CHAPTER 4 – OPERATING YOUR CABINET
4.2.3.2 NEW FAN PIN
FAN PIN restricts access to the fan controls. Once the FAN PIN has been set, one will have to correctly
key in the four-digit PIN before being allowed to switch the fan on or off. As such, the FAN PIN can be an
effective guard against unauthorized personnel operating the cabinet. FAN PIN can also effectively
prevent unauthorized shutdown of the cabinet when in fact it needs to be in operation continuously for a
prolonged period of time. Please note that continuous operation is recommended for enhanced safety.
It is recommended that the FAN PIN be issued only to personnel authorized to use the cabinet. By
default, this feature is disabled. Please follow the following steps to set a new FAN PIN so as to enable
this feature:
