Chapter 3. Blade server hardware configuration 

Only one PEU3e can be attached to the blade server. When a PEU3e is added to a blade 
server along with the Storage I/O Expansion (SIO), only slot 1 of the PEU3e will be functional. 
See 3.18, “Expansion blades” on page 358, for a discussion of all expansion units and the 
supported combinations for each blade server type. Table 3-92 on page 358 lists the blade 
servers that support the attachment of the PEU3e.

For the list of PCI Express adapters that are supported in the two full-length slots of the 
PEU3e, see ServerProven at:

http://www.ibm.com/servers/eserver/serverproven/compat/us/peu/43W4391.html

 

There are no PCI-X or PCI Express sockets on the PEU3e that are suitable for BladeCenter 
expansion cards such as the StFF, CFFh, or CFFv expansion cards. Therefore, if the PEU3e 
is attached to a blade server, then it is not possible to also install a CFFh I/O adapter.

Figure 3-65 on page 370 shows the internal circuitry of the PEU3e.

Note: Using PCI Express adapters that require more than 25W requires special testing 
and support to be completed. The cable or cables used to connect to the 12 volt 
connectors on the PEU3e are only available if this testing is completed successfully.
