1. Versatile, Protected and Expendable Power

The M4100 series are the ﬁrst aordable managed switches with

both redundant and external power supply capabilities - key for critical

applications such as VoIP, IP surveillance and Wireless access points.

PoE devices gobble increasing amounts of PoE power, yet existing

SMB switching solutions from other vendors don’t scale to full power.

Although most servers in SMB networks have dual power supplies,

switches in SMB networks have not – until now.

Select desktop switches in the M4100 series can be powered by PoE

as a cost-eective solution when there is no existing electrical wiring or

power outlets, as the switch can draw power directly from the wiring

closet.TheexibilityofaPoEswitchisalsoconvenientformeeting

rooms and open spaces where visible electrical wiring is unsightly or

impractical. One PoE+ downlink (30W) from the upstream switch

issucientforthestandardoperationoftheM4100-D12Gand

M4100-D12G-POE+ switches. This also increases resiliency for critical

installations: the Power over Ethernet PD connection on these switches

also doubles as a redundant power supply (RPS) should the switch be

locally powered.

Innovative PoE passthrough technology even lets M4100-D12G-

POE+ power local PoE PD devices - redistributing PoE budget from

the upstream switch. Up to 25W of power can be available for local

PD devices - extending the reach of PoE deployments beyond the

100-meter or 328-feet bar: the M4100-D12G-POE+ can function

as a “PoE repeater” for powering remote IP cameras, Wireless access

points, etc.

For all other rackmount Power over Ethernet models in the NETGEAR

Intelligent Edge M4100 series, in addition to their built-in PSU providing

more PoE power than competitive solutions at a similar price point, the

NETGEAR Intelligent Edge M4100 series is the only one allowing for an

additional PoE power “upgrade” via external power supply; immediately

or at later times.

Short story, all rackmount switches in the NETGEAR M4100 series are

either PoE Full Power capable already or PoE Full Power capable when

drawing external power from the RPS4000. All 24-port and 48-port

models can scale up to 802.3af PoE full power or 802.3at PoE+ full

power simultaneously for all ports. This is real investment protection.

2. Security and Control

Enhanced security includes network access control and isolation for

improved convergence of voice, video and data: dynamic 802.1x VLAN

assignment mode, including Dynamic VLAN creation mode and Guest

VLAN / Unauthenticated VLAN are supported for rigorous user and

equipmentpolicyenforcementfromaRADIUSserver.TheRADIUS

server can also be the Network Policy Server (NPS) in Microso®

Windows Server™ 2008 or 2012, when in an Active Directory domain.

Up to 48 clients (802.1x) per port are supported, including the

authentication of a user’s domain, in order to facilitate convergent

deployments. When IP phones connect PCs on their bridge, IP phones

and PCs authenticate on the same switch port but under dierent

VLAN assignment policies (Voice VLAN versus data VLAN) - providing

administratorswithgreaterexibilityduringdeploymentandpolicy

enforcement.

For 802.1x unaware clients, 802.1x MAC Address Authentication

Bypass (MAB) is a great alternative: when 802.1x unaware clients try

to connect, the switch sends their MAC addresses to the authentication

server. When checked, the RADIUS server returns the access policy and

VLAN assignment to the switch for each client.

Enhanced security also includes better network isolation with Private

VLANs, providing Layer 2 isolation between ports that share the same

broadcast domain. A VLAN broadcast domain can be partitioned into

smaller point-to-multipoint subdomains across switches in the same

Layer 2 network. This is useful for IP camera deployments, or in the

DMZ when servers are not supposed to communicate with each other

but need to communicate with a router. Private VLANs remove the

need for more complex port-based VLANs with respective IP interface/

subnets and associated L3 routing.

3. Reliability

Learn how the NETGEAR M4100 series delivers more for less: all models

provide much longer MTBF (average lifetime) thanks to better/higher

qualitycomponentsandcircuitry.

For instance, the desktop 8-port PoE Fast Ethernet M4100-D10-

POE (FSM5210P) is predicted to have an average mean time between

failure of 579,985 hours, or 66 years at an ambient standard 25°C

temperature (77°F). The rackmount 24-port PoE Gigabit Ethernet

M4100-26G-POE (GSM7226LP) is to predicted to have an average

mean time between failure of 437,199 hours, more than 49 years. This

is nearly double the reliability of the closest competitive solutions in this

price band.

Conclusion

The M4100 series delivers an unbeatable combination of performance,

security and convergence for voice, video and data networking solutions.

Due to the wide adoption of virtualization, the convergence of voice,

video, and data and the rapid proliferation of bandwidth-intensive

applications, small and mid-sized businesses, hospitals and schools

today have security, control and reliability needs similar to those of large

enterprises. For approximately the same price as low-end solutions

currently on the market aimed at SMBs, NETGEAR is oering high-

end features that have so far been reserved only for enterprise-class

oerings available at double or triple the price point.
