CPU-I/O Enclosure Status LEDs
On ftServer 2600, 4500, and 6300 systems, behind the bezel, the front of each
CPU-I/O enclosure contains the set of system LEDs shown in Figure 3-2. The LEDs
indicate faults detected in a range of enclosure components to help you identify
problems and expedite the repair process.
When the system detects a component in a fault state, the component’s corresponding
LED lights up. If, for example, a component reaches its voltage threshold, the VLT LED
illuminates. If the component returns to normal, its LED goes out.
In some cases, the component is automatically taken offline, and its LED stays lit until
the component is replaced or brought back online.
