Power Supplies

N3024, N3024F and N3048
N3024, N3024F and N3048 switches support two 200-watt Field Replaceable
Unit (FRU) power supplies which give full power redundancy for the switch.
The N3024, N3024F and N3048 switches offer the V-lock feature for users
desiring the need to eliminate accidental power disconnection. The V-lock
receptacle on the Power Supply Unit (PSU) allows for the use of a power cord
that has the V-lock feature to create an integral secure locking connection.
N3024P and N3048P
Dell Networking N3024P and N3048P switches support one or two 1100-watt
FRU power supplies. The N3024P switch comes with a single 715-watt power
supply (the default configuration), and supports either one or two 1100-watt
supplies. For the N3048P switch, an 1100-watt power supply is the default
configuration.
A single 1100-watt power supply can feed up to 24 PoE devices at full PoE+
power (950W). Dual-equipped switches will feed up to 48 PoE devices at full
PoE+ power (1800W), as well as provide power supply redundancy.
NOTE:
PoE power is dynamically allocated. Not all ports will require the full PoE+
power.
CAUTION:
the power supply module itself. Power must not be connected prior to insertion in
the chassis.

Ventilation System

Two fans cool the N30xx switches. The N30xx switches additionally have a
fan in each internal power supply. The N30xx fan is a FRU.
