connections, the same cable-ports (i.e. port 1 to port 1, port 2 to port 2 through port 4) should be used on both host and target for
each individual cable, to ensure that the cards properly link up as x8 or x16.
Cable stain relief
Strain-relief on the PCIe cables are important to protect the PCIe card from fatigue loading and damages. The cable should be
mechanically connected to the rack or cabinet. This is especially important for long heavy cables and cables going between cabinets
and racks.
Supported cable lengths
The MXH932 supports both copper and active optical PCIe cables (AOC). Maximum lengths between two MXH932 cards can be
found in Table 1 below. The maximum distance may change when connecting to other PCIe products.

guides.
Step 7 - Verify Installation & LEDs
The MXH932 comes with 4 bi-color LEDs which show the corresponding cable port status according to Table 2: LED below.
The LEDs are visible through cut-outs in the PCIe bracket on each side of the cable connector block.
