[j-nsp] Fan Tray Failure in JM20

[Jonas Frey (Probe Networks)]

My guess is that this is some error on the i2c bus with the fans.
Try rebooting the whole unit to see if the error persists.

Its very unlikely that all 4 fans of a fantray fail totally.

If you have a spare unit try the fantrays in that one to see if it is
really related to the chassis.
