Installing the HP AdvanceStack Hub Installing the HP AdvanceStack Hub 4. Complete the Hub Network Connections Reconnect the hub to the power source and then make the network connections to the hub. Making network connections consists of the following procedures: connecting to network end nodes, such as personal computers connecting to another 100VG hub (“cascading”) connecting to a Ethernet/IEEE 802.
Installing the HP AdvanceStack Hub A 100VG LAN complies with the IEEE 802.12 standard and supports category 3, 4, and 5 four-pair, 100 ohm UTP (unshielded twisted-pair) cables. Category 3 UTP cable is standard, voice-grade, telephone cable. For more detailed information on supported LAN cables, refer to the included 100VG AnyLAN Technology Guide and appendix A. If you presently have a twisted-pair cable network that complies with Ethernet/IEEE 802.
Installing the HP AdvanceStack Hub Installing the HP AdvanceStack Hub Using Unbundled (4-pair only) Cables You can used unbundled cables to connect to devices that operate in either private mode or promiscuous mode. A private mode device (such as a typical end node) receives only those packets intended for it. A promiscuous mode device (such as a LAN analyzer or cascaded hub) receives all packets. A hub port that detects a promiscuous device assumes that an unbundled cable is being used.
Installing the HP AdvanceStack Hub To add additional 100VG network ports, HP AdvanceStack 100VG hubs can be “cascaded” together. To cascade HP 100VG hubs, connect a LAN downlink port on the upper-level hub to the “Uplink A” port on the lower-level hub. You can either use one cable or you can add a second cable to act as a redundant link. For a one or two cable setup, follow these rules: The type of cable you select depends on the optional transceiver you install in the upper-level hub.
Installing the HP AdvanceStack Hub Installing the HP AdvanceStack Hub Cascading Hubs using Redundancy You can building redundancy into your cascading hubs by connecting a second cable from the lower-level hub to the upper-level hub. The following illustration shows how to add the second cable: Upper-Level Hub Unbundled 4-Pair LAN Cable Lower-Level Hub Follow these steps to set up a redundant connection: 1. Connect the second cable following the bundling and cabling specifications on the previous page.
Installing the HP AdvanceStack Hub A Hub-14 can be connected to an Ethernet or IEEE 802.3 10 Mbit/s network. To connect to an Ethernet/IEEE 802.3 LAN, the hub must contain the following accessory products: HP J2414B 100VG/ET SNMP/Bridge Module installed in the 100VG Expansion Slot in the back of the hub, and One of the following Ethernet/IEEE 802.
Installing the HP AdvanceStack Hub Installing the HP AdvanceStack Hub Managing the Hub Cables The HP AdvanceStack hubs have been designed to help you manage your network cables. On the right side of each hub is a built-in cable management bar. cable management bar The bars have slots in them that you can use for tie-wrapping the network cables.
Installing the HP AdvanceStack Hub HP AdvanceStack 100VG hubs can be configured and managed through an out-of-band connection to a Windows-based PC that is running HP Stack Manager software. The HP Stack Manager software is supplied with each hub and is described in chapter 2, “Installing and Using HP Stack Manager”.
Installing the HP AdvanceStack Hub Installing the HP AdvanceStack Hub Using a Direct Serial Connection Each hub contains a 9-pin serial (RS-232-C) port that is used to connect the management console PC. When connected, the PC (running HP Stack Manager) can access the hub directly, or can access other hubs through the Distributed Management Chain. The “chained” connections are independent of any network connections between hubs. To connect a PC directly to the RS-232 port, proceed as follows: 1.
Installing the HP AdvanceStack Hub You will need two modems, one connected to the hub (the “remote” modem) and the other to the PC (the “local” modem). Full modem support requires an HP J2414B 100VG/ET SNMP/Bridge Module installed in the hub. The modems that have been tested for use with the HP AdvanceStack hubs are listed in the modem configuration screens in HP Stack Manager.
