Introducing the Switch
The HP ProCurve 2520G-PoE Switches are multiport switches that can be used
to build high-performance switched workgroup networks. These switches are
store-and-forward devices that offer low latency for high-speed networking.
The 2520G-PoE switches also support Power over Ethernet (PoE)
technologies.
HP ProCurve 2520G-8-PoE Switch (J9298A)
HP ProCurve 2520G-24-PoE Switch (J9299A)
Throughout this manual, these switches will be referred to as the Switch
2520G-8-PoE and the Switch 2520G-24-PoE.
■
The Switch 2520G-8-PoE has 8 auto-sensing 10/100/1000Base-T RJ-45
ports with two Gigabit Uplink dual-personality ports (ports 9 and 10).
■
The Switch 2520G-24-PoE has 24 auto-sensing 10/100/1000Base-T RJ-45
ports, four of which are dual-personality ports (ports 21 through 24).
■
Power-over-Ethernet or PoE power - Both 2520G-PoE switches
support PoE technology, which allows IP telephones, wireless LAN
Access Points and other appliances to receive power as well as data over
existing LAN cabling, without needing to modify the existing Ethernet
infrastructure. The Switch 2520G-24-PoE is designed with an internal PoE
power supply capable of providing 195 watts of PoE power (67 watts on
the Switch 2520G-8-PoE). Each Switch port can provide up to 15.4 watts
(or 7.5 watts if all ports are used) of PoE power to connected devices. For
further information regarding PoE power, see the PoE Planning and
Implementation Guide, which is on the ProCurve Web site at
www.hp.com/go/procurve/manuals.
1-1
Introducing the Switch
Dual-personality ports use either the 10/100/1000Base-T RJ-45 connector, or a
supported ProCurve mini-GBIC (Small Form Factor Pluggable (SFP)) for
fiber-optic connection. By default, the RJ-45 connectors are enabled.
These switches can be directly connected to computers, printers, and servers
to provide dedicated bandwidth to those devices, and you can build a switched
network infrastructure by connecting the switch to hubs, other switches, or
routers. In addition, the 2520G-PoE switches offer full network management
capabilities.
Using ProCurve mini-GBICs, these products support optional network
connectivity with the following speeds and technologies:

Installation Precautions
WARNING
■
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 devices at the bottom and progressively
lighter devices installed above.
Cautions
■
Wall-mount the Switch 2520G-8-PoE with network ports facing up
(away from the floor). Do not wall-mount the switch with the
network ports facing down (toward the floor) or ventilation ducts
facing up or down.
■
Use only the AC/DC power adapter supplied with the Switch 2520G-8-PoE
for connection to an AC power source.
■
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, ensure 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. If the supplied power cord does not fit,
contact ProCurve Networking support.
■
When installing the switch, 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 overcurrent 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. 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 50°C (122°F). This includes a fully-enclosed
rack. Ensure the air flow around the sides and back of the switch is not
restricted. Leave at least 7.6 cm (3 inches) for cooling.
■
Ensure all port covers are installed when the port is not in use.

Installing the Switch
Installation Procedures
Installation Procedures
These steps summarize your switch installation. The rest of this chapter
provides details on these steps.
1.
Prepare the installation site (page 2-5). 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 an appropriate location for the switch. See page
2-3 for some installation precautions.
2.
Verify the switch passes self test (page 2-6). Plug the switch into a
power source and observe that the LEDs on the switch’s front panel
indicate correct switch operation.
3.
Mount the switch (page 2-8). The 2520G-PoE switches can be mounted
in a 19-inch telco rack, in an equipment cabinet, on a wall, or on a
horizontal surface.
4.
Connect power to the switch (page 2-15). Once the switch is mounted,
plug it into the main power source.
5.
Connect the network devices (page 2-17). Using the appropriate
network cables, connect the network devices to the switch ports.
6.
(Optional) Install mini-GBICs (page 2-18). The switch has two or four
slots for installing mini-GBICs. Depending on where you install the switch,
it may be easier to install the mini-GBICs first. Mini-GBICs can be hot
swapped—they can be installed or removed while the switch is powered
on.
7.
(Optional) Connect a console to the switch (page 2-20). 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, from an SNMP
network management station, or through a Telnet session. Configuration
changes can be made by using the included console cable to connect a PC
to the switch’s console port.
At this point, your switch is fully installed. See the rest of this chapter if you
need more detailed information on any of these installation steps.

