HP ProCurve Switch 2424M
Gigabit Stacking Module
Description
The HP ProCurve Switch 2424M Gigabit Stacking Module is a component that
you can add to an HP ProCurve Switch 2424M to provide stacking between
Switch 2424Ms and a variety of other network connectivity options.
Features: The HP Gigabit Stacking Module has the following features:
■two transceiver slots for installing any of the HP ProCurve Gigabit trans-
ceivers:
• Gigabit-SX Transceiver (HP J4131A)
• Gigabit-LX Transceiver (HP J4132A)
• Gigabit Stacking Transceiver
(part of the Gigabit Stacking Kit—HP J4116A)
■auto-enabled ports—the ports are all configured to be ready for network
operation as soon as a viable network cable is connected
■auto-configuration—a default configuration is applied to the module when
the switch is powered on and the module passes self test; this default
configuration works well for most network installations
■LEDs that provide information on the link status, network activity, connec-
tion speed, and communication mode (half or full duplex)
■“hot swap” operation—you can add a module or replace a module without
having to shut down the switch (changing the module type in a given slot
does require a switch reset)

Installing the Module
Installing the Module
Overview
You can install the Gigabit Stacking Module into only the HP ProCurve Switch
2424M. The installation steps are:
1. Verify that your HP ProCurve Switch 2424M has the correct operating
system software (OS) version. Switch 2424M units that were shipped
before the Gigabit Stacking Module became available may be running
software that does not support the module. The switch must be running
OS version C.06.06 or later to support the Gigabit Stacking Module (see
page 3).
Install new software, if needed. The new software is found on the floppy
disk included with the module. You can also copy the OS file from the HP
networking products world wide web site:
http://www.hp.com/go/procurve
The software files to download are located under the [Support] button on that
web page.
2. Install transceivers into the module transceiver slots (see page 5).
3. Install the module in the Switch 2424M slot (see page 6).
4. Verify that the module is installed correctly (see page 7).
5. Connect the network cabling (see page 8).
6. Reset the switch, if you have installed the module into a slot that was
previously occupied by a different type module (see page 10).
7. Optionally, customize the configuration for the module’s ports (unless the
default port configuration is satisfactory for your network environment -
see page 11).
Note If necessary, you can “hot-swap” one module for another; that is, replace one
module with another of the same type while the switch is still powered on,
without interrupting the operation of the rest of the switch ports. You can also
install the module into the unused switch slot without interrupting the switch
operation. For more information, see page 16.

Installing the Module
1. Download Switch Software
Verify Current Switch Software
Your HP ProCurve Switch 2424M must be running OS version C.06.06 or later
to support the Gigabit Stacking Module. To determine which OS version is
running in the switch, connect a console to the switch and perform the
following (see the switch Installation Guide for more information about
connecting a console and using the console interface):
1. From the console Main Menu, press [1] to select Status and Counters... to
display the Status and Counters menu.
2. Press [1] again to select General System Information ... to display the Switch
Information screen, as shown in the next figure.
3. Check the “Firmware revision” line.
• If the revision number is C.06.06 or later, the switch can support the
Gigabit Stacking Module, and you do not need to download new soft-
ware to the switch. In this case, go to “Installing Transceivers in the
Module” on page 6.
• If the revision number is earlier than C.06.06, download the new soft-
ware before installing the Gigabit Stacking Module. In this case,
continue with the instructions in this section before you install the
module.

Installing the Module
Download the New OS Software
This procedure describes how to use a personal computer (PC) to download
the software. If you are using a UNIX workstation, refer to the Note at the
bottom of this page.
For more details on the download process, see the Management and Config-
uration Guide you received with your switch.
Note TFTP Download from UNIX: To perform a TFTP download from a UNIX
system, store the OS file,
filename .swi, in the UNIX TFTP directory, then
perform the TFTP download as described in the switch Management and
Configuration Guide.
1. Do one of the following:
• If the source of your software file is the disk shipped with the Gigabit Stacking Module, copy
the file from the disk into the PC directory you will use for downloading to the switch, or
you can download it directly from the floppy disk. Go on to step 2.
• If the source of your software file is the self-extracting file from the HP ProCurve web page
(http://www.hp.com/go/procurve), do the following:
a. Copy the self-extracting file into the directory you will use for downloading to the switch.
b. Execute the file to decompress and extract its contents.
2. Download the software upgrade to your HP ProCurve Switch 2424M. The download is executed
from the switch console, by selecting Download OS from the console Main Menu.
a. On the Download OS screen, select the file transfer method, TFTP or Xmodem:
–UsetheTFTP method to transfer the file over the network. The OS file must be copied
to a TFTP server, and the switch must have been configured with an IP address and must
have network access to the TFTP server.
–UsetheXmodem method to transfer the file serially (the network does not need to be
operating). The OS file must be copied to a PC that can be serially connected to the switch
console port (use the console cable supplied with the switch). The PC must have a
terminal program that supports the Xmodem transfer protocol.
b. Then, for the Remote File Name parameter, use the form:
filename .swi (for example, C_06_06.swi)
3. When the download is complete, proceed to “2. Install Transceivers Into the Module” on page 5.

