device.

Off One of these conditions exists:

• no active network cable is connected to the port

• the port is not receiving link beat or sufficient light

• the port has been disabled through the switch console, the web browser
interface, ProCurve Manager

, or other network management tool.

Blinking

The port has failed self test. The switch Fault, Self Test LEDs, and appropriate
module status LEDs will flash simultaneously.

Mode Depending on the mode selected, displays the following: network activity information, whether

the port is configured for Full Duplex operation, maximum speed operation, or whether PoE
power is being supplied or not. See “LED Mode Select Button and Indicator LEDs” below for
more information.

The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.

LED Mode Select Button and Indicator LEDs

To optimize the amount of information that can be displayed for each of the
switch ports, the 5400 zl switches use a Mode LED for each port. The operation
of this LED is controlled by the LED Mode Select button on the switch chassis,
and the current selection is indicated by the mode indicator LEDs near the
button. Press the button to change from one mode to the next.

Console Port

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 5400 zl Switches”. The
console is a full-featured interface that can be used to configure, monitor, and
troubleshoot the switch. It can be run on a PC, laptop, or handheld device
emulating a VT-100 terminal, or on a standard VT-100 terminal.

Reset Button

This button will reset the switch when 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 ProCurve
Manager.

Press the Reset button also after changing the module type that is installed in
any of the switch module slots while the switch is powered on. In this case,
the switch must be reset to initialize the new module type. See “Hot Swapping
Switch Modules” on page 2-26.

Clear Button

This button is used for the following purposes:

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

Clear button 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, the Clear button clears any configura­tion changes you may have made through the switch console, the web
browser interface, or 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 4, “Troubleshooting” of this manual.

The Series 5400 zl Switches do not have a power switch; they are powered on
when connected to an active AC power source. The 5400 zl switches automat­ically adjust to any voltage between 100-127 and 200-240 volts when using the
J8712A power supply, 200-240 volts when using the J8713A power supply, and
110-127 and 200-240 volts when using the J9306A power supply, and either 50
or 60 Hz. There are no voltage range settings required.

Redundant Power Supply

Load-sharing redundant power supplies (HP Switch zl 875 W Power Supply,
J8712A, a Switch zl 1500 W Power Supply J8713A, or a Switch zl 1500 W PoE+
Power Supply J9306A) can be installed in the back of the 5400 zl switches. To
provide redundancy, each power supply should be connected to different AC
power sources. Then, if one AC power source fails, the switch will continue
to run.

Note The J8712A and J8713A power supplies can be paired within the same switch

or within the Power Supply Shelf. However,the J9306A power supply can only
be paired with another J9306A power supply within the same switch or within
the Power Supply Shelf. The J9306A power supply cannot be used with either
the J8712A or J8713A power supplies.

Caution The switch redundant power supply is 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.

CAUTION:

.
.

Disconnect AC power from the power supply BEFORE installing or
removing the supply. Otherwise, damage to the equipment may result.

.

Refer to the installation guide for proper power cord selection

Because the switch can run on a single supply, removing a redundant supply
will not interrupt switch operation. However,on the 5412 zl one power supply
will only supply enough power to run the module slots A-F. Slots G-L will not
receive any power unless there are at least two power supplies installed.

When power is restored from a second (or more) power supplies, a system
reload or interface module reset is required to restore operation to slots G-L.
To reset the interface modules, pull each module out about half way and then
reseat them. Do this for each module in slots G-L.

For more information regarding power see the:

Switches

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 2-6). Make sure 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. See page 2-5 for
some installation precautions.

2. Install switch modules (page 2-6). The 5400 zl switches have six or 12
universal slots for installing any of the HP Switch zl modules. Some of the
5406 zl and 5412 zl switches come with preinstalled modules. Depending
on where you will install your 5400 zl switch, it may be easier to install
the modules first. The modules are “hot swappable” though, so they can
also be installed and removed after the switch is powered on.

Note Make sure you use only HP Switch zl Modules in your 5400 zl switches.

3. Install power supplies (page 2-10). The 5406 zl switches supports up
to two power supplies. It may beeasier to install the power supplies before
mounting the switch. The switch must have at least one power supply to
operate.

4. Verify the switch passes self test (page 2-12). 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.
It may be easier to verify if the switch passes self test before mounting
the switch.

5. Mount the switch (page 2-14). The 5400 zl switches can be mounted in
a 19-inch telco rack, in an equipment cabinet, or on a horizontal surface.
An optional Rail Mounting Kit (5070-0145) is available for mounting 5400
zl switches in a cabinet suitable for shipping. See the installation details
for more information.

6. Install the Grounding Wire (page 2-17). If a grounding wire is to be
attached to the switch chassis, the grounding lug must be removed and a
wire crimped to it and the grounding lug must be reinstalled.

7. Connect the switch to a power source (page 2-18). Once the switch
is mounted, plug it in to the nearby main power source.

Switches

8. Connect a Power Supply Shelf (optional—page 2-18). You may wish
to use a Power Supply Shelf with your switch. To do so you must connect
the external power supply using the EPS cables supplied with the Power
Supply Shelf.

9. Connect the network devices (page 2-21). Using the appropriate
network cables, connect other switches, hubs, routers, computers,
servers, printers, and other network devices to the switch ports. For more
information, see “Connect the Network Devices” on page 2-21.

Note The 10/100/1000-T ports on the zl Modules comply with IEEE 802.3x

standard which includes the Auto MDI/MDI-X feature. This feature
allows you to use straight-through twisted-pair cable for all of your
twisted-pair network connections.

10. Connect a console to the switch (optional—page 2-22). 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
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.

WARNING

Installation Precautions

Follow these precautions when installing your 5400 zl switch:

■ 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.

The rack or cabinet should be adequately secured to prevent it
from becoming unstable and/or falling over.

■ Ensure a cover plate is installed on any empty switch power

supply or module slot. A cover plate is required for safe
operation, and to ensure proper switch cooling. Never have
more than one power supply or module slot uncovered at a
time while the switch is powered on.

■ To avoid energy and mechanical hazards, never allow any part

of your body, jewelry, tool, or other foreign object to enter any
module or power supply slots.

■ This unit may have more than one power supply cable. To fully

power down the switch, you must disconnect all power supply
cables from the unit.

