Dell EMC Networking N2100-ON Series Switch
Hardware
This section contains information about device characteristics and modular
hardware configurations for the Dell EMC Networking N2128PX-ON switch.
N2100-ON Series Front Panel
All N2128PX-ON PoE models are 1U, rack-mountable switches. The Dell
EMC Networking N2128PX-ON front panel provides 24 10/100/1000BASE-T
Ethernet RJ-45 ports and four 2.5G NBASE-T Ethernet RJ-45 ports that
support auto-negotiation for speed, flow control, and duplex. NBASE-T
interfaces require auto-negotiation to be enabled. They will not operate
correctly in fixed speed mode. The 2.5G NBASE-T ports support PoE 60W
capability. The N2128PX switch front panel ports operate in full-duplex mode
only. The N2128PX models support two SFP+ 10G ports. The N2128PX-ON
provides one RJ-45 console port for local management and a Type-A USB port
for storage.

The Dell N2128PX-ON switch is capable of loading an OS via the ONIE boot
loader, therefore the port numbering on the front panel labels is consecutive,
per the ONIE requirements, regardless of port type.
For the N2128PX-ON switch, ports 1-24 are 1G interfaces, ports 25-28 are
2.5GBASE-T interfaces, ports 29-30 are 10G interfaces, and rear panel ports
31-32 are HiGig stacking interfaces. NBASE-T interfaces require auto-
negotiation to be enabled. NBASE-T interfaces require auto-negotiation and
will not operate correctly in fixed speed mode.
