Introducing the Switch 408

Switch Operation Overview matically and stored in the Switch 408’s 1000-entry address table. The switch also identifies the number of the port on which each address is learned so it knows the relative network location of each device.

Forwarding, Filtering, Flooding.

When the switch receives a packet, it determines the destination address, and looks for the address in the address table. Based on the port location of that address, the switch then determines whether to forward, filter-out, or flood the packet.

forward

- if the destination address is on a different port than the one on which the packet was received, the packet is forwarded to the destination port and on to the destination device.

filter out

- if the destination address is on the same port as the one on which the packet was received, the packet is filtered out.

The switch thereby isolates local traffic so the rest of the network connected to the switch does not use bandwidth dealing with unnecessary traffic.

flood

- whenever a new destination address is found in a packet received on a port, the destination address will not yet be in the switch’s address table and the Switch 408 cannot know whether to forward or filter out the packet. In this case, it sends the packet to all the other switch ports. This is referred to as “flooding”.

When the destination device receives the packet, it replies, and the switch learns the new address from the reply packet. Then, all future packets destined for that address are forwarded or filtered out appropriately.

Network Moves and Changes.

When devices are moved in the network, and become connected to a different switch port, the Switch

408 automatically recognizes the change and updates the address table with the new port locations of the devices. Communication with the connected devices is thereby automatically maintained.

Installation Procedures

Installation Procedures

Summary

Follow these easy steps to install your switch. The rest of this chapter provides details on these steps.

1.

Prepare the installation site.

Make sure of the following:

the network cabling is the correct type and length. See page

2-5.

the network topology is correct. See page 2-10.

• no devices connected to the switch have a fixed full-duplex configuration (they must be able to auto-negotiate the duplex

mode or be fixed at half duplex). See page 2-4.

See page 2-3 for installation precautions.

2.

Verify that the switch passes its self test.

This is a simple process of plugging the switch into a power source and observing that the LEDs on the switch’s front panel show correct operation.

See page 2-7.

3.

Mount the switch.

The Switch 408 can be mounted on any horizontal surface. The optional mounting kit (5183-7210) provides other options including mounting two switch units sideby-side in a standard 19-inch telco rack or equipment cabinet.

4.

Connect power to the switch.

Once the switch is mounted,

plug in the AC power adapter. See page 2-9.

5.

Connect the network devices.

Using the appropriate network cables, connect computers, servers, printers and other peripherals, and other network devices including other switches, hubs,

or routers to the switch ports. See page 2-9.

At this point, the switch is fully installed and your network should be up and running. See the rest of this chapter if you need more detailed information on any of these installation steps.

honda.book Page 3 Wednesday, April 18, 2001 2:50 PM

Installing the Switch 408

Installation Procedures

Installation Precautions:

Follow these precautions when installing your Switch 408.

Cautions

Make sure that you use the power adapter supplied with the switch to connect it to an AC power source.

■ When installing the switch, since the unit does not have an On/Off power switch, an AC power outlet must be located near the switch and should be easily accessible in case the switch needs to be powered off.

Make sure that the switch does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add together the amperage ratings of all devices installed on the same circuit as the switch and compare the total with the rating limit for the circuit. The maximum amperage ratings are usually printed on the devices near the AC power connectors or power adapter connectors.

■ Do not install the switch in an environment where the operating ambient temperature might exceed 55

°C

(131

°F).

■ Make sure the air flow around the sides of the switch is not restricted.

■ If you rack mount the Switch 408 (using the mounting kit,

5183-7210), the rack or cabinet should be adequately secured to prevent it from becoming unstable and/or falling over. Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest device at the bottom and progressively lighter devices installed above.

Installing the Switch 408

Installation Procedures

Connect no devices that have a fixed full-duplex configuration

. Because the switch 408 complies with the IEEE 802.3u standard, if a device connected to the switch has a fixed configuration of full duplex, the device will not connect correctly to the switch. Make sure all devices connected to the Switch 408 are configured to auto negotiate, or are configured to connect at half duplex. For more information, see the “Basic Trouble-

shooting Tips” in chapter 3, “Troubleshooting”.

1. Prepare the Installation Site

Cabling Infrastructure

- Make sure that the cabling infrastructure meets the necessary network specifications. Because of the

HP Auto-MDIX

feature, for connections to end nodes

(computers, servers, printers and other peripherals), or connections to hubs or other switches, you can use “straight-through” cables. “Crossover” cables can also be used for any of these connections. See the following table for cable types and lengths,

and see appendix B, “Cables and Connectors” for more informa-

tion:

2. Verify the Switch Passes Its Self Test

Before mounting the switch in its network location, you should first check that it is working properly by plugging it into a power source and verifying that it passes its self test.

1.

Connect the adapter’s power cord to the power connector on the back of the switch, and then plug the AC power adapter into a nearby properly grounded electrical outlet.

