AV Line of Fully Managed Switches M4250 Series

Introduction

The NETGEAR AV Line of Fully Managed Switches M4250 Series consists of

high-performance, IEEE-compliant, professional audio-video switches for audio over IP

and small as well large-scale video over IP, including LED tile-based video walls.

Depending on the model, the switch supports 1 Gbps, 2.5 Gbps, and 10 Gbps

multispeed ports for Ethernet connections, including PoE+ and PoE++ connections,

and SFP+ ports for 1 Gbps and 10 Gbps fiber connections.

In this guide, the AV Line of Fully Managed Switches M4250 Series is referred to as the

switch.

This hardware installation guide complements the installation guide that came with the

switch.

This chapter serves as an introduction to the switch and includes the following sections:

• Overview

• Features

• Safety instructions and warnings

Note: For more information about the topics that are covered in this manual, visit the

support website at netgear.com/support.

Note: For switch documentation, including the user manual, the command-line interface

manual, and the data sheet, visit netgear.com/support/product/M4250.aspx#docs.

Overview

This installation guide is for the following NETGEAR AV Line of Fully Managed Switches

M4250 Series models:

•8-port PoE+ and PoE++ models:

-M4250-10G2F-PoE+. Eight PoE+ (802.3at) 1GBASE-T RJ-45 ports, two 1GBASE-T

RJ-45 ports, and two 1G SFP fiber uplink ports. The total PoE budget for the

switch is 125W.

-M4250-10G2XF-PoE+. Eight PoE+ (802.3at) 1GBASE-T RJ-45 ports, two

1GBASE-T RJ-45 ports, and two 10G SFP+ fiber uplink ports. The total PoE budget

for the switch is 240W.

-M4250-10G2XF-PoE++. Eight PoE++ (802.3bt) 1GBASE-T RJ-45 ports, two

1GBASE-T RJ-45 ports, and two 10G SFP+ fiber uplink ports. The total PoE budget

for the switch is 720W.

•LED tiles model with 2.5 Gbps ports:

M4250-12M2XF. Twelve 2.5GBASE-T RJ-45 ports and two 10G SFP+ fiber uplink

ports.

•Aggregation model with multiple 10G SFP+ fiber ports:

M4250-16XF. Sixteen 1G/10G SFP+ fiber ports.

The switch lets you create high-speed connections to a server or network backbone.

For example, you can do the following:

•Connect switches to each other with high-speed links

•Link to high-speed servers

•Provide 10M/100M/1G/2.5G copper and 1G/10G fiber connectivity

You would typically rack-mount the switch in a wiring closet or equipment room as a

standalone switch. The switch is IEEE compliant and offers low latency for high-speed

networking. All ports can automatically negotiate to the highest speed, which makes

the switch also suitable for AV environments with a mix of 1 Gbps and 2.5 Gbps Ethernet

devices and 1G and 10G fiber connections. With the exception of the ports on model

M4250-12M2X, the copper ports that support 10 Mbps and 100 Mbps ports can operate

in half-duplex or full-duplex mode. For 1 Gbps and 2.5 Gbps connections, the copper

ports always operate in full-duplex mode.

Safety instructions and warnings

Use the following safety guidelines to ensure your own personal safety and to help

protect your system from potential damage.

To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment,

observe the following precautions:

•This product is designed for indoor use only in a temperature-controlled and

humidity-controlled environment. For more information, see the environmental

specifications in the appendix or the data sheet.

Note the following:

-If you want to connect the switch to a device located outdoors, the outdoor device

must be properly grounded and surge protected, and you must install an Ethernet

Hardware Installation Guide8Introduction

surge protector inline between the switch and the outdoor device. Failure to do

so can damage the switch.

-Before connecting this switch to outdoor cables or devices, see

https://kb.netgear.com/000057103 for safety and warranty information.

-Failure to follow these guidelines can result in damage to your NETGEAR product,

which might not be covered by NETGEAR’s warranty, to the extent permissible

by applicable law.

•Observe and follow service markings:

- Do not service any product except as explained in your product documentation.

Some devices should never be opened.

-If applicable to your product, opening or removing covers that are marked with

the triangular symbol with a lightning bolt can expose you to electrical shock.

We recommend that only a trained technician services components inside these

compartments.

•If any of the following conditions occur, unplug the product from the power outlet

and replace the part or contact your trained service provider:

- Depending on your product, the power adapter, power adapter cable, power

cable, extension cable, or plug is damaged.

-An object fell into the product.

- The product was exposed to water.

- The product was dropped or damaged.

-The product does not operate correctly when you follow the operating

instructions.

•Keep your product away from radiators and heat sources. Also, do not block cooling

vents.

•Do not spill food or liquids on your product components, and never operate the

product in a wet environment. If the product gets wet, see the appropriate section

in your troubleshooting guide, or contact your trained service provider.

•Do not push any objects into the openings of your products. Doing so can cause

fire or electric shock by shorting out interior components.

•Use the product only with approved equipment.

•If applicable to your product, allow the product to cool before removing covers or

touching internal components.

Hardware Installation Guide9Introduction

AV Line of Fully Managed Switches M4250 Series

•Operate the product only from the type of external power source indicated on the

electrical ratings label. If you are not sure of the type of power source required,

consult your service provider or local power company.

•To avoid damaging your product, if your product uses a power supply with a voltage

selector, be sure that the selector is set to match the power at your location:

-115V, 60 Hz in most of North and South America and some Far Eastern countries

such as South Korea and Taiwan

- 100V, 50 Hz in eastern Japan and 100V, 60 Hz in western Japan

-230V, 50 Hz in most of Europe, the Middle East, and the Far East

•Be sure that attached devices are electrically rated to operate with the power available

in your location.

•Depending on your product, use only a supplied power adapter or approved power

cable:

If your product uses a power adapter:

-If you were not provided with a power adapter, contact your local NETGEAR

reseller.

-The power adapter must be rated for the product and for the voltage and current

marked on the product electrical ratings label.

If your product uses a power cable:

-If you were not provided with a power cable for your system or for any

AC-powered option intended for your system, purchase a power cable approved

for your country.

-The power cable must be rated for the product and for the voltage and current

marked on the product electrical ratings label. The voltage and current rating of

the cable must be greater than the ratings marked on the product.

•To help prevent electric shock, plug the system and peripheral power cables into

properly grounded power outlets.

•If applicable to your product, the peripheral power cables are equipped with

three-prong plugs to help ensure proper grounding. Do not use adapter plugs or

remove the grounding prong from a cable. If you must use an extension cable, use

a three-wire cable with properly grounded plugs.

•Observe extension cable and power strip ratings. Make sure that the total ampere

rating of all products plugged into the extension cable or power strip does not

exceed 80 percent of the ampere ratings limit for the extension cable or power strip.
