Introduction

This document provides basic information about the Dell®EMC™

Networking N2200 Series switches, including how to install a switch and

perform the initial configuration. For information about how to configure and

monitor switch features, see the User’s Configuration Guide, which is

available on the Dell Support website at

dell.com/support/manuals

, for the

latest updates on documentation and firmware.

This document contains the following sections:

• N2200 Series Overview

• N2200 Series Hardware Overview

• N2200 Installation

• Starting and Configuring the N2200 Switch

NOTE: Switch administrators are strongly advised to maintain Dell EMC

Networking switches on the latest version of the Dell EMC Networking Operating

System (DNOS). Dell EMC Networking continually improves the features and

functions of DNOS based on feedback from you, the customer. For critical

infrastructure, prestaging of the new release into a noncritical portion of the

network is recommended to verify network configuration and operation with the

new DNOS version.

N2200 Series Hardware Overview

Dell EMC Networking N2200-ON Series Switch

Hardware

This section contains information about device characteristics and modular

hardware configurations for the Dell EMC Networking N2200 Series

switches.

N2200-ON Series Front Panel

The Dell EMC Networking N2224X-ON/N2224PX-ON/N2248X-

ON/N2248PX-ON switch front panels include the following features:

• 24 or 48 RJ-45 10/100/1000/2500BASE-T ports

• Four SFP28 10G/25GBASE-X ports

• Two QSFP 40G stacking ports

• RJ-45 and Type-B micro USB 3.0 console ports

• Reset button

• Port and system LEDs

• Stack Master LED and Stack Number Display

• Type-A USB 3.0 port for storage

• Out-of-band Ethernet interface

The following images show a representative front panel of the Dell EMC

Networking switch.

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

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.

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.

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.