2-5

Switches

Cautions

Installation Precautions (continued)

■ If the switch is to be shipped in a rack, use only an HP 10000 series rack

and a rail mounting kit (5070-0145) for each switch.

■ Ensure 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 and power supply, be sure the cord is adequately sized
for the switch’s current requirements. In addition, 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 and power supply.

■ When installing the switch, note that the AC outlet should be near the

switch and should be easily accessible in case the switch must be
powered off.

■ Ensure the switch does not overload the power circuits, wiring, and over-

current protection. Each power supply should be connected to a dedi­cated branch circuit to prevent tripping building circuit breakers. 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)1.

■ Allow three to four inches of space around the sides and back of the

switch to make sure the air flow for the switch is not restricted.

1

If you are installing any of the X2 transceivers the operating ambient temperature
should not exceed 40C (104F). See transceiver specifications in Appendix A
(page A-1).

1. Prepare the Installation Site

Cabling Infrastructure

Ensure the cabling infrastructure meets the necessary network specifications.
See Appendix B, “Cabling and Technology Information” on page B-1 for more
information.

Installation Location

Before installing the switch, plan its location and orientation relative to other
devices and equipment:

■ In the front of the switch, allow at least 7.6 cm (3 inches) of space for the

twisted-pair and fiber-optic cabling.

■ In the back of the switch, allow at least 10.2 cm (4 inches) of space for the

power cord and cooling.

■ On the sides of the switch, leave at least 7.6 cm (3 inches) for cooling.

2. Install Switch Modules

Install switch modules into the slots as shown in the illustration below. For
installation details, see the instructions in the manual that comes with the
module.

Caution Make sure you install only HP Switch zl Modules.

Avoid any electrostatic discharge problems by handling the modules only by
their bulkheads.

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

Module
Installation
Notes

■ Any of the supported Switch zl Modules can be installed in any of the slots.

■ The modules can be “hot swapped”, installed after the switch is already

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 2-26.

■ Ensure you fully insert the modules. That is, press the module into

the slot using the extractor handles, until the bulkhead on the module is
contacting the front face of the switch chassis.

3. (Optional) Install Another Power Supply

Caution The 5400 zl switches are designed to provide continuously operating PoE or

PoE+ power in the event of a single power supply failure with only a loss of
PoE or PoE+ power to lower priority ports.

If more than one power supply fails while the switch is at or near maximum
operating power (that is: the sum total of all PoE supply capacity minus the
largest supply, see chapter 2 and 4 of the PoE (Power over Ethernet) Devices
Planning and Implementation Guide) loss of all PoE power may result.

To return PoE power to the ports, without causing the switch to reboot, when
there are two or more power supplies still supplying 12V power, unplug the
power cord for 5 seconds and re-plug it for each power supply one at a time.

Another load-sharing redundant power supply (either a HP Switch zl 875 W
Power Supply (J8712A), an HP Switch zl 1500 W Power Supply (J8713A), or
an HP Switch1500 W PoE+ Power Supply (J9306A) can be installed in the back
of the switch. The 5406 zl switch can hold up to two power supplies and the
5412 zl switch can hold up to four power supplies.

The 875 W Power Supply (J8712A) can supply up to 273 watts for PoE power.
The 1500 W Power Supply (J8713A) can supply up to 900 watts at 220 volts for
PoE power. The 1500 W PoE+ Power Supply (J9306A) can supply up to 300
watts for PoE/PoE+ at 110-127 volts, or up to 900 watts for PoE/PoE+ at 200­240 volts.

To prevent overloading of the building circuits breakers, the second power
supply must be connected to a different AC power source from the other
supply. This also helps with redundancy, if one AC power source fails, the
switch will continue to run.

Install the second power supply into power slot number 2 as shown in Figure
2-3. Although these procedures show the 6-slot chassis, the procedures are
the same for the 12-slot chassis. The slot cover can be removed with either a
flat-bladed or Torx T-10 screwdriver. Retain the slot cover for future use.

Note The J8712A and J8713A power supplies can be paired within the same switch

or within the Power Supply Shelf. However,the J9306A power supply can only
be paired with another J9306A power supply within the same switch or within
the Power Supply Shelf. The J9306A power supply cannot be used with either
the J8712A or J8713A power supplies.

Caution The switch power supplies are hot swappable; they can be installed while the

switch is receiving power from the supply in the other slot. But, as indicated
by the caution statement on the power supply, the supply must not be
connected to AC power before being installed or removed.

CAUTION:

.
.

Disconnect AC power from the power supply BEFORE installing or
removing the supply. Otherwise, damage to the equipment may result.

.

Refer to the installation guide for proper power cord selection

For safety and proper switch cooling, if either of the power supply slots are
not being used, make sure to attach the cover plate over the slot. Please see
the “Installation Precautions” on page 2-5 for more information.

For installation details, see the instructions in the manual that comes with the
power supply.

Insert the power supply into the
opening, then slide it all the way in
until it connects to the switch. The
power supply face plate will be
flush with the back face of the
switch.

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
it is working properly by plugging it into a power source and verifying it passes
its self test.

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

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 The 5400 zl switches 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, please see the “Installation Precautions” on page 2-5.

2. Check the LEDs on the switch 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 the
Fault LED stays on for more than approximately 120 seconds or it starts
blinking, the self test has not completed correctly. Refer to chapter 4,
“Troubleshooting” for diagnostic help.

LED Behavior:

During the self test:

■ Initially, Power, Fault, Locator,and all the switch chassis LEDs are on. Then,

after approximately 30 seconds, all the module LEDs go on as the modules
receive power and code is downloaded to them, the Fault LED goes off,
and the chassis LEDs turn orange and then go off except Test, Fan, and
Power, which turn green.

■ When the download of code to the modules is completed, the module

LEDs go off. You may see each port LED go on briefly, in sequence, as the
port is tested.

■ For the duration of the self test, the Test LED stays on.

When the test completes successfully:

■ The Power LED stays on, and the Status LEDs on the switch chassis stay

on for the devices installed: one for each switch module installed, one for
each power supply installed, and one for all the fans.

■ The Fault, Locator, and Test LEDs are 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.

