Installing the Module
Installing the Module
Overview
You can install any of the modules into any of the HP ProCurve switches that
have a compatible module slot. The installation steps are:
1. For the Gigabit-LX Module or 100/1000Base-T Module, download
the new OS code to your HP ProCurve switch. The switch must be running
OS version C.05.06 or later to support the Gigabit-LX Module and version
C.07.27 or later to support the “B” model of the 100/1000Base-T Module
(HP J4115B) (see page 4). The new code 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 can be accessed by clicking on Technical
Support on that web page.
2. Install the module in a switch slot (see page 6).
3. Verify that the module is installed correctly (see page 8).
4. Connect the network cabling (see page 9).
5. Optionally, customize the configuration for the module’s ports (unless the
default port configuration is satisfactory for your network application -
see page 15).
6. Reset the switch, if you have installed the module into a slot that was
previously occupied by a different type module (see page 17).
Note If necessary, you can “hot-swap” one module for another; that is, replace one
module with another while the switch is still powered on, without interrupting
the operation of the rest of the switch ports. For more information, see page 16.

Installing the Module
Downloading Switch Software
Verifying Current Switch Software
Most of the HP ProCurve Switch Modules are supported by all versions of the
switch operating system (OS). For two of the modules, your HP ProCurve
Switch must be running specific OS versions:
■Gigabit-LX Module (HP J4114A) - OS version C.05.06 or later
■100/1000Base-T Module (HP J4115B) - OS version C.07.27 or later
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 inter-
face):
1. From the console Main Menu, select Status and Counters... to display the
Status and Counters menu.
2. Select General System Information... to display the Switch Information
screen, as shown in the next figure.
3. Check the “Firmware Revision” line.
• If the OS version number is C.05.06 or later, the switch can support the
Gigabit-LX Module; if the version is C.07.27 or later, the switch can
support the 100/1000Base-T Module (“B” model), and you do not need
to download new software to the switch. In this case, go to “Installing
the Module in an Unused Slot” on page 6.
• If the version number is earlier than the required version, download the
new OS, as described on the next page, before installing the module.
OS Version information

Installing the Module
Downloading the New OS
This procedure describes how to use a personal computer (PC) to download
the OS. If you are using a UNIX workstation, refer to the Note at the bottom
of this page.
1. Do one of the following:
• If the source of your OS file is the disk shipped with the Gigabit-LX
or 100/1000Base-T 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 OS files is the self-extracting file from an
electronic source (for example, the web), 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.
c. Go on to step 2.
2. Download the software upgrade to your HP ProCurve switch.
The download is executed from the switch console, by selecting Download
OS from the console Main Menu.
On the Download OS screen, select the file transfer method, TFTP or
Xmodem. Then, for the Remote File Name parameter, use the form:
filename.swi (for example, C_07_27.swi)
For details on the download process, see the Management and Configu-
ration Guide you received with your switch.
3. When the download is complete, proceed to “Installing the Module in an
Unused Slot” on page 6.
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.

Installing the Module
Installing the Module in an Unused Slot
1. Use a Torx T-10 or flat-bladed screwdriver to unscrew the screws in the
cover plate over the slot you want to use, and remove the cover. Store the
cover plate 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 so the slot
letter on the switch face can be seen through the slot identification
window on the module when the module is installed.
3. Insert the module into the slot guides and slide it into the slot until it stops.
Then press the module in firmly until it “snaps” into place. The module
bulkhead should be in contact with the face of the switch.
Note: As shown in the illustrations on the next page, the switch may have
either vertical or horizontal module slots. In all switches, the modules can
be installed in only the orientation that allows the slot identification letter
on the switch to be viewed through the slot identification window on the
module.
Installation Precautions:
■Static electricity can severely damage the electronic components on the modules. When
handling and installing the modules in your switch, follow these procedures to avoid damage
from static electricity:
• Handle the module by its bulkhead or edges and avoid touching the components and the
circuitry on the board.
• When installing the module, 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.
■Make sure that when installing a module that you use some caution to slide the module past
the initial contact with the RFI fingers on the switch chassis or on adjacent modules or
bulkheads before applying strong installation force. It is possible to dislodge the RFI fingers on
an adjacent module or bulkhead if the module you are installing is “biased” toward the fingers
and strong installation force is applied before the module you are installing has passed the initial
contact with the RFI fingers. The RFI fingers are identified in one of the illustrations on the
next page. If the RFI fingers are dislodged, make sure to unplug the switch, remove the RFI
fingers from the switch chassis, and reinstall them before powering on the switch.
■For proper switch cooling and reduction of electromagnetic emissions, ensure that a slot cover
is installed on any unused module slot.
■An incompletely installed module will temporarily disrupt switch operation and
prevent the module from operating. Make sure all modules are fully installed and
that you screw in the retaining screws to secure the module in place.

