Power Requirements
The Cisco AS5850 ships configured for either AC-input or DC-input power with loadsharing, depending
on your order.
AC-Input Power Specifications
The Cisco AS5850 accepts AC-input power using a separate, self-contained AC-input power shelf,
which converts AC-input power into DC output for use by the universal gateway. The AC-input power
shelf is rack-mounted and has a safety cover that shields the electrical connections in the power shelf
rear.
The AC-input to DC-output connection supplies –48 VDC-output power to the PEMFs. Power flows
through the filter module to the backplane, where it is distributed to the RSC and feature cards.
