Actual exam question for F5's F5CAB1 exam
Question #: 3
Topic #: 2
A BIG-IP Administrator needs to verify the state of equipment in the data center.
A BIG-IP appliance has asolid yellow indicatoron the status LED.
How should the administrator interpret this LED indicator?

Suggested Answer: C Vote an answer

BIG-IP hardware platforms use chassis LEDs to indicate system health states.
Asolid yellow status LEDtypically indicates awarning condition, such as:
* A non-critical hardware alert
* A temperature threshold nearing limit
* A minor fan or sensor irregularity
* Other non-fatal environmental or system conditions
This state reflects awarning-level alarm, meaning the unit is operational but requires investigation.
Why the other options are incorrect
A). Halted or EUD mode
* This is associated with different LED patterns (usually flashing conditions or specific color codes), not a solid yellow status LED.
B). Standby in device group
* HA state is not indicated by the chassis status LED.
* Standby status is alogicaldevice state, not a hardware LED state.
D). Power supply failure
* Power supply indicators use separate LEDs located on each power module (usually flashing amber/red), not the system status LED.
Thus, asolid yellow status indicatorsignifies awarning-level alarm.
