Power Connection Guidelines for DC-Powered Systems

Power Connection Guidelines for DC-Powered Systems

This section provides the basic guidelines for connecting the Catalyst 4500 series switch DC-input power supplies to the site power source or AC power shelf:

All power connection wiring should conform to local and national codes.

DC (–) and DC return (+) terminals are evaluated for use with 1/0 AWG wire (1400W DC supply only).

The ground terminal is evaluated for use with 6 AWG wire (10 AWG for the multi-input power supply).

DC (–) and DC return (+) wire lugs shall not exceed 0.83 inches in width (0.378 inches for the multi-input power supply).

For DC power cables, we recommend that you use commensurately rated, high-strand-count copper wire cable. Connection to the DC-input power supply requires one earth ground cable, one source DC (–), and one source DC return (+). The length of the cables depends on your switch location. These cables are not available from Cisco Systems. They are available from any commercial cable vendor.

The color coding of the source DC power cable leads depends on the color coding of the site DC power source. Typically, green or green and yellow indicate that the cable is a ground cable. Because there is no color code standard for source DC wiring, you must ensure that the power cables are connected to the DC-input power supply terminal block in the proper (+) and

(–)polarity. In some cases, the source DC cable leads might have a positive

(+) or a negative (–) label. This label is a relatively safe indication of the polarity, but you must verify the polarity by measuring the voltage between the DC cable leads. When making the measurement, the positive (+) lead and the negative (–) lead must always match the (+) and (–) labels on the DC-input power supply terminal block.