Installing the Module
Note: Use some caution when installing modules. Excessive installation force
could cause the RFI fingers on the switch or adjacent module or bulkhead to
be dislodged. Please see the “Installation Precautions” on the previous page.

Installing the Module
4. Verify the module is installed correctly. Observe the Module Status LED
for the slot in which the module is being installed, and the Self Test and
Fault LEDs on 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.
LED Behavior
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 18.

Note: If the switch was powered off while the module was
installed, when the switch is powered on, the Self Test LED will
stay ON for the duration of the whole switch self test.
Fault OFF

Installing the Module
5. Tighten the two retaining screws with a flat-blade or Torx T-10 screwdriver
to secure the module in the slot. Be careful not to overtighten the screws.
6. Connect the appropriate network cables to the module's ports as shown
in the table on the next two pages. The table shows the supported cable
types for each of the modules. For more information on the cable speci-
fications, see “Cables” on page 22.
Note “Auto MDI/MDI-X” with the 100/1000Base-T Module:
When the 100/1000Base-T Module is in the default configuration, Auto, the
module automatically negotiates whether the port operates as MDI or MDI-X,
depending on the cable type and the connected device’s operation. As a result,
any connection to either another Gigabit device or to a 100Base-T
device can be made using a straight-through cable. You never have to use
a crossover cable, but a crossover cable may also be used if you choose. Either
a straight-through or crossover cable will work correctly.
If, however, the configuration is changed to one of the 100 Mbps fixed options
(100-Half Duplex or 100-Full Duplex), the port operates as an MDI-X port. In
that case, to connect the module to another switch or hub, use a crossover
cable; to connect to an end node, use a straight-through cable.

or hub, use a crossover cable; for connecting these to an end node, use a straight-through cable.
• Since the 10Base-T connections are through 10/100Base-T ports, if you ever want to upgrade the connections to
100Base-T operation, it would be best to cable the connections initially with category 5 cable.

Installing the Module
7. Check the port LEDs for the newly-installed module to ensure that the
port(s) connected in the preceding step are operating correctly. Each port
on the switch modules has Link and Mode LEDs near it 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 18.
•If the switch Mode is set to display activity (the
 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
 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
 mode
indicator LED is lit), then the Mode LED will be lit for each port that
is operating at 100 Mbps. Note that for ports operating at 1000 Mbps
(Gigabit), the Mode LED will not be lit.
8. Customize the port configuration, if necessary. (See “Customizing the Port
Configuration”on page 15.)
9. Reset the switch, if you have installed a module in place of a different type
of module. (See “Resetting the Switch”on page 17 for more information
on when the switch must be reset.)

Installing the Module
Mode Conditioning Patch Cord for Gigabit-LX
The following information applies to installations in which multimode
fiber-optic cables are connected to a Gigabit-LX Module installed in the
switch.
Unlike Gigabit-SX, which connects to only multimode fiber-optic cabling,
Gigabit-LX can use either single mode or multimode cable. Multimode cable
has a design characteristic called “Differential Mode Delay”, which requires
that the transmission signals be “conditioned”to compensate for the cable
design and thus prevent resulting transmission errors. Since Gigabit-SX is
designed to operate only with multimode cable, Gigabit-SX transceivers can
provide that transmission conditioning internally.
Gigabit-LX transceivers, since they are designed to operate with both single
mode and multimode cable, do not provide the transmission conditioning
internally. Thus, 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 transmitting device
and the multimode network cable to provide the transmission conditioning.
If you experience a high number of transmission errors on the Gigabit-LX
ports, usually CRC or FCS errors, you may need to install one of these patch
cords between the Gigabit-LX Module installed in your switch and your
multimode fiber-optic network cabling, and between the Gigabit-LX trans-
mission device and the network cabling at the other end of the multimode
fiber-optic cable run. A patch cord must be installed at both ends.
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 multi-
mode 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 on page 22, 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.
If you are using single mode fiber-optic cabling in your network, there is no
need to use mode conditioning patch cords. Connect the single mode network
cable directly to the Gigabit-LX Module.
2347.book Page 13 Tuesday, May 9, 2000 12:53 PM

14
Installing the Module
Installing the Patch Cord
As shown in the illustration below, connect the patch cord to the Gigabit-LX
Module 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.
Make sure you purchase a patch cord that has SC connectors on the end that
connects to the Gigabit-LX module and has multimode fibers that match the
characteristics of the multimode fiber in your network.
Recommended Patch Cords
The following Mode Conditioning Patch Cords have been tested and verified
to operate correctly with the HP ProCurve Switch Gigabit-LX Module:
These part numbers could change. Contact Computer Crafts through the
