ProSafe® 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.
