Warning

Use copper conductors only. Statement 1025

A Cisco 3800 series router with a DC-input power supply requires copper wire for the power connections. Table 1 and Table 2

summarize the DC wiring requirements.

If you connect dual DC power sources to a Cisco 3825 router, both sources must be the same polarity and voltage.

For a Cisco 3845 router, the safety ground wire connection must be at the same potential as the 0 V (return) connection.