Installing the Switch
Installation Procedures
LED Behavior
During the self test:
•
Initially, all the switch and port LEDs are on. 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 Test LED stays on.
When the self test completes successfully:
•
The Power, PoE and Fan (Switch 2520G-24-PoE only) LEDs remain on.
•
The Fault, Locator and Test LEDs stay off.
•
The Act LED remains on indicating the default port LED mode.
•
The port LEDs on the front of the switch 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 (Act), the Mode LEDs should be
blinking indicating port activity.
– If the ports are not connected to active network devices, the Link
and Mode LEDs will stay off.
If the LED display is different than what is described above, especially if
the Fault and Test LEDs stay on for more than 60 seconds or they start
flashing, the self test has not completed correctly. Refer to chapter 4,
“Troubleshooting” for diagnostic help.
3. Mount the Switch

browser interface, and network management stations
The console can be accessed through these methods:
■
Out-of-band: The 2520G-PoE switches come with a serial cable for
connecting a PC or VT-100 terminal, to be used as a console, directly to
the switch.
■
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. For more
information on IP addressing and on starting a Telnet session, see
chapter 3, “Configuring the Switch”, in the Management and
Configuration Guide, which is on the ProCurve Web site at www.hp.com/
go/procurve/manuals.
The 2520G-PoE switches can simultaneously support one out-of-band console
session through the Console Port and in-band Telnet console sessions.

Figure 2-16. Basic desktop configuration
The 2520G-PoE switches are designed to be used as desktop switches to which
end nodes, printers and other peripherals, and servers are directly connected,
as shown in the above illustration. The switches can also supply PoE power
to end devices such as IP telephones.
2-22
Installing the Switch
Sample Network Topologies
As shown in the above illustration, the IP telephones can be connected in line,
that is, between the switch and the end device, in this case a PC. The IP
telephones have two ports, one in and one out. Therefore the phone receives
voice and power from the switch and the PC can send and receive data through
the phone to the switch.
The end node devices are connected to the switch by straight-through or
crossover twisted-pair cables. Either cable type can be used because of the
Auto-MDIX feature on the 2520G-PoE switches.

Installing the Switch
Sample Network Topologies
The 2520G-PoE switches also work well as segment switches. That is, with
their high performance, they can be used for interconnecting network
segments—simply connect the network devices that form those segments to
the 2520G-PoE switches.
In the illustration above, 2520G-PoE switches with PCs, printers, and local
servers attached, are both connected to a non-PoE switch. The devices
attached to the two 2520G-PoE switches can now communicate with each
other through the non-PoE switch. They can also all communicate with the
server that is connected to a 1000Base-T port on the Switch 2520G-24-PoE.
As shown in the illustration above, the IP telephones have been inserted in
between the Switch 2520G-24-PoE and the PCs, and wireless access points
(WAPs) have been connected to the Switch 2520G-24-PoE and a Switch 2520G8-PoE. Both the telephones and WAPs will receive PoE power from each of
the switches. Only devices directly connected to PoE switches can receive
PoE power. Devices connected to the non-PoE switch cannot receive PoE
power.
Because the 2520G-PoE switches have the Auto-MDIX feature, the
connections between the switches and end nodes or servers can be through
category 5 straight-through or crossover twisted-pair cable. Category 3 or 4
cable can also be used if the connection is 10 Mbps only. In all cases, the device
ports must be configured to auto negotiate the link characteristics for this
feature to work.
The connections between the switches are through fiber-optic cabling
connected to Gigabit transceivers. All the devices on these network segments
can access other network resources that are connected elsewhere on the
network. Always remember when connecting fiber-optics that all components
match in specification.
2-24
Installing the Switch
Sample Network Topologies
Stacking the Switch
The 2520G-PoE switches can be connected together, through standard
network connections, and managed through a single IP address. Up to 16
switches can be connected together in such a “virtual stack”.
You identify a 2520G-PoE Switch as the “Commander” and give that switch an
IP address. Up to 15 other switches in the network can then easily be
configured as Members of the stack and managed through the Commander’s
IP address. The management includes Telnet access and Web browser
interface access to the Commander and to each Member switch through the
Commander.
For more information on stacking your switch, see the Management and
Configuration Guide, which is on the ProCurve Web site at www.hp.com/go/
procurve/manuals.

