Introduction - Flex System PCIe Expansion Node

The Flex System PCIe Expansion Node can provide PCI express expansion to a host compute node in an Flex System.

The PCIe Expansion Node supports up to two additional I/O expansion adapters for a host compute node and up to four additional PCIe adapters.

The PCIe Expansion Node provides the following:

Two slots for two I/O expansion adapters
Two slots for up to two full-height full-length or full-height half-length PCIe adapters
Two expansion connections for up to two low-profile PCIe adapters

Note: A single 4-connector auxiliary power cable is provided with full-length PCIe adapters that require more power than can be supplied with the two 2-connector auxiliary power cables that you might have received with your PCIe Expansion Node. Be sure to use the cable that comes with your adapter. For a list of supported adapters, see the IBM ServerProven website ServerProven: http://www-03.ibm.com/systems/info/x86servers/serverproven/compat/us/.

The PCIe Expansion Node has two slots for full-length PCIe adapters and two slots for low-profile PCIe adapters.

Note: Low profile adapters can be used in the full-length slots if extension brackets are used to secure the adapter in the slot.

The PCIe Expansion Node comes with a limited warranty. For information about the terms of the warranty, see the Warranty Information document for your PCIe Expansion Node. This document is available on the IBM Documentation CD.

The Flex System PCIe Expansion Node is supported in the Flex System Enterprise Chassis only. You can obtain up-to-date information about the PCIe Expansion Node at the IBM Systems website.

The PCIe Expansion Node might have features that are not described in the documentation that comes with the product. The documentation might be updated occasionally to include information about those features. Technical updates might also be available to provide additional information that is not included in the PCIe Expansion Node documentation.
