Power Supplies
The Cisco SCE8000 platform supports redundant AC- or DC-input power supplies. The following power
supplies are available for the Cisco SCE8000 platform:
• 2700 W DC input (PWR-2700-DC/4): uses an external terminal block on the back side of the chassis
for input power connection.
• 2700 W AC input (PWR-2700-AC/4): uses an external power cord directly connected to the AC
power supply.

Figure 2-11 PWR-2700-DC/4
The AC-input and DC-input power supplies support redundancy. When power is removed from one
supply, the redundant power feature causes the second supply to produce f ull power.
