Description
This article describes how to detect FortiSwitch-PoE fault

Scope
For FortiSwitch-424D-POE v6.2.0 build0200

Solution
1) Verify if the FortiSwitch Model and switchport supports PoE, because certain FortiSwitch models have no PoE support at all, and certain models have Half PoE and Full PoE support. 
Check FortiSwitch Model datasheet for PoE support related info

2) Is this a new unit or prior to this issue, has FortiSwitch PoE worked fine?

3) Prior to this issue, was there any change made on the Switch or was there any power-outage affecting this Switch

4) Reset PoE on the FortiSwitch using the below command and test PoE:
# execute switch-controller poe-reset

5) Try below test on the FortiSwitch during maintenance window and check PoE status:

Unplug all cables and gracefully shutdown the Switch and wait for 15-30 mins to let it cool off, then power on the device with only console cable and PSU cord
# execute shutdown 

6) Try factory-resetting the Switch once: 
# execute factoryreset

Note: Download config backup before attempting FortiSwitch factory-reset

7) Check if the FortiSwitch port shows Power-Status code Fault:

# get switch poe inline
# diagnose switch poe status port11

Port(11) Power:0.00W, Power-Status code: 5(Fault)              
Power-Up Mode: Normal Mode
Power Fault: Error Type 6 (Startup Failure)
Remote Power Device Type: IEEE802.3AF PD
Power Class: 0
Defined Max Power: 16.2W, Priority: Low.
Voltage: 0.00V
Current: 0mA
Temperature: 53.75 Centigrade

8) Check if FortiSwitch is showing invalid PoE firmware version 0.0.0.0 as shown below:

# get hardware status
Poe Firmware Version: 0.0.0.0

9) In FortiSwitch '# execute log display' may show PoE warnings as shown below:

1969-12-31 16:02:07 log_id=0101002010 type=event subtype=poe pri=warning vd=root action="poe-debug" user="poed" status="None" msg=" doFailDetail:/bin/poed: time out
1969-12-31 16:02:07 log_id=0101002010 type=event subtype=poe pri=warning vd=root action="poe-debug" user="poed" status="None" msg=" doFailDetail:/bin/poed: time out

10) If willing, upgrade affected FortiSwitch to latest firmware in v6.2.x or 6.4.x stream and check if the issue exists

11) If the issue persists, log a ticket with Fortinet Support and attach the following logs from the affected FortiSwitch:

      # get switch poe inline
# diagnose switch poe status
# get hardware status

# diagnose sys fan status         
# diag sys pcb temp               
# diagnose sys psu status         

# show full
# diag debug report
