Upgrading Boot Rom At Cli - H3C AR 46-20 Installation Manual

H3C AR 46 Series Routers Installation Manual
Step 2: Change the baud rate of the serial port on the RPU to a higher value. Refer
back to "Modify the serial interface parameters" in the subsection "Small Boot ROM
menu" in the section "Boot Menu".
Note:
The default baud rate of the serial port on the RPU is 9600 bps. Skip this step if you do
not want to modify it; but if you change it, note to reset it to 9600 bps after file transfer is
completed.
Step 3: Start the router and enter the main system. Press <Ctrl+B> when the system
prompts "Press Ctrl+B to enter Boot Menu... 3". Input the correct password to enter the
main Boot ROM menu.
Step 4: Select <3> in the main Boot ROM menu to enter the serial sub-menu.
Step 5: In the serial sub-menu, select <1> to download and run the application image
(note that this does not save the application image to Flash memory), or select <2> to
download it to Flash memory.
Step 6: Select the application image file and the XModem protocol in the Send File
window in the HyperTerminal. See Step 5 in the previous subsection.
Step 7: Send the file. See Step 6 in the previous subsection.
Step 8: If you select <1> in the serial port sub-menu, the application image runs
immediately after it is loaded; if you select <2>, the system returns to Main Menu and
boots from Flash memory after the write to Flash operation is done.
Note:
Upon completion of application image upgrade, the router reboots and checks Boot
ROM version for consistency before starting the Comware software. If the version of
the current extended Boot ROM image segment is not the same as that of the extended
segment to be started, the system automatically updates the Boot ROM image, and
displays "Update main BootROM. Updating...done. System will reboot..." Then, it
reboots again.
