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.

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.

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.

Installation Procedures

Installing the Series 2300

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.
