You can order a second power supply to activate a redundant 1+1 configuration, as shown in the following Figure 18. In redundant configuration, power supplies are "hot-swappable," allowing removal or replacement of one power supply without interrupting appliance operation and network services.
Redundant power supplies share the power load. If one power supply fails, the other automatically assumes the full load and the appliance sends a system alarm. This configuration minimizes the chance of system failure due to failure of an individual power supply.
When a power supply fails for any reason, the Grid Manager displays a power supply alarm. The Grid Status widget on the Dashboard dashboard of the Grid Manager also displays an error. The appliance sends an email notification and reports an SNMP trap. The following Figure 18 figure illustrates the replacement process for an AC power supply:

If the power supply is fully seated, powered on, and operating properly, the LED glows steady greenblue.
