You can use the Boot ROM program saved in the Flash memory of the switch to upgrade the running
Boot ROM. With this command, a remote user can conveniently upgrade the BootRom by uploading the
Boot ROM to the switch through FTP and running this command. The Boot ROM can be used when the
switch restarts.

Enabling Auto Power Down on the 1000 Mbps Uplink Port
When auto power down is enabled on a 1000 Mbps uplink port, if the port is not connected to another
port, or if the peer port is shut down, the 1000 Mbps uplink port automatically enters the power save state,
so as to lower the power consumption of the switch.
Table 4-7 Follow these steps to enable auto power down on the 1000 Mbps uplink port:

Disabled by default.
Currently, the Ethernet switches only support configuring auto power down on 1000 Mbps uplink ports.
If you configure this feature on a 10/100Base-TX autosensing Ethernet port, the system shows an error