5. Mount the Switch

After the modules and optional power supply are installed and you have
verified the switch passes self test, you are ready to mount the switch in a
stable location. The 5400 zl switches can be mounted in these ways:

■ in a rack or cabinet

■ on a horizontal surface

Rack or Cabinet Mounting

The 5400 zl switches are designed to be mounted in any EIA-standard 19-inch
telco rack or in an equipment cabinet such as a server cabinet. If you are
installing the switch in an equipment cabinet, read the following “Equipment
Cabinet Note” on page 2-15.

Note

If you are installing the switch in an equipment cabinet, in place of the
12-24 screws supplied with the switch, use the clips and screws that came with
the cabinet. Plan which four holes you will be using in the cabinet and install
all four clips and partially install the two bottom screws, as described in step
2 on the previous page, before proceeding to step 3.

WARNING For safe operation, please read the “Installation Precautions” on page

2-4 and page 2-5 before mounting the switch.

1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting
brackets to the switch with the included 8-mm M4 screws.

For the 5406 zl switches, each bracket is attached with four screws as
shown in the following illustration.

Although these procedures show the 6-slot chassis, the procedures are
the same for the 12-slot chassis.

Horizontal Surface Mounting

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 Ensure the air flow is not restricted around the sides and back of the switch.

6. Install the Grounding Wire

If a grounding wire is to be attached to the switch chassis, the grounding lug
must be removed and a wire crimped to it and the grounding lug must be
reinstalled.

1. Use a #1 Phillips (cross-head) screwdriver and remove the grounding lug
and two screws from the back of the switch.

7. 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 a redundant power source is available, it is desirable to power one
switch power supply from the regular AC source, and the other power
supply from the redundant AC source. This will provide redundancy in AC
power to the switch, as long as the switch PoE power usage falls within
the capability of one power supply. If both power supplies are plugged
into a common AC source, there is still power supply redundancy, that is,
protection against power supply failure, but if the AC source fails, the
switch will lose all power.

2. Re-check the LEDs during self test. See “LED Behavior” on page 2-14.

8. (Optional) Connect a Power Supply Shelf

to the switch

1. Connect the supplied external power supply (EPS) cables to the switch
and to the Power Supply Shelf.

2. Tighten the thumb screws on all connectors to prevent any accidental
disconnects.

3. Plug the power supply cords into the power connector and into a nearby
properly grounded AC power source.

Installing the HP 5400 zl Switches

Installation Procedures

Installing the HP 5400 zl

Switches

The HP Switch zl Power Supply Shelf, (J8714A), hereafter referred to as the
EPS, is an accessory product for the 5400 zl switches. The EPS provides
External Power-over-Ethernet (PoE) or PoE+ power for up to two 5400 zl
switch products.

The EPS can supply up to 1800 watts (depending upon which power supplies
are installed) of PoE or PoE+ power to the switch if the internal PoE power
supply should fail, or as additional PoE power to be made available to the
switch’s PoE ports. For further information regarding the EPS PoE
capabilities, see the HP Power over Ethernet (PoE/PoE+) Devices Planning

and Implementation Guide and the HP Power Supply Shelf Installation and
Getting Started Guide, which are on the HP networking Web site at

www.hp.com/networking/support.

The EPS is an unmanaged power supply that only provides information by
way of LEDs.

EPS Operation

The EPS has a mechanism for detecting that it is connected to a valid switch
with an EPS cable. When the EPS is connected to a powered switch it will
provide additional PoE or PoE+ power to the switch within 2 seconds.

Caution Disconnecting the EPS (PoE power) cable with power flowing is not

supported, and could cause loss of PoE power to all network devices
connected to the switch. The Power Supply Shelf must be powered down
before disconnecting the EPS (PoE power) cable, if power is flowing. Only
the power supply to be disconnected must be powered down. The EPS cable
may be connected at any time.

Operating Characteristics of the EPS (J8714A)

The Power Supply Shelf has two EPS Ports. The EPS can provide a maximum
of up to 900 watts of PoE power to each of the two EPS ports depending on
which power supply is used. It is important to understand the PoE (and PoE+)
power requirements of the 5400zl switches because if the PoE power is not
planned and implemented correctly the end devices connected to the switch
ports may not receive power if an internal switch PoE power supply should
fail. For further information regarding the Power Supply Shelf PoE and PoE+
capabilities, see the HP Power over Ethernet (PoE/PoE+) Devices Planning

and Implementation Guide and the HP Power Supply Shelf Installation and
Getting Started Guide, which is on the HP networking Web site.

Although these examples show the EPS connecting to the 5406 zl switch, it
can also be connected to a 5412 zl switch in the same manner.These examples
also show the switch and the EPS using the J8713A power supply, the J8712A
power supply can also be used. It depends on how much PoE power is
required.

For more information on PoE requirements see the PoE (Power over
Ethernet) Devices Planning and Implementation Guide.

9. 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 5400 zl Switch. See the documen­tation accompanying the modules for cabling configurations and procedures
for those modules.

In general for all the modules, when a network cable from an active network
device is connected to the switch, the Link LED for the switch port should go
on. If the Link LED does not go on, use the table below to help solve the
problem, and see the module documentation for troubleshooting procedures.

Condition Diagnostic Tip

Port LED is
still

off when
a cable is
connected

Try the following procedures:

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

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

.

• Verify you have used the correct cable type for the connection:
– for all twisted-pair connections, the RJ-45 connectors on the 5400 zl switches allow you to use

either straight-through cable or crossover cable when the port is in the “Auto” configuration.

– for fiber-optic connections, verify 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.

See appendix B, “Switch Ports and Network Cables” for information on cables.

• Verify the port has not been disabled through a switch configuration change.

• Verify the connection parameters in the configurations of the switch port and the connected
device match. Mismatched configurations are a frequent cause of connection problems.

You can use the console interface, or, if you have configured an IP address on the switch, use the
web browser interface, or ProCurve Manager network management software to determine the
state and configuration 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.

10. (Optional) Connect a Console to the Switch

The 5400 zl switches 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 and other security features to control access to the switch

from the console, web browser interface, and network management
stations

2-23

Installing the HP 5400 zl Switches

Installation Procedures

Installing the HP 5400 zl

Switches

The console can be accessed through these methods:

■ Out-of-band: Connect a PC or VT-100 terminal, to be used as a console,

directly to the switch using the serial cable that comes with the 5400 zl
switches. 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 PC end of the 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.

