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.
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.
Installing 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.
1.
Observe the safety precautions, warnings, and cautions at the beginning of
this chapter.
2.
Remove the PCI bus hot-plug cover following procedures previously
described in this chapter.
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.
