N2200-ON Series Power Supplies
The Dell EMC Networking N2224X-ON/N2248X-ON switches have a field-
replaceable 550W power supply (DS-550 AC). An additional field-replaceable
power supply may be added to support redundancy.
The Dell EMC Networking N2224PX-ON switches have a field-replaceable
1050-watt power supply (DPS-1050 AC) feeding up to 16x30W PoE and
2x60W devices at full power (712W). The Dell EMC Networking N2248PX-
ON switches have an internal 1050W power supply (DPS-1050 AC) feeding
up to 16x30W PoE devices and 1Xx60W at full power (624W).
In both PoE models, additional field replaceable 1050W, 1600W, or 2000W
power supplies are available to support redundancy or to supply full front
panel demand. The N2224PX-ON and N2248PX-ON models also support an
EPS external power supply in the rear for redundant or shared power
operation. The EPS should not be configured as the primary power supply.
Rebooting the switch or powering up the switch when the EPS is the only
power supply is not supported. Ensure that an internal power supply is
present and powered prior to performing switch maintenance. When using
the EPS, always connect the power to the A (left) connector. EPS power is not
available to the switch if the only EPS power connection is to the B
connector.
