OmniStack 6100 Series
Stackable Workgroup Switches
for the Enterprise

The OmniStack 6100 series, consisting of the OmniStack 6124 and 6148, are cost-
effective, stackable workgroup switches for building economical enterprise networks.
The OmniStack 6100s are designed for wiring closet and edge applications, and
deliver a great set of features including wirespeed performance, L2+ QoS capabilities,
port aggregation, security, IP multicast, and a scalable architecture utilizing dedicated
hardware based stacking. The OmniStack 6100s provide support for a wide variety
of uplinks for flexibility in supporting today’s enterprise applications.
The OmniStack 6100 series is a part of the Alcatel OmniStack family and consists of two stackable switching products: the
OmniStack 6124 (24-port) and the 6148 (48-port). These switches provide 10/100 Ethernet switching for workgroups and
are ideal for medium and large enterprise networks. The OmniStack 6100s protect existing investments because they
interoperate with all existing Ethernet and Fast Ethernet equipment and cabling, allowing workgroup networks to be easily
upgraded and enhanced with minimum disruption to operations.
Backbone connectivity – The OmniStack 6124 and 6148 connect to the core of the network via Fast Ethernet or Gigabit
Ethernet uplinks. With 802.3ad port aggregation, the uplink’s bandwidth can be increased in increments of up to four Gbps
without disruption.
The OmniStack 6124 and 6148 also support 10/100/1000BaseT, 1000BaseSX, 1000BaseLX, and1000BaseLH Gigabit
Ethernet ports to connect to a gigabit core switch. The long haul interfaces (1000BaseLX and 1000BaseLH) are used on
large campuses to link distant buildings. The short haul interfaces (1000BaseSX) are used as vertical connections within a
building.
OmniStack 6100 layer-2 switching at the edge can be combined with other Alcatel products including the OmniSwitch
7000 or 8000 in the core with its layer 2/3/4 classification – simplifying network complexity and minimizing overall
network costs.

Intelligent Performance
Whether you need to differentiate services for data applications or implement VoIP, your network infrastructure must be ready
to prioritize real time traffic. Even as layer 2 switches, the OmniStack 6100 supports traffic allocation to CoS-based on
802.1p and DSCP. This allows easy implementation and easy to manage end-to-end QoS throughout the network.
Adaptive networking
As enterprises grow or migrate to converged data and voice networks, network infrastructures must scale to support upgrade
requirements. When the number of users increases, the OmniStack 6100 can be extended to facilitate a smooth upgrade
path by simply adding units and high speed stacking links. 10/100 ports can also be aggregated to create a high-speed link
to a server or network backbone. Up to four full duplex 10/100 ports can be aggregated gradually to create an 800 Mbps
pipe. A distributed switching fabric guarantees enough power for wire-speed switching.
The OmniStack 6124 and OmniStack 6148 are interoperable and can be mixed in a single stack, thereby protecting the
existing investment in Alcatel switching products. This interoperability allows gradual migration to an advanced OmniStack
6100 stackable configuration with the benefits of flexibility and the ability to adapt to changes in network environments.
Simplified management
Simplifying network management can decrease the cost of ownership. Using industry standard SNMP traps and RMON
probes, the OmniStack 6100 provides enhanced management and easy configuration through a Web-based management
interface. Management is optimized via the Alcatel converged network management platform, OmniVista 2000, which is
compatible with leading products like HP OpenView and Computer Associates Network IT.
