A BIG-IP Administrator needs to verify the state of equipment in the data center.

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.
