Maintenance Mode
When a Signaling Server is placed into Maintenance Mode, the allowable
maximum number of simultaneous firmware downloads increases.
Maintenance Mode enables the UFTP server to utilize most of its processing
resources to deal with the downloads.
The actual number of simultaneous downloads is determined by measuring
the CPU idle time, so each new firmware download session is launched if one
of the following is true:
there are less than five download sessions currently active
Signaling Server or Voice Gateway Media Card is in regular mode (not
in Maintenance Mode) and its CPU usage is less than 85%
Signaling Server is in Maintenance Mode and its CPU usage is less than
100%
and there are less than 100 download sessions for the Signaling Server (or 15
for Voice Gateway Media Card) already taking place.
The UMS tries to launch a pending download session every five seconds.
Note: When Maintenance Mode is enabled, call processing signaling
could be impacted by the UFTP download processes.
Once Maintenance Mode is enabled, it can be exited in several ways:
manually, by using the uftpTurboMode “stop” command
automatically, after the Upgrade Manager is idle for MM minutes after
at least one download has been started
This prevents a time-out from occurring while the system is being
configured and the downloads start. Once a download starts, if MM
minutes pass with no new firmware upgrade jobs starting, the normal
mode of operation resumes. The idle timeout timer is configured using
the uftpTurboModeTimeoutSet command.
automatically, after expiration of the Maintenance Mode period
