Throughout this manual, this switch will be abbreviated as the Switch 1600M.
The Switch 1600M has 16 10/100Base-T RJ-45 ports, and a slot for installing
any of the supported switch modules. At the time of this printing, there are 4:
With this switch you can build a switched network infrastructure by
connecting it to hubs, other switches, or routers, or you can connect
computers, printers, and servers to these switches to provide dedicated
bandwidth to those devices.
This chapter describes your HP Switch 1600M including:
This port is used to connect a console to the switch by using the serial cable
supplied with the switch. This connection is described under “Connecting a
Console to the Switch” in chapter 2, “Installing the Switch 1600M”. The console
can be a PC running a VT-100 terminal emulator, or a VT-100 terminal.
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.
■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.
■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 8,
“Troubleshooting” of the HP Switch 8000M and 1600M Management and Configuration Guide that came with your switch.

The Switch 1600M 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.

Trunking, and IGMP.
Address Learning. As devices are connected to the switch ports, either
directly or through hubs or other switches that are connected to the switch,
Introducing the HP Switch
the MAC addresses of those devices are learned automatically and stored in
the Switch 1600M’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.
■flood - whenever a new destination address is found in a packet, the
destination address will not yet be in the switch’s address table and the
Switch1600M cannot know whether to forward or filter out the packet. In
this case, it sends the packet to all the 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 1600M 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.
In addition to traffic isolation benefits provided by the Switch 1600M 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.
For more information on configuring VLANs and their behavior, see the HP ProCurve Switch 8000M and 1600M Management and Configuration Guide
that came with your switch.
The HP Switch 1600M is an easy to install unit. It comes with an accessory kit
that includes the brackets for mounting the switch in a standard 19-inch telco
rack or an equipment cabinet, or on a wall, and with rubber feet that can be
attached so the switch can be securely located on a horizontal surface. The
brackets are designed to allow mounting the switch in a variety of orientations.
This chapter shows you how to install your Switch 1600M.

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 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.(Optional) Install switch module. The Switch 1600M has a slot for
installing any of the supported HP Switch port modules. Depending on
where you will install the Switch 1600M, it may be easier to install the
module first, but the modules are “hot swappable”—they can also be
installed and removed after the switch is installed and powered on.
Installing the Switch 1600M
3.Verify that the switch passes 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 and on the modules show correct operation.
4.Mount the switch. The Switch 1600M can be mounted in a 19-inch telco
rack, in an equipment cabinet, on a wall, or on a horizontal surface.
5.Connect power to the switch. Once the switch is mounted, plug it in
to the nearby main power source.
6.Connect the network devices. Using the appropriate network cables,
connect other switches, hubs, routers, computers, servers, printers, and
other network devices to the switch ports.
7.(Optional) Connect a console to the switch for configuration. In
the factory default configuration, the Switch 1600M operates, without any
changes, as a multiport transparent bridge. 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 using the included
console cable to connect a PC to the switch’s console port.
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.
Follow these precautions when installing your HP Switch 1600M.

Installation Summary
Warning
Cautions
■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 1600M
■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 if no module is installed in the module slot, the cover plate
is installed to cover the slot. A cover plate is required for safe operation,
and to ensure proper switch cooling.
■Cabling Infrastructure - Ensure that the cabling infrastructure meets
the necessary network specifications. See the following table for cable
types and lengths, and see appendix B, “Cables and Connectors” for more
information:

Installation Summary
Notes
Any of the supported switch modules can be installed in the slot.
■
■The module can be “hot swapped”, installed when the switch is powered
on and normally will be immediately operational. But, if the module is
replacing a module of a different type that was previously installed in the
slot, the switch must be rebooted after the module is installed. See “Hot
Swapping the Switch Port Module” on page 2-15.
■Make sure the module is fully installed and that you screw in the
retaining screws to secure the module in place.
■If you do not install a module in the slot, make sure that the slot cover
plate is still attached over the slot for safe operation and proper switch
cooling.
Insert module into the guides and slide i t
in until it stops. Then press in firmly until
the module “snaps” into place and is
flush with the face of the switch.
make sure you tighten the retaining
screws on the module
After you have installed a switch port module, 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.
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
Installing the Switch 1600M
Connect power cord to
the power connector
The Switch 1600M does not have a power switch. It is 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 and on the switch module (if installed). The
LED behavior is described on the next page.
When the switch is powered on, it performs its diagnostic self test. The
self test takes approximately 30 to 45 seconds to complete, depending on
whether a switch port module is installed in the slot.
LED Behavior:
During the self test:
•Initially, all the switch and port 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 if a switch port module is installed
in the slot, the Module Status LED stays on, and the Fan Status LED
stays on.
•The large Fault LED and Self Test LED go off.
•The port LEDs near the network ports and on the switch port module
go into their normal operational mode, if they are connected to active
network devices.
Installing the Switch 1600M
If the LED display is different than what is described above, especially if
the Fault and Self Test LEDs stay on for more than 60 seconds or they
start flashing, the self test has not completed correctly. Refer to chapter
3, “Troubleshooting” for diagnostic help.
After a module is inserted and you have verified that the switch passes self
test, you are ready to mount the switch in a stable location. The Switch 1600M
can be mounted in these ways:
■in a rack or cabinet
■on a horizontal surface
■on a wall
Rack or Cabinet Mounting
The Switch 1600M is designed to be mounted in any EIA-standard 19-inch telco
rack or in an equipment cabinet such as a server cabinet.

