Connecting the Router to a DC Power Source
This section provides the procedure for connecting your router to a DC power
source (
).
Note
We recommend each DC PDU be connected to an independent power source for
full redundancy. We also recommend that you use an uninterruptable power
source (UPS) to protect against power failures at your site.