Installing the HP AdvanceStack Hub Installing the HP AdvanceStack Hub After you have connected the hardware together, you need to set up HP Stack Manager. The basic steps to connect the hub to HP Stack Manager with a modem link are: 1. Connect the “remote” modem that will be used on the hub to your PC’s serial port. 2. Configure the “remote” modem by using the Remote Modem initialization screen from the Settings menu in HP Stack Manager.
Installing the HP AdvanceStack Hub In some installations, the management console PC may access the hub through a data switching device (such as a Data Switch, Data Terminal, PBX switch, or X.25 PAD). The hub will be connected directly to one port of the data switch, while the management console may be connected directly or through a modem link to another port of the data switch.

HP Stack Manager The communications settings can be stored in an individual file for each serial connection. See the HP Stack Manager online help for more information.
Installing and Using HP Stack Manager Automatic Chain Display Once the connection is established between HP Stack Manager and the hub, information about the hub is displayed in the Device Chain List on the main screen. If the hub is connected to a Distributed Management Chain, the Device Chain List shows all detected hubs on the chain. The information displayed for each detected hub includes the hub model and its MAC address.
Installing and Using HP Stack Manager LAN Traffic Statistics The Hub Panel Graphic provides two bar graphs that indicate current network activity of the hub: The LAN Activity % graph identifies the proportion of total LAN bandwidth seen by the hub within a sampling time interval. The High Priority % graph indicates the proportion of hub LAN packets that are high priority packets within a sampling time interval.
Installing and Using HP Stack Manager If you select an Uplink connection and then click on Port Settings, several options are added to the Port Settings dialog. Ignore these options unless you are interested in using the second uplink connection in a redundant uplink configuration (described on page 2-7). With a second cable connected you can choose which connection is the active uplink port. By default, Uplink A is the active port.
Installing and Using HP Stack Manager Device Configuration Allows you to specify three selections: whether cabling is bundled (default is “some bundled”). If any ports on the hub are connected to a 25-pair bundle, ensure that the hub port cabling is set to “some bundled”.
Installing and Using HP Stack Manager Definition Readable frames received The count of valid frames received by the port. A valid frame is defined as a data frame which is not counted by any of the error counters. Readable octets received The count, in octets, of valid frames received by the port.
Installing and Using HP Stack Manager Security Features The Hub-14 has built-in per-port security. After you have set up security by clicking on the Security icon, security violations are reported in the Intruder Log. You can specify three levels of security on a single port or all ports on the hub. You can set the hub to learn a port’s authorized MAC address automatically by either continuous learning or acquiring the first address heard. Alternatively, you can assign an address directly.
Installing and Using HP Stack Manager Interoperability with Pre-Standard IEEE 802.12 100VG Devices The IEEE 802.12 standard specifies that null address training should not be successful. To be interoperable with pre-standard devices which may depend on null address training, HP Stack Manager, HP Interconnect Manager, and the ASCII console have added an option. In HP Stack Manager’s Port Security Configuration dialog box, the option is called “Prevent Training with Null Address”.
Installing and Using HP Stack Manager Send Alarm Any port may be configured to send an alarm (trap notification) to the network management station when an unauthorized MAC address or training capabilities violation is detected on the secured port. The functionality of the Send Alarm feature depends on whether you have an HP 100VG SNMP/Bridge Module installed in any 100VG hub in your management chain.
Installing and Using HP Stack Manager Hub Reset You can reset the hub through the Hub Reset dialog box. The Hub Reset dialog box is displayed when you click on the Hub Reset icon in the toolbar of the hub panel graphic.

Installing and Using HP Stack Manager Automatic ability to communicate with other devices on a Novell Netware (IPX) network. Password protection for access to the hub through the RS-232 console port or SNMP-based network management stations. HP EASE (Embedded Advanced Sampling Environment) for trend analysis of your network. (To use EASE, you need to buy the optional EASE software.) Full modem support.
3 LED Error Indications Troubleshooting Checklist Unusual Network Problems End to End Network Tests Diagnostic Tests Troubleshooting
Troubleshooting LED Error Indications Most problems with the hub can be diagnosed using the LEDs. Troubleshooting LED patterns indicating problems Diagnostic Tips Power Fault OFF * * * * Check power cord and power source connections. If connections are secure, then try a different outlet or try a different hub to see if the power cord is the problem. ON ON ON or OFF, not Flashing * * Disconnect power and reconnect power. If the Fault light is still on, the hub failed self-test.
Troubleshooting LED patterns indicating problems Power Fault LAN Ports ON * OFF or Flashing for a port in use * * Flashing Rapidly ON * Diagnostic Tips Security Module LEDs * Link training has failed on the indicated port most likely because of a faulty or improperly wired cable. Check cabling on the indicated port. Check the port status in HP Stack Manager to determine whether link training failed due to a cabling or a capabilities configuration error.
Troubleshooting Troubleshooting Checklist Most problem are caused by the following errors: Incorrect installation. Incorrectly installing the hub (including any optional modules) can result in improper operation. If one or all of these components appear to not be functioning, re-check the installation procedure in chapter 1 and, if necessary, re-install the component correctly. Wrong type of cable. Use only Category 3, 4, or 5 four-pair, unshielded twisted-pair cable rated at 100 ohms.
Troubleshooting Verify LAN link communications. Use HP Stack Manager’s software to check the Link Training status for each LAN port. These tests are available only on hubs that have an HP 100VG SNMP/Bridge Module installed. To test the hub’s ports and the attached network links, choose one of the following ways to run a test between the hub and an addressable device connected at the remote end of each of the cables you wish to test: Select Link Test from HP Stack Manager’s Network Test dialog box.
Troubleshooting Unusual Network Activity Network activity that exceeds accepted norms may indicate a hub or network problem. Most of the time, the unusual network activity can be removed by making sure that your network cabling and network topology adhere to the standards and requirements described in the HP 100VG AnyLAN Technology Guide. Troubleshooting Use HP Stack Manager to view the status of the LAN ports and to retrieve counter values.
Troubleshooting End-to-End Network Tests If your PC LAN adapters (or end nodes) support network communication tests, you can perform these tests through the HP 100VG hub to help isolate network problems. Refer to your LAN adapter documentation for more information on available network communication tests. Communication tests through the hub can be performed between two 100VG LAN end nodes equipped with 100VG LAN adapters.

The corresponding port is flashing at the same time for the port violation. Otherwise an SNMP intrusion has occurred on the SNMP/Bridge module. This intrusion may have occurred before the last hub reset. This LED will persist until it is cleared in software. This hub is not receiving power from the HP J2962A Redundant Power Supply (RPS).
Hub Reference Reset Button The Reset button resets the hub and performs the power-on self-test. It is recessed to prevent accidental resets. For a description of the effect of this reset, see page 2-15. Distributed Management Chain Extension Ports The Extension ports are used for chaining multiple hubs together on a special bus called the Distributed Management Chain. This chain is independent of any LAN connections, and allows you to manage multiple hubs from a single management station.
Hub Reference RJ-45 100VG LAN Ports The Hub-14 has 12 twisted-pair LAN ports to connect network devices, such as end node PCs, servers or other hubs. The LAN ports consist of built-in (8-pin) jacks for use with twisted-pair cables. Each LAN port requires four twisted-pair wires (8 wires total). Each LAN cable can be unbundled or bundled as described on page 1-16.
Hub Reference The Uplink port is a special promiscuous LAN port. As a promiscuous port, it sends and receives all packets to and from the upper-level hub. It is a special port because it can transmit multiple packets to the upper-level hub (for example, to accommodate the multiple end nodes that may be connected to the lower-level hub). Note The Uplink port can only be used to connect to an upper-level hub or switch and requires an unbundled LAN cable.
Hub Reference Back of the Hub 100VG Expansion Slot The 100VG Expansion Slot is used to add any of the following modules: HP J2414B 100VG/ET SNMP/Bridge Module HP J3157A AdvanceStack 100VG Dial-A-LAN 2A/Plus Bundle HP J3158A AdvanceStack 100VG Dial-A-LAN 4A Bundle HP J3159A AdvanceStack 100VG Router 210 Bundle For more information on these module, refer to the “Optional Modules” section of this chapter.
