1 Installation ■ Installing the Module ■ Removing the Module ■ Clearing a Password Installing the Module The HP 100VG SNMP/Bridge Module is installed in the 100VG Expansion Slot on the back of an HP AdvanceStack 100VG Hub (100VG hubs are listed on page iii). Warning Before installing the HP 100VG SNMP/Bridge Module, unplug the HP AdvanceStack Hub from the power source. Electrical shock could result if you attempt to install the module without unplugging the hub.
Installation Installing the Module Installation 1. Unscrew the two captured screws holding the cover plate to the hub’s 100VG Expansion Slot and remove the cover. Note that the screws will release outward when unscrewed far enough. Do not unscrew them completely from the cover plate. Also notice that only modules with a “Compatible Modules Only” sticker on the component board are to be inserted into the hub. loosen these two screws Hub expansion slot 2.
Installation Installing the Module 5. Slide the handle to the closed position. 6. Turn on the power to the HP AdvanceStack hub by plugging in the power cord (there is no On/Off switch). If the HP 100VG SNMP/Bridge Module is installed and functioning correctly, the Expansion Slot (“Exp Slot”) LED on the front of the hub will be lit (solidly ON) after the self-tests have completed. The following illustration shows the location of the Exp Slot LED on the front of the HP J2415A AdvanceStack 100VG Hub-14.
Installation Installing the Module Installation For traffic received from the Ethernet/IEEE 802.3 LAN and intended for the 100VG LAN, Demand Priority Protocol is used for network access. The bridge acts as a standard 100VG LAN port by sending normal-priority requests to the hub for permission to transmit packets onto the 100VG LAN. For traffic received from the HP 100VG LAN and intended for the Ethernet/ IEEE802.
Installation Removing the Module Removing the Module Warning 1. Remove power from the hub by unplugging the power cord. 2. Unscrew the two captured screws holding the module. 3. Slide the handle (to the left) into the open position. 4. Pull the module out of the slot. 5. Replace the cover plate over the slot using the two screws that hold it in place. Be careful not to overtighten the screws. When using the hub, the cover plate must always be installed.
Installation Clearing a Password Installation Caution If the HP 100VG SNMP/Bridge Module is removed from the hub and inserted into another hub, the IP address and any other configuration information in the module’s firmware are lost. The HP 100VG SNMP/Bridge Module will reset itself to the factory defaults when the new hub is powered on. If you remove the HP 100VG SNMP/Bridge Module from a hub and then re-insert it into the same hub, however, no firmware configuration information is lost.
Installation Clearing a Password As an indication that the password has been cleared, the Security LED on the front of the hub will come on and stay on until the button is released. After the password has been cleared, access to the hub from software will no longer be password protected. A new password can be assigned from either HP Stack Manager, the ASCII console, or HP Interconnect Manager.
2 Graphical Software ■ Stack Manager Extended Features ■ HP Interconnect Manager Features When you install an HP 100VG SNMP/Bridge Module in your AdvanceStack 100VG Hub, the functionality from both out-of-band management (HP Stack Manager) and in-band management (from an SNMP network management station) is now available. Without the HP 100VG SNMP/Bridge Module installed, the hub cannot be directly managed in-band.
Graphical Software HP Stack Manager Extended Features A description of each extended feature follows on the pages below. For specific information about how to use a feature, consult the online help in HP Stack Manager. Module Bundle Connection Use this feature if you have purchased the HP Dial-A-LAN Bundle or the HP Router 210 Bundle to connect to the console for the respective daughter card.
Graphical Software HP Stack Manager Extended Features Factory Reset When you install an HP 100VG SNMP/Bridge Module in your hub, the Reset function offers an additional reset option, Factory Reset. Use this reset option to return the hub and the HP 100VG SNMP/Bridge Module to the original factory configuration. All configuration except the IP configuration is returned to the factory values.
Graphical Software From HP Interconnect Manager From HP Interconnect Manager The HP 100VG SNMP/Bridge Module has embedded SNMP agent code allowing an HP AdvanceStack 100VG Hub, with the module installed, to be managed by HP Interconnect Manager and any other SNMP-compliant network management product.
Graphical Software From HP Interconnect Manager IP Addressing:. By default, the hub with an HP 100VG SNMP/Bridge Module installed is configured to automatically seek an IP address from a BOOTP server on the network. This is done when the hub is powered on. If an IP address is not found, the Module will seek an IP address every ten minutes until it finds one.
