Port and System LEDs
The front panel contains light emitting diodes (LEDs) that indicate the
status of port links, power supplies, fans, stacking, and the overall system
status. See "N2100-ON Series LED Definitions" on page 141 for more
information.
LED of Management Unit in Stack and Stack Number Display
When a switch within a stack is the primary unit, the LED of the
management unit in the stack is solid green. If the LED of the management
unit in the stack is off, the stack member is not the primary unit. The Stack
No. panel displays the unit number for the stack member. If a switch is not
part of a stack (in other words, it is a stack of one switch), the LED of the
management unit in the stack is illuminated, and the unit number is
displayed.
N2100-ON Series Back Panel
The N2128PX-ON has two 21G stacking ports in the rear that accept mini-
SAS connectors. It also has a 16-pin connection for a modular power supply
(Dell MPS1000) supporting an additional 1000W of power.

The Dell EMC Networking N2128PX-ON switch has an internal 715-watt
power supply feeding up to 16 PoE devices at full PoE+ power (500W).

switches.
