Power Supplies
Dell Networking N3024, N3024F and N3048
Dell Networking N3024, N3024F and N3048 switches support two 200-watt
Field Replaceable Unit (FRU) power supplies which give full power
redundancy for the switch. The Dell Networking 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.
Dell Networking N3024P and N3048P
Dell Networking N3024P and N3048P switches support one or two 1100-watt
FRU power supplies. The Dell Networking N3024P switch is supplied with a
single 715-watt power supply (the default configuration) and supports an
additional 1100-watt supply. For the Dell Networking N3048P switch, a single
1100-watt power supply is supplied and another 1100 watt power supply can
be added.
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.
CAUTION: Remove the power cable from the power supplies prior to removing
the power supply module itself. Power must not be connected prior to insertion in
the chassis.
Ventilation System
Two fans cool the Dell Networking N3000 Series switches. The Dell
Networking N3000 Series switches additionally have a fan in each internal
power supply. The Dell Networking N3000 Series fan is field-replaceable.
NOTE: PoE power is dynamically allocated by default. Not all ports will require
the full PoE+ power.
