Summit Switch Models
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
Reset Button
Use the reset button to cycle the switch down and bring the switch back up without powering off the
switch. Your saved switch configuration information is not lost; unsaved switch configurations are lost.
Use a non-conductive tool to push the reset button.
