At A Glance HP AdvanceStack 100VG Hub-7E At A Glance The HP J3137A AdvanceStack 100VG Hub-7E is a high-speed multiport repeater. With this hub, you can connect computers and other devices together in an unshielded twisted-pair cable network. This hub can be used to upgrade your 10 Mbit/s Ethernet/IEEE 802.3 network that uses unshielded twisted-pair cables to a 100 Mbit/s network. Throughout this manual, this hub will be called the Hub-7E. The following illustration shows the Hub-7E.
Installation Summary Installation Summary The basic hardware installation procedure for the Hub-7E is as follows: 1. 2. 3. 4. Verify included parts Verify that the hub works Mount the hub Complete network connections to the hub 1.
2. Verify that the Hub Works 2. Verify that the Hub Works Your hub uses power from an external DC power supply. To provide power to the hub, follow these steps: 1. Plug the DC power supply into the hub’s Power connector. Note If your installation requires a different power cord than the one supplied with the hub, contact your HP-authorized LAN dealer or your local HP sales office. 2. Plug the power cord into the power supply. 3. Plug the power cord into an AC power source.
3. Mount the Hub 4. Check the LEDs on the hub’s front panel. When the hub is powered on, it performs a self-diagnostic test. During the test, watch the LEDs on the front of the hub for the following to occur: At Power On All LEDs turn on. During Self-Test Self-test requires about 3 seconds. While the hub is tested, half of the LEDs are momentarily turned on and off. Then the remaining LEDs are momentarily turned on and off.
3. Mount the Hub Do not install the HP AdvanceStack hub in an environment where the operating ambient temperature might exceed 55°C (131°F). Make sure the air flow around the sides of the hub is not restricted. Mounting the Hub Important A hub should be mounted only to a wall or wood surface that is at least 1/2-inch (12.7 mm) plywood or its equivalent. The following illustration shows you how to mount the Hub-7E under a table.
4. Complete Network Connections to the Hub Installing the Hub 4. Complete Network Connections to the Hub Reconnect the hub to the power source and then make the network connections to the hub. With the hub mounted, you are now ready to connect the hub to your network. Typical hub connections are: Hub-to-device connections. Connecting to network devices such as computers and printers. Hub-to-hub connections. Connecting to another HP AdvanceStack 100VG Hub.
4. Complete Network Connections to the Hub Connecting Additional Hubs (“Cascading”) To add additional 100VG network ports, HP AdvanceStack 100VG hubs can be “cascaded” together. To cascade HP 100VG hubs, connect a LAN downlink port (ports 1 through 6) on the upper-level hub to the “Uplink” port on the lower-level hub. For a twisted-pair connection, use a standard four-pair unbundled LAN port cable.
Troubleshooting Troubleshooting Most problem are caused by the following errors: Incorrect position of the Frame Type switch. The Hub-7E is Token Ring ready. The Hub-7E operates with 100VG LAN adapters with 100VG Token Ring drivers running Token Ring frames. If you do not have these drivers, keep the Frame Type switch in the Ethernet position. Also note that the HP J2410A AdvanceStack 100VG Hub-15 does not support Token Ring and cannot be connected to the Hub-7E in Token Ring mode. Wrong type of cable.
Troubleshooting Troubleshooting with the LEDs If you have followed the above criteria, use the LEDs to troubleshoot your hub: LED patterns indicating problems Power Activity Cascade OFF * * Diagnostic Tips Fault LAN Port Port Uplink Port * * * Verify that the AC power cord is plugged into an active power source and to the hub. Make sure these connections are snug. Try power cycling the hub by unplugging and plugging the hub back in.
Troubleshooting Diagnosing the Hub through the ASCII Console The ASCII console provides tests and indicators that can be used to monitor the hub and its network connections. For more details about these tests and indicators. Each hub contains a 9-pin serial (RS-232-C) port that is used to connect the PC. The hub can be controlled from a PC running an ASCII terminal such as the Windows Terminal program.
Troubleshooting 3. Set the baud rate of your modem to 9600 or 19,200 bps. Press [Return] several times at your terminal emulator program. The following screen appears: 100VG 7 port hub ROM Version A.01.00 HELP RESET RESET n STATUS - Show this message. - Reset the hub. - Reset port n. (n = 1-6, UPLINK, ALL, or COUNTERS) - Show hub status. The console is easy to use; just type in one of the commands such as reset, status, or help. (As a shortcut, you can enter only the first two letters of the command, e.
Troubleshooting Counter Definition Readable 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. Errored The count of frames received with any of the following errors: FCS, bad symbol, symbol balance, undersize, or bad end-of-packet marker. IPM The count of frames received with an invalid packet marker.

Recommended Cables Recommended Cables This page cables that have been tested and verified for use with the HP AdvanceStack 100VG hubs. 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 Incorrectly wired cabling is the most common cause of problems for LAN communications. HP recommends that you work with a qualified LAN cable installer for assistance with your cabling requirements.
Twisted-Pair Cable/Connector Pin-Outs 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 “straightthrough” 4-pair twisted-pair cable. The twisted-pair wires must be twisted through the entire length of the cable. The illustration below shows the RJ-45 pin connections, color code, and pair configuration for an 100VG LAN cable (unbundled) that conforms to the EIA/TIA 568B wiring standard for a straight-through cable.
