Environmental Monitoring
Environmental Monitoring
The Cisco ADE 2130 and 2140 Series appliance has protection circuits that monitor and detect
overcurrent, overvoltag e, and overtemper ature condition s inside the appliance. If the power supply shuts
down or latches off, a cycle of off for 15 seconds and on for 1 second will reset the power supply.

Overcurrent Protection (OCP)

The power supply shuts down and latches off after an overcurrent condition occurs. This latch is cleared
by a power interruption.
Note The power supply will not be damaged from power cycling.

Overvoltage Protection (OVP)

The power supply shuts down and latches off after an overvoltage condition occurs. This latch is cleared
by a power interruption.

Overtemperature Protection (OTP)

The power supply is protected against overtemperature conditions caused by the loss of fan cooling or
excessive ambient temperature. In an OTP condition, the power supply will shut down. When the power
supply temperature drops to the rated safety limit, the power supply restores power automatically.
