directions simultaneously. This bandwidth is not affected by what is happening on other PCI Express
buses or legacy PCI/PCI-X buses (provided that total bandwidth can be handled by the CPU and the
memory subsystem.) The transmission protocol is somewhat similar to that used for a LAN connection
and contains error correction and detection, packet addressing, and other network features.
PCI Express improves system attributes. PCI Express enables a low-power, scalable, high-bandwidth
communication path with a small number of connections (wires) compared to traditional parallel
interfaces (for example, PCI).
The PCI Express I/O slots can support other PCI Express cards with lesser bus bandwidth than what is
physically defined for the slot. Use the following table to determine compatibility.
For example, a PCI Express x8 card does not work in a PCI Express x1 slot, but a PCI Express x1 card
works in a PCI Express x8 slot.

Removing PCI or PCI Express cards
1.
Disconnect power from the system (
Pre-disassembly procedures on page 55
), and remove the
access panel (
Access panel on page 61
). Place the workstation on its side with the system board
facing up. Remove the PCI retainer (
PCI retainer on page 73
) if present.
2.
Open the PCI retention clamp by pressing down on the two green clips at the ends of the clamp
(1)
and rotating the clamp toward the back of the system.
