This tip is not software specific.
Workaround
The 4 GB Fibre Expansion Options in a BladeCenter HS40 (Type 8839) must be set to 1 GB or 2 GB.
Additional information
The amplifiers used on the BladeCenter HS40 (Type 8839) are unable to sustain consistent 4 GB connectivity. This is a design limitation of the Blade. The QLogic 4 GB Expansion Option part number 26R0884, documents this limitation. The data rate (QLogic) or the link speed (Emulex) needs to be set to either 1 GB or 2 GB in the adapter's BIOS configuration utility.
Access the adapter's BIOS configuration utility, by pressing CTRL-Q for QLogic or by pressing CTRL-E for Emulex, during POST .
