Ethernet Routing Switch 4900

Next-generation, high-performance, feature-rich Ethernet

Switch platforms speciﬁcally optimized for the Wiring Closet

demands of the mainstream Enterprise. Extreme Ethernet

Routing Switch 4900 products deliver the agility to perform

equally in conventional IP and Ethernet Fabric-based

networking solutions.

The Ethernet Routing Switch 4900 products leverage the latest advances in

network switching architecture design to maximize hardware performance

and software capability. These products represent a clear evolutionary step

for the Ethernet Routing Switch 4000 Series, particularly in terms of

value and future-ready ﬂexibility, and have been optimized for the

Enabled Edge role.

The primary purpose of a network is to interconnect users with their

applications, and the best networks do this reliably, eciently, and with

a high degree of agility. Extreme’s Fabric-Based architecture empowers

companies to extend the virtualized Ethernet Fabric beyond the Data

Center, to the very edge of the network, delivering powerful integration of

users, applications, and devices.

The new Ethernet Routing Switch 4900 (ERS 4900) products are an

important part of this strategy, integrating Fabric Connect capabilities into

a form-factor that is cost-eective, ﬂexible, and reliable. The ERS 4900

products can be deployed standalone, or conﬁgured as a Stackable Chassis

system of up to eight units/400 ports, supported by up to 416Gbps of

virtual backplane bandwidth.

ERS 4900 Stackable Chassis Rear View ERS 4926 GTS ERS 4926 GTS-PWR+ The Extreme Stackable Chassis technology can offer the same performance, resiliency, and ease of serviceability attributes of a traditional Chassis solution, but at a lower, pay-as-you-grow price point. Notable is the ability to swapout an individual failed unit without the requirement to preor post-stage operating system software or configuration; providing equivalency to module replacement for a modular Chassis system.

The 26-port models – ERS 4926GTS and ERS 4926GTSPWR+ – feature 24 1000BASE-T Gigabit Ethernet access ports with RJ45 interfaces; these ports also support 10/100Mbps connectivity. Two SFP+ interfaces provide for network uplink connectivity, and these ports support both Gigabit and 10 Gigabit pluggable transceivers. The 50-port models – ERS 4950GTS and ERS 4950GTSPWR+ – feature 48 1000BASE-T Gigabit Ethernet access ports with RJ45 interfaces; these ports also support 10/100Mbps connectivity.
