Hot-Plug PCI Indicator Board Interface (J3D1)
The hot-plug PCI indicator board (HPIB) contains the necessary LEDs and push button
switches to help the user run PCI hot-plug (PHP) operations.
To indicate slot status, each PHP slot contains a green LED and amber LED. The actual
interpretation of the LEDs depends on the operating system running on the system.
Each PHP slot also has a momentary switch. When you press this switch, the baseboard
notifies the operating system that a PHP operation on the respective slot is requested. If
a PHP operation is supported by the operating system, the user momentarily presses the
switch and then waits for the operating system to signal via the LEDs that the PHP slot
has been disabled. The user can then perform the desired PHP operation on the slot, such
asreplacing,removing,oraddingaPCIadapter.Whentheuserwantstheoperating
