Managed Layer 3 Switch with 2 x 10G Uplink slots
OVERVIEW
SMC Networks’ TigerStack™ II 10/100/1000 SMC8926EM/SMC8950EM Switches are a new enhanced series
of high performance stackable switches that deliver high scalability, wire-speed Gigabit performance, high
availability, 10 Gigabit Ethernet uplinks, and redundant power options. These switches were the first to include both IPv4 and IPv6 Management options enabling future proofed flexibility and maintainability.
The TigerStack II 10/100/1000 SMC8926EM/SMC8950EM stacks up to 4 units in a stack, providing up to 192
Gigabit ports. A stack can be created with either 24 or 48 port switches, providing unprecedented flexibility.
It provides 48 built-in copper Gigabit ports, including (4) Combo SFP ports supporting either copper links
or SFP adapters for easy, flexible connection to fiber-based Gigabit media and a switching capacity of up to
186Gbps. The 2 10G module slots on the rear of the switch provide support for XFP 10G connections. These
provide high bandwidth connections to the core of a network and are in addition to the 2 stacking connectors
giving high capacity connections to the other units in the stack.
The SMC8926EM/SMC8950EM is the latest example of SMC’s continued commitment to our channel partners and customers to be the industry leader in cost-effective, reliable, high performance, feature-rich
KEY FEATURES
Layer 3 Routing Support Flexible Security Features
Advanced edge networks can have the requirement for layer 3
routing and this family of switches is able to offer that support in
hardware without additional cost.
switches.
Security is critical for advanced edge networks. This switch family
includes a range of User and Device security functions which will
help protect the network. Secure management interfaces for protecting device configuration and secure user access using 802.1x
or Private Vlans to prevent unauthorized access.
SWITCHES VDSL WIRELESS VOIP STORAGE BROADBAND ADAPTERS
Performance and Redundancy Quality of Service
Advanced edge networks are demanding higher performance and
reduced down time. SMC is committed to both of these requirements. Stacking switches together in a single wiring closest increases the uplink flexibility in terms of 10G uplinks and redundancy
in the event of a device problem. Similarly this switch includes a
Redundant Power option to protect against primary power failure.
Networks are supporting many different types of data including voice, video, email, file transfers. Each data type has different characteristics and requirements. The SMC TigerSwitch II
switches provide 8 levels of priority in hardware and flexible software to configure the system to address your specific network
requirements.
