Installing the Hub This chapter describes how to install the hub. Topics in this chapter include verifying included parts installing the transceiver module verifying the hub operates correctly mounting the hub connecting the hub to your network connecting hubs together...
Installing the Hub Installing Your Hub Installing Your Hub To install and configure your hub, you must complete six basic tasks. They are: locating and verifying the necessary parts installing a transceiver module connecting the hub to a power source mounting the hub connecting the hub to your network 1.
Installing the Hub Installing Your Hub external transceiver). Because of these widths, clearance in front of your hub may be a factor in the placement of the device or stack that contains protruding transceiver connectors, for example, a BNC connectors. Inspect your installation site and identify whether enough room will be available for the installed transceiver to be connected.
Installing the Hub Installing Your Hub Check the LEDs on the hub’s front panel. When the hub is powered on, it performs a power-on self test. See the table below for the LED self test time that occurs during the self test. Note the upper number is for the HP J3300A/HP J3302A and the lower number is for the HP J3301A/HP J3303A.
Installing the Hub Installing Your Hub Note that once you have connected cables to the hub, an AUI transceiver LED or twisted pair Port LED stays on if link beat has been detected at the port from an incoming device and the port is enabled. A Port LED turns off if link beat is not detected.
Installing the Hub Installing Your Hub Using a Phillips Crosshead No. 2 screwdriver, attach the mounting brackets to the hub with No. M4 (5/16") silver screws (included in the accessory kit). Figure 1-2. Hub-to-Bracket Assembly Position the hub in the rack or cabinet and slide it up or down until the rack holes line up with the bracket holes.
Installing the Hub Installing Your Hub Figure 1-3. Hub-to-Rack Assembly Wall Mounting Using a Phillips (crosshead) No. 2 screwdriver, attach the mounting brackets to the hub with 8-mm (approximately 5/16") M4 screws included in the accessory kit. Then attach the hub to a wood surface (minimum 1/2-inch plywood or equivalent) with No.
Installing the Hub Installing Your Hub 5. Connect the hub to your network Connect the hub to an AC power source. With the hub mounted, you are now ready to connect the hub to your network. Typical hub connections are: hub-to-device connections.
Installing the Hub Installing Your Hub Connecting Hubs Together Twisted-Pair Cascade Connections To expand your network, the hub can be connected to other hubs with straight- through cable by using the Media Dependent Interface (MDI/MDI-X) switch. The MDI/MDI-X switch controls how the signals are sent through the twisted- pair cable connected to Port 1.
Installing the Hub Installing Your Hub In the following illustration, the top hub in the stack is connected to two end nodes and to a second hub. Note the second hub shows Port 1 connecting to a PC, using a straight through twisted pair cable with the port in the MDI-X position.
Installing the Hub Installing Your Hub ThinLAN Connections With an HP ThinLAN Transceiver Module for 10Base2 networks installed in the transceiver slot, you can connect your hub or a stack of hubs to a 10Base- 2 ThinLAN network. The following illustration shows a hub with an HP ThinLAN Transceiver.
Installing the Hub Installing Your Hub N o t e Each ThinLAN cable segment must be terminated using a 50-ohm terminator at each end. In the illustration above, a 50-ohm terminator is placed at each end of the cable segment. Connecting the HP ProCurve 10Base-T Hubs to a Fiber-Optic Backbone With a Fiber-Optic transceiver for 10Base-FL networks, you can connect your...
Troubleshooting This chapter describes ways to troubleshoot the hub. Topics covered are: troubleshooting approaches using a checklist to diagnose the hub diagnosing with the LEDs hub maintenance tasks Troubleshooting Approaches You can diagnose problems on all HP ProCurve 10Base-T Hubs by checking the LEDs on the front of the hub as described in the section, “Diagnosing with the LEDs”...
Troubleshooting Diagnosing with the LEDs Use the following table to diagnose the problem with your HP ProCurve 10Base-T Hub. Problem Solution How do I reset the hub? You can reset the hub three five different ways: • From the device, remove the plug on the power cord from the power source or the hub and reconnect it.
Troubleshooting Most problems with the hub can be diagnosed using the LEDs on its front panel. The following section describes the normal LED pattern during self- test, and LED patterns that indicate error conditions on the hub. Interpreting LED Status Two types of LEDs exist on the hub.
Troubleshooting Interpreting Port Status LEDs The following table provides LED port information for the HP J3301A and the HP J3303A. Color Meaning of LED Twisted-pair Green On indicates Link Beat is detected from the attached node and Ports the port is enabled on the HP J3301A and HP J3303A. Off indicates the port is not receiving the link beat signal from the attached node.
Troubleshooting LED Operation The tables on the following pages list the hub’s LEDs, their possible states, and diagnostic tips to resolve any error conditions. LED patterns indicating problems Diagnostic Tips Power Coll Port LED Fault Check cabling on the indicated port all the way out to the device attached to that port.
Troubleshooting Hub Maintenance Tasks There are several hub maintenance tasks you can perform. They include: testing the hub only clearing a password from the ASCII console running connectivity tests Each of these tasks is described in the following sections. Testing the Hub Only If you believe that the hub is not operating correctly, you can test it to determine normal operation in two ways: pressing the Reset Button.
Troubleshooting Running Connectivity Tests Both the hub and cabling can be tested by running an end-to-end communica- tions test—a test that sends known data from one network device to another through the hub—such that you can verify that the data was correctly trans- mitted between the devices.
Troubleshooting Obtaining Firmware Enhancements In the future, Hewlett-Packard may provide improvements to the HP ProCurve 10Base-T Hub 12M and the HP ProCurve 10Base-T Hub 24M through firmware upgrades. The upgrade code can be downloaded from a PC attached to the hub’s RS-232 port or over the network.

Safety and Regulatory Statements This chapter covers the following topics: mounting precautions power precautions safety statements regulatory statements Declaration of Conformity Mounting Precautions When you put a hub into a rack, follow these mounting precautions: The rack or cabinet should be adequately secured to prevent it from becoming unstable and/or falling over.
N o t e 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. The mark is your assurance that the power cord can be used safely with the hub.
