• Format Now!: This deletes the existing module menu caches. The caches will be recreated
when the next menu client connects.
• Enable: Select this box to enable/disable the menu cache function.

Report if PSUs Missing

When these boxes are enabled, a missing PSU report will be displayed on the Information
pane (see page 39) and logged.
If two power supply units are fitted, in the dual redundancy supply configuration, the Left PSU
and Right PSU items should be selected.
If for some reason one of the power supplies is removed, a warning will be displayed,
indicating which power supply is missing.
If only one power supply is fitted, only the corresponding check box should be selected and
the other cleared.
Note: If a PSU is fitted but fails or is turned off, then a warning message
will always be generated.

Module Upgrades

These controls are used by RollCall and Orbit upgrade systems during upgrade processing.
They are activated automatically, and should not be modified by the user.
PSU Poll Enable
This control enables the polling of PSU to provide information about the operational state of
the PSU. It is provided for system diagnostics, and should only be enabled on a temporary
basis

Comms Fail Restart

These controls affect how the Gateway behaves in the event of communications failure.
The controls are disabled by default. Enable only if instructed to do so by Grass Valley support.