Installing the Module
2. Install Transceivers Into the Module
Any of the HP Gigabit Transceivers (Gigabit-SX, Gigabit-LX, or Gigabit
Stacking) can be installed in either of the transceiver slots in the Gigabit
Stacking Module. The order or location does not matter.
To install the transceivers, follow these steps:
1. Using a Torx T-10 or flat-bladed screw driver, remove the transceiver slot
cover. Keep the cover for future use. It does not matter which transceiver
slot is used first, 1 or 2.
2. Hold the transceiver by the bulkhead and slide the transceiver all the way
into the slot until it “snaps” into place. The transceiver bulkhead should be
touching the face of the module.
3. Tighten the retaining screws on the transceiver until they are secure, but
be careful to not overtighten these screws.
For more detailed information on installing the transceivers, see the Installa-
tion Guide that came with the transceiver.
Installation Precautions:
■Static electricity can severely damage the electronic components on the module and on trans-
ceivers you install into the module. When handling the module and transceivers and installing
them in your switch, follow these procedures to avoid damage from static electricity:
• Handle the module and transceivers by their bulkheads or edges and avoid touching the
components and the circuitry on the boards.
• When installing the module and transceivers, equalize any static charge difference between
your body and the switch by wearing a grounding wrist strap and attaching it to the switch’s
metal body, or by frequently touching the switch’s metal body.
■For proper switch cooling and reduction of electromagnetic emissions, ensure that a slot cover
is installed on any unused module or transceiver slot.
■An incompletely installed module will temporarily disrupt switch operation and
prevent the module from operating. Make sure the module is fully installed and that
you screw in the retaining screws to secure the module in place.
■Before installing the Gigabit Stacking Module into the switch, you should first install all
transceivers into the module. The transceivers can not be “hot swapped”. They must be
installed when the module is not receiving power, either by first removing the module from the
switch, or by powering off the switch.

Installing the Module
3. Install the Module
1. Use a Torx T-10 or flat-bladed screwdriver to unscrew the screws in the
module slot cover plate in the back of the Switch 2424M. Then remove the
cover plate and store it for possible future use.
2. Hold the module by its bulkhead, taking care not to touch the metal
connectors or components on the board. Orient the module as shown in
the illustration below.
3. Rotate the lever handle fully outward, and then insert the module into the
slot guides and slide it into the slot until it stops.
4. Make sure the two retaining screws are aligned with the holes in the switch,
then rotate the lever handle inward as far as it will go to pull the module
into the switch connectors. The module bulkhead should be in contact with
the face of the switch.

Installing the Module
5. Tighten the two retaining screws to hold the module in place. The retaining
screws should be secure but be careful to not overtighten them.
4. Verify the Module is Installed Correctly
Observe the Module Status, Self Test, and Fault LEDs on the front of the switch
to verify that the module is installed properly.
When the module is installed properly and the switch is powered on, or the
module is installed when the switch already has power, the module undergoes
a self test that takes a few seconds. You can use the LEDs to determine that
the module is installed properly and has passed the self test, as described in
the “LED Behavior” table below.

Installing the Module
If the Module Status, Self Test, and Fault LEDs are flashing, the
module may not be completely installed. Make sure the module is
installed all the way into the switch slot. If the flashing continues,
see the Troubleshooting section on page 13.
5. Connect the Network Cables
1. Connect the appropriate network cables to the module’s transceiver ports.
The table below shows the supported cable types for each of the trans-
ceivers.
Supported Cable Types.
Port Type Cable Type Length Limits
Gigabit-SX 62.5/125 µm or 50/125 µm core/cladding

Installing the Module
2. Check the port LEDs for the newly-installed module to ensure that the
port(s) connected in the preceding step are operating correctly. For each
of the two transceiver ports on the switch module there are Link and Mode
LEDs as shown in the next illustration.
Example Link and Mode LEDs
• The Link LED will be lit for each port that is connected properly to an
active network device.
If the Link LED does not go on when an active network cable is
connected to the port, there may be something wrong with the cable,
the cable connectors, or the device at the other end of the cable. See
the troubleshooting information on page 13.
• If the switch Mode is set to display activity (the [Act] mode indicator LED
is lit), then the Mode LED for each port that is transmitting and/or
receiving packets will flicker when traffic is detected on the port.
• If the Mode is set to display full duplex (the [Fdx] mode indicator LED is
lit), then the Mode LED will be lit for each port that is operating in full
duplex.
• If the Mode is set to display 100 Mbps operation (the [100] mode indicator
LED is lit), then the Mode LED will be lit for each port that is operating
at 100 Mbps. Since the Gigabit Transceivers operate at
1 Gbps, the [100] Mode LED should not light for these ports.
For examples of connections using the Gigabit Stacking Module, see “Sample
Connections” on page 12.