The 5400 zl switches can simultaneously support one out-of-band console
session through the Console Port and one in-band TELNET 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, and flow control set to None

■ forWindows Terminalprogram, also disable(uncheck) the “Use Function,

Arrow, and Ctrl Keys for Windows” option

■ for the Hilgrave HyperTerminal program, select the “Terminal keys”

option for the “Function, Arrow, and Ctrl keys act as” parameter

If you want to operate the console using a different configuration, ensure 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.

Hot Swapping Switch Modules

Installing the HP 5400 zl

Switches

Hot Swapping Switch Modules

The switch modules can be “hot swapped” (except for the Management
Module, it is not hot swappable), that is installed or replaced while the switch
is powered on (See Module Installation Notes on page 2-6). 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

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 (since the last switch reboot), 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 a different type of module though, for example
a 10/100/1000-T zl Module is installed in place of a 4 port 10G X2 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 the following methods:

■ Pressing the Reset button on the front of the switch.

■ Unplugging and plugging in the power cord (power cycle). If two power

supplies are installed, both power cords would have to be unplugged.

■ Issuing the boot command from the switch console CLI, or selecting the

boot switch option from the switch console menu, the web browser

interface, or ProCurve Manager.

Until the switch is rebooted, the module will not operate and the Module
Status LED for the affected slot will continue to flash.

Figure 2-18. Edge switch configuration

When your network expands and the users need to access resources beyond
the edge of the local network, the 5400 zl switches are excellent platforms for
that expansion. With the flexibility of 6 slots, the high port count 10/100/1000­T zl Modules for local connections, and the availability of Gigabit speeds on
both copper and fiber cables, the 5400 zl switches can provide that access
beyond the edge for a high number of network users.

In the above illustration, two 5406 zl switches are connected to an HP Routing
Switch 9308, which can serve as a campus backbone or core switch.

The 1000 Mbps fiber-optic connections between the two 5406 zl switches and
the Routing Switch 9308 is by way of Gigabit-LX transceivers installed in
the transceiver port on the 20 port Gig-T plus 4 mini-GBIC zl Module in the
5406 zl switches and Gigabit-LX ports on the Routing Switch 9308. With the
Gigabit-LX connections, the distance between the 5406 zl switches and the
Routing Switch 9308 can be up to ten kilometers.

The connections are trunked, through a configuration change on the 5406 zl
switch, to provide redundancy and load sharing for higher bandwidth.

Optimizing the 10-GbE Port Configuration

The 10-GbE ports on the HP 5400 zl switch are designed to deliver full 10 Gbps
wire-speed to each port, where either one or two ports are in a linked state
with another device. When three or four 10-GbE ports are in a linked state,
when using an X2 (J8708A), CX4 (J8707A) or SFP+ (J9309A) module, the 10­GbE ports support an aggregate bandwidth of 28.8 Gbps across the linked
ports.

As illustrated in the figure below, internally, there are two 14.4-Gbps channels
between each of the 4 10-GbE ports and the switch fabric.

Figure 2-19. 10-GbE port architecture showing ports grouped by 14.4 Gbps channel.

When any two 10-GbE ports are in a linked state, each port automatically
operates on its own channel, which guarantees 10 Gbps of bandwidth for each
port. However, when more than two ports are in a linked state, ports A1 and
A4 are statically mapped to share one 14.4 Gbps channel, while ports A2 and
A3 are statically mapped to share the other 14.4 Gbps channel.

To summarize:

■ If only one port in a given channel is in a linked state, then that port

operates at wire speed and the other port uses no bandwidth.

■ If both ports in a given channel are in a linked state, then the 14.4 Gbps of

bandwidth is balanced fairly between the two ports.

For example, in an application where three ports are needed and it is impor­tant to ensure that port 1 always has a full 10 Gbps available, the connection
choices shown in the next figure would be used.

Figure 2-20. Guaranteeing 10 Gbps on a specific port.

Optimizing the 10-GbE Port Configuration with version
2 zl modules

The 10-GbE Module (J9538A) is designed to deliver additional performance
for zl switches. The 5400 zl has a fabric design that allows for optimal
performance with 10GbE v2 zl modules. When compared to the first genera­tion zl modules, the bandwidth channels have been improved to a maximum
capacity of 23.4 Gbps per channel, as opposed to 14.4 Gbps channels for the
standard zl modules. An eight port 10GbE module has two 23.4 Gbps channels,
for an aggregate of 46.8 Gbps of channel bandwidth. This means that up to

46.8 Gbps of data can be sent through a 10GbE module, or 23.4 Gbps per

channel. There is a fixed assignment between ports and channel bandwidth.
For an eight port 10GbE modules, Each 23.4 Gbps channel is allocated to 4
10GbE ports.

The channel assignment is as follows:

Interfaces 1,4, 6, and 8 are assigned to channel 1. Interfaces 2, 3, 5, and 7 are
assigned to channel 2. This is demonstrated in the figure 2-19.

Figure 2-21. Version 2 optimized 10-GbE port configuration

The 5400 zl can send 32 Gbps per module with 64 byte packets. This allows
for an oversubscription for the HP 8-port 10-GbE SFP+ v2 zl Module (J9538A)
on the 5400 zl, or 2 wire rate 10GbE ports.

For wire rate connectivity, do not connect more than one 10-GbE ports to a
channel. In the diagram, it is possible to connect one port from each channel
for wire rate connectivity. For example, ports 1 and 2 may both be connected
since they are in separate channels. If ports 1, 4, and 6 are connected, but
other ports are unused, the three ports will share up to 23.4Gbps of bandwidth.
If ports 1, 4, 6, and 8 are connected, the ports will share 23.4 Gbps of bandwidth
between the four ports.

management interfaces: the web browser interface and the SNMP manage­ment tool, ProCurve Manager,please see the Management and Configuration
Guide which is on the HP networking Web site.

Recommended Minimal Configuration

In the factory default configuration, the switch has no IP (Internet Protocol)
address and subnet mask, and no passwords. In this state, it can be managed
only through a direct console connection. To manage the switch through in­band (networked) access, you should configure the switch with an IP address
and subnet mask compatible with your network. Also, you should configure
a Manager password to control access privileges from the console and web
browser interface. Other parameters in the Switch Setup screen can be left at
their default settings or you can configure them with values you enter.

