F5 Power LED Yellow

F5 Power 1 LED turned yellow and Power 2 LED is green. Is the Power 1 module completely down which needed to be replaced or is there any other solution or reason?

Please provide output of tmsh show /sys hardware. We faced multiple power supply issues and we ended up replacing them. Power supply is a hot swappable.
