Dual DC Power Supply Configuration in Cisco 3825 Routers
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 have the
same polarity (with respect to ground) and voltage (within 0.25 V). Do not connect –DC-grounded and
+DC-grounded dual sources to a Cisco 3825 router.
