Power supply
The N3200-ON Series switch ships with one pluggable AC power supply with airflow from the I/O-side to the PSU-side of the switch. You
can order a second AC PSU separately. If you require DC power, you can order one or two DC power supply units. The N3248PXE-ON
requires two DC power cables; the N3248P-ON requires one DC power cable.
N3248PXE-ON and N3248P-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 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.
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.

Components
For the N3200-ON Series switches, power supply 1 (PSU1) and power supply 2 (PSU2) are on the right side of the switch.
N3248P-ON and N3248PXE-ON PSUs
1. Default PSU and ordered-separately PSU. PSU1 is near the center of the switch; PSU2 is on the right edge of the switch.
The PSU has an integrated fan, which you cannot replace individually; if the fan integrated in a PSU fails, you must replace the entire PSU.
WARNING:
Prevent exposure and contact with hazardous voltages. Do not attempt to operate this switch with the
safety cover removed.
CAUTION:
Remove the power cable from the PSU before removing the PSU. Also, do not connect the power cable
before you insert the PSU in the switch.
NOTE:
To comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC or DC Power Ports, use an
external surge protection device (SPD) at the AC or DC input of the router.