Many other features can be configured through the switch’s console interface,
to optimize the switch’s performance, to enhance your control of the network
traffic, and to improve network security. Once an IP address has been config­ured on the switch, these features can be accessed more conveniently through
a remote Telnet session, through the switch’sweb browser interface, and from
an SNMP network management station running a network management
program, such as ProCurve Manager.For a listing of switch features available
with and without an IP address, refer to “How IP Addressing Affects Switch
Operation” in the Management and Configuration Guide which is on the HP
networking Web site.

For more information on IP addressing, refer to “IP Configuration” in the
Management and Configuration Guide.

Getting Started With Switch Configuration

Getting Started With Switch

Configuration

Note By default, the switch is configured to acquire an IP address configuration

from a DHCP or Bootp server. To use DHCP/Bootp instead of the manual
method described in this chapter, see “DHCP/Bootp Operation” in the
Management and Configuration Guide which is on the HP networking Web
site.

Using the Switch Setup Screen

The quickest and easiest way to minimally configure the switch for manage­ment and password protection in your network is to use a direct console
connection to the switch, start a console session, and access the Switch Setup
screen.

1. Using the method described in the preceding section, connect a terminal
device to the switch and display the switch console command (CLI)
prompt (the default display).

The CLI prompt appears displaying the switch model number, for
example:

HP 5400zl#

2. At the prompt, enter the setup command to display the Switch Setup
screen. The following illustration is an example of a Setup screen with
default settings.

Getting Started With Switch

Configuration

Using the IP Address for Remote Switch
Management

With your 5400 zl switches, you can use the switch’s IP address to manage the
switch from any PC that is on the same subnet as the switch. Youcan use either
a Telnet session or a standard web browser to manage the switch.

Starting a Telnet Session

To access the switch through a Telnet session, follow these steps:

1. Ensure the switch is configured with an IP address and that the switch is
reachable from the PC that is running the Telnet session (for example, by
using a ping command to the switch’s IP address).

2. Start the Telnet program on a PC that is on the same subnet as the switch
and connect to the switch’s IP address.

3. You will see the copyright page and the message “Press any key to
continue”. Press a key, and you will then see the switch console command
(CLI) prompt, for example (assuming there is no password):

HP 5400zl#

Enter help or ? to see a list of commands that can be executed at the
prompt. Entering any command followed by help provides more detailed
context help information about the command. Entering any command
followed by ? displays a list of options that are available at that point in
the command entry.

Starting a Web Browser Session

Your 5400 zl switch can be managed through a graphical interface that you can
access from any PC or workstation on the network by running your web
browser and typing in the switch’s IP address as the URL. No additional
software installation is required to make this interface available; it is included
in the switch’s onboard software.

An example web browser interface screen is shown in the next illustration.

Getting Started With Switch

Configuration

Configuring the HP Wireless Edge
Services zl Modules (J9051A, J9052A)

Before beginning the configuration, backup the current configuration of the
switch.

The zl switch software must be updated to a version (K.12.40) that supports
the module. Visit www.hp.com/networking/support to obtain a supported
version; to verify module support, refer to the version’s Release Notes.

The HP Wireless Edge Services zl Module (J9051A) and the HP Redundant
Wireless Services zl Module (J9052A) must be running software version
WT.01.xx or later.

Note The term ‘module’ is used in this section to refer to both the HP Wireless Edge

Services zl Module (J9051A) and the HP Redundant Wireless Services zl
Module (J9052A).

There are four module configuration tasks required:

■ configuring an IP address for the module

■ configuring VLANs on the zl switch

■ determining a module configuration backup process

■ configuring wireless LAN services

Configuring an IP Address for the Module

By default, the module uses DHCP to get an IP address. The zl switch CLI has
a command context, the wireless-services context, for configuring and man­aging a module.

Note ‘HP’ is used here as a generic prompt for all zl switches.

■ To identify the slot in the zl switch where the module is installed, enter

the following command:

HP# show modules

■ To show the module’s IP address, enter the following command to access

the module’s wireless-services CLI context for the module:
HP# wireless-services <slot-id>

where <slot-id> is the slot in the zl switch where the module is installed.

■ To display the module’s IP address, enter:

HP(wireless-services-id)# show ip interfaces

The following example enters the wireless-services context of a module
installed in Slot B of a zl switch and then displays the IP address assigned by
DHCP to the module:

HP# wireless-services b
HP(wireless-services-B)#show ip interface
Interface IP-Address/Mask Status Protocol
vlan1 10.35.12.24(DHCP) up up
HP(wireless-services-B)#

If no DHCP service is available or if the administrator wishes to manually set
the Wireless Edge Services zl Module IP Address, it can be specified through
the CLI. From the wireless-services context, enter the config context and use
the interface vlan1 command to configure the vlan1 interface.Use the following
command to set the IP address:

HP(wireless-services-<slot-id>)(config-if)# ip address <IP>

where <slot-id> is the slot in the zl switch where the module is installed.

<IP> is the IP address in CIDR notation (/mask bit number), or

dhcp which will use DHCP to obtain an IP address.

In the following example, the CLI commands set the module’s IP address to

10.245.22.14 with a 21-bit subnet mask.

HP(wireless-services-B)#configure
HP(wireless-services-B)(config)#interface vlan1
HP(wireless-services-B)(config-if)#ip address 10.245.22.14/21
HP(wireless-services-B)(config-if)#show ip interface
Interface IP-Address/Mask Status Protocol
vlan1 10.245.22.14/21 up up

HP(wireless-services-B)(config-if)#

If necessary, use the following command from the wireless-services andconfig
contexts to set or change the default gateway:

HP(wireless-services-B)(config)#ip default-gateway <ip-addr>

where <ip-addr> is the numeric IP address of the default gateway, for

example 10.1.2.1.

Configuring VLANs on the zl Switch

In a wireless services-enabled zl switch, the Wireless Edge Services zl Module
and the Redundant WirelessServices zl Module use ports on the switch to pass
wired and wireless traffic to and from the network. An uplink VLAN,
containing the module’suplink port, communicates with the wired side of the
network; downlink radio port VLANs, containing the module’sdownlink port,
communicate with the wireless side of the network.

