Mount the Hub

After the modules are inserted, you are ready to put the hub in a stable location. The Switching Hub can be mounted in three ways:

■

■

■ on a table in a rack or cabinet on a wall

Hub on a Table - no tools needed

Sturdy table in an isolated area.

Hub in a Rack or Cabinet

The Switching Hub is designed to be mounted in any EIA-standard 19-inch telco equipment rack. To order a rack for your hub, call HP at 1-800-538-8787 to order product number HP 46298D. For your safety, read the mounting precautions in appendix C, “Safety and Regulatory” in the Switching Hub

Reference before mounting a hub.

1.

Attach the mounting brackets to the hub with the included 10-mm M4 screws.

4



2.

Partially install a screw (5/8-inch number 12-24) into the top hole of a pair of holes 0.5 inches apart in each rack/cabinet upright. Tighten each screw two turns. Ensure that the screws in each upright are at the same level.

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.

Upper hole in the bracket

Lower notch in the bracket

5



4.

Install the other number 12-24 screw into the upper hole in each bracket. Tighten these screwsbe careful not to overtighten.

Install additional screw

6



Mounting the Hub on a Wall

You can put one hub on a wall or stack two hubs together on a wall. Note that a hub should be mounted only to a wall or wood surface that is at least 1/2-inch plywood or its equivalent.

Attach the hub to the wall or wood surface with 5/8-inch number 12 wood screws (not included):

One hub on a wall:

Two hubs on a wall:

7



Connecting the Switching Hubs Together with Extender Cable

Attach the included Extender Cable from one hub to another:

Extender Cable

(can be installed in this orientation only)

The Extender Cable provides communication between the hubs. If you add an HP Management

Module, network management travels over this cable also. You can connect an Extender Cable when the power is on or off. Never leave an Extender Cable unconnected at one end.

L o n g e r C a b l e s O p t i o n

If you need longer cable, order Long Extender Cable 71 cm (28 inch) (5182-9869) from

1-800-538-8787. Note that a maximum of two Long Extender Cables are allowed per stack.

Verify That the Hub Works Correctly

1.

(Optional.) This product is supported by the HP J2962A Redundant Power Supply (RPS). If you have this HP RPS, connect the RPS to the hub now.

2.

If you are not using an RPS, plug the included power cord into the hub’s power cord receptacle and into an AC power source as shown below. power receptacle on the back of the hub

3.

Check the LEDs during self test. Initially, all LEDs are on except the Expansion Slot LEDs and

Transceiver if an Expansion Slot Module or transceiver is not installed. After the two second self test (or 10 second self test with Management Module), the following LEDs are on:

Power on

RPS on if Redundant Power Supply is connected

If the above behavior does not happen, use this troubleshooting information to diagnose the problem:

Condition Diagnostic Tip

Power LED is OFF Check power cord and power source connections. If connections are secure, then try a different outlet, or try a different power cord to see if the power cord is the problem.

RPS LED is OFF and should be ON

The hub is not receiving power from the Redundant Power Supply (RPS) or the cable connection is loose. If you have an RPS connected, check the cable connections. Try connecting the RPS to a different outlet.

Module Fault LED is ON

Turn off the hub and reinsert this module making sure the screws are tightened. If the Fault LED is still on, insert the module into a different hub.

Hub Fault LED is

ON

A hub or slot module hardware failure was detected during self-test. Self-test does not complete so the LEDs will stay on longer than 60 seconds. If you have installed a Switch Module in the stack, verify that a Management Module is also installed in that stack.

Power cycle the hub. If this condition persists, the hub may have to be replaced. Contact your

HP-authorized dealer or HP representative for assistance.

Hub Fault LED is flashing

Corresponding LED (such as RPS or port) will also flash at the same time. Make sure SQE is disabled for the transceiver module if the AUI/Xcvr LED is flashing.

If the above tips do not help, see chapter 3, “Troubleshooting” in the Switching Hubs Reference

Manual for additional information.

Connecting Network Cables

Using RJ-45 Connectors

To connect:

Push the RJ-45 plug into the RJ-45 jack until the tab on the plug clicks into place.

