Connecting DC Power to the Cisco uBR10012 Router
This section describes how to connect the Cisco uBR10012 router to the two –48/–60 VDC power
sources that provide its operating power. The DC power sources can either be already present at the site,
or they can be provided by the external AC-input power shelves. If using the external 2400 W AC-input
power shelf, be certain you have already installed it, as described in the
Installation
For full power redundancy, each terminal block on the external power shelf must be connected to a
Note
separate power source. If using the optional 2400 W AC-input power shelf, full power redundancy also
requires that each of the AC power supplies in the shelf be connected to AC power sources that are on
separate circuit breakers.
Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement
