How to monitor SAN Switch's temperature

Dear all,

But when I add new device template(picture name's modifydevicetemplate.png) and add new bulk with
OID for monitor SAN Switch's temperature (picture name's editmonitor.png) then I test to monitor
I have a error like picture name's newmonitordevice.png. I try to test monitor by php script it's
