Stackable Gigabit PoE L2+ Managed Switches  
Data Sheet  
GSM7228PS, GSM7252PS  
NETGEAR Stackable, PoE Managed Gigabit Switches GSM7228PS and GSM7252PS allow the most exible and easy-to-deploy  
Gigabit Power over Ethernet infrastructure. All the 24 and 48 ports of 10/100/1000 Mbps interfaces support 802.3af PoE standard  
with a comfortable 384 Watts total budget. The rst 8 ports support high power 802.3at PoE+, with up to 30 Watts per port. Four (SFP)  
Gigabit interfaces provide optional ber connectivity for longer reach Gigabit Ethernet requirements. Two built-in 10 Gigabit Ethernet  
SFP+ interfaces on the front, reserved for network uplinks or servers and storage devices, and two 10 Gigabit module bays on the rear,  
permitting both uplinks and local/distant stacking, provide versatile 10 Gigabit deployment possibilities.  
Enterprise-class L2+  
Combining superior resiliency, enterprise-class security and non-blocking performance, NETGEAR Stackable PoE Managed Gigabit  
Switches GSM7228PS and GSM7252PS offer a full set of Layer 2 management features, as well as Layer 2+ (Layer 3 lite – IPv4 routing)  
with unsurpassed affordability. Together with VLAN routing, voice-class prioritization, and chassis-like stack even with local or distant  
non-PoE Layer 3 Gigabit Managed Switches GSM7328S / GSM7352S / GSM7328FS, the GSM7228PS and GSM7252PS series can be  
deployed at enterprise edge, remote branch ofces and closer to the core of small and medium businesses’ growing networks.  
L3 Scalability  
Layer 3 license upgrades GSM7228PL and GSM7252PL unlock IPv4/IPv6 dynamic routing capabilities of GSM7228PS and GSM7252PS.  
Designed for Enterprise networks and core/aggregation levels of SMB networks, L3 upgraded GSM7228PS and GSM7252PS provide  
advanced routing protocols such as OSPF, VRRP and multicast for converged applications.  
High Availability  
NETGEAR Stackable, PoE Managed Gigabit Switches GSM7228PS and GSM7252PS come with a removable power module for the main  
power supply. In the event of a power supply failure, the switch can immediately shift to an external RPS device while the internal power  
module is replaced for 100% uptime. Like all NETGEAR ProSafe Managed Switches, the GSM7228PS and GSM7252PS are backed by the  
NETGEAR ProSafe Lifetime Warranty.

GSM72xxPS/GSM73xxS Stack for Access  
Stacking with L3 Gigabit GSM7328S, GSM7352S and GSM7328FS Managed Switches, the GSM7228PS and GSM7252PS add Power  
over Ethernet access for LAN telephony, wireless access points or IP cameras in a cost-effective solution: the built-in 10 Gigabit SFP+  
ports on the front authorize high performance distributed trunks to the core and management is simplied. In this conguration,  
each stack acts as a single routing switch, with only one GUI/CLI and multiple distributed link aggregations.

GSM72xxPS/GSM73xxS Combining Local Stack (same location, same rack in four locations) and Distant Stack Using 10 Gigabit Fiber  
GSM72xxPS/GSM73xxS Unique Stack  
With GSM7328S, GSM7352S and GSM7328FS Managed Switches, the GSM7228PS and GSM7252PS simplify and lower the cost of  
medium-sized 10 Gigabit deployments. In this conguration, 8 stacked switches build a 384 Gigabit ports network with 16 available  
10 Gigabit ports for servers and high-end storage. The hardware stacking dual-ring topology provides one unique CLI/GUI platform,  
simple management, network and servers/storage perfect resiliency, as well as intelligent load balancing.

