. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-1 Chapter 1 Overview The Compaq HB1004 10Base-T Ethernet Hub is a stand-alone, intelligent, 4 port hub. If offers an SNMP V1-compliant firmware agent. The HB1004 can be monitored and controlled through a network management station. In addition, you can also cascade the hub to additional 10Mb/s hubs or 10/100Mb/s switches. The hub supports both in-band and out-of-band management.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-3 Hub Components This section provides an overview of the Compaq HB1004 hub’s components including the LED indicators, RJ-45 ports, and the serial COM port. Figure 1-1 shows the hub’s front panel. Figure 1-1 Compaq HB1004 10Base-T Ethernet Hub Front Panel RJ-45 Ports The hub’s four RJ-45 ports allow connections to workstations and servers in a 10Base-T network via UTP cabling.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-4 Overview Unit LEDs The unit-level LEDs on the HB1004 indicate the status of the power supply and the percentage of use and collisions on the hub.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1-5 Port LEDs There are two LEDs for each port to indicate link/activity and partition/disable on the ports.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-1 Chapter 2 Installation This chapter provides information to help you prepare for and install the hub and connect the hub to the network. Mounting the Hub You can place this hub directly on a desktop or mount it in a rack. Before you start installing the hub, make sure you can provide the right operating environment, including power requirements, sufficient physical space, and proximity to other network devices you want to connect.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-2 Installation Mounting the Hub in a Rack To mount the hub in a rack, follow these steps: 1. Use a standard EIA 19 inch rack 2. Use the brackets and screws supplied in the rack mounting kit 3. Use a cross-head screwdriver to attach the brackets to the side of the hub Figure 2-1 Attaching the Mounting Brackets 4.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-3 Connecting the Hub System The Compaq HB1004 hub has four RJ-45 ports, one of which serves as an MDI/MDI-X port. Making a Connection via an MDI-X Port You can connect any RJ-45 (MDI-X) station port on the hub to any device that uses a standard network interface such as a PC or server. You can also connect to an MDI-X port of a network interconnection device such as a bridge or router by using a cross-over cable. 1.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-4 Installation WARNING: Do not plug a phone jack connector into any RJ-45 port. This may damage the hub. Instead, use only twisted-pair cables with RJ-45 connectors. NOTES: 1. Make sure each twisted-pair cable does not exceed 100 meters (328 feet) 2. When using Port 4 as an MDI-X port, set the port selection switch to MDI-X Making a Connection via the MDI/MDI-X Port (Port 4) 1.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-5 I O Figure 2-4 Connecting the Power Cord 3. Check the LED marked PWR on the front panel to see if it is on. The unit will automatically select the setting that matches the connected input voltage. Therefore, no additional adjustments are necessary when connecting it to any input voltage within the specified range. See Appendix A for power requirements. 4. The hub performs a self-diagnostic test upon power-on.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-6 Installation Diagnostic Tests After power on, the hub automatically performs a diagnostic self-test. During this test, port status LEDs indicate the success or failure of each test. The system tests each component one at a time. At the completion of the test, if no diagnostic LEDs are lit, then all components passed the test. If a component fails the test, the corresponding LED will continue blinking.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-7 Verifying Hub and Port Status After the hub completes the POST, you can check hub activity and each connection by comparing the indicators with Table 2-2.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-8 Installation Applications This hub is not only designed to provide network access for 10Mb/s connections, but also to provide options in setting up network connections. It can be used as a simple stand-alone hub or can be cascaded to any compatible hub or switch. A sample configuration diagram is shown in Figure 2-7.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-1 Chapter 3 Setup and Configuration Preparing for Configuration Management There are two methods for configuring the Compaq HB1004 - using the out-ofband program or using in-band network management software (not supplied). The diskette included with the Compaq HB1004 contains the menu-driven Compaq HB1004 System Configuration Program. To use this program, make a direct PC or modem connection to the serial port on the front of the hub.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-2 Setup and Configuration Figure 3-1. Out-of-Band Connection Using an Onsite PC Modem Connection Connect the COM port on the hub to the serial port on the modem. Use the communications cable provided with the hub and DB9/25 to RJ-45 converters as needed. At the remote site, connect the PC’s COM port to the remote modem. Configure the PC’s COM port and the modems for 9600 baud, 8 bits, no parity, and one stop bit (9600, 8, N, 1).
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-3 In-Band Connection You can configure and manage the hub through the network (in-band) by using a network management application (not supplied). However, before you can access the hub with an in-band connection you must use an out-of-band connection and the Compaq HB1004 System Configuration Program to configure the hub’s IP address, subnet mask, and default gateway.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-4 Setup and Configuration To start the Compaq HB1004 System Configuration Program from Windows: 1. Insert the Compaq HB1004 Configuration Program diskette into the floppy disk drive 2. In File Manager or Program Manager, click File, then click Run 3. Type A:\HB1004CP for Drive A or B:\HB1004CP for Drive B in the Command Line box 4. Click the OK button to open the program and display the communication dialog box shown in Figure 3-3.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-5 NOTE: The Compaq HB1004 System Configuration Program allows selection of COM Ports 1, 2, 3 or 4 and assumes the normal default IRQ for the appropriate port (i.e. COM1 is IRQ4, COM2 is IRQ3, COM3 is IRQ4 and COM4 is IRQ3). If your communication port is configured differently, it is necessary to specify the correct IRQ for that port. If this is the case, type: A:\HB1004CP /i[irq#] or B:\HB1004CP /i[irq#] in the Open box.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-6 Setup and Configuration Figure 3-4 DCE/DTE Dialog Box 3. Select the appropriate option in the DCE/DTE dialog box: Q Terminal Channel for local hookup, opens the Main Menu as shown in Figure 3-6. Q Modem Channel for remote connection via modems. If you are using a modem connection, select Modem Channel to open the Phone List menu as shown in Figure 3-5. Enter the phone number and press to start the dialing mechanism.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-7 Once the connection is established, the Main Menu for out-of-band configuration appears as shown in Figure 3-6. Figure 3-6 Main Menu 4.
