Note: When connecting hubs with the Stacking Cable, they are all part of the same collision domain by default. Also if a Hub-12TXM is present, all of the hubs are managed by it. 6. Isolate any hubs you want to remove from the stack’s collision domain. For the Hub-12TXM, use the Hub Configuration screen in the VT-100 console interface.
HP 100Base-T Hubs Installation and Reference Guide • Install the Switch Port Module on a non-isolated hub in the stack and run a connection from the Switch Port Module to a station port on the isolated hub. When connecting a hub to the 10/100TX Switch Port Module, the maximum cable length is 100 meters. This is a bridged connection and keeps the collision domain on the isolated hub separate from the main collision domain of the other hubs in the stack.
HP 100Base-T Hubs Installation and Reference Guide Special Considerations to Note The following are special considerations to note: • When connecting an end node to the Switch Port on the Switch Port Module, the maximum cable length is 100 meters for twisted-pair cable, and two kilometers for fiber. Refer to Chapter 2 for a more detailed description of the maximum cable length permitted.
HP 100Base-T Hubs Installation and Reference Guide • Make sure you connect the stack (main collision domain) to the extended network. If you have hubs in the stack that are isolated, be certain to use a station port of a hub that is NOT isolated in order to connect the stack collision domain to the extended network.

Chapter 1: Product Overview Introduction to Fast Ethernet Standard 10 Mbit/s Ethernet has served well for past generations of 286 and 386 machines performing simple file transfers. However, with the inevitable growth in corporate network size and the introduction of fully-functional 32-bit PC architectures, and operating systems running complex applications, 10 Mbit/s Ethernet has become a serious bottleneck.
HP 100Base-T Hubs Installation and Reference Guide addition, the entire installation can be monitored via SNMP protocol through any network management station. Moreover, the HP 100Base-T Hubs provide advanced network security features including “Intrusion Protection” which ensures that only designated workstations are able to transmit packets onto the network. Management access via the out-of-band serial port or in-band via Telnet is also password protected.

HP 100Base-T Hubs Installation and Reference Guide Data Switching with the Switch Port Modules Switching Technology The Switch Port Modules that plug into the Expansion Slot on the front panel of the AdvanceStack Hub-12TX/Hub-12TXM use advanced switching techniques to provide a high-speed network backbone. Each Switch Port Module acts as a two-port Ethernet switch that segments the stack from the extended network.
HP 100Base-T Hubs Installation and Reference Guide As a device functioning on the media access control (MAC) layer, the Switch Port Modules are protocol independent, and therefore compatible with 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 bridge in a 100Base-TX or 100Base-FX environment.
HP 100Base-T Hubs Installation and Reference Guide Although cut-though switching is recommended as the fastest method for most applications, the other methods mentioned above are also supported by the Switch Port Modules to guarantee flawless performance. To ensure that you can manage any kind of network load, the modules use adaptive cut-through switching based on an algorithm. This method dynamically changes the way it handles data based on the current error rate.
Chapter 2: Installing the System This chapter describes how to install the HP AdvanceStack 100Base-T Hubs 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. Note: The HP 100Base-T Hubs do not support wall mounting.
HP 100Base-T Hubs Installation and Reference 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 the extended network, 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.
HP 100Base-T Hubs Installation and Reference Guide Mounting Hubs in a Rack Please comply with the following instructions to ensure that your hub is securely mounted in the rack. 1. Use a 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. Position the hub in the rack by lining up the holes in the brackets with the appropriate holes on the rack, and then use the supplied screws to mount the hub in the rack. Figure 2.
HP 100Base-T Hubs Installation and Reference 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 HP 100Base-T Hubs have 12 or 24 RJ-45 shielded ports (i.e., 100Base-TX) that support connections to 100 Mbit/s Fast Ethernet. Ports 1 - 12/24 (MDI-X) allow you to connect to devices such as a workstation or server.
HP 100Base-T Hubs Installation and Reference Guide 100W Category 5 shielded or unshielded twisted-pair cables with RJ-45 plugs at both ends. 2. Connect one end of the cable to the RJ-45 port of the network device, and the other end to any available (MDI-X) port on the hub. Just remember that if you use Port 12MDI-X or Port 24MDI-X, the cascade port (12MDI/24MDI) 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.
HP 100Base-T Hubs Installation and Reference Guide Making a Connection via the MDI Cascade Port The HP 100Base-T Hub is a Class I repeater. Class I repeaters cannot be cascaded to another hub in the same collision domain. The cascade port can only be connected to another device which breaks up the collision domain (e.g., an Ethernet switch). Stackable Fast Ethernet hubs are generally restricted to Class I repeater types due to the timing requirements for passing traffic through the Stacking Cable.

