Installation Notes
Please read these notes before proceeding.
■The illustrations in this document show the transceivers being used
a small number of the HP networking devices that are designed to
accept them. But, the procedures pertain to using these transceivers
in all the HP networking devices that accept them.
The HP ProCurve High-Speed Transceivers are supported in the HP
ProCurve networking devices as shown in the following table:
Switch 2424M Gigabit
Stacking Module*
Series 2300 and 2500
Switches
Gigabit-SX Transceiver supported supported
Gigabit-LX Transceiver supported supported
100/1000-T Transceiver NOT supported supported
100-FX SC Transceiver NOT supported supported
■For all of the networking devices that support the HP ProCurve High-
Speed Transceivers, it is not necessary to turn off power to the device
before installing the transceiver into it:
• For the Switch 2424M Gigabit Stacking Module*, you can leave
the power on to the switch, but remove the module from the
switch before installing transceivers into it. Reinstalling the
module into the switch initializes and activates the transceivers.
• For the Series 2300 and 2500 switches, you can install the trans-
ceivers while the switches are powered on, but you must reset or
reboot the switch after installing the transceiver to initialize and
activate it.
• For other HP ProCurve network devices, the transceivers may be
fully “hot swappable”—you can install or remove them at any time
without having to remove power from the device and without
having to reset the device.
Please see the installation guide for the networking device for more
information on installing the transceivers.
*The Switch 2424M Gigabit Stacking Module (J4130A) provides trans-
ceiver connectivity only for an HP ProCurve Switch 2424M (J4093A).

Installation Steps
To install the HP ProCurve High-Speed Transceivers, follow these steps:
1. Insert the transceiver into an HP networking device's transceiver slot
and secure the retaining screws.
2. If the transceiver slot is in a module, install the module into the switch.
3. As necessary for the type of networking device into which the trans-
ceivers are installed, reset or reboot device.
4. Connect the network cable to the transceiver and check the transceiver
and network device for correct operation.
Details on these steps are provided in the rest of this document.
Insert the Transceiver Into the Slot
The transceivers are installed into an HP networking device, as follows:
1. If you are installing the transceiver into the HP ProCurve 2424M Gigabit
Stacking Module, first remove the module from the switch. Then, for
that module and for all other networking devices, using a flat-bladed or
Torx T-10 screwdriver, unscrew the two retaining screws on the slot
cover plate or existing transceiver, and remove it from the module or
device.
2. Touch a grounded, metal object (such as a powered-on switch) to
discharge any static electricity on your body, then carefully remove the
transceiver from its protective anti-static packaging. Hold the trans-
ceiver by its bulkhead or edges, taking care not touch any of its board
components or metal connectors.

3. Slide the transceiver firmly into the transceiver slot as far as it will go.
The transceiver will “snap” into place, and the transceiver's faceplate
should touch the face of the device. The following illustration shows
the transceiver being installed in an HP ProCurve Switch 2524.
4. Using the flat-bladed or Torx T-10 screwdriver, tighten the retaining
screws on the transceiver until they are secure, but be careful that you
do not overtighten the screws.
5. If the transceiver is installed in a Gigabit Stacking Module, reinstall the
module into the switch and make sure the switch is powered on, or if
the transceiver is installed directly into a switch, reset the switch, if
necessary, to initialize the transceivers. Please see the Installation Notes
on page 2 for information about initializing the transceivers in different
HP ProCurve networking devices.

To connect a fiber-optic cable to
a transceiver:
1. For fiber-optic transceivers,
remove the plastic dust covers
from the cable connectors and
from the transceiver port.
2. Press the connector into the jack
so that the tabs on the connector
slide into the notches in the jack
and the connector snaps securely
into place.
3. If you are using cable with SC duplex connectors, as shown in the
illustration, both cables are connected simultaneously. If the cable has
simplex connectors, install them one at a time and make sure that the
cable connected into the Tx (transmit) port on the transceiver is
connected into the receive port on the device at the other end of the
cable; similarly, make sure the Rx (receive) port on the transceiver is
connected to the transmit port on the other device.
To connect a twisted-pair cable
to a transceiver:
Push the RJ-45 plug into the RJ-45
jack until the tab on the plug clicks
into place.
When power is applied to this transceiver
and an active network cable is connected to
the transceiver port, the Link LED for the
port should be ON.
If the LED is off, see “Troubleshooting”, on
the next page.

Troubleshooting
The following problems may exist:
■The Link LED for the transceiver is not on, even though the transceiver
is receiving power and the network cable is connected. Check the
following:
• Verify that the networked device at the other end of the cable is on.
• Verify that the cables are connected correctly to the transceiver ports. See
step 3 in the installation instructions.
• Verify that the cable length does not exceed the maximum distances listed
on page 4.
• Check all cabling and connections (including patch panels) to make sure
that all connections are secure, no connectors are damaged, and that none
of the connectors have a dust buildup or other object in the way that may
cause interference to the light transmission or electrical connections. If all
connections are OK, try a different cable.
• Verify that the networked device connected to the transceiver is the correct
type for the transceiver used.
• Verify that the transceiver is supported by the switch or module into which
you are installing it. See the table on page 2 to identify which transceivers
are supported by which network devices.
• Try resetting or cycling power (turn the power off and then back on) on
the networking device in which the transceivers are installed. If the trans-
ceiver is being used in a Gigabit Stacking Module and the module has been
“hot swapped” into the Switch 2424M, the resulting self test does not test
the transceivers. Resetting the switch causes a complete self test to be
performed, which does test the transceivers.
■The switch Link LED for the transceiver port is blinking. This
condition occurs on the Series 2300 and 2500 switches. After installing the
transceiver, these switches must be reset or rebooted to initialize the
transceiver. The flashing LED tells you that the transceiver is not operational
until the switch is reset or rebooted.
■The switch Fault LED and Link LED for the transceiver port are
blinking. The transceiver may not be installed correctly, or may be faulty.
Disconnect power from the networking device and reinstall the transceiver
into the module or networking device. Verify the transceiver screws are
tightened. Turn the device power back on, and if the flashing persists, the
transceiver may be faulty.
For additional troubleshooting, you can also use the device's console interface, the
switch’s web browser interface, or HP Top Tools for Hubs & Switches to trouble-
shoot and configure the High-Speed Transceiver port. See the switch's Management
and Configuration Guide for more information.
If you are still having trouble, see the “Customer Support Services” on page 7.

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 Transceiver.
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 port in your switch and your multimode fiber-
optic network cabling, and between the Gigabit-LX transmission 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
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 on page 5, there should not be a
need to use mode conditioning patch cords in your network. This is espe-
cially 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 transceiver.
59692336.fm Page 9 Monday, October 9, 2000 4:08 PM

Installing the Patch Cord
As shown in the illustration below, connect the patch cord to the Gigabit-
LX 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.
Make sure you purchase a patch cord that has SC connectors on the end
that connects to the Gigabit-LX Transceiver 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
