Use Cases
The PCI-AD-X16HE-PS-MD card may be used as both a Host card and a
Target card. A Host and Target card can be used as a pair or the Host card
can be used with a compliant Target device. The supported use cases and
the DIP switch settings are summarized in Table 4: Use Case DIP switch
settings.
Please use the table to identify the correct DIP switch settings.
Use Case A - 1 Host – Single Expansion Configuration
The Host system has a PCI-AD-X16HE-PS-MD adapter configured for Host
operation and a direct x4, x8 or x16 link to a PCI-AD-X16HE-PS-MD
configured for Target operation.
Connecting the cables for single expansion, x16 link
To establish an x16 link, a given port number should be connected to the same port number on the other card.
Always connect a cable from Port #x to Port #x