Configuring the Switch
This chapter is a guide for using the console Switch Setup screen to quickly
assign an IP (Internet Protocol) address and subnet mask to the switch, set a
Manager password, and, optionally, configure other basic features.
For more information on using the switch console and the Web browser
interface, please see the Management and Configuration Guide, which is on
the ProCurve Web site at www.hp.com/go/procurve/manuals.
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’s Web browser interface,
and from an SNMP network management station running a network
management program. 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.
For more information on IP addressing, refer to “IP Configuration” in the
Management and Configuration Guide.
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.

Configuring the Switch
Recommended Minimal Configuration
Using the Console 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 line
interface (CLI) prompt (the default display).
The CLI prompt appears, for example:
ProCurve_2520G-24-PoE#
2.
At the prompt, enter the setup command to display the Switch Setup
screen. The following illustration shows the Setup screen with the default
settings.
Figure 3-1. Example console setup screen
3.
Use the [Tab] key to select the Manager Password field and enter a manager
password of up to 16 printable ASCII characters.
4.
[Tab] to the IP Config (DHCP/Bootp) field and use the Space bar to select the
Manual option.

Using the IP Address for Remote Switch Management
Using the IP Address for Remote Switch
Management
With your switch, you can use the switch’s IP address to manage the switch
from any PC that is on the same subnet as the switch. You can 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.
Make sure 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

(CLI) prompt, for example:
ProCurve_2520G-24-PoE#
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
The 2520G-PoE switches 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.
For more information on using the Web browser interface, please see the
Management and Configuration Guide.
An extensive help system is also available for the Web browser interface. To
access the Help system, access to the Internet is required. Otherwise, the Help
files must be downloaded to a local management server.

Troubleshooting
This chapter describes how to troubleshoot your ProCurve 2520G-PoE
Switches. This document describes troubleshooting mostly from a hardware
perspective. You can perform more in-depth troubleshooting on these devices
using the software tools available with the switches, including the fullfeatured 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 ProCurve Web site at www.hp.com/go/procurve/manuals.

basic troubleshooting tips (page 4-1)
■
diagnosing with the LEDs (page 4-4)
■
proactive networking tools (page 4-9)
■
hardware diagnostic tests (page 4-10)

■
HP Customer Support Services (page 4-13)
Basic Troubleshooting Tips
Most problems are caused by the following situations. Check for these items
first when starting your troubleshooting:
■
Connecting to devices that have a fixed full-duplex configuration.
The RJ-45 ports are configured as “Auto”. That is, when connecting to
attached devices, the switch operates 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 mode of half duplex.
4-1
Troubleshooting
Basic Troubleshooting Tips
Caution
Because the 2520G-PoE 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 all devices connected to the 2520G-PoE switches are configured
to auto negotiate, or are configured to connect at half duplex (all hubs are
configured this way, for example).
■
Faulty or loose cables. Look for loose or obviously faulty connections.
If the cables 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 A, “Cabling and Technology Information
Specifications” 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
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. Sample topologies are shown at the end of
chapter 2 in this book, and some topology configuration guidelines can
be found online at the ProCurve Web site, www.hp.com/go/procurve.
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.
For your Switch, 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 or the
Web browser interface.
The 2520G-PoE switches also support Trunking, which allows multiple
network cables to be used for a single network connection without
causing a data path loop. For more information on Spanning Tree and
Trunking, see the Management and Configuration Guide, which is on
the ProCurve Web site at www.hp.com/go/procurve/manuals.

