Dual AC Supply
Dual AC Supply can provide power redundancy for devices, especially those that
may operate in harsher environments. A secondary power supply provides redund-
ancy for the device if one PSU is unplugged or in the event of a failure.
LED Power Status Indicator
The power LED indicator requires no configuration and will display the dual power
status on any Operations Manager device with a dual power supply.
On a device with a
single
PSU (power supply unit)
or
, a
dual
PSU device has
power connected to
two
PSUs, the LED power status indicator should be green at
all times.
If a
dual
PSU device has power connected to
one
PSU (power supply unit), the
LED power status indicator is colored orange indicating that the unit has no redund-
ancy in the event of a power failure.
