NOTE:

Upgrades can be performed through the network using a Management PVC, or through the COM port if Port Use is set to Net Link (see Table 4-23, Ethernet Management Options, in Chapter 4, Configuration Options).

To download software:

1.Initiate an FTP session to the device that you are upgrading.

2.Type bin to enter binary transfer mode.

3.Type hash to enter hash mode if you want to monitor the progress of the upgrade, provided this function is supported by your equipment.

4.Type cd system to change to the system directory.

5.Perform a put of Rxxxxxx.ocd (xxxxxx being the software release number) to the nam.ocd file to start the upgrade.