Hub Reference Cascading Hubs The Hub-14 has 12 downlink ports, any of which can be used to cascade to a lower-level hub. Lower-level hubs contain uplink ports that must be used to cascade up to an upper-level hub. In a network of cascaded hubs, the uppermost hub (whose Uplink port is not used) is referred to as the level 1, or “root”, hub. Note Although you should minimize the levels of cascading, up to five levels of cascaded hubs are supported. Three levels of cascaded hubs are recommended.
Hub Reference Chained Hub Operation HP AdvanceStack hubs (both 100VG and 10Base-T hubs) can be connected together with standard unshielded twisted-pair cable through their Extension ports (RJ-45) creating a Distributed Management Chain. The chain can support up to 16 hubs and can extend up to 185 meters (end-to-end) so multiple wiring closets can be managed from a single location (for example, a single PC running HP Stack Manager).
Hub Reference Serial Port Communications The RS-232 serial port is used by a management console PC to communicate with the hub, or to other hubs connected on a Distributed Management Chain. For information on serial port configuration, refer to chapter 2, “Installing and Using HP Stack Manager”, and to the online help system of HP Stack Manager. Note the following: The port supports multiple baud rates: 300, 1200, 2400, and 9600 (default) baud.
Hub Reference Security Features For ports operating in private mode, the hub provides inherent network data security. A private mode port will only receive packets intended for the attached device. In cascade mode, only private end-nodes or cascaded repeaters (hubs) are permitted to pass training. This mode should be used to permit promiscuous access for just other hub connections while keeping other connections private. An any device mode allows all devices including promiscuous ones, to train.
Hub Reference Optional Modules The following modules are described in this section: HP 100VG SNMP/Bridge Module HP Dial-A-LAN Bundles HP Router 210 Bundle Other modules may be available. Contact your HP-authorized dealer for more information. HP 100VG/ET SNMP/Bridge Module The HP 100VG/ET SNMP/Bridge Module (HP J2414B) is an optional component that can be added to an HP AdvanceStack 100VG hub to provide the hub with a full 10:100 and 100:10 bridge capability.

It also includes minimum pin-out information so, if you wish to use an unlisted cable, you can verify that the cables used in your installation are correctly wired. Note that each pin-out does not necessarily match the pin-out for the corresponding HP cable, but cables manufactured to follow the minimum pin-out will function correctly.
Cables and Connectors Cables and Connectors Recommended Cables Cable Function Port Type on PC, or Modem Cable Type HP Product Number Connecting devices and networks to the hub: Connecting twisted-pair LAN ports — Unshielded twisted-pair cable 92268A, B, C, D, or N (4-pair) Connecting an Ethernet/IEEE 802.3 LAN to ThinLAN transceiver module — IEEE Type 10Base2 Thin coaxial cable 92214U (0.5 meter), includes a BNC “T” connector and one 50-ohm terminator Connecting an Ethernet/IEEE 802.
Cables and Connectors Cables and Connectors Twisted-Pair Cable/Connector Pin-Outs Twisted-Pair Cable for 100VG LAN Ports To connect PCs and other devices to the 100VG LAN ports, use a “straight-through” 4-pair twisted-pair cable. The twisted-pair wires must be twisted through the entire length of the cable.
Cables and Connectors To chain hubs together on a Distributed Management Chain, use a “straight-through” twisted-pair LAN cable. The twisted-pair wires must be twisted through the entire length of the cable. The wiring sequence must conform to AT&T 258A (not USOC). See “Twisted-Pair Cable Pin Assignments” later in this chapter for a listing of the signals used on each pin. Straight-through cable blue/white white/blue Note Pins 4 and 5 must be wired to a twisted pair.
Cables and Connectors Cables and Connectors RS-232 Console Port Connector and Cable Pin-Outs The hub’s console connector is wired as if it is a terminal (DTE), ready to be connected to a modem (DCE). The HP AdvanceStack hubs include a null modem cable that can be used to directly connect a PC to be used as the console. To connect a modem to the hub, use a standard RS-232-C modem cable. This section provides pin assignment information for the cables you can use on the hub’s RS-232 management console port.
