Upgrading Application Program Through Serial Port; Upgrading Application Program Through Ethernet Interface; Configuring Ethernet Parameters - H3C MSR 30-20 ROUTER Installation Manual

The file name, size and path vary in different situations. Check the current version of BootROM and
application program in order to use correct file.
This method only upgrades a part of BootROM. You can re-upgrade when error occurs.
Restore the baud rate in the HyperTerminal to 9600 bps (the default) after upgrading the BootROM,
so as to ensure normal display on the console screen after system boot or reboot.

Upgrading Application Program Through Serial Port

Upgrading of application program through serial port is implemented under serial submenu. Enter <2>
in the main BootROM menu to enter the serial submenu. Refer to section "Enter serial submenu" for
detailed descriptions.
For example, when you upgrade application program:
First, change serial baud rate to speed up upgrading (refer to section "Modifying Serial Port
Parameters" for details), and then enter <2> under serial submenu. The system prompts:
Select program file please.
Waiting...CC
Select application program file and send it. Upgrading application program with serial port takes the
similar steps with upgrading BootROM. Refer to section "Upgrading BootROM" for details.
Generally an application program is more than 10M in size. Even if the baud rate is changed to 115200
bps, the upgrading takes about 30 minutes. Therefore, it is recommended you upgrade through
Ethernet interface.

Upgrading Application Program Through Ethernet Interface

Enter <3> under the main BootROM menu to enter the Ethernet interface submenu. Refer to section
"Enter Ethernet Interface submenu" for details.

Configuring Ethernet Parameters

Before upgrading application program through Ethernet interface, we need to configure the Ethernet
interface of the router, as follows:
Enter <3> under the main BootROM menu to enter the Ethernet Interface submenu. Then, enter <5> to
enter the Configure Ethernet interface menu:
Note: Two protocols for download, tftp & ftp.
You can modify the flags following the menu except the boot device.
tftp--0x80, ftp--0x0.
'.' = clear field; '-' = go to previous field;
