Hardware Installation Guide6Introduction
AV Line of Fully Managed Switches M4250 Series

•Special models:
-M4250-12M2XF: LED tiles model with 2.5 Gbps ports. Twelve 2.5GBASE-T RJ-45
ports and two 10G SFP+ fiber uplink ports.
-M4250-16XF: Aggregation model with multiple 10G SFP+ fiber ports. 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.
Features
The switch supports the following key hardware features:
•PoE+ and PoE++ models with switch ports in various configurations depending on
the model:
- 8, 24, or 40 PoE+ or PoE++ ports, depending on the model
-Up to four 1GBASE-T RJ-45 ports (also supporting 10M and 100M speeds),
depending on the model
-Up to eight 1G SFP or 10G SFP+ fiber uplink ports, depending of the model
-PoE budget from 125W to 2880W, depending on the model
•LED tiles model with twelve 2.5GBASE-T RJ-45 ports (also supporting 1G and 100M
speeds) and two 10G SFP+ fiber ports
•Aggregation model with sixteen 1G/10G SFP+ fiber ports
•Support for switching fabric up to 320 Gbps, depending on the model, with all ports
at line-rate.

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
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.
