Power Requirements

The central office (CO) power source or rectifier supplies external power to the system as -48 VDC from the fuse and alarm panel. Power connections from the fuse and alarm panel are wired separately to the Cisco 6130 chassis and the fan tray. Connections for single- and dual- power feeds are provided. The power input connections are redundant, and only one is absolutely necessary for system operation. The nominal voltage is -48 VDC; the minimum operating value is -36 VDC; and the maximum operating value is -60 VDC.

Before you connect the system to a power source, verify that the power source is properly grounded and that it falls within the internal power supply rating. For the internal power supply rating for the Cisco 6130 chassis, refer to the power supply label on the back of the chassis.

Depending on your configuration type, calculate the typical power required for each Cisco 6100 Series component. After you calculate the typical power, determine the minimum fuse value for each component that is wired to the fuse and alarm panel. Use Table 3 to calculate the minimum fuse rating necessary for each of your Cisco 6100 Series system components.

Note The power rating label supplied on the rear of each chassis and fan tray indicates the maximum fuse value for the chassis or the fan tray.
