Expansion Slots for Plug-in Modules
One expansion slot is located on the back of the N30xx models and supports the following modules:
•
10GBASE-T module
•
SFP+ module
Each plug-in module has two ports. The plug-in modules include hot-swap support, so rebooting the switch after you install a new module
is not necessary.
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 PSU allows you to use a power cord that has the V-lock feature to create an integral secure
locking connection.
Power Supplies - 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 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 require the full PoE+ power.
CAUTION:
Remove the power cable from the power supplies prior to removing the power supply module itself. You must not
connect power 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.
