Reset Button

This button is used to reset the switch while it is powered on. This action clears
any temporary error conditions that may have occurred, executes the switch
self test, and resets all network activity counters to zero. The counters are
displayed in the switch console interface, the switch web browser interface,
and through SNMP network management applications, such as HP TopTools
for Hubs & Switches.

Clear Button

This button is used for these purposes:

■ Deleting Passwords - When pressed by itself for at least one second,

deletes any switch console access passwords that you may have config­ured. Use this feature if you have misplaced the password and need
console access.

This button is provided for your convenience, but its presence means
that if you are concerned with the security of the switch configuration
and operation, you should make sure the switch is installed in a secure
location, such as a locked wiring closet.

Introducing the HP ProCurve

Switch 4000M and 8000M

■ Restoring Factory Default Configuration - When pressed with the

Reset button in a specific pattern, clears any configuration changes you
may have made through the switch console, the web browser interface,
and SNMP management, and restores the factory default configuration to
the switch. For the specific method to restore the factory default config­uration, see “Restoring the Factory Default Configuration” in chapter 3,
“Troubleshooting” of this manual.

Caution

AC power connector

slot for installing optional
redundant power supply

Power Connector

The Switch 4000M and 8000M does not have a power switch; it is powered on
when connected to an active AC power source. The switch automatically
adjusts to any voltage between 100-127 and 200-240 volts and either 50 or 60
Hz. There are no voltage range settings required.

Slot for Redundant Power Supply

A second, load-sharing redundant power supply (HP ProCurve Switch 4000M/
8000M Power Supply, HP J4119A) can be installed in the back of the switch.
To provide true redundancy, this second power supply should be connected
to a different AC power source from the other supply. Then, if one AC power
source fails, the switch will continue to run.

The switch power supplies are hot swappable, but,
as indicated by the caution statement on the power
supply, it must be disconnected from AC power
before being installed or removed.

Because the switch can run on a single supply, removing a redundant supply
will not interrupt switch operation.

Switch Operation Overview

Switch Operation Overview

Address Table Operation

Address Learning. As devices are connected to the switch ports, either
directly or through hubs or other switches that are connected to the switch,

Switch 4000M and 8000M

Introducing the HP ProCurve

the MAC addresses of those devices are learned automatically and stored in
the Switch 8000M’s 8000-entry address table. The switch also identifies the
number of the port on which each address is learned so it knows the network
location of each device.

Forwarding, Filtering, Flooding. When the switch receives a packet, it
determines the destination address, 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 lose bandwidth dealing with unnecessary traffic. (You can
also configure filters on the switch that filter out packets based on specific
criteria.)

■ flood - whenever a new destination address is found in a received packet,

the destination address will not yet be in the switch’s address table and
the Switch 8000M cannot know whether to forward or filter out the
packet. In this case, it sends the packet out all the ports other than the
one on which it was received. 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.

Introducing the HP ProCurve Switch 4000M and 8000M

Switch Operation Overview

Network Moves and Changes. When devices are moved in the network,
and become connected to a different switch port, the Switch 4000M and 8000M
automatically recognizes the change and updates the address table with the
new port location of the device. Communication with the device is automati­cally maintained, without any address table manipulation being required.

Simultaneous Network Communications

In addition to traffic isolation benefits provided by the Switch 4000M and
8000M address table operation, the switch also enhances network perfor­mance because it can conduct multiple, simultaneous network connections.
Instead of sharing the network bandwidth, as in connections to a hub, each
connection has its own 10 Mbps, 100 Mbps, or 1000 Mbps bandwidth to use.

Effect of VLANs

If you configure multiple virtual LANs (VLANs) on the switch, each VLAN
behaves as a “logical switch” containing the switch ports that you assign to it.
Each logical switch behaves as an isolated broadcast domain, just as if it were
a separate physical switch. The forward, filter, and flood behavior described
for the physical switch above, operates the same for each of the logical
switches defined by the VLANs: packets are forwarded or flooded only to the
ports that are within a given VLAN. Just as for separate physical switches,
there is no communication between ports that are in separate VLANs unless
the VLANs are connected by an external router.

Switch 4000M and 8000M

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 (page 2-4). Make sure that the physical

environment into which you will be installing the switch is properly
prepared including having the correct network cabling ready to connect
to the switch, and having a good location for the switch. Please see page

2-3 for some installation precautions.