When power is on for the hub and the connected device, the Port LED should light to confirm a powered-on device (e.g., end node) is at the other end of the cable.

To disconnect:

Press the small tab on the plug and pull the plug out of the jack.

RJ-45 plug unshielded twisted-pair cable

Category 3, 4, or 5

Cat 3, 4 maximum distance: 100 meters

Cat 5 maximum distance: 150 meters

If the Port LED is not on, use this table to solve the problem:

Condition Diagnostic Tip

Port LED is still off when a cable is connected

Try:

- For the indicated port, verify that both ends of the cabling are snug: hub and end node.

- Verify the end node and hub are both on.

- A different port or a different cable.

If you have installed the Management Module, use the ASCII console or HP AdvanceStack Assistant to determine the state of the port and re-enable the port if desired.

N o t e

Do not use twisted-pair, thin coax, or fiber cables to make a Switching Hub to Switching Hub connection across the stack. The Extender Cable is for Switching Hub to Switching Hub connections only.

10



Using Telco Connectors with the Hub-24T

If you prefer to make your twisted-pair connections through a cross-connect block, wiring closet, or other intermediary connection, the Hub-24T has industry-standard 50-pin telco connectors.

Devices connected to the hub’s

50-pin telco connector through a cross-connect block.

11



To use a telco connector:

1. Attach the mounting hook with the 1/2-inch 4-40 screw.

2. Insert hook in slot on the hub’s face.

3. Pivot the telco plug onto the connector and press into place.

4. Tighten the screw on the telco plug. Be careful not to overtighten the

screw.

To remove a telco connector, reverse this process.

AUI/Xcvr Slot

An optional transceiver module can be installed in the hub’s AUI/Xcvr slot to provide additional connectivity choices, including:

HP Fiber-Optic Transceiver Module (HP J2606A)

Maximum Distance: 1000 meters

HP Twisted-Pair Transceiver Module (HP J2607A

Category 3, 4 maximum Distance: 100 meters

Category 5 maximum Distance: 150 meters

HP ThinLAN Transceiver Module (HP J2608A)

Maximum distance: 185 meters

HP AUI Port Module (HP J2609A)

(to attach external transceivers)

Do not use this port for Switching Hub to Switching Hub connections in the stack.

See the documentation accompanying the optional transceiver modules for cabling configurations for those modules. To use an external transceiver on a hub, the SQE Test and Loopback Test options, if present,

12


HP AdvanceStack 10BT Switching Hubs Installation Guide must be disabled on the transceiver.

Cable Management

The HP Switching Hubs have been designed to help you with the problem of managing your network cables. On both sides of the front of each hub are two holes that accept a cable tie to tie-wrap your cables: cable tie

Where to Go From Here

Your hub is now correctly installed and is able to send and receives data between end nodes, servers, and printers. Depending on your setup, use this table to determine what steps need to be taken next.

Your Hub Setup Detailed Description

One hub or stack of 2 or more hubs with:

- No Management Module

- No Switch Module

Communication Status What You Need to Do

All users are on segment 1 and can communicate together.

No software configuration needed.

If Act or Col LEDs are on all of the time, add a Management Module and external switch or Switch Module to distribute ports evenly over the four segments.

Mgmt.

Switch in back

Stack of 2 or more hubs with:

- Management Module

- Switch Module

Mgmt

All users are distributed evenly over segments 1, 2, 3, and 4 and can communicate together.

Stack of one or more hubs with Management Module only

All users are on segment 1 and can communicate together.

No software configuration or optimization needed.

If Act and Col LEDs are on most of the time, segment your stack by either:

-adding a Switch Module

-adding more LAN adapters to the

servers.

- adding an external switch.

If you only add a Management Module and move the ports to other segments in software, remember that users cannot communicate between the segments.

Add an external switch or Switch Module to this stack for communication between all the segments.

If you need to set the IP address, see the Management Module manual for information on how to use the ASCII console or HP AdvanceStack Assistant. For a Novell Netware network, no configuration is necessary.
