Installing and Removing Hardware
Expansion cards 130
CAUTION: Before installing the PCI option card, check that
the form of the connection part of an option card and the
connector form of a PCI slot are adapted.
The following composition is recommended:
- PCI-1, 2, 3 and 4 slot ... PCI-X : 64 bit / 100MHz
If the other PCI option card is installed, the performance of
this server and the PCI option card may fall.
NOTE: The PCI-1 and PCI-2 slots operate together in the
same operation mode. (If you use two PCI option cards that
have different supported operation modes at the same time,
then the system operates at the lower performance level of
the operation modes on the two PCI option cards.)
The PCI-3 and PCI-4 slots operate together in the same
operation mode. (If you use two PCI option cards that have
different supported operation modes at the same time, then
the system operates at the lower performance level of the
operation modes on the two PCI option cards.)
