Roadhw0.bk : ROADHW1.FM Page 1 Thursday, May 28, 1998 5:40 PM 1 The HP ProCurve J3294A and HP J3295A 10/100 hubs are low-cost multiport, dual-speed, 10- and 100Mbps repeaters that can be used to build highperformance workgroup networks. These hubs are completely autosensing and autonegotiating devices that provide the flexibility of adjusting to different speed settings. The hubs are always half-duplex.

Roadhw0.bk : ROADHW1.FM Page 3 Thursday, May 28, 1998 5:40 PM Introducing the HP ProCurve 10/100 Hubs Front of the Hubs The HP 10/100 Network Ports are as follows: 12 or 24 10/100Base-T RJ-45 ports ■ ■ one MDI/MDI-X port (port 1). All the fixed twisted-pair ports are wired as MDI-X. Therefore, to connect end nodes or other MDI-type devices to these ports, use “straight-through” twistedpair cable; to connect hubs, switches, or other MDI-X-type devices to these ports, use “crossover” twisted-pair cable.

Roadhw0.bk : ROADHW2.FM Page 1 Thursday, May 28, 1998 5:40 PM 2 Installing the Hub The HP J3294A and HP J3295A 10/100 hubs are easy-to-install units. Each comes with an accessory kit (HP P/N 5183-7210) that includes the brackets for mounting the hub in a standard 19-inch telco rack or an equipment cabinet, or on a wall, and it comes with rubber feet so it can be securely located on a horizontal surface. The brackets are designed to allow mounting the hub in a variety of orientations.
Roadhw0.bk : ROADHW2.FM Page 2 Thursday, May 28, 1998 5:40 PM Installing the Hub Installation Summary Installation Summary Installing the Hub Follow these easy steps to install your hub. The rest of this chapter provides details on these steps. 1. Prepare the installation site. Make sure that the physical environment into which you will be installing the hub is properly prepared including having the correct network cabling ready to connect to the hub, and having a good location for the hub.
Roadhw0.bk : ROADHW2.FM Page 3 Thursday, May 28, 1998 5:40 PM Installing the Hub Installation Summary Installation Precautions The following are power requirement precautions. • If your installation requires a different power cord than the one supplied with the hub, be sure to use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country.
Roadhw0.bk : ROADHW2.FM Page 4 Thursday, May 28, 1998 5:40 PM Installing the Hub Installation Summary 1. Prepare the Installation Site Installing the Hub ■ ■ Cabling Infrastructure - Ensure that the cabling infrastructure meets the necessary network specifications.
Roadhw0.bk : ROADHW2.FM Page 5 Thursday, May 28, 1998 5:40 PM Installing the Hub Installation Summary 2. Verify the Hub Operates Correctly Before mounting the hub in its network location, you should first verify that it is working properly by plugging it into a power source and verifying that it passes its self test. 1. Connect the power cord supplied with the hub to the power connector on the back of the hub, and then into a properly grounded electrical outlet.
Roadhw0.bk : ROADHW2.FM Page 6 Thursday, May 28, 1998 5:40 PM Installing the Hub Installation Summary If the LED display is different than what is described above, especially if the Fault LED stays on for more than 3 seconds, the self test has not completed correctly. Refer to chapter 3, “Troubleshooting” for diagnostic help. 3. Mount the Hub Make sure you are ready to mount the hub in a stable location.
Roadhw0.bk : ROADHW2.FM Page 7 Thursday, May 28, 1998 5:40 PM Installing the Hub Installation Summary Partially install a screw into the top hole of a close (0.5-inch) pair on both sides of the rack 3. Place the hub in the rack and lower it so the notches in the bottom of the bracket slide onto the screws. Tighten these screws-be careful not to overtighten them. 4. Install the other number 12-24 screw into the upper hole in each bracket. Tighten these screws-be careful not to overtighten them.
Roadhw0.bk : ROADHW2.FM Page 8 Thursday, May 28, 1998 5:40 PM Installing the Hub Installing the Hub Installation Summary Wall Mounting You can mount the hub on a wall. Note that the hub should be mounted only to a wall or wood surface that is at least 1/2-inch plywood or its equivalent. 1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting brackets to the hub with the included 10-mm M4 screws. 2.
Roadhw0.bk : ROADHW2.FM Page 9 Thursday, May 28, 1998 5:40 PM Installing the Hub Installation Summary 4. Connect the Hub to a Power Source 1. Plug the included power cord into the hub’s power connector and into a nearby AC power source. 2. Re-check the LEDs during self test. See “LED Behavior” on page 2-5. For power precautions, see the section, “Installation Precautions” earlier in this chapter. The HP 10/100 hubs do not have a power switch.

Roadhw0.bk : ROADHW3.FM Page 1 Thursday, May 28, 1998 5:40 PM 3 Troubleshooting This chapter describes how to troubleshoot your HP 10/100 hub. This chapter describes the following: ■ basic troubleshooting tips ■ diagnosing with the LEDs ■ Hardware Diagnostic tests ■ HP Customer Support Services Basic Troubleshooting Tips Most problems are caused by the following situations: ■ Incorrect hub-to-switch or hub-to-hub connections. Check your cable type.
Roadhw0.bk : ROADHW3.FM Page 2 Thursday, May 28, 1998 5:40 PM Troubleshooting Troubleshooting Basic Troubleshooting Tips ■ Non-standard cables. Non-standard and miswired cables may cause network collisions and noise, and can seriously impair network performance. 100Base-T networks are more sensitive to miswired cables than 10Base-T networks. Use a new correctly-wired cable or compare your cable to the cable in Appendix B, “Cables and Connectors” for pinouts and correct cable wiring.
