I/O expansion options

The server supports up to four PCI Express slots with different riser cards installed into two riser sockets on the system planar (one riser socket supports installation of one riser card). The slot form factors are as follows:

• Slot 1: Full height, full length
• Slot 2: Low profile with standard bracket
• Slot 3: Full height, full length
• Slot 4: Full height, half length

Riser 1 supplies slots 1 and 2. Riser 2 supplies slots 3 and 4. Standard models have two riser cards installed that provide a total of four PCI Express 2.0 x8 slots (two PCI Express x8 Gen 2 slots per riser card).

You can replace each standard riser with one of the following risers (or configure one of these riser cards instead of the standard 2 x8 riser using special bid or CTO) :

• Riser with one PCI Express x16 Gen 2 slot
• Riser with two PCI-X 64 bit/133 MHz slots
