Introducing the HP ProCurve Series
2300 and 2500 Switches
The HP ProCurve Series 2300 and 2500 Switches are multiport high-speed
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. With these switches you can directly connect
computers, printers, and servers to provide dedicated bandwidth to those
devices, and you can build a switched network infrastructure by connecting
these switches to hubs, other switches, or routers. In addition, the Series 2500
Switches offer full network management capabilities.
This chapter describes your HP Series 2300 and 2500 Switches including:
■Front and back of the switches
■Features
■Switch operation overview
Throughout this manual, these switches will be abbreviated as the “Series 2300
Switches” and “Series 2500 Switches”, or when common features are being
described, as the “Series 2300 and 2500 Switches”.

LEDs
Table 1-1. Switch LEDs
Switch LEDs State Meaning
Power
(green)
On The switch is receiving power.
Off The switch is NOT receiving power.
Fault
(orange)
Off The normal state; indicates that there are no fault conditions on the switch.
Blinking†A fault has occurred on the switch, one of the switch ports, or the fan. The Status LED
for the component with the fault will blink simultaneously.
On On briefly after the switch is powered on or reset, at the beginning of switch self test.
If this LED is on for a prolonged time, the switch has encountered a fatal hardware
failure, or has failed its self test. See chapter 3, “Troubleshooting” for more information.
Self Test
(green)
Off The normal operational state; the switch is not undergoing self test.
On The switch self test and initialization are in progress after you have power cycled or
reset the switch. The switch is not operational until this LED goes off. The Self Test LED
also comes on briefly when you “hot swap” a transceiver into the switch; the
transceiver is self tested when it is hot swapped.
Blinking†A component of the switch has failed its self test. The status LED for that component,
for example an RJ-45 port, and the switch Fault LED will blink simultaneously.
Mode Select
(3 green LEDs)
Act Indicates that the port Mode LEDs are displaying network activity information.
FDx Indicates that the port Mode LEDs are lit for ports that are in Full Duplex Mode.
Max Indicates that the port Mode LEDs are lit for ports that are operating at their maximum
possible link speed. For the 10/100TX ports, that is 100 Mbps; for any transceivers with
Gigabit capabilities, that is 1000 Mbps.
!Indicates that the port Mode LEDs are displaying network events that could require
operator attention, for example CRC errors or late collisions. See chapter 3,
“Troubleshooting” for more information.
Fan Status
(green)
On The cooling fan is operating normally.
Blinking†The cooling fan has failed. The switch Fault LED will be blinking simultaneously.
†The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.

Introducing the HP ProCurve
Series 2300 and 2500
Table 1-2. Switch and Transceiver Port LEDs
Port LEDs State Meaning
Link On Indicates the port is enabled and receiving a link indication from the connected 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,
or HP TopTools.
Blinking If the LED is blinking simultaneously with the Fault LED, the corresponding port has
failed its self test.
The LED can blink by itself (no Fault LED blinking) for the transceiver ports. This occurs
when a transceiver is installed and the switch has not yet been reset. Transceivers can
be installed in the slots while the switch is powered on, but the switch must be reset
to initialize the transceiver and make it operational.
Mode Displays network activity information, or whether the port is configured for Full Duplex operation, or
maximum link speed operation, or is experiencing network events requiring operator intervention
depending on the mode selected. See “Mode Select Button and Indicator LEDs”below for more
information.

Introducing the HP ProCurve
Series 2300 and 2500
Mode LED Select Button and Indicator LEDs
To optimize the amount of information that can be displayed for each of the
switch ports without overwhelming you with LEDs, the Series 2300 and 2500
switches use a Mode LED for each port. The operation of this LED is controlled
by the Mode LED Select button, and the current setting is indicated by the
Mode LED Select indicator LEDs near the button. Press the button to step
from one mode to the next.
■If the Activity (Act) indicator LED is lit, each Mode LED displays activity
information for the associated port—it flickers as network traffic is
received and transmitted through the port.
■If the Full Duplex (FDx) indicator LED is lit, the Mode LEDs light for those
ports that are operating in full duplex.
■If the maximum speed (Max) indicator LED is lit, the Mode LEDs light for
those ports that are operating at their maximum possible link speed: 100
Mbps for 10/100 ports and 100-FX fiber-optic ports, and 1000 Mbps for
100/1000Base-T or gigabit fiber-optic ports.

