Warning
Only a DC power source that is isolated from the AC main power source 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 6260 system. This requirement ensures that
in a catastrophic power source fault condition, hazardous voltages are not present on power
terminals and connectors.
