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
•
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.
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.

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.
Continued on the next page.

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”.

■
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:

category 3, 4, or 5 - 100 meters
Note: Since the 10Base-T operation is through 10/100Base-TX ports, if you ever want to upgrade the ports to
100Base-T, it would be best to cable the ports initially with category 5 cable.
100 meters
■
Installation Location
- Before installing the switch, plan its location and orientation relative to other devices and equipment.
At the front of the switch, leave at least 7.6 cm (3 inches) of space for the twisted-pair cabling. At the back of the switch, leave at least 2.6 cm (1 inch) of space for the adapter’s power cord.

Installation Procedures
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.

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

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.

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.
Check in the table for the LED pattern that you see on your switch.

Diagnostic Tips:
Tip
Number Problem
➊
The switch’s power adapter is not plugged into an active
AC power source, or the power adapter may have failed.
➋
A switch hardware failure was detected during self test.
➌
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.

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.

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.
