Adapter LED states
The LEDs on the adapter provide information about the operation status of the adapter. The LEDs are
visible through the mounting bracket. Figure 2 on page 14 shows the location of the LEDs. Table 9
describes the different LED states and what those states indicate.
Table 9. Adapter LEDs and descriptions
LED Light Description
Speed Yellow 10 Mbps or 100 Mbps
Green 1000 Mbps or 1 Gbps
Activity/link Green flashing Active link or data activity