2. Install switch modules (page 2-5). The Switch 4000M and the Switch

8000M have ten universal slots for installing any of the HP ProCurve
switch modules. The Switch 4000M has five 10/100Base-T modules pre­installed. Depending on where you will install the Switch 4000M and

and 8000M

Installing the Switch 4000M

8000M, it may be easier to install the modules first, but the modules are
“hot swappable”—they can also be installed and removed after the switch
is powered on.

3. (Optional) Install second power supply (page 2-6). The Switch

4000M and 8000M have a slot in the back for installing a second, load­sharing power supply. If you have purchased this supply, it may be easier
to install it before mounting the switch, although the power supplies are
“hot swappable”—they can be installed and removed after the switch
powered on.

2-2

4. Verify that the switch passes self test (page 2-8). This is a simple

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

5. Mount the switch (page 2-10). The Switch 4000M and 8000M can be

mounted in a 19-inch telco rack, in an equipment cabinet, on a wall, or on
a horizontal surface.

6. Connect power to the switch (page 2-14). Once the switch is mounted,

plug it in to the nearby main power source.

7. Connect the network devices (page 2-14). Using the appropriate

network cables, connect other switches, hubs, routers, computers,
servers, printers, and other network devices to the switch ports.

4080~1.boo : 4080_2.FM Page 3 Thursday, July 2, 1998 1:43 PM

8. (Optional) Connect a console to the switch (page 2-15). You may

wish to modify the switch’s configuration, for example, to configure an IP
address so it can be managed using a web browser or from an SNMP
network management station. Configuration changes can be made easily
by through the switch’s console interface.

At this point, the switch is fully installed. See the rest of this chapter if you
need more detailed information on any of these installation steps.

Installation Precautions

Installing the Switch 4000M and 8000M

Installation Procedures

Warning

Cautions

Follow these precautions when installing your HP Switch 4000M and 8000M

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.

■ Make sure that the power source circuits are properly grounded, then

use the power cord supplied with the switch to connect it to the power
source.

If your installation requires a different power cord than the one supplied
with the switch, 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 switch.

■ Ensure 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 ampere 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 ampere ratings are usually printed on
the devices near the AC power 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 and back of the switch is not

■

restricted.

■ Make sure that for any switch slot into which no module is installed, the

cover plate is installed to cover the slot. A cover plate is required for safe
operation, and to ensure proper switch cooling.

■ The modules can be “hot swapped”, installed when the switch is powered

on, and normally will be immediately operational. But, if you are replacing
a module with a different type than what was previously installed in the
slot, the switch must be rebooted after the module is installed. See “Hot
Swapping the Switch Module” on page 2-17.

■ Make sure the module is fully installed and that you screw in the

retaining screws to secure the module in place.

3. (Optional) Install Second Power Supply

A second, load-sharing redundant power supply (HP ProCurve Switch 4000M/
8000M Power Supply, HP J4119A) can be installed in the back of the switch.
To provide true redundancy, this second power supply should be connected
to a different AC power source from the other supply. Then, if one AC power
source fails, the switch will continue to run. Each supply provides enough
power to operate a fully loaded switch, so even if one fails, the switch will
continue to operate normally.

Install the second power supply into power slot number 2 as shown in the
illustration on the next page.

The slot cover can be removed with either a flat-bladed or Torx T-10 screw­driver. Retain the slot cover for future use.

4. Verify the Switch Passes Self Test

After you have installed any modules and the optional second power supply,
but before mounting the switch 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.

If you have installed a second power supply, repeat these procedures with the
second power supply to verify that it works correctly too.

1. Connect the power cord supplied with the switch to the power connector
on the back of the switch, and then into a properly grounded electrical
outlet.

Note

Connect power cord to
power connector

The Switch 4000M and 8000M do not have a power switch. They are powered
on when the power cord is connected to the switch and to a power source.

If your installation requires a different power cord than the one supplied with
the switch, 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 switch.

2. Check the LEDs on the Switch Engine Module and on each of the switch
modules. The LED behavior is described on the next page.

If the LED display is different than what is described, especially if any
Fault LEDs stay on for more than approximately 80 seconds or they start
flashing, the self test has not completed correctly. Refer to chapter 3,
“Troubleshooting” for diagnostic help.

