Frequently Asked Questions
1. What is Multi-Gigabit?
Multi-Gigabit switching uses NBASE-T™ technology to boost the
speed of installed based twisted-pair Cat5e and Cat6 cabling well
beyond the cable’s designed limit of 1 Gigabit per second (Gbps) for
distances up to 100 meters. Capable of reaching 2.5 and 5 Gbps,
Multi-Gigabit RJ45 ports are backward compatible with standard
Gigabit and Fast Ethernet speeds.
2. Why is Multi-Gigabit needed?
As 802.11ac Wave 2 products enter the market capable of wireless
speeds to 2.34 Gbps (up from 1.3 Gbps with Wave 1) in the 5 GHz
band, the limitation will be the majority of Cat5e and Cat6 Ethernet
cables deployed, which currently support a maximum speed of 1 Gbps
over a distance of 100 meters. Customers therefore cannot take full
advantage of 802.11ac Wave 2 deployments without first upgrading
their switch infrastructure. Multi-Gigabit switching allows existing
cables to be used and eliminates the need for entire wired and wireless
rip and replace investment.
3. How to deploy Wave 2 access points?
3x3 and 4x4 radio solutions will swamp a Gigabit LAN; Old access
points required two 1G connections to address this problem. Wave
2 solves this by the use of 2.5G Multi-Gigabit (NBASE-T) LAN ports.
The NETGEAR M4200 is designed to aggregate up to 8 11ac access
points and mount in your plenum; near your APs. And with dual 10G
uplinks (fiber SFP+) the backhaul is convenient, fully non-blocking and
cost eective. Finally its slim design, quiet fans, mounting accessories
and thoughtful cable routing make it unparalleled in mount ability.
4. What is the NBASE-T™ alliance?
The NBASE-T Alliance focuses on building the ecosystem and consensus
required to enable a new 2.5GBASE-T/5GBASE-T Ethernet standard. It
has more than 35 member organizations, including NETGEAR. Although
not a ratified technology, in time this will become an IEEE 802.3bz
standard with a unified implementation approach for all vendors.

5. Why would I invest in the M4200 instead of installing a
more powerful, faster 10G switch?
10GbE switches do not support increments above 1Gbps like multi-
gigabit with 2.5 and 5Gbps on Cat5e and Cat6 cabling, so you would
not get the advantage of 10G potential.
6. What is the PoE+ budget for the M4200?
The M4200-10MG-PoE+ has a power budget of 240W, oering 30W
per port up to 8 ports to support 8 Wave 2 802.11ac 3 x 3 and 4 x 4
access points which require a higher power draw than 802.3af PoE.
7. What is “Easy Mount”?
The M4200-10MG-PoE+ oers a flexible form factor mounting
solution, allowing placement in ceilings (plenum rated), on walls and
inside wiring closets. It comes with a rack mount kit as well as mount
clamps and mount belts for flexible placement.
8. What is the multi-gigabit configuration on the
M4200-10MG-PoE+ switch?
There are 8 ports of multi-gigabit; 6 PoE+ ports oering 100M, 1G
and 2.5G speeds and 2 PoE+ ports oering 100M, 1G, 2.5 and 5GbE
speeds. And with 2 10GbE uplink ports (SFP+ fiber and DAC cables),
the backhaul is convenient, simple and cost eective.
9. Is the switch fabric line-rate for Multi-Gigabit?
M4200-10MG-PoE+ (GSM4210P) oers non-blocking 90Gbps fabric
for (6 x 2.5G) + (2 x 5G) + (2 x 10G) full duplex operation.
10. What are the dimensions of the M4200 switch?
Plenum rated, slim design and mounting accessories allow to place this
switch to optimize access point’s placement and cabling eciency,
inside and outside the rack. The M4200-10MG-PoE+ switch comes in
1U height and 3.94 inches depth (10 cm).