Console Port (Series 2500 Switches only)
This port is available on the Series 2500 switches, and is used to connect a
console to the switch by using the serial cable supplied with the switch. This
connection is described under “Connect a Console to the Switch”in chapter
2, “Installing the Switches”. The console can be a PC or workstation running
a VT-100 terminal emulator, or a VT-100 terminal.
Download Port (Series 2300 Switches only)
This port is available on the Series 2300 switches, and is used to connect a PC
to the switch by using any “null modem”cable. This connection is described
under “Connect a Console to the Switch”in chapter 2, “Installing the
Switches”. The PC can then be used to initiate a download of new code to the
Series 2300 switch. New code may be made available if there are any product
enhancements, for example to support new transceivers. (For the Series 2500
switches, you can download new code through the Console port.)
For the procedures to download new code to your Series 2300 switch, please
see “Downloading New Code (Series 2300 Switch)”on page 3-12.
Reset Button
This button is used to reset the switch while it is powered on. This action clears
any temporary error conditions that may have occurred and executes the
switch self test. Press the Reset button also after installing any transceivers
while the switch is powered on. After installing the transceiver, the switch
must be reset to initialize the transceiver and make it operational.
For the Series 2500 switches, this button also resets all network activity
counters to zero. The counters are displayed in the Series 2500 switch console
interface, the web browser interface, and through SNMP network manage-
ment applications, such as HP TopTools for Hubs & Switches.

Clear Button (Series 2500 only)
This button is used for these purposes:
■Deleting Passwords - When pressed by itself for at least one second, the
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, any configuration changes you may
have made through the switch console, the web browser interface, and
SNMP management are removed, and the factory default configuration is
restored to the switch. For the specific method to restore the factory
default configuration, see “Restoring the Factory Default Configuration”
in chapter 3, “Troubleshooting”of this manual.

Power Connector
The Switch 2300 and Switch 2500 models do not have a power switch; they
are powered on when connected to an active AC power source. The switches
automatically adjust to any voltage between 100-127 and 200-240 volts and
either 50 or 60 Hz. There are no voltage range settings required.

Switch Features
Introducing the HP ProCurve
Series 2300 and 2500
Switch Features
The features of the Series 2300 and 2500 switches include:
■12 or 24 autosensing 10/100Base-TX RJ-45 ports with Auto MDI/MDI-X.
■two slots for installing supported gigabit or 100Base-FX transceivers.
■plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.
■HP Auto-MDIX on all 10/100 twisted-pair ports, and IEEE 802.3ab Auto
MDI /MDI-X on all 100/1000 twisted-pair ports, meaning that all connec-
tions can be made using straight-through twisted-pair cables.
Cross-over cables are not required, although they will also work. The pin
operation of each port is automatically adjusted for the attached device:
if the switch detects that another switch or hub is connected to the port,
it configures the port as MDI; if the switch detects that an end-node device
is connected to the port, it configures the port as MDI-X.
■automatic learning of the network addresses in each switch’s 4096-
address forwarding table, (with configurable address aging value in the
Series 2500 switches).
■automatically negotiated full-duplex operation for the fixed 10/100 RJ-45
ports when connected to other auto-negotiating devices —the transceiver
ports always operate at full duplex.
■the Series 2300 switches have a Download Port, through which you can
update your switch with the latest code, for any product enhancements
or bug fixes. (For the Series 2500 switches, you can download new code
through the Console port.)
The Series 2500 switches also include these network management features:
■easy management of the switches through several available interfaces:
•web browser interface—an easy to use built-in graphical interface
that can be accessed from common web browsers.
•console interface—a full featured, easy to use, VT-100 terminal
interface that is especially good for out-of-band switch management
or for telnet access to the switch.
•HP TopTools for Hubs & Switches—an SNMP-based, graphical
network management tool that you can use to manage your entire
network. This product is included with your new switch.
■support for the Spanning Tree Protocol to eliminate network loops

