Power Distribution According To Number Of Installed Power Supplies - Enterasys G3G124-24 Hardware Installation Manual

Power Supply Installation Considerations
By default, the G3 switch automatically allots power to the base board and to each installed
module. Each component's power consumption is subtracted from the available power and the
remaining power is equally distributed among installed PoE modules. A PoE module must be
allotted a minimum of 37 watts to be operational.
Table 2‐1 illustrates the G3 power distribution. If one power supply fails or is removed (hot
swapped) for any reason, the other power supply takes up the load. Power redundancy remains in
effect as long as the load does not exceed the power as stated in the Redundancy column.

1. If power requirements exceed this capacity, power redundancy is no longer supported. Removing a power
supply under this condition will cause the remaining power supplies to go into over-current protection and shut
down the power system.
Power supply LEDs visible on the front panel of the switch indicate whether the power supplies
are present and, if two are present, whether they are in redundant or additive (non‐redundant)
mode. For more information about the power supply LEDs, see "Power LED Displays" on
page 2‐14.
Refer to Appendix
the CLI to set the status of power redundancy and to review system power settings, refer to the
Enterasys G‐Series CLI Reference.
