Interpreting the PCI Card Status Lights

Each PCI card has three status lights that are arranged in a traffic light configuration directly above the card on the PCI card cage. These status lights indicate the current condition of the card. Figure 3-1 shows the status lights, and Table 3-1 explains their meaning. A status light sticker is attached below the PCI card doors, in the rear of the cabinet, for easy reference.
