Notes:
•
You can install up to two Power Supply modules (Power 1 and Power 2), each
providing an AC power connector on the device's rear panel. The dual power option
provides the device with power redundancy. If both power units are used (for load
sharing - failure protection / redundancy), ensure that you connect each power supply
unit to a different AC supply circuit. For installing the Power Supply modules in the
chassis, see Section
6.1.3 on page 53 .
•
The two AC power sources must have the same ground potential.
•
When the chassis houses two Power Supply modules, you must configure the device
to send an SNMP alarm (acPowerSupplyAlarm) upon a failure or removal of any of
the installed Power Supply modules. For enabling this functionality, use the ini file
parameter, Mediant1000DualPowerSupplySupported. For more information, see the
User's Manual .
