Fast EtherHub 3500 System User’s Guide Data Switching with the SmartExtender Modules Switching Technology The SmartExtender Modules that plug into the expansion slot on the front panel of the Fast Ethernet 3500 series use advanced switching techniques to provide a high-speed network backbone. Each extender module acts as a two-port Ethernet switch which effectively partitions the stack from the backbone.
Fast EtherHub 3500 System User’s Guide As a device functioning on the media access control (MAC) layer, the extender modules are protocol independent, and therefore compatible with IEEE802.3, IEEE802.3u, TCP/IP, NetWare, DECnet and XNS protocols. They can provide a connection between conventional 10BASE-T and high-speed 100BASE-TX networks; or can serve as a 2-port bridge in a 100BASE-TX or 100BASE-FX environment.
Fast EtherHub 3500 System User’s Guide flawless performance. To ensure that you can manage any kind of network load, the extender modules provide adaptive cutthrough switching based on Accton’s smart algorithm. This method dynamically changes the way it handles data based on the current error rate. This switching strategy start at fragmentfree for a clean to moderately dirty data environment, and changes to store-and-forward for a highly contentious environment.
Chapter 2: Installing the System This chapter describes how to install the Fast EtherHub unit and establish network connections. You may install this hub on any level surface (e.g., a table or shelf) or in a standard equipment rack. However, please take note of the following minimum site requirements before you begin.
Fast EtherHub 3500 System User’s Guide Hardware Installation F This hub is suitable for desktop or rack-mount installation. A good location is at the center of all the devices you want to link, close to a collapsed backbone, and near a power outlet. These hubs can be stacked with other hubs using a mounting rack or directly on top of one another. Refer to the sections on Stacking Hubs without a Rack or Mounting Hubs in a Rack for a description of these methods.
Fast EtherHub 3500 System User’s Guide Mounting Hubs in a Rack If you need to install a redundant power module, refer to Installing a Backup Power Supply on page 2-11, and complete that procedure before stacking the hub. Please comply with the following instructions to ensure that your hub is securely mounted in the rack. 1. Use an standard EIA 19-inch rack. 2. Use a Phillips (i.e., cross-head) screwdriver to attach the brackets to the sides of the hub. 3.
Fast EtherHub 3500 System User’s Guide Connecting the Hub System Remember to label all your connections at both ends of the cable to facilitate troubleshooting or future changes to network configuration. The Fast EtherHub has 12 RJ-45 shielded ports (i.e., 100BASE-TX) that support connections to 100 Mbps Fast Ethernet. Ports 1 - 12 (MDI-X) allow you to connect to devices such as a workstation, server or router. While Port 12 (MDI) lets you easily cascade to a compatible switch (i.e.
Fast EtherHub 3500 System User’s Guide 2. Connect one end of the cable to the RJ-45 port of the network interface card, and the other end to any available (MDI-X) station port on the hub. Just remember that if you use Port 12MDI-X, the daisy-chain port (12MDI) cannot be used. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. Using the hub in a stand-alone configuration, you can network up to 12 nodes.
Fast EtherHub 3500 System User’s Guide Making a Connection via the MDI Daisy-Chain Port The Fast EtherHub 3500 hubs are Class I repeaters. Class I repeaters cannot be cascaded to another repeater in the same collision domain. The daisy-chain port can only be cascaded to another device which breaks up the collision domain (e.g., an Ethernet switch).

When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. Note that as a general rule, the length of any twisted-pair cable should not exceed 100 meters.
Fast EtherHub 3500 System User’s Guide Note: To determine the power loss incurred by intervening devices and specific cable type, inquire with the manufacturer. The power budget depends on the gauge of cable as shown below. Gauge of Fiber Cable 50/125 mm 62.5/125 mm Power Budget 9.2 dB 13 dB Table 2.2 Power Budget for Common Guage Fiber Optics For a sample calculation, assume the following values: • cable gauge - 62.
Fast EtherHub 3500 System User’s Guide Setting the Communication Mode - The 100BASE-TX and 100BASE-FX SmartExtender Modules both support half and full-duplex communications. The hub uses auto-negotiation to determine the transmission mode for any new connection made to these modules. However, if a connected device does not also support auto-negotiation, and a link cannot be established using half duplex (i.e.
Fast EtherHub 3500 System User’s Guide SEM RJ-45 SEM SEG1 SEG2 RJ-45 SEG3 This stack has been fully interconnected using two extender modules. Interconnecting Stack Segments - Hubs can be completely isolated from the stack, or can be attached to any of the three available segments embedded in the backplane. When attached to a segment (i.e., common collision domian), the hub can communicate with all other devices attached to that segment.
Fast EtherHub 3500 System User’s Guide Powering on the Hub 1. Plug one end of the power cord into a power outlet, and the other end into the power socket at the rear of the hub (in that order for reasons of safety). Then plug in the backup power module if you purchased this option. For reliable backup, connect the backup power module to a separate AC circuit. 2. Check the LED indicator marked PWR1 (or PWR2) on the front panel to see if it is on.
Fast EtherHub 3500 System User’s Guide The following table shows the components to be tested.
Fast EtherHub 3500 System User’s Guide Configuring a Manageable Stack To manage the stack with the on-board configuration program or any optional network management software, the stack must include an EtherHub-12mi (i.e., a unit with an SNMP agent). Moreover, the network management station must be able to access the segment containing the management agent. You should also consider adding a backup SNMP agent to provide greater management reliability for critical applications.
Fast EtherHub 3500 System User’s Guide Verifying Port Status Check each connection by viewing the port status indicators listed below. (For a more detailed description on these indicators, refer to Chapter 5.) LED State Indication Link On Port has established a valid network connection.

