If one power supply 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 both when a power supply fails and when a
power supply is hot swapped
