Inserting the adapter in a PCI Express slot
The SFN8041 QSFP+ single-port adapter is a half-height, half-length, 8-lane PCIe 3.1
form factor adapter.
NOTE:
The Solarflare SFN8041 server adapter requires an 8-lane or 16-lane
PCI Express slot. For maximum performance the adapter should be installed in a
PCIe 3.1 or PCIe 3.0 slot, but is compatible with PCIe 2.0 or PCIe 1.x.
Shut down the server and unplug it from its power source. Remove the server cover
to access the PCI Express slots in the server. Locate an 8-lane or 16-lane PCI Express
slot (refer to the server manual if necessary) and insert the Solarflare server adapter.
Secure the adapter bracket in the slot.
CAUTION:
The SFN8041 adapter must have sufficient air flow cooling – during
normal operation the minimum air flow required is 300 LFM.
Server cooling fans
must be fully operative to prevent damage to the adapter.
