SwitchReady Fast Ethernet Stackable Hubs

Unmatched Scalability for Fast Ethernet Networks


    • Stackable up to Eight Units High to Form a 192-Port Multi-Media Hub
    • Segmentable up to 16 Fast Ethernet Segments per Stack
    • Scalable up to 1.60 Gbps of Aggregate Bandwidth
    • Manageable In-Band and Out-of-Band via SNMP and RMON
    • Integrated 10/100 Switching
    • Redundant Power Support

With its unique combination of scalable bandwidth, network management and integrated switching options, SMC's TigerStack™ 100 family creates a flexible and fault-tolerant environment for growing Fast Ethernet networks and for networks containing a mix of Ethernet and Fast Ethernet products.

The 12- and 24-port 100BASE-TX and -T4 hubs form the basic building blocks of this family. Fully compatible with IEEE 802.3 and 802.3u specifications, these hubs may be stacked in any combination. A slide-in module with one 100BASE-FX or 100BASE-TX port offers support for alternate media. And, a Redundant Power Unit (RPU) prevents network downtime in the event of a power supply failure.

The Network Management Unit (NMU) adds versatility by supporting a full range of unified management options. One expansion slot hosts an innovative RMON Probe Switching Module; and the other slot, a variety of 2- and 4-port Integrated Switching Modules so you can easily boost network bandwidth, connect to legacy LANs and support topology extensions without having to purchase a separate device.

Since the TigerStack 100 is SwitchReady™, "bandwidth-on-demand" can be achieved by isolating individual hubs or groups of 12 ports within the stack. Depending on connectivity or bandwidth requirements, these segments may be interconnected through a Fast Ethernet workgroup switch or integrated switch ports.

With SMC, you can be sure you're getting products of exceptional quality, reliability and value.

Integrating Ethernet and Fast Ethernet


    • Stackable Eight Units High
    • Expandable to 192 Ports
    • Slide-in Fiber and TX Modules
    • Redundant Power Supply
    • Temperature Sensor

Stackable and Expandable
With SMC's TigerStack 100 hubs, it's easy to introduce Fast Ethernet to an Ethernet LAN. The hubs can be used standalone for small groups of power users. And, as the network expands, as many as eight hubs can be stacked in any combination to form a single repeater with up to 192 ports. Since you can mix media types and port densities in the same stack, you can always buy what you need when you need it.

Flexible and Fault-Tolerant
There are TX hubs for certified Category 5 cable and T4* hubs for other twisted-pair cable types. And, front-panel LEDs to monitor bandwidth utilization, as well as both port and hub status.

In addition, one port on each hub can be replaced with a slide-in module for mixed media connectivity. With the FX module, you can add fiber to extend the reach of your network, and with the TX module, connect a T4 hub to a TX switch or station.

There's also a Redundant Power Unit (RPU) to minimize downtime in the event of an AC circuit loss or internal power supply failure. The RPU has its own power cord so it can provide power to up to five devices from a separate circuit breaker. And, there are front-panel LEDs to monitor the status of both the internal and external power supplies.

What's more, there are sensors to protect the electronics inside these devices. A warning LED will light if a hub overheats or a fault is detected in the RPU.

* SMC developed and patented the 100BASE-T4 signalling method, which uses three wire pairs to transmit and receive data, and a fourth wire pair to listen for collisions (SMC's U.S. Patent No. 5,544,323).

Integration of 10 Mbps and 100 Mbps LANs can be achieved economically by installing a 2-port Integrated Switching Module in the NMU.

To scale network performance, interconnect both technologies through a switch and give the server its own dedicated 200 Mbps bandwidth. The switch supports multiple conversations simultaneously, provides wire-speed throughput to all segments, and enables the server to focus on its primary tasks.

Increasing LAN Bandwidth


    • Segmentable to 16 Collision Domains
    • Scalable to 1.6 Gbps of Aggregate Bandwidth
    • Integrated Switching for Bandwidth Boost, Legacy LAN and Long Distance Connections

Highly Segmentable
When traffic on your mixed Ethernet/Fast Ethernet network increases, you can microsegment SMC's TigerStack and TigerStack 100 hubs and interconnect the isolated segments via switched ports. Microsegmentation reduces the number of nodes on a segment, minimizing contention and boosting the available bandwidth per node. Since a switch provides wire-speed throughput to each segment, a stack/switch combination can easily allocate and scale bandwidth to workgroups that need it.

