The Summit48i switch supports up to two power supplies. Each power supply has its own power 
socket. When a second power supply is installed and 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 which ensures 
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 your switch. Write 
down the following information before you install the switch:

Model number—Shows the model number assigned to this device

Part number—Shows the part number assigned to this device

Serial number—Refer to the serial number when you contact Extreme Networks technical support

MAC address—Shows the 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) to attach a terminal and access the CLI via a serial 
connection. Use the console port for local management.
