ProSafe® 24- and 48-port Stackable Gigabit PoE L2+ Managed Switches Data Sheet

GSM7228PS, GSM7252PS

NETGEAR Stackable, PoE Managed Gigabit Switches GSM7228PS and GSM7252PS allow the most ﬂ 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 ﬁ rst 8 ports support high power 802.3at PoE+, with up to 30 Watts per port. Four (SFP) Gigabit interfaces provide optional ﬁ 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 ofﬁ ces 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.

NETGEAR Hardware Stacking

Local and Distant Stack Topology

Local Stack Topology

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.

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).

AX742 24 Gbps Stacking Kit

• 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).

AX743 SFP+ Host Module

Local and distant stack can be combined for maximum ﬂ 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 ﬁ ber, AX743 and the

rear module bays are preferred.

AXM761, AXM762 or AXM763 SFP+ 10GBase-SR, LR or LRM optics

• AX743 + AXM761/AXM762/AXM763 optics in each rear slot

• Two SFP+ modules are recommended for full 40 Gbps bandwidth and complete redundancy

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 (conﬁ guration is instantly updated)

Bi-directional architecture

48 Gigabit local stacking capacity per switch using AX742 stacking kit

40 Gigabit distant stacking capacity using AX743 + AXM761/AXM762/AXM763 (SFP+ optics)

Stack resiliency

Automatic unit replacement (AUR)

Distributed trunking across the stack (link aggregation groups, LACP)

Many-to-one port mirroring across the stack • More ﬂ exibility for device troubleshooting

VLANs automatic propagation across the stack • As for a chassis, VLAN port tagging or private groups are available everywhere across the stack as for a

Flexible stacking with non-PoE switches • Stacking with GSM7328S/GSM7352S/GSM7328FS

• Higher stacking throughput capacity with lower latency and jitter for VoIP and video trafﬁ c

• Each switch in the stack understands the shortest path to forward trafﬁ c, bi-directionally both up and down

• Vertical/local stacking and horizontal/distant stacking can be mixed for convenient 10 Gigabit deployments (core, distribution layer, edge)

• Dual ring architecture ensures that if a switch fails within the stack all the other switches can still communicate with one another

• Adding a new switch to the stack or replacing a failed unit requires no service interruption, the conﬁ guration ﬁ le is pushed automatically by the stack

• 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)

• As for a chassis, port mirroring is available from every port to every port across the stack

single switch (Unit 1, Port 2; Unit 2, Port 3, etc.)

• No conﬁ guration required for the VLAN propagation between the switches

• Mixing PoE and non-PoE ports into a single logical unit

• Versatile deployment options

Stacking with GSM7328S/GSM7352S/GSM7328FS Note

Stackable, PoE L2+ Managed Gigabit Switches GSM7228PS and GSM7252PS are ﬂ exible enough to integrate GSM73xxS stack conﬁ gurations in full Layer 3 mode without

L3 License Upgrade.

When integrating a GSM73xxS stack, the GSM7228PS/GSM7352PS will beneﬁ t from the Layer 3 stack full feature set, as slaves within the stack.

Only the stack master determines the stack conﬁ guration/feature set. If the stack master is a GSM73xxS then the entire stack proﬁ ts from the master L3 conﬁ guration.

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 conﬁ guration.

With a Layer 3 license upgrade, a GSM7228PS/GSM7252PS can become the master and handle the full stack L3 conﬁ guration.