Connect power cord to the power connector

Note

The Switch 408 does not have a power switch. It is powered on when the AC power adapter is connected to the switch and to a power source.

Caution Use only the AC power adapter supplied with the switch. Use of other adapters, including those that came with other HP network products, may result in damage to the equipment.

2.

Check the LEDs on the switch. The LED behavior is described on the next page.

Installation Procedures

Switch port LEDs

Power and Fault LEDs

When the switch is powered on, it performs its diagnostic self test. The self test takes approximately 3 seconds to complete.

LED Behavior:

During the self test:

• All the switch and port LEDs are on.

When the self test completes successfully:

• The Power LED stays on and the Fault LED goes off.

• The port LEDs (Link/Act, FDx, and 100) go into their normal operational mode.

If the LED display is different than what is described above, especially if the Fault LED stays on for more than 5 seconds, the

self test has not completed correctly. Refer to chapter 3, “Trou-

bleshooting” for diagnostic help.

Installation Procedures

3. Mount the Switch

After you have verified that the switch passes its self test, you are ready to mount the switch in a stable location. The Switch 408 can be mounted in these ways: on a horizontal surface in a rack or cabinet, or on a wall (requires optional bracket kit)

Horizontal Surface Mounting

Attach the supplied rubber feet to the bottom of the switch, then place the switch on a table or other horizontal surface. Use a sturdy surface in an uncluttered area. You may want to secure the networking cables and switch power cord to the table legs or other part of the surface structure to help prevent people from tripping over the cords.

Note

Make sure the air flow is not restricted around the sides of the switch.

Rack or Wall Mounting

Using the optional bracket kit (5183-7210), two Switch 408 units can be mounted together in any EIA-standard 19-inch telco rack or in an equipment cabinet such as a server cabinet. The switch brackets can also be used to mount the switch on a wall or under a horizontal surface. Installation instructions are included with the bracket kit.

Caution

For safe operation, please read the Installation

Precautions on page 2-3 before mounting the switch.

Sample Network Topologies

This section shows you two sample network topologies in which the

Switch 408 is implemented.

Note

Make sure the network into which you are installing the

Switch 408 has a valid topology: there should be no loops in the data paths connected to the switch, and all twistedpair connections should be no more than 100 meters.

In general, the Switch 408 is designed to be used as a desktop switch, but it can also be used as a segment switch. That is, it can be used for interconnecting network segments—simply connect the network hubs that form those segments to the switch.

In the illustration above, two Ethernet hubs with PCs, printers, and local servers attached, are both connected to a Switch 408. The devices attached to the two hubs can now communicate with each other through the switch. They can also all communicate with the server that is connected to the switch. Make sure connections from servers to the Switch 408 are at 100 Mbps to minimize network congestion to the servers.

2-11

honda.book Page 12 Wednesday, April 18, 2001 2:50 PM

Installing the Switch 408

Sample Network Topologies

Note that because of the HP Auto-MDIX feature, all twisted-pair connections between the switch and the MDI-X ports or MDI ports on hubs, and the connections to the end nodes and the servers can be through “straight-through” cables. You can also use “crossover” cables for these connections. In either case, the Switch 408 automatically adjusts to the type of cable used and to the type of device at the other end of the connection.

The 100 Mbps connection to the server and any other 100 Mbps connections must be through category 5 or better cable.

Troubleshooting

This chapter describes how to troubleshoot your Switch 408 including the following:

basic troubleshooting tips (page 3-1)

diagnosing with the LEDs (page 3-3)

hardware diagnostic tests (page 3-5)

HP Customer Support Services (page 3-6)

Basic Troubleshooting Tips

Most problems are caused by the following situations:

Connecting to devices with a fixed full-duplex configuration

. The Switch 408 ports are set to auto-negotiate the link characteristics. That is, when connecting to attached devices, the switch will operate in one of two ways to determine the link speed and the communication mode (half duplex or full duplex):

• if the connected device is also set to auto negotiate, the switch will automatically negotiate both link speed and communication mode

• if the connected device has a fixed configuration, for example

(100 Mbps, and half or full duplex), the switch will automatically sense the link speed, but will default to a communication mode of half duplex

3-1

honda.book Page 2 Wednesday, April 18, 2001 2:50 PM

Troubleshooting

Basic Troubleshooting Tips

Because the Switch 408 behaves in this way (in compliance with the IEEE 802.3u standard), if a device connected to the switch has a fixed configuration at full duplex, the device will not connect correctly to the Switch 408. The result will be high error rates and high collision rates, and very inefficient communications between the switch and the device.

Make sure that all devices connected to the Switch 408 are configured to auto negotiate, or are configured to connect at half duplex (all hubs are configured this way, for example).

Faulty or loose cables.

Look for loose or obviously faulty connections. If they appear to be OK, make sure the connections are secure. If that does not correct the problem, try a different cable.

Non-standard cables.

Non-standard and miswired cables may cause numerous network collisions and other network problems, and can seriously impair network performance. 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. A category 5 cable tester is a recommended tool for every 100Base-T network installation.

