5.1.1 Boot ROM Command Mode
During the POST process, you can enter a “Boot ROM Command” mode
by pressing <ENTER> key as shown in Figure 68.
Figure 68 shows dual images in the switch. One firmware is in Slot 0 and
the other firmware is in Slot 1. The later version will be selected to boot the
system automatically.
Enter the “?” key to show the help messages for all available commands.
Although the commands are helpful in some situation, we
STRONGLY suggest users not to use them if you don’t
know the command function.
