NETGEAR GSM7252PS-100NAS warranty Stacking with GSM7328S/GSM7352S/GSM7328FS Note

ProSafe® 24- and 48-port Stackable Gigabit PoE L2+ Managed Switches GSM7228PS, GSM7252PS

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 (configuration
	is instantly updated)
Bi-directional architecture	• Higher stacking throughput capacity with lower latency and jitter for VoIP and video traffic
48 Gigabit local stacking capacity per switch using	• Each switch in the stack understands the shortest path to forward traffic, bi-directionally both up and down
AX742 stacking kit	• Vertical/local stacking and horizontal/distant stacking can be mixed for convenient 10 Gigabit deployments
40 Gigabit distant stacking capacity using AX743 +	(core, distribution layer, edge)
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 configuration
	file is pushed automatically by the stack
Distributed trunking across the stack (link aggregation	• Increased performance with distributed trunks to the core
groups, LACP)	• 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	• More flexibility for device troubleshooting
	• As for a chassis, port mirroring is available from every port to every port across the stack
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
	single switch (Unit 1, Port 2; Unit 2, Port 3, etc.)
	• No configuration required for the VLAN propagation between the switches
Flexible stacking with non-PoE switches	• Stacking with GSM7328S/GSM7352S/GSM7328FS
	• 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 flexible enough to integrate GSM73xxS stack configurations in full Layer 3 mode without L3 License Upgrade.

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

Only the stack master determines the stack configuration/feature set. If the stack master is a GSM73xxS then the entire stack profits from the master L3 configuration.

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 configuration.

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