LEDs for hot-plug PCI slots:
Each hot-plug PCI
slot has three LEDs associated with it — two Attention
LEDs and one Power LED.
Ÿ
Power LED: This LED is on when the hot-plug PCI
slot is active and has power. An adapter must not
be added to or removed from the PCI slot when the
Power LED is on. When this LED is off, the PCI slot
is inactive and has no power applied. An adapter can
be installed when the Power LED for the PCI slot is
off. Refer to the operating system documentation to
determine if it supports hot-plug PCI adapters, and, if
so, how to disable the hot-plug PCI slot.
Ÿ
Attention LEDs: Each hot-plug PCI slot has an
Attention LED that is visible from the rear of the
server and one that can be seen from inside the
server. (The LEDs have the same meaning; they are
duplicated to be visible from outside or inside the
server.) An Attention LED flashes approximately
once per second when it is on. The meaning of the
Attention LEDs is defined by the operating system.
Refer to the operating system documentation to
determine if it supports hot-plug PCI adapters and, if
so, what the Attention LEDs indicate.