Chapter 3: Setting up Network Connections Special Architecture Used for the Fast EtherHub 3500 Stack Multi-Segment Architecture The Fast EtherHub 3500 system supports multi-segment configuration through the FlexBus cabling. Three Ethernet segments (i.e., separate collision domains) are embedded in the hub’s FlexBus port (i.e., the stack’s backplane). You can choose to attach a hub to one of these segments, or to leave it isolated except for the management channel. Nodes attached to a specific segment (e.
Fast EtherHub 3500 System User’s Guide FlexBus 3500 Management Link The management link in a chain of cascaded hubs must be connected to manage the stack as a single unit. This means that only hubs connected using the FlexBus can be controlled by an SNMP management agent (i.e., Fast EtherHub-12mi). At most, 6 hubs can be managed and linked together using the FlexBus connection. Hub ID Setting In a stacked system, each hub should have a unique ID number to identify itself.
Fast EtherHub 3500 System User’s Guide Multiple Agents The on-board configuration program only provides access to the private MIB. To gain full SNMP functionality, you must use optional network management software (e.g., AccView/Open). You may include multiple agents in a stack. To provide a failsafe backup management agent, include it in the same segment with the Master agent. You may also use several active agents in the same stack.
Fast EtherHub 3500 System User’s Guide Port Backup Function The Fast EtherHub 3500 system supports a port backup function (i.e., a redundant link). A hub system can have up to 18 pairs of redundant links. These links are configurable using the in-band or out-of-band management program. When a primary link fails, the secondary (i.e., backup) link automatically takes over. Notes: 1. To prevent traffic from looping, the primary port is enabled and the backup port disabled.
Fast EtherHub 3500 System User’s Guide Sample Network Configurations The Fast EtherHub 3500 series stackable hubs are designed to provide flexibility in configuring network connections. This hub can be used as a simple stand-alone hub or connected to other network interconnection devices in various configurations. This section includes sample applications, most of which take advantage of the multi-segment architecture. Pay attention to the examples that illustrate how to segment a hub stack.
Fast EtherHub 3500 System User’s Guide Attaching the Stack to Multiple Segments This example shows 3 independent Ethernet LANs in a stacked system. Hubs 1 and 2 are attached to segment 1, while hubs 3 and 4 are attached to segment 2, and hubs 5 and 6 are attached to segment 3. This configuration serves to both balance the network load and improve performance. Using three separate segments provides 300 Mbps of Ethernet bandwidth to the overall stack.
Fast EtherHub 3500 System User’s Guide Isolating Specific Hub Connections You can interconnect or isolate the hubs in a stack using a multi-segment configuration. In a stacked system, some hubs may be connected to a segment while others are isolated (not attached to any segment). In this example, hubs 1 and 2 are attached to segment 1, while hubs 3 and 4 are attached to segment 2. However, hubs 5 and 6 are not connected to any segment. These hubs form isolated segments.
Fast EtherHub 3500 System User’s Guide Isolating Each Hub In this example, each hub in the stack is an independent segment (i.e., isolated collision domain). Hubs 2 to 6 are not connected to any of the 3 segments embedded in the FlexBus 3500 cable. ID 1 E the rH ub 350 0 A G E NT M AN AG E M E N T C H ANN E L E therH ub3500 HU B ID 2 S E G .

Fast EtherHub 3500 System User’s Guide Extending the Network with Alternate Connections You can extend your network by connecting any of the hubs in a stacked system to other compatible hubs via the SmartExtender Module. In the diagram below, a stand-alone hub is connected to hub 3 in the stacked system using the extender module. However, remember that the Fast EtherHub 3500 Agent can only manage hubs connected to it through the FlexBus connection.
Fast EtherHub 3500 System User’s Guide Linking the Stack to a Management Station In a stacked system, connect the in-band management workstation to the same segment that the management agent is attached to. In this example, the management agent is attached to segment 1. Thus, the in-band management workstation (e.g., a PC running AccView/Open) should also be connected to segment 1. SEGMENT 1 EtherHub 3500 AGENT MANAGEMENT CHANNEL EtherHub3500 HUB SEG. LINK 1 SEGMENT 1 SEG.
Fast EtherHub 3500 System User’s Guide Interconnecting the Segments The 3 segments within a stacked system can be combined into an interconnected network using the SmartExtender Modules. For example, you can connect all the segments in the stack using just two extender modules as shown below. Using this approach, you provide a higher bandwidth by using three separate collision domains, but still permit stations to communicate with nodes in other segments, as required.
Fast EtherHub 3500 System User’s Guide Connecting Remote Stacks Fast EtherHub stacks can be connected by using the SmartExtender Modules. For example, you can connect two stacks by running a cable from the extender module in one stack to any station port in a remote stack. When using twisted-pair cable, the maximum cable length is 100 meters. Also note that when you connect directly to a repeater bus in this manner, the transmission mode is limited to half duplex.
Fast EtherHub 3500 System User’s Guide Operating in the Novell NetWare IPX Environment If you’re using Novell NetWare server as your Network Operating System, you can have up to 3 LAN adapters installed in the File Server. With this type of setup, the network is perceived as logically divided into different collision domains, but the File Server is still accessible by all nodes.
Fast EtherHub 3500 System User’s Guide Operating in the TCP/IP Environment In TCP/IP Internet environment, gateways are used to improve performance and regulate network traffic by confining most network activity to their respective local network, and still maintain communication links among LANs of the same or different architectures. You can implement an IP subnet gateway if you have an IP network address (e.g., 140.20.0.0).
Fast EtherHub 3500 System User’s Guide Connecting to the Network Backbone The stack can be connected to the network backbone by attaching it to a device such as a Fast Ethernet switch. The following figure shows a direct connection from the stack’s daisy-chain port to a 100BASE-TX switch which is serving as collapsed network backbone.
