3–23Hub Manager
[9] Downline Upgrade (Cont.)
Select the desired network interface, then press Return. The setup screen displays
the following message:
The device becomes nonfunctional for up to 10 minutes
during the time that the flash load is in progress.
... Press Return Key to Start Load ...
Pressing Return initiates the load over the selected network interface.
After you initiate the process, the setup port screen displays the following message
followed by a series of dots (. . . . . . . .), indicating the downline upgrade is in progress:
DLU process started!
....................................................
During this time, the Hub Status Display displays the following (example) message:
Loading SW from
IP: 16.20.40.155
When the TFTP load transfer is complete, and the TFTP image is verified, the device
becomes nonfunctional and the flash load process begins. (The flash load process
can take up to 4 minutes to complete.)
Note that if you are initiating the load process to a network module, the Hub Manager
firmware attempts to communicate with the module. Because the module is nonfunc-
tional during the flash load process, communications between the module and the
Hub Manager cannot take place. As a result, the Hub Status Display displays the
following message:
4: <module>
unknown
This is normal. The flash load is in progress and takes up to 10 minutes to complete.
Do not interrupt power to the module while the downline load is in progress.
