Power Considerations

You configure your Cisco ADE 2130 and 2140 Series appliance with either an AC-input or DC-input power supply. (For power supply pinout descriptions, see the “AC and DC Power Supplies” section on page 1-15.) Both power supplies are hot-swappable. You can configure your appliance for redundancy with either:

•Two AC-input power supplies

•Two DC-input power supplies

Or, you can choose either one AC-input or one DC-input power supply for nonredundancy.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

When the appliance is configured with two power supply modules, the hot-swap feature allows you to replace a failed power supply without interrupting the appliance operation. During this hot-swap replacement, a maximum of two minutes is recommended.

Caution If only one power supply is installed, it must be in the right-hand slot and a power supply blank filler panel must be installed in the left-hand slot to ensure proper cooling. (See location 5 in Figure 1-5 on page 1-9.)

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

AC Power Supply Safety Considerations

Ensure all power connections conform to the rules and regulations in the National Electrical Codes (NECs), as well as local codes. Follow these precautions and recommendations when planning power connections to your appliance:

•Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power (free of spikes and noise). Install a power conditioner if necessary.

•The AC power supply includes the following features:
