Response format - Verbose Mode

Note: DEVICE get activeFaultList  only retrieves Fault List of the queried Device. For complete fault list, every Server class device will need to be queried separately.

+OK "value":[{"id":INDICATOR_NONE_IN_DEVICE "name":"No fault in device" "faults":[] "serialNumber":"01842216"} {"id":INDICATOR_NONE_IN_DEVICE "name":"No fault in device" "faults":[] "serialNumber":"01882935"}]

+OK “Value”:


"name":"No fault in device"

"faults":[ ]


Header   Fault Type (Major, Minor, None) Fault Type Description    Fault List   Device Serial Number 

Fault Type, Description, Fault List and Device Serial number repeat in the response for the following:
1. Every Device using connected Server device as Proxy. For eg. Expanders
2. Major faults
3. Minor faults
Repeat format: Header :[{ Fault type  Fault Type Description  Fault List  Device Serial No } { Fault Type  Fault Type Description  Fault List  Device Serial No. } {…....}]

Response Header
+OK “Value”

Fault Type

Fault Type Description
"name": "No fault in device" or "Minor Fault in System" or "Major Fault in System"

Fault List

Header    Fault ID    Fault Description  


Fault ID: One of the fault IDs from the Fault List

Fault List may carry multiple Fault ID and Fault Descriptions separated by { }

Response Format - Non Verbose Mode

Non Verbose responses do no include the Fault ID and instead list the Fault ID Number (listed in the last column of fault list). 

Non verbose responses do not include explicity state Fault Type and instead refer to a Fault Indicator number as listed below:

Indicator Description ID
INDICATOR_NONE_IN_DEVICE No fault in device 5

+OK [[2 "Minor Fault in Device" [ [89 "Cooling fan malfunction.  Check filter and fan."]] "02196874"]]


[ [ 2

"Minor Fault in Device"

[ [ 89

" Cooling fan malfunction. Check filter and fan. " ]]

"02196874" ]]
