Fan and temperature monitor
Each of the three cooling fans is monitored by the fan monitor circuit which forwards a warning to
the BPX switch system software if any fan falls below a preset RPM. Cabinet internal temperature
is also monitored by the ASM which sends the temperature to the system software to be displayed
on the NMS terminal. The range that can be displayed is 0 degrees to 60 degrees Centigrade.