Switch Operation Overview
Address Table Operation
Address Learning. As devices are connected to the switch ports, either
directly or through hubs or other switches, the MAC addresses of those
devices are learned automatically and stored in the 4096-entry address table
featured by the Series 2300 and 2500 switches. The switches also identify the
number of the port on which each address is learned so they know the network
location of each connected device.
Forwarding, Filtering, Flooding. When the switch receives a packet, it
determines the destination address and looks for the address in the address
table. Based on the port location of that address, the switch then determines
whether to forward, filter-out, or flood the packet.
■forward - if the destination address is on a different port than the one on
which the packet was received, the packet is forwarded to the destination
port and on to the destination device.
■filter out - if the destination address is on the same port as the one on
which the packet was received, the packet is filtered out. The switch
thereby isolates local traffic so the rest of the network connected to the
switch does not lose bandwidth dealing with unnecessary traffic.
■flood - whenever a new destination address is found in a packet received
on a switch port, the destination address will not yet be in the switch’s
address table and the switch cannot know whether to forward or filter out
the packet. In this case, it sends the packet to all the other switch ports.
This is referred to as “flooding”. When the destination device receives the
packet, and it replies, the switch learns the new address from the reply
packet. Then, all future packets destined for that address are forwarded
or filtered out appropriately.
Note: Usually, multicast and broadcast packets are flooded, although
configuration of sofware features influence that behavior.

Network Moves and Changes. When a PC, server, printer, or other
network device is moved in the network, and becomes connected to a different
switch port, the Series 2300 and 2500 switches automatically recognize the
change and update their address table with the new port location of the device.
Communication with the device is automatically maintained, without any
address table manipulation being required by the network administrator.
Effect of VLANs (Series 2500 only)
On the Series 2500 switches, if you configure multiple virtual LANs (VLANs)
on the switch, each VLAN behaves as a “logical switch”containing the switch
ports that you assign to it. Each logical switch behaves as an isolated broad-
cast domain, just as if it were a separate physical switch. The forward, filter,
and flood behavior described for the physical switch above, operates the same
for each of the logical switches defined by the VLANs: packets are forwarded
or flooded only to the ports that are within a given VLAN. Just as for separate
isolated physical switches, there is no communication between ports that are
in separate VLANs unless the VLANs are connected by an external router.
For more information on configuring VLANs and their behavior, see the
Management and Configuration Guide that came with your switch.

and 2500 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 2-4). Make sure that the physical
environment into which you will be installing the switch is properly
prepared, including having the correct network cabling ready to connect
to the switch and having an appropriate location for the switch. Please see
page 2-3 for some installation precautions.
2. Install transceivers (optional—page 2-6).The switches have two
slots for installing any of the supported HP Gbps (gigabit) or 100 Mbps
transceivers. Depending on where you will install the switch, it may be
easier to install the transceivers first.
3. Verify that the switch passes self test (page 2-7). This is a simple
process of plugging the switch into a power source and observing that the
LEDs on the switch’s front panel indicate correct switch operation.
4. Mount the switch (page 2-9). The Series 2300 and 2500 switches can
be mounted in a 19-inch telco rack, in an equipment cabinet, on a wall, or
on a horizontal surface. The included mounting brackets allow mounting
the switch in a variety of locations and orientations.
5. Connect power to the switch (page 2-13). Once the switch is
mounted, plug it in to the nearby main power source.
6. Connect the network devices (page 2-14). Using the appropriate
network cables, connect the network devices to the switch ports.
7. Connect a console to the switch (optional, on Series 2500 switches
only—page 2-15). For your Series 2500 switch, 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 manage-
ment station, or through a Telnet session. Configuration changes can be
made easily by using the included console cable to connect a PC to the
switch’s console port.
At this point, your switch is fully installed. See the rest of this chapter if you
need more detailed information on any of these installation steps.
