    Network Management Station The HP AdvanceStack 10Base-T Hubs that have an HP Ethernet SNMP Module (HP J2603A or B) installed in them can be managed over the network by HP network management products, for example HP Interconnect Manager. These hubs can also be managed by any other...

  • Page 103: Ipx Addressing For Novell Netware

    The Novell NetWare network operating system uses a proprietary protocol called Internetwork Packet Exchange (IPX). The IPX protocol firmware is always available on an HP AdvanceStack 10Base-T Hub; it becomes active when the hub gets an IPX address. The IPX address consists of a network number and a device identification.

  • Page 104: Ip Addresses For Ip And Non-Ip Networks

    Network Addressing IP Addresses for IP and Non-IP Networks If you have chosen to manage your hub with an SNMP/IP network manager, your hub must be configured with an IP address. If your network will be connected with other networks that use IP addresses, you must use assigned IP addresses.
  • Page 105 Do not use 0 or 255 as the value in the last position on the right. They are reserved integers. For three hubs and an HP network management station on the network, the class C addresses might be: management station 192.1.1.1...

  • Page 106: Using Bootp

    If you have configured the hub’s IP parameters on a BOOTP server, you do not need to use the IP Configuration function in HP Stack Manager. As shipped from the factory, the hub is configured to use BOOTP to retrieve the IP configuration information.
  • Page 107 If you have multiple hubs that will be using BOOTP to get their IP configuration, you should use a unique symbolic name for each hub. is the “hardware type” tag. For the HP AdvanceStack 10Base-T hubs, set this to ether (for Ethernet). This tag must precede the ha tag .

  • Page 110 Description N o t e The Backup Link function is available only for HP AdvanceStack 10Base-T Hubs in which an HP Ethernet SNMP Module (HP J2603A or B) is installed. In some network configurations a critical link exists, for example between two workgroups that regularly share or exchange data over the network.

  • Page 111: Limitations

    Limitations The hubs at both ends of the redundant link must have an HP Ethernet SNMP Module installed. Each hub can monitor a single backup link (only one backup link can be configured on each hub). But, the hub may be at the remote end of one backup link and at the monitoring end of a backup link to a different hub.

  • Page 112: Configuring A Backup Link

    It is best to follow these steps: 1. Attach a PC running HP Stack Manager to the hub’s RS-232 port, or to the RS-232 port of any of the hubs in the chain containing the hub you want to configure, and start HP Stack Manager.

  • Page 113: Identifying The Backup Link

    (For instructions, see “Port Connections” in chapter 1, “Installing the HP AdvanceStack 10Base-T Hubs”.) 5. Enable the primary port with the HP Stack Manager’s Port function. This step is necessary because until you have completed step 3 (connecting the cables), the test packets cannot be successfully sent through the primary port.

  • Page 114: Indications Of Backup Link Activation

    On the hub’s LEDs, the primary port LED goes off, and the backup port LED goes on. On the HP Stack Manager’s front panel display for the hub, the status of the primary port changes from ON to OFF, and the backup port changes from OFF to ON.

  • Page 115: Reactivating The Primary Link

    When the primary link is repaired, you can use any of the following methods to re-enable the primary port: From HP Stack Manager click on the primary port on the Port Status display and use the Port function to enable that port.

  • Page 116: Example Topologies

    Example 1: Hub-to-Hub In this example topology, the primary and backup links consist of twisted-pair cable segments between two HP AdvanceStack hubs. Wiring Closet 1 Wiring Closet 2...

  • Page 117: Example 2: Backup Link Using Alternative Medium

    Medium In this topology, the primary link consists of a twisted-pair cable between twisted-pair ports on two HP AdvanceStack hubs; the backup link is from AUI port to AUI port on the two hubs. Depending on the type of transceivers used, the backup link could use thin coax, fiber-optic cable, or even twisted-pair cable.
