Assembly Instructions
1. For each multi-host configuration option, connect PCB000981 (server side extender with
repeater) into the slot available on the server.
2. Connect PCB000981 with PCB000980 Multi-Host EVB using QSFP cables MT-PCI-HS-
QSFP_REV.A1. Connect the server side extender with repeater to the Multi-Host EVB
according to the colored connectivity scheme shown in
Section 3.1, “Two Hosts Configura-
and
Section 3.2, “Four Hosts Configuration”.
3. The Multi-Host EVB can also share power rails from four different servers. In order to test
this feature, connect the 12V and 3.3V power rails from PCB000981 to PCB000980 using the
power cable MT90C32-001_REV.A1.
4. For comfortable work without overload of power cables, it is possible to use the power supply
included in the kit. Connect the power supply to the electricity plug from one end and connect
it to the adapter harness on the other end. Then connect the harness to J1024 connector on the
EVB.
5. When power of the EVB is supplied from only one host, the maximum power, may exceed
the 25W per slot (according to the PCIe spec). Instead of connecting to only one host, it is
best to connect at least two power sources (i.e. to two hosts) for better power distribution
between the hosts.
