Installation Guide

Power supply
The N3200-ON Series switch ships with one pluggable AC power supply. You can order a second AC PSU separately. If you
require DC power, you can order one or two DC PSUs.
The N3224PX-ON, N3248P-ON, and N3248PXE-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. To install an external power supply, see the External Power Supply (EPS) Installation for the Dell EMC
PowerSwitch N2200-ON and N3200-ON Series Switches at www.dell.com/support.

CAUTION: To prevent electrical shock, ensure that the N3200-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: Reserve airflow, from the PSU-side to the I/O-side of the switch, is only supported on the N3224T-ON, N3248X-
ON, and N3248TE-ON 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 N3200-ON Series switch and components.
