Restrictions
This product is used in a combination with the optional expansion adapter. The following restrictions
apply to the situation when the expansion adapter is connected to the expansion chassis.
This product has restrictions on the types of PCs and boards that can be used.
Be sure to check the following restrictions before use.
< Restrictions of PC>
This product uses the PCI-to-PCI Bridge to extend the bus.
The PCI boards plugged in PCI slots in this product are recognized if the PCI-to-PCI bridge is
recognized by the BIOS in the PC used. Ask the PC vendor for whether the BIOS recognizes the
PCI-to-PCI bridge.
< Restrictions on transfer rate >
When the expansion chassis accommodates a board that performs high-speed transfer such as bus
mastering, the overall transfer rate may be lower than that of PCI bus slots in the main unit of a desktop
PC.
This is caused by bus extension by the PCI-to-PCI Bridge.
The transfer rate may vary with the system configuration and the type of the PC.
< Restrictions of PCI board>
None of the following boards can be plugged into any expansion slot in this product.
-
Video display board (VGA board)
-
Board to connect a PCI bus expansion chassis
-
Board explicitly stated not to be used with the PCI-to-PCI Bridge
-
Some boards, even PCI-compliant ones, may not work depending on their specifications
