NETGEAR 8800 Chassis Switch CLI Manual • If all PSUs are enabled then all PSUs must be budgeted at 110V AC to prevent overload of PSUs with 110V AC inputs. OR • If the PSUs with 110V AC inputs are disabled, then the PSUs with 220V AC inputs can be budgeted with a higher output per PSU. The NETGEAR 8800 computes the total available power using both methods and automatically uses the PSU configuration that provides the greatest amount of power to the switch. Table 5 lists combinations where the NETGEAR 8800 maximizes system power by disabling the PSUs with 110V AC inputs. Table 5. PSU Combinations Where 110V PSUs Are Disabled Number of PSUs with 220V AC Inputs Number of PSUs with 110V AC Inputs 2 1 3 1 3 2 4 1 4 2 5 1 For all other combinations of 220V AC and 110V AC PSUs, the NETGEAR 8800 maximizes system power by enabling all PSUs and budgeting each PSU at 110V AC. In addition to the PSU, you can specify the following options: • auto-Specifies that the NETGEAR 8800 determine the enabled or disabled state of the PSU to maximize total system power. This is the default. • on-Specifies that the PSU be enabled even if the NETGEAR 8800 determines it should be disabled. This action may reduce the total available system power and may result in one or more I/O modules powering down. You can override automatic power supply management to enable a PSU with 110V AC inputs that the NETGEAR 8800 disables if the need arises, such as for a planned maintenance of 220V AC circuits. If the combination of AC inputs represents one of those listed in Table 5, you can turn on a disabled PSU using the configure power supply on command. Note: If you override automatic power supply management, you may reduce the available power and cause one or more I/O modules to power down. Chapter 3. Commands for Managing the Switch | 61
