Cisco7206 Router Shelf

The Cisco7206 router shelf can be ordered with either 280W AC-input or 280W DC-input power
supplies.
•The AC-input power supply uses a po wer fact or corre ctor t hat a llo ws th e Cis co7206 router shelf
to operate on input voltage and frequency within the ranges of 100 to 240VAC and 50/60Hz.
•Each AC-input power supply operating at 120 VAC requires a minimum of 5A service. We
recommend powering the Cisco7206 router shelf from a 15A receptacle at the power source.

Cisco7200 Series 280-Watt AC-Input Power Supply Replacement Instructions (Part Number
78-3227-xx) that shipped with your Cisco7206 router shelf.
•The DC-input power supply operates at –48 VDC input voltage and supplies +5V, +12V, –12V,
and +3V DC power to the router shelf internal components through the router midplane.
•Each DC-input power supply operating at –48 VDC in North America requires a minimum of
14A service. Each DC-input power supply operating at –60 VDC in the European Community
requires a minimum of 8A service. We recommend powering the Cisco7206 router shelf from a
15A receptacle at the power source.

Note We recommend attaching dual power supplies to independent power sources for full
redundancy. We also recommen d an uninterruptable power source to protect against power failures
at your site. Each AC-input po wer s upply o perati ng at 20 0 VAC requires a mini mum of 20A s ervic e.
We recommend powering the Cisco AS5800 from a 20A, 200 to 240 VAC receptacle at the power
source.
