Cisco Systems Cisco 12008 manual Dimensions of the Lugs Used with the Source DC Power Cables

Site Requirements Guidelines

Each set of power terminals on the DC-input power supply faceplate consists of two 6-mm, metric-threaded, nickel-plated brass studs centered 0.625 inch apart. The earth ground studs extend 0.52 inch (13.2 mm) above the power supply faceplate; the set of positive (+) and negative (–) studs extend 0.9 inch (22.9 mm) above the faceplate. The nickel plating on the studs enhance their conductivity and ensure corrosion resistance.

For convenience, the lockwashers and nuts for connecting the source DC cables to the nickel-plated brass studs are loosely mounted on the studs ready for use.

In making source DC connections to the power supply, use the power cables and lugs having the specifications outlined in Table 2-2. An equivalent 2-hole lug is acceptable as a substitute for the Panduit DC power cable lug.
