Each switch comes with one 500 W alternating-current (AC) power supply. All
models have two power supply slots, enabling you to install a second power
supply for redundancy.
The power supplies are hot-swappable and can be swapped in or out of the device
while the device is running. You can remove and insert a power supply without
opening the chassis. A single power supply provides enough power for the entire
system.
The following sections provide further details about the power supplies for the
switches:
v Power status LEDs are listed in "Observing the power status LEDs" on page 22.
v Hardware specifications for the power supplies are listed in "Hardware
specifications," on page 61.
v "About redundant power supplies and power supply failure" on page 10.
