A Catalyst 4500 series switch can use a 1000 W, 1300 W, 1400 W, 2800 W (see
Figure 1-17), or 4200 W (with two inputs, see Figure 1-18) AC-input power
supply , a 1400 W DC-input power supply with integrated PEM (see Figure 1-19),
or a 1400 W DC multiple-input power supply (see Figure 1-20). The power
supplies are hot-swappable. If you have power supplies of different types installed
in the two bays, only one will be active and some power features will not be
available. The power supply in the left bay is PS1, the one in the right bay is PS2.
The AC-input power supply has a power cord that connects each power supply to
the site power source. The DC-input power supply is equipped with a input
terminal block that is directly connected to the site power wiring.
Each power supply has an ON/OFF switch that supplies power to the switch. For
information on removing and replacing power supplies, see the "Removing and
Replacing the Power Supply" section on page 4-2.
