Chapter 4 Installing the Cisco SCE8000 GBE Chassis
Preparing for Installation
Table 4-5 lists the Cisco SCE 8000 GBE DC power supply specification.
Note The DC supplies each have the provision for a dual connection to the power source in order to permit
high-power operation without exceeding current ratings. For the SCE 8000, it is not necessary to connect
both of these inputs to DC power sources; it is sufficient to connect only the '1' connections.