Installing the Module
6. Reset the Switch (if necessary)
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—for example, installing a Gigabit Stacking Module in a slot
that was previously used for a Gigabit-LX 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 correctly. The Module Status LED on the front
of the Switch 2424M will continue to flash, 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.)
■For diagnostic purposes. See “Troubleshooting” on page 13 for more
information.
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
■changing most of the switch configuration parameters
Methods of Resetting the Switch
You can reset the switch by any of these methods:
■pressing the Reset button on the front of the switch
■power cycling the switch
■selecting the Reset or Reboot option from the switch console, web browser
interface, or HP TopTools for Hubs & Switches

11
Installing the Module
7. Customize the Port Configuration (Optional)
If the module slot in the Switch 2424M was empty the last time the switch was
either rebooted or reset (or the power to the switch was cycled), then the
module will use preconfigured default parameter values that will work for
most networks.
The default port configuration for the module is:
■Ports Enabled: Yes
■Mode:
• Gigabit-SX and Gigabit-LX Transceivers — 1000FDx (1000 Mbps, Full
Duplex)
• Gigabit Stacking Transceiver — Auto (auto negotiates flow control if
flow control is enabled for the port)
■Trunk (port trunking): None
■Switch Mesh: Not a member
■Broadcast Limit: 0(no broadcast limiting)
■Flow Control: Disabled
■Spanning Tree: Disabled
■IGMP: Disabled
■Traffic Filters: None (the switch performs its filtering and forwarding
only according to standard address table operation)
If necessary, configure the port(s) in the module by using the switch console
or the web browser interface. For more information, see the Management and
Configuration Guide shipped with the switch, and the online Help provided
in the console and web browser interface.
If the default port configuration listed above is acceptable for your network,
then skip this process.

Troubleshooting
Troubleshooting
The primary tools for troubleshooting the switch modules are the LEDs on the
front of the switch and on the module. Refer to “LED Behavior” on page 7.
Also, refer to the Installation Guide and the Management and Configuration
Guide shipped with the switch, for more detailed troubleshooting informa-
tion.
The following tables describe switch and module LED displays that indicate
that the module or connections to the ports on the module are not operating
correctly.

Tip
Number Problem Solution
➊The module is not
installedproperly
in the slot or has
become partly
removed during
switch operation.
Under this error condition, the following events also occur:
• All the LEDs on the module stay on until the error is resolved.
• The switch software, including console and web browser access will not be
operational for approximately one minute from the time the module gets into this
condition.
Make sure to screw in the retaining screws to firmly position the module and so that
the module cannot be inadvertently pulled out by pulling on the network cables.
If this does not resolve the condition, try reinstalling the module. You can do this without
having to power down the switch.

Troubleshooting
➋The module was
installed in the
slot after a
different type
module was
previously
installed, and the
switch has not
yet been reset.
When you “hot swap” modules in the switch slot, if you install a different module type
than the one that was previously installed in the slot, you must reset the switch so the
switch processor can properly initialize and configure the new module type. The
flashing LED informs you that this change of module types has occurred. The module
will not work properly until the switch is reset as indicated by all the module’s LEDs
staying on until the switch is reset.
See “Reset the Switch” on page 10.
➌The module has
experienced a
self test fault.
The module and transceivers are tested whenever the switch is powered on, or reset
(through the Reset button on the switch, or the Reboot or Reset options in the console
or web browser interface). When the module is hot swapped (installed when the switch
is powered on), the self test is a partial test that may not detect all possible module
failures and does not detect transceiver failures.
Try the following procedures to resolve this condition:
• Remove and reinstall the module. You can do this without having to power down the
switch. When the module is reinstalled, it will be retested automatically.
• If this does not resolve the condition, try resetting the switch. See “Reset the
Switch” on page 10. A more thorough test is performed when the switch is reset or
power cycled.
If the same fault indication reoccurs or a new fault indication results from the switch
reset, see tip ➍below.
➍The module or
one of the
transceivers has
experienced a
self test fault.
The self test that is performed after the switch is powered on or reset is a complete
test of both the module and the transceivers.
If ONE set of module port LEDs (Link and Mode LEDs for one of the ports) stays on, the
faulty unit is probably the transceiver associated with the LEDs that are on. Try these
procedures:
1. Remove the module from the switch.
2. Remove the suspected transceiver from the module.
3. Reinstall the module and reset the switch. See “Reset the Switch” on page 10.
• If the self test is successful, the transceiver is faulty and must be replaced.
• If the self test still fails, the module is faulty and must be replaced.
If both sets of port LEDs stay on, the faulty unit is probably the module. Try these
procedures:
1. Remove the module from the switch.
2. Remove both of the transceivers.
3. Reinstall the module and reset the switch.
• If the self test is successful, both of the transceivers are faulty and must be
replaced.
• If the self test still fails, the module is faulty and must be replaced.
