Power Specifications

Power specifications include power requirements for the switch modules, maximum power available for the switch, power supply specifications, and power cable specifications.

Power Requirements for Switch Modules

To determine the number of power supplies required to operate all the modules in a switch, add together the maximum power amounts for each module in the switch, divide the sum by 3000 W, and if there is a fractional amount in the result, add 1 to the result. For n+1 redundancy, add one more power supply. For n+n redundancy, double the number of power supplies and provision for a second power source.

To determine the typical consumption, add together the typical power amounts for each module in the switch.

If you order new power supplies, make sure that the new power supplies use the same type of power (AC or DC) as the rest of the power supplies in the same switch. Do not use a mix of AC and DC power sources for a switch.

3-kW DC Power Supply Power Cord Specifications

Each 3-kW DC power supply requires four customer-supplied power cables (two negative cables and two positive cables). We recommend using 6 gauge cables. Cisco supplies 6-gauge lugs for connections to the power supply. The customer must supply the connectors required to connect the cables to the DC power source.

Transceivers, Connectors, and Cables
