Magma PCI Expansion System User Manual

The Magma 6 Slot PCI Express® to PCI-X Expansion System (Model 
PE6R4) is a general-purpose PCI bus expansion chassis. The 
expansion chassis is fully compliant with the PCI Local Bus 
Specification. Because PCI-X is backward compatible with PCI, both 
card types can be used with PE6R4. Therefore, to keep things simple, 
the terms PCI and PCI-X will be used interchangeably throughout this 
manual. 

PE6R4 consists of a PCI Express host card, a pair of 1–meter 
Infiniband™ cables, a rack-mount enclosure containing a 6 slot PCI-X 
backplane, a power supply, and cooling fans.
