Power supply
The N2200-ON Series switch ships with one hot-swappable AC power supply.
You can order a second AC PSU separately. If you require DC power, you can order one or two DC power supply units.
● N2224X-ON and N2248X-ON—AC with airflow from the I/O side to the PSU side or airflow from the PSU side to the I/O
side
● N2224PX-ON and N2248PX-ON—AC with airflow from the I/O side to the PSU side
The N2224PX-ON and N2248PX-ON switches also support an optional external power supply that connects to the switch using
an MPS-1S or MPS-3S shelf. Use the EPS to add redundancy or extend the PoE budget based on your requirement.

CAUTION: To prevent electrical shock, ensure that the N2200-ON Series switch is grounded properly. If you do
not ground your equipment correctly, excessive emissions may result. Use a qualified electrician to ensure that
the power cables meet your local electrical requirements.
WARNING: Equipment that provides DC input to the DC port must be certified for CCC and meet the relevant
standards.
NOTE: Reverse airflow is only supported on the N2224X-ON and N2248X-ON AC switches.
NOTE: Connect the power supply to the appropriate branch circuit protection as defined by your local electrical codes.
Verify that the remote power source complies with the switch input power specifications.
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the N2200-ON Series switch and components.
