Downloading Using Xmodem Protocol (Xmodem/Crc-xmodem)
Use the Xmodem or CRC-xmodem options to load the new firmware version through the Console Port.
Depending on the communications software programs available, choose:
n
Xmodem: Terminates packets with a “checksum”
n
CRC-xmodem: Terminates packets with a Cyclic Redundancy
Check (CRC).
è To load firmware using Xmodem or CRC-xmodem:
1. Connect a terminal to the Console Port using a communications
software program (Procomm TM or Windows TM Terminal).
2. Select either the Xmodem option or CRC-xmodem option, depending
on your communications software.
The following message appears:
Ready for XMODEM download. Use several ^XÕs to cancel
3. Set the communication program to initiate the file transfer to the
unit.
4. The unit begins the file download. A message similar to the following appears:
XMODEM: received 160450 bytes in 00:03:36; 800 bytes/s
transfer rate
After the loaded code for the new firmware is validated, the flash memory is programmed and the unit will restart with the new code.
The firmware consists of the boot block and the application code. During the firmware download, the application code is replaced, but the boot
block is not.