LED Behavior:

During the self test:

• Initially, Power and Fault, and all the Switch Engine and switch

module LEDs are on.

• After approximately 3 seconds most of the LEDs go off and then may

come on again during phases of the self test. For the duration of the
self test, the Self Test LED stays on.

When the self test completes successfully:

• The large Power LED stays on, and the Status LEDs on the Switch

Engine Module stay on for the modules installed: one for each switch
module installed, one for each power supply installed, and the Fan
LED.

• The large Fault LED goes off, and the Switch Engine Fail and

Self Test LEDs go off.

• The port LEDs on the switch modules go into their normal operational

mode:
– If the ports are connected to active network devices, the Link

LEDs stay on and the Mode LEDs behave according to the mode
selected. In the default mode (Activity), the Mode LEDs should
flicker showing network activity on the port.

– If the ports are not connected to active network devices, the LEDs

will stay off.

6. Connect the Switch to a Power Source

1. Plug the included power cord into the switch’s power connector and into
a nearby properly grounded AC power source.

If you have installed a redundant power supply module into the switch, it
should be connected to a separate AC power source. Then, if there is a
power outage from one of the AC sources, the switch will continue to
operate by power coming from the other source.

See the HP ProCurve Switch 4000M/8000M Power Supply Installation
Guide for additional information.

2. Re-check the LEDs during self test. See “LED Behavior” on page 2-9.

and 8000M

Installing the Switch 4000M

7. Connect the Network Devices

The type of network connections you will need to use depends on the types
of switch modules you have installed in your Switch 4000M and 8000M. See
the documentation accompanying the modules for cabling configurations and
procedures for those modules.

The module documentation will also cover troubleshooting procedures, but,
in general for all the modules, when a network cable from an active network
device is connected to the switch module port, the Link LED for that port
should go on. If the Link LED does not go on when the network cable is
connected to the port, use the table below to help solve the problem.

Condition Diagnostic Tip

Port LED is
still off when
a cable is
connected

Try the following procedures:

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

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

• Verify that you have used the correct cable type for the connection.

- for twisted-pair connections, in general, for connecting to an end node, use “straight­ through” cable; for connecting to hubs or other switches, use “crossover” cable.

- for fiber-optic connections, verify that the transmit port on the switch is connected to
the receive port on the connected device, and the switch receive port is connected to
the transmit port on the connected device.

• Verify that the port has not been disabled through a switch configuration change.
You can use the console interface, or, if you have configured an IP address on the switch,

use the web browser interface, or HP TopTools for Hubs & Switches network management
software to determine the state of the port and re-enable the port if necessary.

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

8. (Optional) Connect a Console to the Switch

The Switch 4000M and 8000M have a full-featured, easy to use console
interface for performing the following tasks:

■ Monitor switch and port status and observe network activity counters

■ Modify the switch’s configuration

■ Read the event log and access diagnostic tools to help in troubleshooting

■ Download new software to the switch

Add passwords to control access to the switch from the console, web

■

browser interface, and network management stations

The console can be accessed through these methods:

■

Out-of-band: The Switch 4000M and 8000M come with a serial cable for
connecting a PC or VT-100 terminal to be used as a console directly to the
switch. If the PC or terminal has a 25-pin serial connector, you can use a
readily available 9-pin to 25-pin serial cable, or attach a 9-to-25 pin
“straight-through” adapter to the end of the supplied cable.

■ In-Band: Access the console using telnet from a PC or UNIX station on

the network, and a VT-100 terminal emulator. This method requires that
you first configure the switch with an IP address and subnet mask by using
either out-of-band console access or through DHCP/Bootp.

Installation Procedures

Installing the Switch 4000M

and 8000M

The Switch 4000M and 8000M can simultaneously support one out-of-band
console session through the Console Port and one in-band telnet console
session.

Terminal Configuration

To connect a console to the switch, configure the PC terminal emulator as a
VT-100 or DEC VT-100 (ANSI) terminal, or use a VT-100 terminal and configure
it to operate with these settings:

• any baud rate from 2400 to 115200 (the switch automatically senses
the speed)

• 8 data bits, 1 stop bit, no parity, XON/XOFF flow control

• For Windows Terminal program, also disable (uncheck) the “Use
Function, Arrow, and Ctrl

If you want to operate the console using a different configuration, make sure
you change the settings on both the terminal and on the switch. Change the
switch settings first, then change the terminal settings, and reestablish the
console session.

