partition. See
Figure 2–7 for hose numbers for the various I/O slots.
The DWLPA/DWLPB PCI PIU Installation Guide tells how to install DWLPB
PCI card cages.
