SRPL8 Server System Product Guide 111

Removing an Add-In Board

You can remove an add-in board when the server is operating or not operating. The following
procedure describes both scenarios.
CAUTION
Expansion slot covers must be installed on all vacant slots to maintain the
electromagnetic emission characteristics of the server and to ensure proper
cooling of the server components.
1. Observe the safety precautions, warnings, and cautions at the beginning of this chapter.
2. Remove the PCI bus hot-plug cover (see “Removing the PCI Bus Hot-Plug Cover” on
page 97).
3. Disconnect any cables attached to the board you are removing.
4. Remove and save the screw securing the add-in board to the expansion slot frame.
5. If your server is NOT operating, skip this step. If your server IS operating:
• Access the PHP GUI on the CD-ROM that came with your server.
• Use the PHP GUI to power down the appropriate PCI slot.
6. Grasp the board by the top edge or upper corners, and carefully pull it upward until the edge
connector of the board pulls free from the connector on the PHP I/O carrier. Make sure that
you do not scrape the board against other components.
7. Store the board in an antistatic protective wrapper.
8. Install an expansion slot cover (see Figure 30 on page 109) over the vacant slot. The tapered
foot of the cover must fit into the mating slot in the bottom of the expansion slot frame.
9. Install the power enabling switch actuator over the vacant slot. The spring at the end of the
actuator rests on the power enabling switch.
10. Secure the cover and actuator to the frame using the retaining screw.
11. Reinstall the top cover (see “Installing the Top Cover” on page 99).
I/O Riser Board

Removing the I/O Riser Board

See Figure 32.
1. Observe the safety precautions, warnings, and cautions at the beginning of this chapter.
2. Verify that system power is OFF and that the AC power cord is removed from the back of the
system, and that all cables (mouse, keyboard, etc.) are disconnected from the I/O back panel.
3. Remove the top cover and 240 VA protective covers (see “Removing the Top Cover” on
page 98).
4. Disconnect the ICMB signal cable from the I/O riser board (A in Figure 32).
5. Remove and save the screw (B in Figure 32).
6. Holding the board by the top edge or upper corners, pull it straight upward, away from the
PHP I/O carrier until the edge connector of the board pulls free from its connector. Make sure
that you do not scrape the board against other components.
7. Place the board on a nonconductive, static-free surface, or store it in an antistatic protective
wrapper.
