Chapter 1 Product Overview
Switch Components
Power Supplies
The
Catalyst 4000 series switches
can use a 400 W AC-input power supply (see
Figure 1-5
), a 400 W DC-input power supply (see
Figure 1-6
), or a 650 W
DC-input power supply (see
Figure 1-7
). The AC-input power supply has a power
cord that connects each power supply to the site power source. The DC-input
power supplies are equipped with a compression-style input terminal block that is
directly connected to the site power wiring.
The power supply does not have a power switch. Power is provided when the
power cord and wiring are installed and plugged into an electrical outlet and the
unit is fully seated in the system chassis.
