HP ProCurve Gigabit Transceivers
Installation Guide
Introduction
The HP ProCurve Gigabit Transceivers are used to provide 1000 Mbps
connections to other compatible network devices for the HP ProCurve
Switch 2424M Gigabit Stacking Module and other HP networking devices
that are designed to accept these transceivers. The transceivers are installed
into the transceiver slots of the HP networking device or device module.
This document describes how to install, verify, and troubleshoot the
following two HP ProCurve Gigabit Transceivers:
The Gigabit-SX transceiver complies with the 1000Base-SX standard and is
used with multimode fiber-optic cable. The Gigabit-LX transceiver complies
with the 1000Base-LX standard and is used with either single-mode or
multimode fiber-optic cable. For more information on the cables used with
these transceivers and the supported cable lengths, see page 4.
Note:
The illustrations in this document show the above listed units being used
with the HP J4130A ProCurve Switch 2424M Gigabit Stacking Module. The
procedures described in this document also pertain to using these units in
other Gigabit HP networking devices that are designed to accept them.

Installation Steps
Caution
To avoid possible damage to the transceiver circuitry, turn off power to the
device before installing the transceiver into it. If you are installing the
transceivers in 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.
To install the HP Gigabit Transceivers, follow these steps:
1. Insert the transceiver into an HP networking device’s Gigabit
transceiver slot and secure the retaining screws.
2. If the Gigabit 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, apply power to the 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. Unplug the HP networking device from the AC power source, or
remove the module with the transceiver slots from the networking
device. Then, 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 HP networking device or device module.
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 Gigabit 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 a transceiver sliding into an HP ProCurve Gigabit Stacking
Module.
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. Reinstall the module into the networking device and make sure the
device is powered on, or if the transceiver is installed directly into a
networking device, power the device on.

slot until it snaps into place

Connect Network Cables to the Transceiver Port
The following network cables should be used with the Gigabit-SX and
Gigabit-LX transceivers.
To connect a fiber-optic cable to a
transceiver:
1. 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.

with the ITU-T G.652 and

4. When power is applied to this trans-
ceiver 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”,
below.
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 cable fibers 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. 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: Gigabit-SX or Gigabit-LX.
• 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 Fault LED and Link LED for the transceiver port are
flashing. Turn off the power and reinstall the transceiver into the module
or networking device and 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 Gigabit 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.