Connecting Cables to the Switch Port Module
If you have a switch port module installed in the switch, the type of network
connections you will need to use depends on the type of module you have
installed. See the documentation accompanying the modules for cabling
configurations and procedures for those modules.
The module documentation will also cover troubleshooting procedures for
connections to the module, but, in general for all the switch ports, when a
network cable from an active network device is connected to the 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, see “Diagnosing With the LEDs” in
chapter 3, “Troubleshooting”.
The Switch 1600M has 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 console, web browser interface, and
■
network management access to the switch
The console can be accessed through these methods:
■
Out-of-band: The Switch 1600M comes 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 “straightthrough” 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.
Installing the Switch 1600M
Installation Summary
Installing the Switch 1600M
The Switch 1600M can simultaneously support one console session through
the Console Port and one Telnet console session.
Terminal Configuration
To connect a console to the switch, configure the PC terminal emulator as a
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 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 with settings on both the terminal and on the switch. Change the
switch settings first, then change the terminal settings, and reestablish the
console session.
To connect a console to the
switch, follow these steps:
1.Connect the PC or

The switch port module can be “hot swapped”, that is installed or replaced
while the switch is powered on. The procedures differ slightly, though
between adding a new module to the empty slot or replacing the module with
the same type, and exchanging the module with a different type.
Adding or Replacing the Module
Installing the Switch 1600M
If a module has to be replaced with one of the same type, or you are expanding
the switch capability by adding a module when 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 the module with one of a different type though, for example
a 100Base-FX module is installed in place of a 10/100Base-T 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.
Your switch is now correctly installed and is able to send and receive data
between end nodes, servers, and printers.
The Switch 1600M is a plug-and-communicate network device requiring no
configuration. If you wish to manage the switch from an SNMP-based network
management station, you will need to configure the IP address on the switch;
see the HP Switch 8000M and 1600M Management and Configuration Guide that came with your switch for information on how to use the switch
console interface to configure the IP address.
This chapter describes how to troubleshoot your Switch 1600M. Note that this
document describes troubleshooting mostly from a hardware perspective.
You can perform more in-depth troubleshooting using the software tools
available with the switch, including the full-featured console interface, the
built-in web browser interface, and HP TopTools for Hubs & Switches, the
SNMP-based network management tool. See the Troubleshooting chapter of
the HP ProCurve Switch 8000M and 1600M Management and Configuration Guide included with your switch for more information.

Troubleshooting
If you
.
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
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
[Technology] button.
Troubleshooting
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 console, the web agent interface, or HP TopTools for Hubs & Switches.
The Switch 1600M also supports Switch Meshing which allows multiple
data paths though a switched network to be active simultaneously for
enhanced network bandwidth. See the HP ProCurve Switch 8000M and 1600M Management and Configuration Guide for more information on
Spanning Tree and on Switch Meshing.
The switch is not

1. Verify that the power cord is plugged into an active power source and to the
switch. Make sure these connections are snug.
2. T ry 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.
If necessary to resolve the problem, contact 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.
Troubleshooting

The module
installed in the slot
is not installed
properly, has
experienced a self
test fault, or has
become partly
removed during
switch operation.
The module is 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 it is 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
information.
A module was
installed in the slot
that is a different
type than the
previously installed
module, and the
switch has not yet
been reset.
One or more of the
switch cooling fans
may have failed.
The network
connection is not
working properly.
When you “hot swap” modules in the switch slot, 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
• power cycling the switch
• selecting the reset or reboot option from the console, web browser interface, or
HP TopTools.
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,
one or more of the fans has failed. The switch has two fans and may continue to
operate OK under this condition if the ambient temperature does not exceed normal
room temperature, but for best operation, the switch should be replaced. Contact
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 snug.
on
• 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.
and operating
Troubleshooting
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.
The Switch 1600M has 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
Troubleshooting
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.
See chapter 8, “Troubleshooting”, in the HP ProCurve Switch 8000M and 1600M Management and Configuration Guide that came with your switch
for more information on using these software tools to diagnose and manage
your switch.
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
Hardware Diagnostic Tests
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 45 seconds depending on whether a module
is installed in the switch. If these LEDs stay on longer than 60 seconds or begin
flashing, the switch may have to be replaced.
See “Diagnosing With the LEDs” on page 3-3 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”,
Connect a PC running a VT-100 terminal emulator program or a standard VT100 terminal to the switch’s Console Port and configure it with the terminal
communication settings shown on page 2-13. Then, when you reset the switch,
note the messages that are displayed.
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 1600M 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
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
■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 HP ProCurve Switch 8000M and 1600M 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.
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.
HP Customer Support Services
Troubleshooting
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/network_city also provides up-to-date support information.
Additionally, your HP-authorized network reseller can also provide you with
assistance, both with services that they offer and with services offered by HP.
This appendix includes minimum pin-out information and specifications for
cables that should be used with the Switch 1600M.
NoteIncorrectly 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.

Cables and Connectors
Twisted-Pair Cable/Connector Pin-Outs
The RJ-45 ports (10 Mbps and 100 Mbps) on the Switch 1600M 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 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.
