Hardware Features

AC and DC Power Supplies

The Cisco ADE 2130 and 2140 Series appliance is equipped with either a 110-V or 220-V AC power supply or a –48-V to –60-V DC power supply (see locations 4 and 5 in Figure 1-5 on page 1-9).

Note Figure 1-5 on page 1-9shows an AC and DC power supply together for illustration purposes. Never install an AC or DC power supply in the same appliance.

Both power supplies are capable of operating in redundant mode. A power supply blank filler panel is used for the empty power supply slot and is supplied with an appliance without redundancy.

The power supply is rated for 600-W output capacity in full AC or DC input voltage.

Each power supply incorporates a single 40-mm fan for cooling, which also contributes to overall appliance cooling. The cooling air enters the power supply from the power distribution side. If airflow through the power supply is insufficient, the overtemperature protection circuits activate a shutdown before the temperature passes the maximum rated temperature.

Caution 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 Figure 4-10 on page 4-20.)

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

To maintain hot-swap capability, ensure that an active power supply is in both power supply slots before replacing (hot-swapping) a power supply. Check the power supply LED to determine which power supply module has failed. (See location 2 in Figure 4-9 on page 4-18for either AC or DC power supply.)

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

AC Power Supply Input

A single receptacle is provided at the rear of the AC power supply for AC input.

DC Power Supply Input

The Cisco ADE 2130 and 2140 Series appliance uses a small, two-wire DC power Molex terminal block connector for input to the power supply.

With the connector installed in the appliance, the pins from top to bottom of the DC power terminal block are labeled – and +, respectively.

Table 1-14lists the pinout configuration for the connector.
