4.2.8 File Transfer Protocol (FTP)
The CMR-8500 also supports changes to the resident software and firmware by means of the File
Transfer Protocol (TFTP). The difference in the way the CMR-8500 handles updates between FTP and
TFTP is the file is pushed (via the FTP put command) to the CMR-8500.
Because the CMR-8500 requires a reboot during the upgrade process, it is
recommended that this upgrade procedure be performed during scheduled
network down time.
Do NOT remove power from the unit during the download process.
To update the CMR-8500 via FTP (using a Windows PC):
The CMR-8500 FTP server process does not support several FTP client software
programs. When updating a CMR-8500 via FTP from a Windows PC, use the FTP
commands from a command prompt (DOS window) only.
Step Procedure
1 Verify that the “Update To” selection on the Firmware Page is correct (Slot 1, Slot 2, or Oldest).
2 Verify that the “Boot From” selection on the Firmware Page is correct (Slot 1, Slot 2, or Latest).
3 Verify that the update package file is on the PC, or on a network drive accessible from the PC.
4 Open a command prompt (Select “Start”, then “run”, then type in cmd).
5 Open an FTP session to the CMR-8500. Example: “ftp 192.168.1.10 “
6 Set the transfer to binary mode, i.e., issue the “bin” command
7 Use the FTP “put” command to transfer the file. Example: “put cmr-8500-2_0_0.pkg”
8 After the file has transferred successfully, close the FTP session using the “bye” command.
9 Once the update has completed, a reboot of the unit is required.
