1 I/O function card slot 2 Power LEDs 3 Attention LEDs for PCI slots 4 Hot-plug 32-bit PCI slots 11-12 (bus C) 5 Hot-plug 32-bit PCI slots 6-10 (bus B) 6 Hot-plug 64-bit PCI slots 1-5 (bus A) LEDs for PCI Slots: Each PCI slot has three lights associated with it - two Attention lights and one Power On light. Power On Light: This light is on when the PCI slot is active and has power. Do not add or remove an adapter from the PCI slot when the Power On light is on. When this light is off, the PCI slot is inactive and has no power applied. You can install or remove an adapter when the Power On light is off. Refer to your operating system documentation to determine if it supports hot-plug PCI adapters. Attention Lights: Each PCI slot has two Attention lights: one that is visible from the rear of the server and one that is visible inside the server. (The lights have the same meaning; they are duplicated to be visible from outside or inside the server.) An Attention light flashes approximately once per second when it is on. The meaning of the Attention lights is defined by your operating system. Refer to your operating system documentation to determine if it supports hot-plug PCI adapters and, if so, what the Attention lights indicate. 174 Netfinity Server HMM
