Cisco 7507
Power Supply Requirements
The Cisco 7505 comes equipped with one 600W AC-input power supply or one 600W DC-input
power supply. The AC-input power supply operates on AC-input power and supplies DC power to
the internal components. The DC-input power supply operates on DC-input power and supplies DC
power to the internal components.
The AC power receptacle (or DC-input terminal block), power on/off switch (or circuit breaker-type
switch on the DC-input power supply), and status LED are on the interface processor end of the
power supply. A modular power cable connects the AC-input power supply to the site AC power
source. A cable retention clip on the power supply AC receptacle prevents the cable from being
pulled out accidentally. The DC-input is supplied by a three-lead, 8-AWG cable that you provide.
Inside the AC-input or DC-input power supply, two small fans draw cooling air through the power
supply interior. The air flows in one side of the supply and out the other side, following the same
direction as the chassis cooling air.
