Power Specifications

This section describes the power specifications for the Cisco Nexus 2000 Series FEXs.

The power supplies connect directly to the system through connectors attached to the baseboard through cables. One connector is on the baseboard for each power supply. AC input is through an IEC connector mounted on the power supply front panel. Table B-1 lists the specifications for the Cisco Nexus 2000 Series FEX power supplies.
