Management Modes
The device supports the following modes:
•
Managed Mode
— Provides switch management through the web interface. From Managed mode,
you can move to Unmanaged mode by pressing the Mode button on the device, or you can move to
Secure mode using the web interface (see "Entering Secure Mode" on page63). Before leaving
Managed mode it is highly recommended to save the configuration (see "Uploading Files" on page82).
•
Unmanaged Mode
— In this mode, the device does not have an IP address; STP is disabled; there is no
web management interface, the CLI works in debug mode only; and there is no configuration in the
CDB—default configuration is used. From this mode, you can return to Managed mode by pressing
the Mode button on the device.
•
Secure Mode
— This mode keeps the existing configuration active, but it prevents users from making
configuration changes by removing the IP address of the device so that it becomes inaccessible for
configuration. In this mode, no web management interface is available, and CLI works in debug mode
only. From this mode, you can return to Managed mode by pressing the Mode button on the device.
All modes are maintained through power cycles. The Managed Mode LED provides an indication of the
current mode (see "On the PowerConnect 28xx front panel there is a Managed Mode LED monitoring
the switch node as well as indicating diagnostic test results. The following table describes the Managed
Mode LED indications. For more information about management modes and transitioning between
them, see "Management Modes" on page 50." on page 22).