Troubleshooting
Basic Troubleshooting Tips
■
Check the port configuration. A port on your 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. For more information, see
the Management and Configuration Guide.
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 ProCurve Web site,

Problem
Solution
➊
The switch is not
plugged into an
active AC power
source, or the
switch’s power
supply may have
failed.
1. Verify the power cord is plugged into an active power source and to the switch. Make
sure these connections are snug.
2. Try power cycling the switch by unplugging and plugging the power cord back in.
3. If the Power LED is still not on, verify 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 ProCurve Networking authorized network reseller, or
use the electronic support services from HP to get assistance. See the Software License,
Warranty and Support booklet 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 ProCurve Networking authorized network reseller, or use the electronic support
services from HP to get assistance. See the Software License, Warranty and Support
booklet for more information.
➌
The switch has
experienced a
software failure
during self test.
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 or by typing “Show log” at the Manager command prompt (#).
If necessary to resolve the problem, contact your ProCurve Networking authorized
network reseller, or use the electronic support services from HP to get assistance. See
the Software License, Warranty and Support booklet for more information.
➍
One of the switch
cooling fans may
have failed.
(2520G-24-PoE
Switch only)
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 of the
fans has failed. In switches with multiple fans the switch may continue to operate under
this condition if the ambient temperature does not exceed normal room temperature, but
for best operation, the switch should be replaced. Contact your ProCurve Networking
authorized network reseller, or use the electronic support services from HP to get
assistance. See the Software License, Warranty and Support booklet for more information.
➎
The network port
for which the LED
is flashing has
experienced a
self test or
initialization
failure.
Try power cycling the switch. If the fault indication reoccurs, the switch port may have
failed. Call your ProCurve Networking authorized network reseller, or use the electronic
support services from HP to get assistance. See the Software License, Warranty and
Support booklet for more information.
If the port is a mini-GBIC, verify that it is one of the mini-GBICs supported by the switch.
Unsupported mini-GBICs will be identified with this fault condition. The supported
mini-GBICs are listed in Chapter 2, “Installing the Switch” on page 2-18. The
mini-GBICs are also tested when they are “hot-swapped”—installed or changed while
the switch is powered on.
To verify the port has failed, remove and reinstall the mini-GBIC without powering off the
switch. If the port fault indication reoccurs, you will have to replace the mini-GBIC. Check
the event log to see why the mini-GBIC failed.

The network
connection is not
working
properly.
Try the following procedures:
• For the indicated port, verify that both ends of the cabling, at the switch and the
connected device, are connected properly.
• 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 twisted-pair connections to the fixed 10/100 or 10/100/1000 ports, if the port is
configured to “Auto” (auto negotiate), either straight-through or crossover cables
can be used because of the switch’s “Auto-MDIX” feature and the Auto MDI/MDIX feature of the 10/100/1000-T port.
Note: If the switch port configuration is changed to one of the fixed configuration
options (for example, 100 Mbps/Full Duplex), then the port operates as MDI-X only
and you must use the correct type of cable for the connection. In general, for
connecting an end node (MDI port) to the switch, use straight-through cable; for
connecting to MDI-X ports on hubs, other switches, and routers, use crossover
cable.
•
•
•
•
•
4-6
– 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.
For the dual-personality 10/100/1000-T ports, be sure a mini-GBIC is not installed in the
associated slot.
For 1000Base-T connections, verify the network cabling complies with the IEEE 802.3ab
standard. The cable should be installed according to the ANSI/TIA/EIA-568-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 process 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 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 fiberoptic, 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.

