Primary/Secondary Mode
Only one power supply is needed to power the ION219 chassis; however, there is a second slot to house a
redundant power supply module. If a redundant power supply is used, please note that:
1.
Both power supplies cannot be put in Secondary mode.
2.
If there is only one power supply it will set itself to Primary mode.
3.
The IONPS-D-R1 default setting is Primary mode.
The Primary/Secondary mode is set via the ION software (Web GUI or CLI command). When two IONPS-
D
-R1
modules are installed in an ION chassis, you can select either Primary or Secondary for either or both of the
power supplies via ION software.
The IONPS-D-R1 default setting is Primary mode. A warning message and a control system exist that prevents
both modules from being set to Secondary mode.
Primary
means the IONPS-D-R1 always attempts to provide power to the chassis, and
Secondary
means the
IONPS-D-R1 always attempts to standby, only providing power to the chassis when no other source is providing
sufficient power.
The IONPS-D-R1 is shipped in Primary mode by default, meaning it will always attempt to power the chassis;
if two IONPS-D-R1s are installed in a chassis, they will both attempt to power the chassis, resulting in load-
sharing, with the constant ability for either one to take on the full load of the chassis, should a failure occur.
If you prefer to have primary/secondary operation instead of load-sharing (still maintaining constant fail-over
ability), just change the role of one IONPS-D-R1 from Primary to Secondary.
Power Modules Interoperability Guideline
: If you will be using the older IONPS-A or IONPS-D with the newer
IONPS-A-R1 or IONPS-D-R1 in the same ION219 chassis, then you should place the newer IONPS-A-R1 or IONPS-
D-R1 power supply in the right-hand slot (when facing the back of the ION219 chassis). For more details on the
use of dual power supplies in the ION219 chassis, see the following section.
