Using Maintenance Mode
Some operations (such as downloading out-of-band) can only be done when the 8265 is in Maintenance
mode.
This mode is entered when the MAINTAIN command is issued when logged in with Administrator mode
(from a local session via the RS-232 console port).
When the command is issued, the CPSW is reset. You should stop all traffic before issuing the command.
Changes made during the Administrator mode session should be saved prior to issuing the MAINTAIN
command, or they will be lost. If you have made changes, but do not wish to keep them, you need to
issued the comand MAINTAIN FORCE to enter Maintenance mode.
When Maintenance mode is active, the ATM prompt appears as
>>
and the System Status LCD on the
CPSW module displays the message: "MAINTENANCE MODE ENTERED UPON USER REQUEST".
Table 1 provides a summary of the commands available in Maintenance mode. For details of each
command, refer to the
IBM 8265 Command Reference Guide.