I Retain the face plate for possible future use. The Switch Port Modules are not hot-swappable. Be sure you power off the hub before installing or removing these modules.
HP 100Base-T Hubs Installation and Reference Guide on the target device (or vice versa). 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 the length of twisted-pair cable should not exceed 100 meters. Connecting Fiber Optic Cabling - For the 100Base-FX module, prepare fiber optic cable with SC-type connectors at both ends. When connecting the module directly to an end-node device (e.g.
HP 100Base-T Hubs Installation and Reference Guide - When using fiber optic cabling, the maximum length between two hubs can be up to 2 kilometers. However, you must consider power loss when calculating the actual length of cable that can be used with your system. You can calculate power loss with the following formula: Distance Limit and Power Loss in Fiber Optics m = (p dB - i dB) c dB/km 9DULDEOH m p dB i dB c dB/km 'HVFULSWLRQ cable length (kilometers) power budget intervening devices (e.g.
HP 100Base-T Hubs Installation and Reference Guide I When the 100Base-FX link is set for the full-duplex communications (i.e., a dedicated connection), cable length should not exceed 2 kilometers. However, when the link is set for half-duplex communications (i.e., a shared collision domain), cable length should not exceed 412 meters (IEEE 802.3u). Also cable length could be limited further by timing constraints depending on what devices exist in the same shared collision domain. (See preceding section.
HP 100Base-T Hubs Installation and Reference Guide address is in the local collision domain, or forwarded if the destination is in a remote collision domain). Note: Devices connected to the Switch Port Module exist in a separate collision domain, and cannot be controlled by a management agent in the stack. Switching Functions - These modules also provide functions commonly found on an Ethernet switch. The scheme used to process data packets is automatically adjusted to optimize system performance.
HP 100Base-T Hubs Installation and Reference 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). 2. Check the LED indicator marked 3RZHU on the front panel to see if it is on. 3. The hub performs a self-diagnostic test upon power-on. (Note that this test takes about 50 seconds to complete.) For details about the system self-diagnostic test, refer to the following section.
HP 100Base-T Hubs Installation and Reference Guide Hot Swap The HP 100Base-T Hubs support a “hot swap” capability that allows you to connect/disconnect hubs or media connectors from the system with minimal disruption to the network. You can remove any network cabling without affecting traffic passing across the internal repeater bus.

Chapter 3: Setting up Network Connections This chapter outlines several sample configurations for a local area network utilizing specific features of an HP 100Base-T Hubs stack. As described in Chapter 2, up to five HP 100Base-T Hubs can be connected together using the Stacking Cable, which attaches to the Stacking Ports (on the rear panel), to create a complete hub stack. Hubs connected in this way form a single collision domain that extends across all hubs in the stack.
HP 100Base-T Hubs Installation and Reference Guide resources to balance traffic and thereby increase overall network efficiency. To combine the separate collision domains into an interconnected network, attach each hub to a switch or similar device, such as one of HP’s AdvanceStack switches, or use the optional Switch Port Modules. Stacking Cable Management Channel To manage other hubs by an SNMP agent (i.e.
HP 100Base-T Hubs Installation and Reference Guide Using Management Agents The Hub-12TXM includes an SNMP management agent. To add SNMP functionality to an entire stack, a Hub-12TXM must be included in the stack. You may include multiple agents in a stack to provide a fail-safe backup management agent. SNMP Backup Agent The HP 100Base-T Hubs system supports a backup function for the management agent.
HP 100Base-T Hubs Installation and Reference Guide Backup Links Function The HP 100Base-T Hubs system supports a backup link function (i.e., a redundant link), provided a Hub-12TXM is included in the stack. A hub system can have up to 10 pairs of Backup Links. These links are configurable using the VT-100 console interface. When a primary link fails, the backup (i.e., secondary) link automatically takes over.
HP 100Base-T Hubs Installation and Reference Guide Sample Network Configurations The HP 100Base-T Hubs are designed to provide flexibility in configuring network connections. This hub can be used as a simple standalone hub or connected to other network interconnection devices in various configurations. This section includes sample applications, most of which take advantage of the hub’s isolation technique, using the Switch Port Modules.
HP 100Base-T Hubs Installation and Reference Guide Isolating Specific Hub Connections You can connect or isolate the hubs in a stack. In a stacked system, some hubs may be connected to the stack collision domain while others are isolated. In this example, hubs 1, 2, 3 and 4 are in the stack while hub 5 is isolated from the stack. To isolate hubs from the stack use the Hub Configuration screen in the VT-100 console interface (see the Hub Configuration screen in the VT-100 console interface in Chapter 4).
