Add-In Boards

The PHP I/O carrier provides 10 PCI bus master slots.

CAUTION

Do not overload the PHP I/O carrier by installing add-in boards that draw excessive current. For expansion slot current limitations, see Appendix A, “Power System: Description/Calculating Power Usage” on page 191.

Add-in boards can be extremely sensitive to ESD and always require careful handling. After removing the board from the protective wrapper or from the carrier, place it component-side up on a nonconductive, static-free surface.

Do not slide the board over any surface.

NOTE

Running the SSU is optional for a PCI add-in board.

Installing/Replacing an Add-In Board

You can install an add-in board when the server is operating or not operating. The following procedure describes both scenarios.

The enhanced PCI hot-plug (EPHP) mechanism is a rotating part that actuates a switch located on the EPHP board. Each PCI slot has four indicator LEDs: two on the outside and two on the inside of the system. After the LED shows which slot is powered down, you can press the EPHP mechanism on the actuator, rotate the mechanism, and remove the PCI board. After a new

PCI board is installed, rotate the EPHP mechanism back into place to activate the switch and secure the board.

See Figure 30 (page 109) and Figure 31 (page 110).

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,” page 97).

CAUTION

Some accessory/option board outputs exceed Class 2 or limited power source limits and must use appropriate interconnecting cabling in accordance with the national electric code during installation.
