IBM Serial I/O Expandable Adapters ship from the factory with the
power straps configured to provide power to the Port Modules via the
Host Bus Cable(s). Normally there is no need to reconfigure any of
the power straps.
If a PS-4 power supply is used, no power is drawn from the host
system for the port modules.
This appendix describes the following power defaults and optional
configurations for PCI Adapters:
•
The default (factory configured) power straps are set to obtain
power for Port Modules 1-4 (ports 1-64) from the host
computer backplane(i.e. the PCI Bus) and to obtain power for
Port Modules 5-8 (Ports 65-128) from the computer power
supply via J1.
•
The power strap connections can be configured to optionally
obtain power for Port Modules 1-8 (Ports 1-128) from the
host computer backplane (i.e. the PCI bus).
