4.4.1 Sun Fire X4150 Server PCIe Card Guidelines
The PCI expansion system is configured using a variety of riser cards. The connector
is an x16 mechanically but electrically an x8. Only low profile half length cards are
supported.
▼ To Remove PCIe Cards
Caution – Ensure that all power is removed from the server before removing or
installing expansion cards. You must disconnect the power cables before performing
this procedure.
1. Locate the PCIe card that you want to remove, and note its corresponding riser
board.
See Section 1.4, “Sun Fire X4150 Server Rear Panel Features” on page 1-7 for more
information about PCIe slots and their locations.
2. If necessary, make a note of where the PCIe cards are installed.
3. Unplug all data cables from the card.
Note the location of all cables for reinstallation later.
4. Remove the riser board (
FIGURE 4-11).
See Section 4.3, “Servicing PCIe Risers” on page 4-14.
5. Carefully remove the PCIe card from the riser board connector.
6. Place the PCIe card on an antistatic mat.
7. If you are not replacing the PCIe card, install a PCIe filler panel.
PCIe filler panels are located in the motherboard back panel.
