EAD-CE-EC
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.
EAD-CE-EC 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>
EAD-CE-EC uses the PCI-to-PCI Bridge to extend the bus by using the expansion chassis
ECH-PCI-CE-H2B.
The PCI boards plugged in PCI slots in the EAD-CE-EC 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 types of boards can be used in any expansion slot in the expansion chassis
connected to the EAD-CE-EC.
-
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