The port may be
improperly
configured, or
the port may be in
a “blocking”
state by the
normal operation
of the Spanning
Tree, LACP, or
IGMP features.
Use the switch console to see if the port is part of a dynamic trunk (through the LACP
feature) or to see if Spanning Tree is enabled on the switch, and to see if the port may
have been put into a “blocking” state by those features. The show lacp command displays
the port status for the LACP feature; the show spanning-tree command displays the port
status for Spanning Tree.
Also check the Port Status screen using the show interfaces command to see if the port
has been configured as “disabled”.
Other switch features that may affect the port operation include VLANs and IGMP. Use
the switch console to see how the port is configured for these features.
For software troubleshooting tips, see the chapter “Troubleshooting” in the Management
and Configuration Guide, which is on the ProCurve Web site at www.hp.com/go/
procurve/manuals.
Ensure also, that the device at the other end of the connection is indicating a good link
to the switch. If it is not, the problem may be with the cabling between the devices or the
connectors on the cable.

Proactive Networking
Proactive Networking
The ProCurve 2520G-PoE 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:
■
A graphical Web browser interface 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 you can access by 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.

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. 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.
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 50 seconds. If these LEDs stay on longer than 60
seconds or begin flashing, there may be a problem with the switch.
See “Diagnosing with the LEDs” on page 4-4 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 7, 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
“Configuring the Switch”. Then, when you reset the switch, note the messages that
are displayed. Additionally, you can check the switch event log, which can be
accessed from the console using the show log command, or from the console
Main Menu after entering the Menu command.

Troubleshooting
Hardware Diagnostic Tests
Testing Twisted-Pair Cabling
Network cables that fail to provide a link or provide an unreliable link between
the switch and the connected network device may not be compatible with the
IEEE 802.3 Type 10Base-T, 100Base-TX, or 1000Base-T standards. The twistedpair cables attached to the switch must be compatible with the appropriate
standards. To verify your cable is compatible with these standards, use a
qualified cable test device.
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. For more information, see the Management
and Configuration Guide, which is on the ProCurve Web site at www.hp.com/
go/procurve/manuals.
Testing End-to-End Network Communications
Both the switch and the cabling can be tested by running an end-to-end
communications test—a test that sends known data from one network device
to another through the switch. For example, if you have two PCs on the
network that have LAN adapters between which you can run a link-level test
or Ping test through the switch, you can use this test to verify that the entire
communication path between the two PCs is functioning correctly. See your
LAN adapter documentation for more information on running a link test or
Ping test.

Troubleshooting
Restoring the Factory Default Configuration
Restoring the Factory Default
Configuration
As part of your troubleshooting process on the Switch, it may become
necessary to return the switch configuration to the factory default settings.
This 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 the 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, and stacking. 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. For more information on this command, see
the Management and Configuration Guide, which is on the ProCurve Web
site at www.hp.com/go/procurve/manuals.
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. The power and fault lights come on.
2.
Continue to press the Clear button while releasing the Reset button.
3.
When the Self Test LED begins to flash, release the Clear button.
The switch will then complete its self test and begin operating with 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.

See “Mode Conditioning Patch Cord” on page A-6 for more information.
Note on 1000BASE-T Cable Requirements. The Category 5 networking
cables that work for 100BASE-TX connections should also work for
1000BASE-T, as long as all four-pairs are connected. But, for the most robust
connections, you should use cabling that complies with the Category 5e
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.

