Power Supplies
The Summit48si switch supports two hot-insert power supplies, shown in Figure 30, with one power
supply preinstalled at the factory. You can remove or install Summit48si power suppliesone at a
timewithout 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 sends:
A message to the syslog telling you which power supply failed
An SNMP trap to your network management software
