v The PCI Express bus configuration is as follows: - Non-hot-plug, half-length PCI Express x8 (x8 lanes): slot 1 through slot 5 - Hot-plug, half-length PCI Express x8 (x8 lanes): slot 6 and slot 7 Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on. To install a non-hot-plug or hot-plug PCI Express adapter, complete the following steps. Note: For hot-pluggable adapters, make sure that the PCI Express hot-plug device driver is installed. 1. Read the safety information that begins on page v and "Installation guidelines" on page 26. 2. If the adapter is not hot-pluggable, turn off the server and peripheral devices, and disconnect the power cords and all external cables. 3. Remove the server cover (see "Removing the cover and bezel" on page 28) and determine which PCI Express expansion slot you will use for the adapter.

See the documentation that comes with the adapter for instructions for setting jumpers or switches and for cabling. Note: Route adapter cables before you install the adapter. 5. Rotate the adapter-retention bracket to the open position. 6. If you are installing the adapter in slot 6 or slot 7, push the orange adapter retention latch toward the rear of the server and open the tab. The power LED for the slot turns off. 7.