See the Wireless Edge Services zl Module Supplement to the zl Switch
Management and Configuration Guide for detailed information to set up and
configure VLANs on the zl switch for module communications. This manual
is available at www.hp.com/networking/support.

Determining a Module Configuration Backup Process

The module’s configuration files are stored on the module, not on the zl switch,
unlike other zl modules. An external FTP or TFTP server must be used to back
up and restore a module’s complete configuration.

The switch does save a small subset of the module’s configuration that allows
the switch to locate the full configuration file on the external FTP or TFTP
server and to validate it using a checksum. The stored subset of a module’s
configuration file appears in a show running-config or show config command
as uneditable text.

For more information on configuring and managing configuration files on an
external FTP or TFTP server, see the HP Wireless Edge Services zl Modules

Management and Configuration Guide, available at www.hp.com/networking/

Configuring Wireless LAN Services

To configure wireless LAN services on a wireless services-enabled zl switch,
use one of the following management interfaces for the module:

■ Web browser interface — Accessed through a Web browser, this

intuitive interface provides comprehensive information to help you
manage and monitor your company’s wireless services. The menus
and online help guide you through configuration steps. See the HP

Wireless Edge Services zl Modules Management and Configuration
Guide for information on using the Web browser interface to

configure and manage a module.
To run the Web browser interface for the HP Wireless Edge Services zl

Module, your workstation must be running Java Virtual Machine (JVM).
If your workstation is not running the JVM and you attempt to open the
module’sWebbrowser interface, the workstation will automatically try to
access the Internet and download the JVM.

■ Command line interface (CLI) — Available through a serial, Telnet, or

Secure Shell (SSH) session to the zl switch, the wireless-services
context, accessed from the zl switch’s CLI config context, provides a
complete set of commands to configure, manage, and troubleshoot
your wireless services.

The CLI commands available in the wireless-services context of the zl
switch CLI are documented in an appendix of the HP Wireless Edge
Services zl Modules Management and Configuration Guide. Refer to this
manual for more information.

The Web browser interface simplifies both management and configuration
tasks, and is recommended in most instances.

Hot Swapping The HP 5400 zl Switch supports “hot swapping” - the ability to replace the

following hardware components while the switch is operating: a fan tray,
power supply (if a second power supply is installed), interface module.

The Management module and its components are not hot swappable.

The hot swapping feature allows you to remove or install modules without
powering off or rebooting the switch. Swapped-in modules are recognized by
the switch and begin functioning immediately after they are installed.

Caution The HP E5400 zl Switch and its components are sensitive to static discharge.

Use an antistatic wrist strap and observe all static precautions when hot
swapping components. For example, connect your antistatic wrist strap to the
ground point on the front of the switch, above the rightmost power supply bay.

WARNING This unit may have more than one power supply cable. To fully power

down the switch, you must disconnect all power supply cables from the
unit.

Troubleshooting

This chapter describes how to troubleshoot your 5400 zl switches. Note that
thisdocument describes troubleshootingmostly from ahardware 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 ProCurve Manager, the SNMP-based
network management tool. For more information, see the chapter “Trouble­shooting” in the Management and Configuration Guide, which is on the HP

Troubleshooting

Basic Troubleshooting Tips

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

■ 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

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, “Cabling and Technology Information”
on page B-1 for pinouts and correct cable wiring. A category 5 cable tester
is a recommended tool for every 100Base-TX and 1000Base-T network
installation.

■ Improper Network Topologies. It is important to make sure you have

a valid network topology. Common topology faults include excessive
cablelength 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.

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.

With your 5400 zl switches, 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 ProCurve Manager.

The 5400 zl switches also support Trunking, which allows multiple
network cables to be used for a single network connection without
causing a data path loop. See the Management and Configuration Guide
for more information on Spanning Tree and on Trunking, which is on the
HP networking Web site. See page 5-1 for details.

5-3

Troubleshooting

Basic Troubleshooting Tips

Troubleshooting

■ Connecting to devices that have a fixed full-duplex configuration.

The RJ-45 ports on the 5400 zl switches are all configured as “Auto”. 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 configured to Auto, the switch will

automatically negotiate both link speed and communication mode

• if the connected device has a fixed configuration, for example 100

Mbps, at half or full duplex, the switch will automatically sense the
link speed, but will default to a communication of half duplex

Because the 5400 zl switches behave in this way (in compliance with the
IEEE 802.3 standard), if a device connected to the switch has a fixed
configuration at full duplex, the device will not connect correctly to the
switch. The result will be high error rates and very inefficient communi­cations between the switch and the device.

Ensure that all devices connected to the 5400 zl switches are configured
to auto negotiate, or are configured to connect at half duplex (all hubs are
configured this way, for example).

If necessary though, you can modify the configuration of the ports on the
5400 zl switches to match the configuration of the connected device. Use
the switch console, the web browser interface, or ProCurve Manager to
modify the port configuration.

■ Check the port configuration. A port on your 5400 zl switch may not

be operating as you expect because it has been put into a “blocking” state
by Spanning Tree, GVRP (automatic VLANs), or LACP (automatic
trunking). (Note that the normal operation of the Spanning Tree, GVRP,
and LACP features may put the port in a blocking state.) Or, the port just
may have been configured as disabled through software.

Use the switch console to determine the port’s configuration and verify
that there is not an improper or undesired configuration of any of the
switch features that may be affecting the port. See the Management and
Configuration Guide which is on the HP networking Web site. See page

5-1 for details.

For more information on possible network problems and their solutions, refer
to the technical note “Troubleshooting LAN Performance and Intermittent
Connectivity Problems”, which can be found on the HP networking Web site

Problem Solution

➊

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

1. Verify the power cord is plugged into an active power source and to the switch.
Ensure 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 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.

➋

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

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.

➌

The switch has
experienced a
backplane failure
during self test.

The failure may be just in the communications with a single module slot, or it might
be more significant. Start a console session with the switch, and at the CLI prompt
issue the command show logging. In the event log that is displayed, there will be
messages that describe the extent of the problem. If the problem is with individual
slots, the remainder of the switch slots will be fully operational and can be used until
you get a chance to replace the switch.

