Installation Guide
AV Line of Fully Managed Switches
M4250 Series
1. Install the switch using one of the following methods:
• On a at surface. Attach one of the rubber footpads that came with the switch
on each of the four concave spaces on the bottom of the switch.
• In a rack. Except for desktop models, use the rack-mount kit that is supplied with
your switch.
• Attached to a at surface or under a table. For desktop models only, use the
brackets that are supplied with your switch.
2. Apply power.
The Power LED lights solid yellow while the switch conducts a power-on self-test
(POST). After the POST completes, the Power LED indicates the results:
• Solid green. The switch is functional.
• Solid yellow. The POST failed.
If the Power LED does not light at all, check to see that the power cable or power
adapter is plugged in correctly and that the power source is functioning.
3. Connect devices to the switch.
NOTE: If purchased, SFP modules and cables are shipped separately.
We recommend using the following cables and, if applicable, SFP modules:
• Category 5e (Cat 5e) or better cable for a copper port at 1 Gbps or 2.5 Gbps.
• NETGEAR AGM734 module for a copper port at 1 Gbps.
• NETGEARAGM731ForAGM732Fmoduleforaberportat1Gbps.

This switch is designed for indoor use only. If you want to connect it to a device located
outdoors, the outdoor device must be properly grounded and surge protected, and you
must install an Ethernet 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.
NOTE: For information about using the main UI or AV UI, including information
about assigning a static IP address to the switch, see the one of the user manuals,
which you can download by visiting netgear.com/support/download/.

Set up the switch
Prepare the installation site so that mounting, access, power source, and environmental
requirements are met.
Log in and congure the switch
Youcanloginandconguretheswitchthroughtheout-of-band(OOB)port(whichisalso
referred to as the service port), through any Ethernet network port, or through a console
port. By default, the switch functions as a DHCP client.
Tologinandconguretheswitch,useone of the following methods:
• Audio-video local browser user interface: Use the audio-video local browser user
interface, abbreviated as AV UI, through the OOB port or any Ethernet network port
(see AccesstheAVUIormainUItoconguretheswitch).
• Main local browser user interface: Use the main local browser user interface,
abbreviated as main UI, through the OOB port or any Ethernet network port (see
AccesstheAVUIormainUItoconguretheswitch).
• CLI: Use the command-line interface (CLI) through the Type-C USB console port or
RJ-45RS232consoleport.YoucanconguretheIPaddressmanuallyorusethe

• For access over the OOB port, use an IP address in the 192.168.0.0 subnet with
subnet mask 255.255.255.0. For example, use 192.168.0.201.
2. Connect an Ethernet cable from an Ethernet port on your computer to the OOB port
or an Ethernet network port on the switch:
3. Launch a web browser and enter the default IP address of the switch in the address
eldofthebrowser:
• Ethernet port: For access over an Ethernet network port, enter
http://169.254.100.100.
• OOB port: For access over the OOB port, enter http://192.168.0.239.

2. Connect one end of the cable to the appropriate port on the switch and connect the
other end to your computer or terminal.
3. If you connect a computer to a console port on the switch, start a terminal emulation
program:
• On a computer with a Windows operating system, you can use HyperTerminal or
Tera Term.
• On a computer with a Mac operating system, you can use ZTerm.
• On a computer with a Linux operating system, you can use Minicom.

Find the IP address assigned by a DHCP server
By default, the switch functions as a DHCP client and gets its IP address from a DHCP
serverinthenetwork.TondtheassignedIPaddressoftheswitch’sOOBportor
management interface (which can be any of the Ethernet ports), connect a computer or
VT100/ANSI terminal to one of the console ports on the switch.
1. Make sure that the switch is connected to a DHCP server.
2. Set up a console connection with the switch.
For information about setting up a console connection, see Steps 1 through 6
in AccesstheCLItoconguretheswitch. After you are logged in and at the CLI
command prompt, continue with the next step.
3. At the command prompt, do one of the following:
• TondtheIPaddressoftheOOBport(whichisalsoreferredtoastheservice
port), type the show serviceport command, and press Enter.
• TondtheIPaddressofthemanagementinterface,entertheprivilegedEXEC
mode by typing enable, type the show ip management command, and press
Enter.
The IP address that is assigned by the DHCP server displays.
4. Log in to the switch’s AV UI or main UI by launching a web browser and entering
http://<ipaddress>intheaddresseld:
• OOB port: Enter the IP address that is assigned to the OOB port.
• Any Ethernet network port: Enter the IP address that is assigned to the
management interface.
