Power Supplies
The Summit48si switch supports two hot-insert power supplies, shown in Figure 4-15,
with one power supply preinstalled at the factory. You can remove or install
Summit48si power supplies—one at a time—without interrupting operation, and each
power supply has its own power socket, which allows you to connect independent
power sources for each power supply. One functioning power supply must always be
installed. Two power supplies operate in a load-sharing manner and increase the
reliability of the switch.

Note: See Chapter 5 for information about removing and installing power
supplies.
If one of the power supplies fails, or if source power to one of the power supplies fails,
the second power supply takes over, ensuring uninterrupted network operation. The
switch also does the following:
