M7i FIC LEDs

 

Two large alarm LEDs are located on the right of the FIC (see FIC with Fast Ethernet Ports and FIC with Gigabit Ethernet Port). The circular red LED lights to indicate a critical condition that can result in a system shutdown. The triangular yellow LED lights to indicate a less severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously.

To deactivate red and yellow alarms, you must clear the condition that caused the alarm.

Table 1 describes the alarm LEDs in more detail.