Installing the Switch 4000M and 8000M

Hot Swapping Switch Modules

The switch modules can be “hot swapped”, that is installed or replaced while
the switch is powered on. The procedures differ slightly, though between
adding new modules to an empty slot or replacing modules with the same type,
and exchanging the module with a different type.

Adding or Replacing Modules

Hot Swapping Switch Modules

If a module has to be replaced with one of the same type, or you are expanding
the switch capability by adding a module in a slot where one was not previ­ously installed, the replaced or new module is immediately operational; there
is no interruption to the switch operation.

Changing the Module Type

If you exchange a module with one of a different type though, for example a
Gigabit-SX module is installed in place of a 100Base-FX module that was in
the slot, the switch must be rebooted after the new module is installed so the
switch processor can properly initialize and configure the new module type.

You can reboot the switch by any of these methods:

■ select the Reset or Reboot option from the console, web browser inter-

face, or HP TopTools for Hubs & Switches

■ press the Reset button on the switch

■ unplug and plug in the power cord (power cycle)

Until the switch is rebooted, the module will not operate, the Module Status
LED will continue to flash, and all the LEDs on the module will stay on
continuously.

Basic Troubleshooting Tips

Basic Troubleshooting Tips

Most problems are caused by the following situations. Check for these items
first when starting your troubleshooting:

■ Incorrect switch-to-switch or switch-to-hub connections. If you

have connected your switch to another switch or a hub by using twisted­pair cable from an RJ-45 MDI-X connector on your switch to the an MDI­X connector on the other switch or hub, you must use a crossover cable.
If you have used a straight-through cable, the connection will not work.
The LED for the port you are using will not come on when you connect
the cable.

Troubleshooting

Most switch and hub ports are wired as MDI-X ports, so for these switch­to-switch or switch-to-hub connections use a crossover cable. LAN
adapters in end nodes are normally wired as MDI ports as are some ports
on hubs and switches. For connections from the switch to these MDI
ports, use a straight-through cable. See appendix B, “Cables and
Connectors” for pinouts and correct cable wiring for crossover and
straight-through twisted-pair cables.

■ Faulty or loose cables. Look for loose or obviously faulty connections.

If they appear to be OK, make sure the connections are snug. 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 excessive repeater delays 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/network_city under the

[Tech Library] button.

3-2

4080~1.boo : 4080_3.FM Page 3 Thursday, July 2, 1998 1:43 PM

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.

If you wish to build redundant paths between important nodes in your
network to provide some fault tolerance, you should enable Spanning
Tree Protocol support on the switch. This ensures that only one of the
redundant paths is active at any time, thus avoiding data path loops.
Spanning Tree can be enabled through the switch console, the web
browser interface, or HP TopTools for Hubs and Switches.

The Switch 8000M also supports Switch Meshing which allows multiple
data paths though a switched network to be active simultaneously for
enhanced network bandwidth. See the Management and Configuration
Guide that came with your switch for more information on Spanning Tree
and on Switch Meshing.

The power supplies
installed in the
switch are not
plugged into active
AC power sources,
or the power supply
may have failed.

A switch hardware
failure has
occurred. All the
LEDs will stay on
indefinitely.

The switch has
experienced a
software failure
during self test.

1. Verify that the power cord 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 the power cord back in.

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 or
try a different power cord.

If the power source and power cord are OK and this condition persists, the switch
power supply 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 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.

1. Try resetting the switch by pressing the Reset button on the front of the switch,
or by power cycling the switch.

2. If the fault indication reoccurs, attach a console to the switch (as indicated in
chapter 2) and configure it to operate at 9600 baud. Then, reset the switch.
Messages should appear on the console screen and in the console log identifying
the error condition. You can view the console log at that point by selecting it from
the console Main Menu.

The module
installed in the slot
that corresponds to
the letter that is
flashing is not
installed properly,
has experienced a
self test fault, or has
become partly
removed during
switch operation.

The modules are all tested whenever the switch is powered on, or reset (through
the Reset button on the switch, or the Reboot or Reset options in the console or web
browser interface), and when they are hot swapped (installed when the switch is
powered on).

Under this error condition, the following events also occur:

• All the LEDs on the module stay on until the error is resolved.

