Site Requirement Guidelines

DC-Powered Systems

In sites where the Cisco 12012 operates with DC-input power supplies, observe the
following guidelines:
•
Each DC-input power supply requires a dedicated 60-amp service. Table 2-4 lists the
nominal and acceptable value ranges for source DC power.
•
For DC power cables, we recommend that you use 4-AWG, high strand count wire cable
(three leads).
•
Lugs should be dual hole and able to fit over M6 terminal studs at .625-inch (15.86-mm)
centers. Figure 2-3 shows the type of lug required for the DC-input cable connections.
