24- and 48-port Stackable Gigabit PoE L2+ Managed Switches GSM7228PS, GSM7252PS
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)
• 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)
Stack resiliency
Automatic unit replacement (AUR)
• 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
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 • More fl exibility 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 confi guration 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 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.