• The switch software, including console and web browser access will not be
operational for approximately one minute from the time the module gets into this
condition.

T ry reinstalling the module. You can do this without having to power down the switch.
When the module is reinstalled, it will be retested automatically. Make sure to screw
in the retaining screws so that the module cannot be inadvertently pulled out by
pulling on the network cables.

If the fault indication reoccurs, the module may have failed. Remove the module from
the switch and replace it with another module, or recover the slot with the cover
plate. 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

may have failed.

When you “hot swap” modules in the switch slots, if you install a different module
type than the one that was previously installed in the slot, you must reset the switch
so the switch processor can properly initialize and configure the new module type.
The flashing LED informs you that this change of module types has occurred. The
module will not work properly until the switch is reset as indicated by all the module’s
LEDs staying on until the switch is reset.

You can reset the switch by any of these methods:

• pressing the Reset button on the Switch Engine Module

• power cycling the switch

• selecting the reset or reboot option from the console, web browser interface, or
HP TopTools.

Try removing and reinstalling the supply.

Caution: Make sure that the AC power cord is disconnected from the supply before
removing and reinstalling the supply.

Reconnect the power supply to the AC power source. If the error indication reoccurs
after the supply is reinstalled, the power supply may be faulty. Call your HP­authorized LAN dealer, or use the electronic support services from HP to get
assistance. See the Customer Support/Warranty card for more information.

T ry disconnecting power from the switch and wait a few moments. Then reconnect
the power to the switch and check the LEDs again. If the error indication reoccurs,

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

• Verify that you have used the correct cable type for the connection.

- for twisted-pair connections, in general, for connecting to an end node, use
“straight- through” cable; for connecting to MDI-X ports on hubs or other
switches, use “crossover” cable.

- for fiber-optic connections, verify that the transmit port on the switch is con­nected to the receive port on the connected device, and the switch receive port
is connected to the transmit port on the connected device.

• Verify that the port has not been disabled through a switch configuration change.
You can use the console interface, or, if you have configured an IP address on

the switch, use the web browser interface, or HP TopTools for Hubs & Switches

Proactive Networking

The Switch 4000M and 8000M have built-in management capabilities that
proactively help you manage your network including:

■ finding and helping you fix the most common network error conditions (for

example, faulty network cabling, and non-standard network topologies)
informing you of the problem with clear, easy-to-understand messages

■

■ recommending network configuration changes to enhance the perfor-

mance of your network

The following interfaces provide tests, indicators, and an event log that can
be used to monitor the switch and its network connections and to help you
take advantage of these proactive networking features:

■ HP TopTools for Hubs & Switches - an SNMP-based network management

tool that is included with your switch

■ A graphical web browser interface that you can use to manage your switch

from a PC running a supported web browser, for example Microsoft
Internet Explorer, and Netscape Communicator.

■ A full-featured easy-to-use console interface that you can access by

merely connecting a standard terminal or PC running a terminal emulator
to the switch’s console port. The cable to make that connection is
provided with your switch. The console interface is also accessible
through a telnet connection.

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 and operating code. To reset a switch, either:

■ Unplug and plug in the power cord (power cycling)

■ Press the Reset button on the front of the switch

Power cycling the switch and pressing the Reset button both cause the switch
to perform its power-on self-test, which almost always will resolve any tempo­rary operational problems. These reset processes also cause any network
traffic counters to be reset to zero, and cause the System Up Time timer to
reset to zero. None of the reset procedures cause any changes to the switch
configuration.

Troubleshooting

Checking the Switch LEDs

The self-test passes if the Fault and Self Test LEDs on the front of the switch
go off after approximately 30 to 70 seconds depending on the number and type
of modules installed in the switch. If these LEDs stay on longer than 80 seconds
or begin flashing, the switch may have to be replaced.

See “Diagnosing With the LEDs” on page 3-4 for information on interpreting
the LED patterns.

Checking Console Messages

Useful diagnostic messages may be displayed on the console screen when the
switch is reset. As described in chapter 2 under step 8, “Connect a Console to
the Switch”, connect a PC running a VT-100 terminal emulator program or a
standard VT-100 terminal to the switch’s Console Port and configure it to run
at 9600 baud, and with the other terminal communication settings shown on
page 2-15. Then, when you reset the switch, note the messages that are
displayed.

