Approved Scenarios and Scenarios Not Approved for Dual DC Power Supply Configuration

You can connect a single DC power source to either the A input or the B input. If there are dual power sources, connect one

source to the A input and one source to the B input. Both sources must be the same polarity (with respect to ground) and voltage

(within 0.25 volts). Do not connect –DC grounded and +DC grounded dual sources to a Cisco 3825 series integrated router.

Dual sources with opposite-polarity grounding damage equipment.

Caution

In Figure 16, either the positive source terminal or the negative source terminal is tied to ground.