With the TigerStack 100, entire hubs or groups of 12 ports can be isolated at the flip of a front-panel switch or via software to form as many as 16 separate segments. And, by adding a Segment Management Module (SMM) to each segmented hub, the entire stack can be managed by the Network Management Unit (NMU) via a single interface.

Easy Interconnections
Each TX segment has an uplink port so it can be connected to a switch with straight-through cable. For the T4 hubs, a TX module can provide connectivity to a switched TX port. And, by adding an FX module, both hub types can be connected to a switched fiber port.

Integrated Switching
With the TigerStack 100, you can increase the aggregate bandwidth of your network by adding an Integrated Switching Module to the NMU. Featuring a combination of Ethernet and Fast Ethernet ports, these low-priced modules can also be used for legacy LAN and long distance connections.

They're available in 2- and 4-port configurations, with one port reserved for connection to the stack's inter-repeater bus. The remaining 10/100 Mbps and 100BASE-FX switched port(s) may be set to operate in either half- or full-duplex mode. An FX port with up to 2 km of fiber cable can be used for connectivity to a backbone or higher speed technology. A 10/100 Mbps port provides connectivity to a 10 Mbps Ethernet LAN, server, or even to segments which have been isolated from the stack.

With an economical 4-port Integrated Switching Module in the NMU, the aggregate bandwidth of the network can be scaled to 500 Mbps - that's 100 Mbps for each of the three TigerStack 100 segments including the inter-repeater bus (IRB), and 200 Mbps for a server operating in full-duplex mode.

To improve performance on high-traffic networks, the aggregate bandwidth can be scaled to 1.6 Gbps by subdividing the stack into 16 segments and interconnecting them through a switch. As before, each server can be given its own dedicated 200 Mbps segment.

Managing the LAN


    • SNMP and RMON Manageable
      • In-band
      • Out-of-band
      • Remote
    • Plug-in RMON Probe Switching Module

Front-panel LEDs on all units provide "at-a-glance" management. But, for more comprehensive capabilities, you can add SMC's intelligent Network Management Unit (NMU).

This unit features an RMON subset (including Event, Alarm, Statistics and History groups) for pro-active management, as well as SNMP for simple monitoring and control. Security features are built in to detect intrusions. If a packet's source address does not match the address assigned to that port, the port is automatically partitioned.

With the NMU, the stack can also be managed in-band via Telnet (either Client or Server).

The NMU contains a dedicated in-band port for a Network Management Station (NMS). In addition to freeing up a port on one of the hubs, this port allows the stack to be managed continuously in the event of a failure. The NMU also contains an RS-232 console port for out-of-band management (locally and remotely) via a terminal or SNMP using SLIP.

For effective control, the entire TigerStack 100 can be managed with EliteView™ for Windows, SMC's low-priced, Windows-based SNMP manager. EliteView will also manage the TigerStack and all of SMC's other intelligent Ethernet and Token Ring products, as well as third-party devices. And, snap-in applications are available for the most popular network management platforms, such as Hewlett Packard's OpenView for UNIX.

RMON Probe Support
A second expansion port in the NMU hosts an innovative RMON Probe Switching (RPS) Module. With an SMM in each segmented hub and an RMON probe attached to the RPS Module, you can create a virtual connection to any TigerStack 100 segment. The module converts the probe to a roving multi-segment device, so all the segments can be probed without moving the probe connection.

With an external RMON probe, you can obtain an end-to-end view of network conversations and accurate host statistics, regardless of the network connection. A probe with RMON2 capabilities can map all the major network layer protocols, such as IP, IPX, VINES, DECnet, AppleTalk and OSI and provide an accurate enterprise-wide view of the network.

Front-panel LEDs provide "at-a-glance" management of the hubs by displaying the bandwidth utilization, link/activity and partition status, and temperature.

Add an NMU for in-band management via SNMP and RMON.

Add an RMON Probe Switching Module to the NMU and Segment Management Modules in each hub for roving, multi-segment SNMP and RMON.