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/W

arranty card for more information.

➍

The module
installed in the slot
that corresponds to
the letter that is
blinking is an
invalid module.

The fact that the Link and Mode LEDs never are lit on the module indicates that it is
a Switch gl module and should not be used in your zl switch.

Ensure you have installed a zl module in the slot. HP xl/gl modules will fit
in the slot, but they are not compatible with your HP zl switch. Check to
ensure the module has a Blue

“zl module” symbol on it.

Remove the module from the switch and replace it with a zl module, or

recover the slot with the cover plate. Y

ou can remove and replace the module
without having to power down the switch. Call your HP authorized LAN dealer, or
use the electronic support services from HP to get information on supported Switch
zl modules. The modules that are available as of the printing of this manual are listed
on page 1-16.

➎

The module
installed in the slot
that corresponds to
the letter that is
blinking has
experienced a self
test or initialization
fault.

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

Since the Link and Mode LEDs on the module were lit at least briefly, that indicates
that the module did receive power from the switch, but the subsequent download
process failed. Either the module is faulty, or it is a new module type that is not yet
supported by the operating code on the switch.

As HP networking introduces new modules for your HP Switch zl, you may have to
update the switch with new operating code that supports the new module. The
documentation that came with the module will indicate which version of the
operating code is needed to support the module. The modules that are supported in
your Switch zl, as of the printing of this manual, are listed on

page 1-16 under “Switch

Features”. The latest code can be downloaded from the HP networking Web site at

www.hp.com/networking/support.

First verify the switch has a version of code that supports the module that is
indicating the fault. If the module is not one of the ones listed on

page 1-16, check

the module documentation to see what version of switch code is needed. Download
the new code and retest the module.

If you have the correct code installed in the switch, try removing and reinstalling the
module. You can do this without having to power down the switch. When the module
is reinstalled, it will be retested automatically.

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.

➏

In the slot
corresponding to
the letter that is
blinking, a module
was installed that is
a different type
than the previously
installed module,
and the switch has
not yet been reset.

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 blinking LED informs you that this change of module types has occurred. The
module will not work properly until the switch is reset.

You can reset the switch by any of these methods:

• pressing the Reset button.

• power cycling the switch.

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

ProCurve Manager.

➐

The network port
for which the Link
LED is blinking has
experienced a self
test or initialization
failure.

During the module self test, described in tip number 4 earlier in this table, each
network port is also tested. If the port self test fails, the individual port is not usable,
but the rest of the ports on the module, which have passed their self test, will
continue to operate normally.

If the port is a transceiver, verify it is one of the transceivers supported by the
Module. Unsupported transceivers will be identified with this fault condition. The
supported transceivers are listed in the module Installation Guide. The transceivers
are also tested when they are “hot-swapped”--installed or changed after the
Module is installed and receiving power from the switch.

To verify the port has failed, try removing and reinstalling the module, as described
in tip number 4. For the transceivers, you can just remove and reinstall the
transceiver without having to remove the module. If the port fault indication
reoccurs, and you need to be able to use the port, you will have to replace the
transceiver or the module. In the mean time, all the other module ports will operate
normally.

➑

A fault condition
has been detected
on the power
supply installed in
the slot
corresponding to
the blinking
number.

Try removing and reinstalling the power supply.

Caution: Ensure 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 HP
authorized LAN dealer, or use the electronic support services from HP networking
to get assistance. See the Customer Support/Warranty card for more information.

➒

One or more of the
switch cooling fans
may have failed.

Try 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 multiple 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 networking to get assistance. See the Customer Support/Warranty card for more
information.

➓

The network port
for which the Link
LED is blinking has
been disabled
because port
security has been
configured on the
switch and a
security violation
has been detected
on the port.

For the Port Security feature, you can configure the switch so that whenever a
security violation is detected on a port, the switch will disable the port. When a port
is disabled by this feature, the port Link LED will be continuously flashed at the fast
rate of 0.8 seconds per cycle. The blinking continues until you clear the security
violation through the switch console. In the console, you can view the identity of the
connected device that committed the security violation.

Once the security violation is cleared, you must re-enable the port through the
console.

For more information on the Port Security feature, see the Management and

Configuration Guide which is on the HP networking Web site. See

page 5-1 for

details.

Troubleshooting

l

The network
connection is not
working properly.

Try the following procedures:

• For the indicated port, verify both ends of the cabling, at the switch and the

connected device, are securely connected.

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

correctly

.

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

– for any of the twisted-pair connections, in the default configuration (Auto),

either a straight-through or a crossover cable can be used and the switch will
automatically adjust its operation. See the “HP Auto-MDIX Feature”
description on page B-7 for more information.

Note: If the module configuration is changed to one of the fixed
configuration options though (for example, 100-Full Duplex), then the port

operates as MDI-X only and the correct type of cable must be used. in
general, for connecting to an end node (MDI port), use straight-through
cable; for connecting to MDI-X ports on hubs, other switches, and routers,
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, and
that both devices are transmitting correctly

.

• For a 1000 Mbps connection, verify the network cabling complies with the IEEE

802.3ab standard. The cable should be installed according to the ANSI/TIA/EIA­568-A-5 specifications. Cable testing should comply with the stated limitations
for Attenuation, Near

-End Crosstalk, Far-End Crosstalk, Equal-Level Far-End

Crosstalk (ELFEXT), Multiple Disturber ELFEXT, and Return Loss.
The cable verification must include all patch cables from any end devices,

including the switch, to any patch panels in the cabling path.

• Verify 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 ProCurve Manager network
management software to determine the state of the port and re-enable the port
if necessary

.

• Verify the switch port configuration matches the configuration of the attached

device. For example, if the switch port is configured as “Auto”, the port on the
attached device also MUST be configured as “Auto”. Depending on the port type,
twisted-pair or fiber

-optic, if the configurations don’t match, the results could be

a very unreliable connection, or no link at all.

