Power Sockets
The Summit48i switch supports two power supplies. Each power supply has its own
power socket. The power supplies provide a redundant, load-shared power source to
the Summit48i switch.
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:
• Send a message to the syslog telling you which power supply failed
• Send an SNMP trap to your network management software
Note: Summit48i switch power supplies must only be serviced by personnel
trained by Extreme Networks.