Local and Distant Stack Topology  
Local Stack Topology  
AX742  
When the switches are deployed in the same rack, one AX742  
kit per switch is required for dual-ring topology, providing higher  
resiliency and intelligent load balancing.  
24 Gbps Stacking Kit  
Each ring speed is 12 Gbps half duplex (24 Gbps full duplex).  
+
Dual ring overall speed is 24 Gbps half duplex (48 Gbps full  
duplex).  
• Each AX742 kit contains 2 stacking modules+ 1 stacking cable  
• One AX742 kit per switch recommended for full 48 Gbps bandwidth  
and complete redundancy  
Distant Stack Topology  
When the switches are deployed in several locations, two AX743  
SFP+ host modules are required per switch, with the SFP+ optics  
(AXM761, AXM762 or AXM763) for this hardware dual-ring  
topology, providing highest resiliency and intelligent load balancing.  
Each ring speed is 10 Gbps half duplex (20 Gbps full duplex).  
Dual ring overall speed is 20 Gbps half duplex (40 Gbps full duplex).  
Local and distant stack can be combined for maximum exibility  
(example: “SMB Network Deployments” application, Page 3).  
Built-in SFP+ and Stacking Note  
The two built-in SFP+ ports on the front are reserved for network uplinks or  
server/storage connection. For distant stacking using ber, AX743 and the  
rear module bays are preferred.

NETGEAR Hardware Stacking  
Features  
Benefits  
Single IP address management  
Stack up to 8 switches as a single “chassis” logical unit  
One GUI and one CLI managing the whole stack  
The stack acts as a single switch in the network  
The other switches in the network also see the stack as a single switch  
Growth is easy, adding a switch to the stack is as simple as connecting the new unit to the stack (conguration  
is instantly updated)  
Bi-directional architecture  
Higher stacking throughput capacity with lower latency and jitter for VoIP and video trafc  
Each switch in the stack understands the shortest path to forward trafc, bi-directionally both up and down  
48 Gigabit local stacking capacity per switch using  
AX742 stacking kit  
Vertical/local stacking and horizontal/distant stacking can be mixed for convenient 10 Gigabit deployments  
(core, distribution layer, edge)  
40 Gigabit distant stacking capacity using AX743 +  
AXM761/AXM762/AXM763 (SFP+ optics)  
Stack resiliency  
Dual ring architecture ensures that if a switch fails within the stack all the other switches can still communicate  
with one another  
Automatic unit replacement (AUR)  
Adding a new switch to the stack or replacing a failed unit requires no service interruption, the conguration  
le is pushed automatically by the stack  
Distributed trunking across the stack (link aggregation  
groups, LACP)  
Increased performance with distributed trunks to the core  
Greater redundancy using trunking as several switches are connected to the trunk  
(up to 8 ports per trunk – 64 trunks are allowed)  
Many-to-one port mirroring across the stack  
VLANs automatic propagation across the stack  
More exibility for device troubleshooting  
As for a chassis, port mirroring is available from every port to every port across the stack  
As for a chassis, VLAN port tagging or private groups are available everywhere across the stack as for a  
single switch (Unit 1, Port 2; Unit 2, Port 3, etc.)  
No conguration required for the VLAN propagation between the switches  
Stacking with GSM7328S/GSM7352S/GSM7328FS  
Mixing PoE and non-PoE ports into a single logical unit  
Versatile deployment options  
Flexible stacking with non-PoE switches  
Stacking with GSM7328S/GSM7352S/GSM7328FS Note  
Stackable, PoE L2+ Managed Gigabit Switches GSM7228PS and GSM7252PS are exible enough to integrate GSM73xxS stack congurations in full Layer 3 mode without  
L3 License Upgrade.  
When integrating a GSM73xxS stack, the GSM7228PS/GSM7352PS will benet from the Layer 3 stack full feature set, as slaves within the stack.  
Only the stack master determines the stack conguration/feature set. If the stack master is a GSM73xxS then the entire stack prots from the master L3 conguration.  
Without Layer 3 license upgrade, if a GSM7228PS/GSM7252PS becomes the master, then the entire stack will downgrade to Layer 2+ feature set. Unless Layer 2+ is the  
preferred feature set, it is advised to determine in advance which other Layer 3 GSM73xxS slave would become the stack master in case of the stack master failure, by  
specifying the secondary stack master settings in the stack conguration.  
With a Layer 3 license upgrade, a GSM7228PS/GSM7252PS can become the master and handle the full stack L3 conguration.
