MXH932 High Level Specification
The MXH932 is a low profile, half-length PCIe adapter that can be configured as a Transparent Host Adapter card or a Target
adapter card. Once installed in any server’s or PC’s PCI Express compliant slot, a
MXH932 can connect to another MXH932
configured for Transparent Target operation or any target device compliant to the PCI Express External Cabling Specification 4.0.
The MXH932 configured as a Transparent Target card can be installed in a PCI Express compliant expansion upstream slot. Please
contact Dolphin for a list of compliant expansion chassis. The MXH932 supports PCIe Gen1, Gen2, Gen3 and Gen4 speeds and x1,
x2, x4, x8 and x16 link-widths. The card will operate at the highest common speed shared between the slot and the card (Gen4)
and the widest common link-width (x16).
