Approved Scenarios and Scenarios Not Approved for Dual DC Power Supply Configuration in Cisco
2800 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 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 Cisco 2811, Cisco 2821, and Cisco 2851 routers.
Caution
Dual sources with opposite-polarity grounding damage equipment.