4080~1.boo : 4080_3.FM Page 9 Thursday, July 2, 1998 1:43 PM

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-T standards. The
twisted-pair cables attached to the Switch 4000M and 8000M 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

Hardware Diagnostic Tests

Note

Make sure that you are using the correct cabling type for each connection.
The switch UTP ports are all wired as MDI-X. For connecting end nodes and
other MDI-type devices, use “straight-through” cable. For connecting hubs,
other switches, and other MDI-X devices, use “crossover” cable. See appendix
B, “Cables and Connectors” for the pinouts for these cables.

Testing Switch-to-Device Network Communications

You can perform the following communication tests to verify that the network
is operating correctly between the switch and any connected device that can
respond correctly to the communication test.

■ Link Test -- a physical layer test that sends IEEE 802.2 test packets to any

device identified by its MAC address

Troubleshooting

■ Ping Test -- a network layer test used on IP networks that sends test

packets to any device identified by its IP address

These tests can be performed through the switch console interface from a
terminal connected to the switch or through a telnet connection, or from the
switch’s web browser interface. See the Management and Configuration
Guide that came with your switch for more information.

These tests can also be performed from an SNMP network management
station running a program that can manage the switch, for example, HP
TopTools for Hubs & Switches.

Troubleshooting

Restoring the Factory Default Configuration

Testing End-to-End Network Communications

Both the switch and the cabling can be tested by running an end-to-end
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 that have LAN adapters between which you can run a link-level test
or Ping test through the switch, you can use this 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 the a link test
or Ping test.

Restoring the Factory Default

Troubleshooting

Configuration

As part of your troubleshooting process, it may become necessary to return
the switch configuration to the factory default settings. This process momen­tarily interrupts the switch operation, clears any passwords, clears the console
event log, resets the network counters to zero, performs a complete self test,
and reboots the switch into its factory default configuration including deleting
an IP address.

To execute the factory default reset, perform these steps:

1. Using pointed objects, simultaneously press both the Reset and Clear
buttons on the front of the switch.

2. Continue to press the Clear button while releasing the Reset button.

3. When the Self Test LED begins to flash, release the Clear button.
The switch will then complete its self test and begin operating with the

configuration restored to the factory default settings.

Cables and Connectors

Twisted-Pair Cable/Connector Pin-Outs

The RJ-45 ports on the 10/100Base-TX Switch Module are wired as MDI-X
ports. The type of twisted-pair cable you connect to these ports (either
“straight through” or “crossover”) depends on the type of device at the other
end of the cable.

The rule is, when connecting same-type ports together (for example MDI­X-to-MDI-X), use crossover cable; when connecting opposite-type ports
together (for example MDI-X-to-MDI), use straight-through cable.

These additional rules apply:

■ All twisted-pair wires used must be twisted through the entire length of

the cable. The wiring sequence must conform to EIA/TIA 568B or AT&T
258A (not USOC). See “Twisted-Pair Cable Pin Assignments” later in this
appendix for a listing of the signals used on each pin.

For connections to the 10 Mbps ports, you can use Category 3, 4, or 5

■

unshielded twisted-pair cable, as supported by the IEEE 802.3 Type
10Base-T standard.

■ For connections to the 100 Mbps ports, use 100-ohm Category 5 UTP or

STP cable only, as supported by the IEEE 802.3u Type 100Base-TX stan­dard.

Statements

CAUTION A CAUTION in the manual denotes a hazard that can damage

equipment.
Do not proceed beyond a WARNING or CAUTION notice until you

have understood the hazardous conditions and have taken appro­priate steps.

Grounding

These are safety class I products and have protective earthing terminals. There
must be an uninterruptible safety earth ground from the main power source
to the product's input wiring terminals, power cord, or supplied power cord
set. Whenever it is likely that the protection has been impaired, disconnect
the power cord until the ground has been restored.

For LAN cable grounding:

■ If your LAN covers an area served by more than one power distribu-

tion system, be sure their safety grounds are securely interconnected.

■ LAN cables may occasionally be subject to hazardous transient volt-

ages (such as lightning or disturbances in the electrical utilities power
grid). Handle exposed metal components of the network with caution.

Servicing

There are no user-serviceable parts inside these products. Any servicing,
adjustment, maintenance, or repair must be performed only by service-trained
personnel.

These products do not have a power switch; they are powered on when the
power cord is plugged in.
