Use Cases
The PXH822 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 6: 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 PXH822 adapter configured for Host operation and
a direct x4, x8 or x16 link to a PXH822 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
A failure connecting any of the cables will cause the link to re-train to x8 or x4.
