eSeries Sound Hardware Power Management

Applies to: MMS-5e, MMS-3e

MMS-3e and MMS-5e devices running firmware 6.6.20230705.0/7.2.20230705.0 will, by default, reduce power consumption by powering down non-essential hardware after periods of inactivity. This is enabled by default but can be disabled by opening a telnet session to port 23 and sending:

Subsequently, the functionality can be re-enabled by sending:

The MMS must meet the following conditions for power management to occur:

• There must not have been any activity on the system configuration page within the past 60 seconds

• There must have been no new control connections within the past 15 minutes

• There must have been no browse activities from any existing control connection within the past 15 minutes

• There must not be any pending schedules within the next 10 minutes

• There must not be any active playback on any output managed by the dedicated sound hardware.

  • MMS-3e: Player A and Player B

  • MMS-5e: Player A through Player D

Additionally, it can be elected that an MMS will disable its sound hardware entirely. This is useful in systems that depend entirely on eAudioCast for audio transmission where the sound hardware is not used. This option is only available to systems with configured Autonomic Amplifiers. To toggle this behavior:

1. Visit the System tab of the configuration page for the MMS in question, found at http://ipOfMMS/Config/System.html

2. Click the blue pencil for the specific MMS to edit its settings

3. Toggle the Physical Outputs setting from AUTO to OFF

In MMSOS 6.6.20240212.0/7.2.20240212.0 or greater only:

To default the MMS back to an unset state as if this flag had never been set such that any automatic behavior is restored, send:
