Figure 1-1. Dell EMC Networking N2248PX-ON Switch (Front Panel)
N2200-ON Series Rear Panel
The Dell EMC Networking N2200-ON Series back panel has two 40G QSFP
stacking ports in the rear. It also has two slots for power supplies, and two
(N2224X-ON/N2224PX-ON) or three (N2248X-ON/N2248PX-ON) hot-swap
fan trays.
Figure 1-2. Dell EMC Networking N2248PX Switch (Rear Panel)
N2200X-ON Series Switch Ports
The Dell EMC Networking N2200X-ON Series front panel provides 24 or 48
10/100/1000/2500BASE-T Ethernet RJ-45 ports that support auto-negotiation
for speed, flow control, and duplex. Dell EMC Networking N2200X-ON
Series switch front panel 2.5G ports operate in full-duplex at all speeds or
half-duplex at 10/100 Mbps speeds. The Dell EMC Networking N2200X-ON
Series switch models support four 10G/25G SFP28 ports and two 40G QSFP
stacking ports. Dell-qualified transceivers are sold separately.
The front-panel switch ports have the following characteristics:
• The switch automatically detects the difference between crossed and
straight-through cables on RJ-45 ports and automatically chooses the MDI
or MDIX configuration to match the other end.
• The 10/100/1000/2500BASE-T Ethernet RJ-45 ports support full-duplex
mode 10/100/1000/2500 Mbps speeds or half-duplex 10/100 Mbps speeds
on standard Category 5 UTP cable. 2500BASE-T operation requires the
use of auto-negotiation.
• SFP28 ports support Dell-qualified transceivers utilizing 25GBASE-SR,
25GBASE-LR, 25GBASE-CR, 25GBASE-CR-S or 25GBASE-ER
technologies. SFP28 ports support SFP+ fiber transceivers and SFP+
copper twin-ax or DAC technology operating at 10G speeds in full-duplex

6
mode. All four SFP28 ports must be configured to operate at the same
speed. 25GBASE-CR and 10G-BASE-CR modes (copper twin-ax or DAC
cables) require the use of auto-negotiation.
• The default behavior is to log a message and generate an SNMP trap on
insertion or removal of a transceiver that is not qualified by Dell. The
message and trap can be suppressed by using the service unsupported-
transceiver command.
On the N2224X-ON/N2224PX-ON switches, ports 1-12 may be configured to
support 10M/100M half-duplex.
On the N2248X-ON switches, ports 5-36 may be configured to support
10M/100M half-duplex.
N2200-ON SFP28 ports may be configured to operate using SFP+
transceivers using the speed 10000 command for fiber media or the speed
auto 10000 command for copper media. All four SFP28 ports must be
configured to operate at the same speed. A mix of SFP+ and SFP28
transceivers or speeds is not supported. The switch UI does not enforce this
restriction.
N2200-ON Series Console Port
The console port provides serial communication capabilities, which allows
communication using RS-232 protocol. The serial port provides a direct
connection to the switch and allows access to the CLI from a console
terminal connected to the port through the provided serial cable (with RJ-45
YOST to female DB-9 connectors). The console port is separately
configurable and can be run as an asynchronous link from 1200 baud to
115,200 baud. The Dell CLI only supports changing the speed. The defaults
are 115,200 baud rate, 8 data bits, no parity, 1 stop bit, no flow control.

7
Figure 1-3. Dell EMC Networking N2248 Console Port
A separate USB micro type B port is also available for console access to the
CPU CLI. RS-232 emulation over USB is supported on this port. A driver may
need to be installed to support the RS-232 emulation. Only one of the
console ports may be used at a time.
N2200-ON Series USB Port
The Type-A, female USB port supports a USB 3.0-compliant flash memory
drive. The Dell EMC Networking N-Series switch can read or write to a flash
drive with a single partition formatted as FAT-32. Use a USB flash drive to
copy switch configuration files and images between the USB flash drive and
the switch. The USB flash drive may be used to move and copy configuration
files and images to other switches in the network. The system does not
support the deletion of files on USB flash drives. The USB port does not
support any other type of USB device.
N2200-ON Series Reset Button
The reset button is accessed through the pinhole and enables performing a
hard or soft reset of the switch. To reset the switch, insert an unbent paper
clip or similar tool into the pinhole for four seconds. When the switch
completes the boot process after the reset, it resumes operation with the most
recently saved configuration. Any changes made to the running configuration
that were not saved to the startup configuration prior to the reset are lost.

8
To clear the configuration and reset the switch, press the reset button for at
least eight seconds. The saved configuration is cleared and the switch reboots.
The switch then starts the autoconfiguration process.
N2200-ON Series Port and System LEDs
The front panel contains light emitting diodes (LEDs) that indicate the
status of system temperature, port links, power supplies, fans, stacking, and
the overall system status. A locator beacon capability is also present on the
system LEDs. See N2200-ON Series LED Definitions for more information.
N2200-ON Series Stack Master LED and Stack Number Display
When a switch within a stack is the master unit, the stack master LED is solid
green. If the stack master LED is off, the stack member is not the master unit.
The stack number LCD 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
stack master LED is illuminated, and the unit number is displayed.
N2200-ON Series Power Supplies
The Dell EMC Networking N2224X-ON/N2248X-ON switches have a field-
replaceable 550W power supply (DS-550 AC). An additional field-replaceable
power supply may be added to support redundancy.
The Dell EMC Networking N2224PX-ON switches have a field-replaceable
1050-watt power supply (DPS-1050 AC) feeding up to 16x30W PoE and
2x60W devices at full power (712W). The Dell EMC Networking N2248PX-
ON switches have an internal 1050W power supply (DPS-1050 AC) feeding
up to 16x30W PoE devices and 1Xx60W at full power (624W).
In both PoE models, additional field replaceable 1050W, 1300W, or 1600W
power supplies are available to support redundancy or to supply full front
panel demand.

or placed on a flat surface.
Make sure that the chosen installation location meets the following site
requirements:
•Power — The switch is installed near an easily accessible 100–240 VAC,
50–60 Hz outlet.
•Clearance — There is adequate front and rear clearance for operator
access. Allow clearance for cabling, power connections, and ventilation.
•Cabling — The cabling is routed to avoid sources of electrical noise such
as radio transmitters, broadcast amplifiers, power lines, and fluorescent
lighting fixtures.
•Ambient Temperature — The ambient switch operating temperature
range is 0 to 45ºC (32 to 113ºF) at a relative humidity of up to 95 percent,
non-condensing.
NOTE: Decrease the maximum temperature by 1°C (1.8°F) per 300 m (985 ft.) above

Unpacking the N2200 Switch
Package Contents
When unpacking each switch, make sure that the following items are
included:
• One Dell Networking switch
• One RJ-45 to DB-9 female cable
• One rack-mount kit (N2200) for rack installation, two mounting brackets,
bolts, and cage nuts
• One set of self-adhesive rubber pads for the free-standing switch (four pads
are included)
Unpacking Steps
NOTE: Before unpacking the switch, inspect the container and immediately report
any evidence of damage.
1 Place the container on a clean, flat surface and cut all straps securing the
container.
2 Open the container or remove the container top.
3 Carefully remove the switch from the container and place it on a secure
and clean surface.
4 Remove all packing material.
5 Inspect the product and accessories for damage.
Rack Mounting a N2200 Switch
WARNING: Read the safety information in the Safety and Regulatory Information
as well as the safety information for other switches that connect to or support the
switch.
The AC power connector is on the back panel of the switch.
Installing in a Rack
WARNING: Do not use rack mounting kits to suspend the switch from under a
table or desk, or attach it to a wall.

15
CAUTION: Disconnect all cables from the switch before continuing. Remove all
self-adhesive pads from the underside of the switch, if they have been attached.
CAUTION: When mounting multiple switches into a rack, mount the switches
from the bottom up.
1 Place the supplied rack-mounting bracket on one side of the switch,
ensuring that the mounting holes on the switch line up to the mounting
holes in the rack-mounting bracket. Figure 1-5 illustrates where to mount
the brackets.
Figure 1-5. Attaching the Brackets
2 Insert the supplied bolts into the rack-mounting holes and tighten with a
screwdriver.
3 Repeat the process for the rack-mounting bracket on the other side of the
switch.
4 Insert the switch into the 48.26 cm (19 inch) rack, ensuring that the rack-
mounting holes on the switch line up to the mounting holes in the rack.
5 Secure the switch to the rack with either the rack bolts or cage nuts and
cage-nut bolts with washers (depending on the kind of rack you have).
Fasten the bolts on bottom before fastening the bolts on top.
CAUTION: Make sure that the supplied rack bolts fit the pre-threaded holes in the
rack.
NOTE: Make sure that the ventilation holes are not obstructed.

16
Installing as a Free-standing Switch
NOTE: We strongly recommend mounting the switch in a rack.
Install the switch on a flat surface if you are not installing it in a rack. The
surface must be able to support the weight of the switch and the switch
cables. The switch is supplied with four self-adhesive rubber pads.
1 Attach the self-adhesive rubber pads on each location marked on the
bottom of the switch.
2 Set the switch on a flat surface, and make sure that it has proper
ventilation by leaving 5 cm (2 inches) on each side and 13 cm (5 inches) at
the back.
Stacking Multiple N2200 Switches
You can stack N2200 switches up to 12 switches high using the QSFP ports
located on the rear of the switch. N2200 switches support stacking only with
other N2200 series switches. When multiple switches are connected together
through the stack ports, they operate as a single unit with up to 576 front
panel ports. The stack operates and is managed as a single entity.
NOTE: If you are installing a stack of switches, you need to assemble and cable the
stack before powering up and configuring it. When a stack is powered up for the
first time, the switches elect a Master Switch, which may occupy any location in
the stack. The Master LED on the front panel is illuminated on the master unit.
Creating a Switch Stack
Create a stack by connecting adjacent units using the QSFP stacking ports on
the back panel of the switch. Figure 1-6 on page 17 shows the switches
connected in a ring topology, which is the recommended topology for a stack.
1 Connect one of the QSFP cables into either of the stacking ports of the
top switch and the switch directly below it.
If necessary, use a separately purchased, longer (1 meter or 3 meter) QSFP
cable to connect the switches.
2 Repeat this process until all of the devices are connected.
3 Use the remaining stacking cable to connect the two remaining stacking
ports together so that a ring topology is assembled.

17
Figure 1-6. Connecting a Stack of Switches
The stack in Figure 1-6 is connected in a ring topology and has the following
physical connections between the switches:
• The bottom QSFP port on Unit 1 is connected to the top QSFP port on
Unit 2.
• The bottom QSFP port on Unit 2 is connected to the top QSFP port on
Unit 3.
• The bottom QSFP port on Unit 3 is connected to the top QSFP port on
Unit 1.
Stacking Standby
The stacking feature supports a Standby or backup unit that assumes the
Master unit role if the Master unit in the stack fails. As soon as a Master
failure is detected in the stack, the Standby unit initializes the control plane
and enables all other stack units with the current configuration. The Standby
unit maintains a synchronized copy of the running configuration for the
stack. The Standby unit is automatically selected in the stack; however, you
can use the CLI to select a different stack member as Standby. See the User’s
Configuration Guide or the CLI Reference Guide for more information.
