3.18.5 PCI Express I/O Expansion Unit (PEU3e)
The PCI Express I/O Expansion Unit (PEU3e), part number 43W4391, attaches to supported
blade servers via a connector on the server motherboard. The PEU3e has two standard
full-length PCI Express slots that support the attachment of 2 full sized, 25W PCI Express
adapters. These two slots are PCI Express x16 slots mechanically, however they can only
operate at speeds up to x8. The PEU3e provides two power connectors that can be used to
provide 12V, via a cable, to PCI Express adapters that have external power connectors.