3 ASCII Console ■ ASCII Console Features ■ Connecting to the ASCII Console ■ Using the ASCII Console When you install an HP 100VG SNMP/Bridge Module in your AdvanceStack 100VG Hub, you can use the ASCII console provided in the firmware of the SNMP/Bridge Module. This chapter describes the features available and how to make a connection to the ASCII console. ASCII Console Features The ASCII console has similar features to HP Stack Manager.
ASCII Console ASCII Console Features =>HE HElp [cmd] or ? [cmd] - displays this list of hub commands or detailed help for a specific command. ADdress - Sets address display mode in Ethernet (default at startup) or Token Ring. AUxiliary - connects to card attached to SNMP Module. BOx configuration - allows configuration of the box uplink ports. BRidge - configures bridging status & aging time. BUndling - configures the cable settings for the hub.
ASCII Console Connecting to the ASCII Console Connecting to the ASCII Console To use the ASCII console, you need to connect a terminal to the hub’s console port in the following ways: ■ directly, using a serial cable and a terminal (or a PC using a terminal emulator) ■ remotely, using a modem and a terminal ■ remotely, using Telnet (The directions to remotely connect with a modem and a terminal are described in your 100VG hub manual.) The HP AdvanceStack hubs support a single console session only.
ASCII Console Connecting to the ASCII Console Remotely, Using Telnet The HP AdvanceStack hubs support a Telnet console session. By default, Telnet is enabled. You can disable Telnet by using the IPconfig console command. To establish a Telnet session, follow these steps: 1. Verify the hub you are accessing has an HP 100VG SNMP/Bridge Module installed, that it has been configured with an IP address, and that it is accessible from your PC or workstation by using the ping command. 2.
ASCII Console Using the ASCII Console Using the ASCII Console The console session starts with a display similar to the following (the actual version numbers may be different): The first command entered is usually HE to list all available commands. All commands have online help that describes how to use them. If a password has not been assigned with the PAssword command, then you are not prompted for your password here.

4 Troubleshooting ■ Diagnosing the Problem ■ Customer Support Services The primary tools for troubleshooting the HP 100VG SNMP/Bridge Module are the LEDs on the front of the hub and the LEDs on the HP 100VG SNMP/Bridge Module. Use this troubleshooting table to diagnose the problem with your HP 100VG SNMP/Bridge Module.
Troubleshooting Customer Support Services Remember that if you install this module into the HP J2410A AdvanceStack Hub-15, the AUI/Xcvr Slot located on the front of the Hub-15 is no longer active. A cable connected to that port will not transfer data. That 10Base-T transceiver slot only works when the HP J2414A SNMP/Bridge Module is installed in the Hub-15. Use the transceiver slot on the module itself when the HP J2414B SNMP/Bridge Module is installed.

B Network Addressing ■ Communications Between Hub and Network Management Station ■ IPX Addressing for Novell NetWare ■ IP Addressing for IP and non-IP Networks ■ Using Bootp Communication Between the Hub and Network Management Station The HP AdvanceStack 100VG Hubs that have an HP 100VG SNMP/Bridge Module (HP J2414B or HP J2414A) installed in them can be managed over the network by HP network management products, for example HP Interconnect Manager.
Network Addressing IPX Addressing for Novell NetWare IPX Addressing for Novell NetWare Network Addressing 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 100VG Hub that has an HP SNMP/ Bridge module; the firmware becomes active when the management module gets an IPX address. The IPX address consists of a network number and a device identification.
Network Addressing IP Addresses for IP and Non-IP Networks IP Addresses for IP and Non-IP Networks If you have chosen to manage your hub with an SNMP/IP network manager, your management module in 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. Otherwise, you can build your own IP addressing scheme (described on the next page).
Network Addressing IP Addresses for IP and Non-IP Networks Building Your Own IP Addressing Scheme If your network is isolated and will not be connected to any other networks that use IP addressing, you can build your own IP addressing scheme (locally administered addresses). If you use your own addressing scheme, be aware that any connection to another IP network could cause communication problems on both networks. The IP addresses on the two networks must be compatible. Each address must be unique.
Network Addressing Using Bootp Using Bootp Bootp (Internet Boot Protocol) is used to download network configuration data from a server (the Bootp server) to the hub. The configuration data the hub retrieves from the Bootp server is: ■ the IP address for the hub ■ the subnet mask for the subnet on which the hub is installed ■ the default router The Bootp Process When the hub is powered on, it broadcasts Bootp requests that contain the hub’s station address.
Network Addressing Using Bootp Network Addressing Definitions of the table entry fields: 100vghub is a user-defined symbolic name to help you find the correct section of the bootptab file. 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. ht is the “hardware type” tag. For the HP AdvanceStack 100VG Hub-14, set this to ether (for Ethernet). This tag must precede the ha tag. ha is the “hardware address” tag.