Specifications
Mode Conditioning Patch Cord
Mode Conditioning Patch Cord
The following information applies to installations in which multimode fiberoptic cables are connected to a Gigabit-LX port. Multimode cable has a design
characteristic called “Differential Mode Delay”, which requires the
transmission signals be “conditioned” to compensate for the cable design and
thus prevent resulting transmission errors.
Under certain circumstances, depending on the cable used and the lengths of
the cable runs, an external Mode Conditioning Patch Cord may need to be
installed between the Gigabit-LX and the multimode network cable to provide
the transmission conditioning. If you experience a high number of
transmission errors on those ports, usually CRC or FCS errors, you may need
to install one of these patch cords between the fiber-optic port in your switch
and your multimode fiber-optic network cabling, at both ends of the network
link.
The patch cord consists of a short length of single mode fiber cable coupled
to graded-index multimode fiber cable on the transmit side, and only
multimode cable on the receive side. The section of single mode fiber is
connected in such a way that it minimizes the effects of the differential mode
delay in the multimode cable.
Note
Most of the time, if you are using good quality graded-index multimode fiber
cable that adheres to the standards listed in Appendix B, there should not be
a need to use mode conditioning patch cords in your network. This is
especially true if the fiber runs in your network are relatively short.
Installing the Patch Cord
As shown in the illustration below, connect the patch cord to the ProCurve
transceiver with the section of single mode fiber plugged in to the Tx
(transmit) port. Then, connect the other end of the patch cord to your network
cabling patch panel, or directly to the network multimode fiber.
If you connect the patch cord directly to the network cabling, you may need
to install a female-to-female adapter to allow the cables to be connected
together.

patch cord must match the core diameter of the multimode cable
infrastructure (either 50 or 62.5 microns).

Twisted-Pair Cable/Connector Pin-Outs
Twisted-Pair Cable/Connector Pin-Outs
The Auto-MDIX Feature: In the default configuration, “Auto”, the fixed 10/
100/1000Base-T ports on the 2520G-PoE switches all automatically detect the
type of port on the connected device and operate as either an MDI or
MDI-X port, whichever is appropriate. So for any connection, a straightthrough twisted-pair cable can be used—you no longer have to use crossover
cables, although crossover cables can also be used for any of the connections.
(The 10/100/1000-T ports support the IEEE 802.3ab standard, which includes
the “Auto-MDIX” feature.)
If you connect a 2520G-PoE switch twisted-pair port to another switch or hub,
which typically have MDI-X ports, the 2520G-PoE switch port automatically
operates as an MDI port. If you connect it to an end node, such as a server or
PC, which typically have MDI ports, the 2520G-PoE switch port operates as
an MDI-X port. In all cases, you can use standard straight-through cables or
crossover cables.
If you happen to use a correctly wired crossover cable, though, the switch will
still be able to automatically detect the MDI/MDI-X operation and link
correctly to the connected device.
Note
Using Fixed Configurations. If the port configuration is changed to any of
the fixed configurations though, for example 100 Mbps/full duplex, the port
operates as MDI-X only and the correct cable type must be used: for
connections to MDI ports, such as end nodes, use a straight-through cable; for
connections to MDI-X ports, such as on hubs and other switches, use a
crossover cable.
Other Wiring Rules:
A-8
■
All twisted-pair wires used for 10 Mbps, and 100 Mbps operation must be
twisted through the entire length of the cable. The wiring sequence must
conform to EIA/TIA 568-B (not USOC). See “Twisted-Pair Cable Pin
Assignments” later in this appendix for a listing of the signals used on each
pin.
■
For 1000Base-T connections, all four pairs of wires in the cable must be
available for data transmission.
■
For 10 Mbps connections to the ports, you can use Category 3, 4, or 5
unshielded twisted-pair cable, as supported by the IEEE 802.3 Type
10Base-T standard.
Specifications
Twisted-Pair Cable/Connector Pin-Outs
■
For 100 Mbps connections to the ports, use 100-ohm Category 5 UTP or

standard.
■
For 1000 Mbps connections, 100-ohm Category 5e or better cabling is
recommended.
■
To provide Power over Ethernet to the access point, all 4 pairs must be
connected for any network cable attached to this port; the cable must
meet ISO/DIS 11801 Class D requirements and IEEE 802.3af requirements.

switches, you can use straight-through cables.
If any of these ports are given a fixed configuration, for example 100 Mbps/
Full Duplex, the ports operate as MDI-X ports, and straight-through cables
must be then used for connections to PC NICs and other MDI ports.
