Cisco Systems 2140 Manual De Usuario

Proceed to the next section, “

installation.

The Cisco ADE 2130 and 2140 Series appliance has the capability of using either an AC power supply 
or a DC power supply. 

To ensure proper cooling if only one power supply is installed, the power supply must be in the 
right-hand slot and the power supply blank filler panel must be in the left-hand slot. (See 

.)

If the DC power supply is used, ensure that the appliance is properly grounded.

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the 
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection 
authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that 
the protective device is rated not greater than: 10 Amps Statement 1005

Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. 
Statement 1

Do not touch the power supply when the power cord is connected. For systems with a power switch, 
line voltages are present within the power supply even when the power switch is off and the power 
cord is connected. For systems without a power switch, line voltages are present within the power 
supply when the power cord is connected. Statement 4

Never install an AC power module and a DC power module in the same chassis. Statement 1050

This unit might have more than one power supply connection. All connections must be removed to
