Connecting the Power Cord

Warning Only a DC power source that is isolated from AC mains with reinforced insulation, and that complies with the other safety extra-low voltage (SELV) requirements in UL1950, CSA 950 3rd Edition, EN 60950, and IEC950, can be connected to a Cisco 11506 system. This requirement ensures that in a catastrophic power source fault condition, hazardous voltages are not present on power terminals and connectors.

Warning This unit might have more than one power supply connection; all connections must be removed completely for you to completely remove power from the unit.

To connect each CSS 11506 DC power supply to a power source:

1.On the power supply, ensure that the CSS power switch is in the O (off) position.

2.Locate the power supply DC terminal block, as shown in Figure 2-15.
