The Summit48i switch has built-in dual redundant power supplies. Each power supply has its own 
power socket. When the second power supply is connected to a second independent power source, both 
provide a redundant, load-shared power source to the Summit48i switch. If one of the power sources or 
power supplies fails, the second power supply provides all power needs, ensuring uninterrupted 
network operation. The switch also sends:

A message to the syslog to indicate which power supply failed

An SNMP trap to your network management station

The label on the rear of the Summit48i switch displays important information about the switch. Write 
down the following information before you install the switch:

Model number—Model number assigned to this device

Part number—Part number assigned to this device

Serial number—Manufacturing serial number for this device. Refer to the serial number when you 
contact Extreme Networks technical support

MAC address—Unique Ethernet MAC address assigned to this device

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.

Use the console port (9-pin, “D” type connector) for local management. This port allows you to attach a 
terminal and access the CLI via a serial connection.