HP 100Base-T Hubs Installation and Reference Guide Isolating Multiple Hubs In this example, each isolated hub has its own collision domain. Hubs 1 to 5 are not transmitting network traffic to other hubs through the Stacking Cable. Figure 3.
HP 100Base-T Hubs Installation and Reference 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 Switch Port Module. In the diagram below, a standalone hub is connected to hub 3 in the stacked system using the Switch Port Module. However, remember that the Hub-12TXM agent can only manage hubs connected to it through the Stacking Cable. Figure 3.
HP 100Base-T Hubs Installation and Reference Guide Linking the Stack to a Management Station In a stacked system, connect the management station to either a Hub-12TXM or to a hub that is not isolated from the stack. Note that to manage the main collision domain, the management station cannot be connected to a hub that is isolated from the stack collision domain because it must communicate with the management agent on the Hub-12TXM.
HP 100Base-T Hubs Installation and Reference Guide Interconnecting Isolated Collision Domains Isolated collision domains within a stacked system can be combined into an interconnected network using the Switch Port Modules. For example, you can connect all of the different collision domains in the stack using several Switch Port Modules as shown below. Each Switch Port Module serves as a bridge between isolated collision domains in the stack.
HP 100Base-T Hubs Installation and Reference Guide Connecting Remote Stacks Fiber optic cable provides an advantage for inter-stack connections because it can be connected over greater distances. This enables multiple stacks in remote locations to be connected. The HP 100Base-T Hubs stacks can be connected by using the fiber port on the 100FX Switch Port Module.
HP 100Base-T Hubs Installation and Reference Guide Connecting to the Extended Network The stack can be connected to the extended network by attaching the HP 100Base-T Hub to a device such as an HP AdvanceStack switch. The following figure shows a direct connection from a stacked hub’s MDI port to a 100Base-TX switch that is serving as a collapsed network backbone. Figure 3.
Chapter 4: Configuring the System Making the Connections Required for System Configuration The HP 100Base-T Hubs provide a menu-driven VT-100 console interface. This can be accessed by making a connection to the Console Port on the front of the hub (using a terminal or a computer running a terminal emulation program). Moreover, when configuring the Hub-12TXM, you can Telnet into the hub from any computer attached to the network, or call into the hub from a remote computer using a modem connection.
HP 100Base-T Hubs Installation and Reference Guide Direct Connection The Hub-12TX and Hub-24TX do not include a management agent. Configuration options for these models are therefore limited to direct connection only. Moreover, configuration via the Console Port on these models is limited to that hub only (i.e., the attached stack cannot be managed with these models).
HP 100Base-T Hubs Installation and Reference Guide Local Network Connection If you want to use HP AdvanceStack Assistant to discover the HP 100Base-T Hubs system, then first set up your Network Management Station (NMS). The NMS is the personal computer used to run your network management software. HP provides Windows and Unix-based network management through software called HP AdvanceStack Assistant. This Windows software comes with the hubs as part of the product offering.
HP 100Base-T Hubs Installation and Reference Guide Configuring the Remote Site At the remote site, connect the PC’s COM port (COM 1~4) to the modem’s serial port. Set terminal emulation type to VT-100, specify the port used by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, and 9600 bps. Also be sure you set the flow control to “none.
HP 100Base-T Hubs Installation and Reference Guide Configuring Your System You can configure the HP 100Base-T Hubs using the VT-100 console interface. On-board configuration requires a terminal or a computer running a terminal emulation program as your working platform. There are three valid connection types to the hub: • Out of band connection The workstation, normally within the vicinity of the hub, is directly connected to the Console Port on the HP 100Base-T Hub.
HP 100Base-T Hubs Installation and Reference Guide From a Telnet connection Telnet into the target hub using its assigned IP address. From a remote modem connection Use a VT-100 terminal emulation package to connect to the Com port that is attached to the modem. Configure the connection for 9600 baud, 8 data bits, no parity bits, and 1 stop bit. Then dial in to the hub. If the screen is blank, press the Enter key several times until the login screen appears.
HP 100Base-T Hubs Installation and Reference Guide Using the VT-100 Console Interface The Hub-12TX, Hub-12TXM and Hub-24TX all provide a menu-driven VT-100 console interface. The VT-100 console interface differs for the Hub-24TX, Hub-12TX and the Hub12TXM. The connection types allowed and options provided are summarized below: • The Hub-24TX is designed as a manageable hub, without an on-board SNMP agent. Therefore, when an SNMP agent (i.e.