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

HP networking tools

The 5400 zl switches 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

performance 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:

■ ProCurve Manager - an SNMP-based network management tool included

with your switch

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

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

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

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

See the “Troubleshooting” chapter in the Management and Configuration
Guide for more information on using these software tools to diagnose and
manage your switch, which is on the HP networking Web site. See page 5-1 for

Reasons for Resetting the Switch

Generally, you only need to reset the switch when it needs to recognize a
change in its hardware or software (console) configuration. Some
circumstances in which you will need to reset the switch are:

■ Installing a module in a slot that was previously occupied by a different

type of module, the switch must be reset after the new module is installed
so the switch processor can properly initialize and configure the new
module type.

Note When a module is exchanged for a different type, until the switch is reset

the module will not operate, the Module Status LED (orange) for the slot
will blink, the chassis fault LED will blinksimultaneously,and all the LEDs
on the module will stay on continuously.

■ Changing certain switch configuration parameters through the console

interface. (In this case, the console provides indications when the switch
must be reset for the configuration change to be activated.)

You do not need to reset the switch when:

■ Installing a module in a previously unused slot.

■ Replacing a module with the same type of module.

Methods of Resetting the Switch

You can reset the switch by any of these methods:

■ pressing the Reset button. On the 5400 zl switches, this is the Reset button

on the Management Module.

■ power cycling the switch (if both power supplies are being used, you will

have to disconnect both power cords)

■ issuing the boot command from the switch console CLI, or selecting the

Reset or Boot option from the switch console menu, web browser inter-

face, or ProCurve Manager

Troubleshooting

Hardware Diagnostic Tests

Troubleshooting

Testing the Switch by Resetting It

If you believe 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

■ Select the reset or reboot option from the console, web browser interface,

or ProCurve Manager.

Power cycling the switch, pressing the Reset button, and the software reset
or reboot options all 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 countersto be reset to zero and cause
the System Up Time timer to reset to zero. Neither of these reset procedures
causes any changes to the switch configuration.

Checking the Switch LEDs

The self-test passes if the Fault and Test LEDs on the front of the switch go
off after approximately 90 to 150 seconds depending on the number and type
of modules installed in the switch. If these LEDs stay on longer than 180
seconds or begin blinking, the switch, or a module, or an individual transceiver
may have to be replaced as indicated by the LEDs.

See “Diagnosing With the LEDs” on page 5-4 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 2-23. Then, when you reset the switch, note the messages that are

displayed.

Hardware Diagnostic Tests

Troubleshooting

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, 100Base-TX, or 1000Base-T
standards, as appropriate for the switch port type that the cable is connected
to.The twisted-pair cables attached to the 5400 zl switches must be compatible
with these standards.To verify your cable is compatible with these standards,
use a qualified cable test device.

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

Testing Switch-to-Device Network Communications

You can perform the following communication tests to verify 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 Management and Configuration
Guide which is on the HP networking Web site. See page 5-1 for details.

These tests can also be performed from an SNMP network management
station running a program that can manage the switch, for example, ProCurve
Manager.

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 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.

Troubleshooting

Restoring the Factory Default Configuration

Troubleshooting

Restoring the Factory Default
Configuration

As part of your troubleshooting process, it may become necessary to return
the switch configuration to the factory default settings. This process momen­tarilyinterrupts 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, if one is configured.

Note This process removes all switch configuration changes that you have made

from the factory default settings. This includes, for example, configuration of
VLANs, spanning tree, trunks, stacking, meshing, routing, and security.
Returning the configuration of these features to their factory default settings
(usually disabling them) may result in network connectivity issues.

If the switch has a valid configuration, and you are restoring the factory default
settings for a reason other than configuration problems, you should save the
switch configuration prior to performing the factory default reset. Then, after
the reset and resolution of the original problem, you can restore the saved
configuration to the switch. For both the save and restore processes, you can
use the console copy command. See the switch Management and Configura-
tion Guide which is on the HP networking Web site. See page 5-1 for details.

You can restore the factory default configuration either on the switch itself or
through the switch console.

To execute the factory default reset on the switch, 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. As soon as the Test LED begins to flash, release the Clear button.
The switch will then complete its self test and begin operating with its

configuration restored to the factory default settings.

To restore the factory default configuration using the console, execute the
erase startup config command from the console command prompt.

specifications, as described in Addendum 5 to the TIA-568-A standard (ANSI/
TIA/EIA-568-A-5).

Because of the increased speed provided by 1000BASE-T (Gigabit-T), network
cable quality is more important than for either 10BASE-T or 100BASE-TX.
Cabling plants being used to carry 1000BASE-T networking must comply with
the IEEE 802.3ab standards. In particular, the cabling must pass tests for
Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT).
Additionally, unlike the cables for 100BASE-TX, the 1000BASE-T cables must
pass tests for Equal-Level Far-End Crosstalk (ELFEXT) and Return Loss.

When testing your cabling, be sure to include the patch cables that connect
the switch and other end devices to the patch panels on your site. The patch
cables are frequently overlooked when testing cable and they must also
comply with the cabling standards.

Note on 10GBASE-T Cable Requirements. The Category 6 networking
cables that work for 1000BASE-T connections may work for 10GBASE-T, as
long as the distance is less than 55m and the cable installation has been tested
for compliance to IEEE requirements. But, for the most robust connections,
you should use cabling that complies with the Category 6A or Category 7
specifications, as described in the TIA-568-C (ANSI/TIA-568-C.2) and ISO/IEC
11801 standards.

10GBASE-T is a sophisticated technology that relies upon high quality cable
installations. It is sensitive to Alien Near End Crosstalk (ANEXT) which can
arrive upon the cable due to cables placed in close proximity to the data
cables. It is recommended that cable dressing be done carefully and in
compliance with recommendations in the TIA TSB-155A.

Like 1000BASE-T, 10GBASE-T requires testing of all the crosstalk and return
loss parameters described above, and also ANEXT.

In addition to ANEXT, 10GBASE-T is more sensitive to external electrical
noise in the environment. It is recommended that radio transmitters and other
sourcesof high frequency continuouswave radio frequency be kept away from
LAN cables.

When testing your cabling, be sure to include the patch cables that connect
the switch and other end devices to the patch panels on your site. The patch
cables are frequently overlooked when testing cable and they must also
comply with the cabling standards. For 10GBASE-T, Category 6 patch cables
are sensitive to movement once link has been established, and could cause
link to drop if moved. Therefore HP recommends using Category 6A patch
cables, or using cable management options to tie down (dress) the Category
6 patch cables so they cannot move.