Improper Network Topologies.

It is important to make sure you have a valid network topology. Common topology faults include excessive cable length and too many repeaters (hubs) between end nodes. If you have network problems after recent changes to the network, change back to the previous topology. If you no longer experience the problems, the new topology is probably at fault. Refer to the Network Design Guide for topology configuration guidelines. This guide can be found online at the

HP World Wide Web site for networking products, http://

www.hp.com/go/hpprocurve

. You can find it quickly by searching for “Network Design Guide”.

Troubleshooting

Diagnosing With the LEDs

In addition, you should make sure that your network topology contains no data path loops. Between any two end nodes, there should be only one active cabling path at any time. Data path loops will cause broadcast storms that will severely impact your network performance.

Diagnosing With the LEDs

Table 3-1 shows LED patterns on the switch that indicate problem conditions.

1.

Troubleshooting

Diagnosing With the LEDs

Diagnostic Tips:

Tip

Number Problem

The switch’s power adapter is not plugged into an active

AC power source, or the power adapter may have failed.

A switch hardware failure was detected during self test.

The network connection is not working properly.

Solution

1. Verify that the AC power adapter is plugged into an active power source and to the switch.

Make sure these connections are snug.

2. Try power cycling the switch by unplugging and plugging in the power.

3. If the Power LED is still not on, verify that the

AC power source works by plugging another device into the outlet. Or try plugging the switch into a different outlet.

If this condition persists, the switch’s power adapter may have failed. Call your HP-authorized

LAN dealer, or use the electronic support services from HP to get assistance. See the

Customer Support/Warranty booklet for more information.

Try power cycling the switch. If the fault indication reoccurs, the switch may have failed.

Call your HP-authorized LAN dealer, or use the electronic support services from HP to get assistance. See the Customer Support/Warranty card for more information.

Try the following procedures:

• For the indicated port, verify that both ends of the cabling, at the switch and the connected device, are secure.

• Verify the connected device and switch are both powered on and operating correctly.

• Verify that the connected devices comply with the appropriate IEEE 802.3 standard, including transmission of the Link signal. See “Testing

Twisted-Pair Cabling” on page 3-5.

• If the other procedures don’t resolve the problem, try using a different port or a different cable.

Troubleshooting

Hardware Diagnostic Tests

Hardware Diagnostic Tests

Testing the Switch by Resetting It

If you believe that the switch is not operating correctly, you can reset the switch to test its circuitry. To reset the switch, unplug and plug in the adapter’s power cord (power cycling).

Power cycling causes the switch to perform its power-on self-test, and almost always will resolve any temporary operational problems.

Checking the Switch LEDs

The self-test passes if the Fault LED on the front of the switch goes off after approximately 3 seconds. If this LED stays on longer than 5 seconds, an error condition has been detected on the switch.

See “Diagnosing With the LEDs” on page 3-3 for information on

interpreting the LED patterns.

Testing Twisted-Pair Cabling

If you think the cable should work but still isn’t working, it may not be compatible with the IEEE 802.3 Type 10Base-T or 100Base-TX standards. The twisted-pair cables attached to the Switch 408 must be compatible with these standards. To verify that your cable is compatible with these standards, use a qualified cable test device.

HP also offers a wire testing service. Contact your HP-authorized LAN dealer or your local HP sales office for more information.

Troubleshooting

HP Customer Support Services

Testing End-to-End Network Communications

Both the switch and the cabling can be tested by running an end-toend communications test -- a test that sends known data from one network device to another through the switch. For example, if you have two PCs on the network, both connected to the switch, you can use a link-level packet test (link test) or Ping test to verify that the entire communication path between the two PCs is functioning correctly. See your LAN adapter documentation for more information on running a link test or Ping test.

HP Customer Support Services

If you are still having trouble with your switch, Hewlett-Packard offers support 24 hours a day, seven days a week through the use of a number of automated electronic services. See the Customer

Support/Warranty booklet that came with your switch for information on how to use these services to get technical support. The HP networking products World Wide Web site,

http://www.hp.com/go/hpprocurve

also provides up-to-date support information.

Additionally, your HP-authorized network reseller can provide you with assistance, both with services that they offer and with services offered by HP.

Cables and Connectors

This appendix includes minimum pin-out information and specifications for cables that should be used with the Switch 408.

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

The RJ-45 ports (10 Mbps and 100 Mbps) on the Switch 408 have the

HP Auto-MDIX feature, which allows you to use either “straightthrough” or “crossover” twisted-pair cables for connections to any other network device that has RJ-45 connectors.

These additional rules apply to the twisted-pair cabling:

■ All twisted-pair wires used must be twisted through the entire length of the cable. The wiring sequence must conform to the

ANSI/TIA/EIA-568-B cable specification. See “Twisted-Pair Cable

Pin Assignments” later in this appendix for a listing of the signals used on each pin.
