Installing Additional PCIe/PCI-X Cards
The rx2660 server supports PCI-X cards and PCI-Express (PCIe) cards. There are three PCIe/PCI-X
slots in the I/O backplane located on the system board. Depending on your server configuration,
you have one of the following I/O backplane assemblies, with the included riser board:
PCI-X riser board:
Three full-length PCI-X public slots
PCIe/PCI-X riser board:
Two PCIe x8 public slots and one full-length PCI-X public slot
NOTE: Wake-on-LAN is not enabled on any of the PCIe/PCI-X slots.
PCIe/PCI-X hot-plugging is not supported on the rx2660 server.
Removing the I/O Backplane from the Server
To install an additional PCIe/PCI-X card into the server, you must first remove the I/O backplane
from the system board.
To remove the I/O backplane assembly, follow these steps:
1. Remove the top cover. See “Removing the Top Cover” (page 48).
