The following table describes the SFP LED indications.
Managed Mode Button
The PowerConnect 2708/2716/2724/2748 has a Managed Mode push button on the front panel.
The Managed Mode button is for changing between Managed Mode and Unmanaged (or
Secure) Mode. After a change from Unmanaged (or Secure) Mode to Managed Mode, the
switch restores the configuration values to factory default settings.

• Factory default configuration (192.168.2.1) is set as the switch IP address.
• Subnet mask changes to 255.255.255.0
