Installation Notes

Please read these notes before proceeding.

The HP Procurve High-Speed Transceivers are supported in the following HP Procurve networking devices:

• Series 2300 and 2500 Switches

• Series 4100GL Switches

For these switches, it is not necessary to turn off power to the device before installing the transceiver into it:

• For the Series 2300 and 2500 switches, you can install the transceivers while the switches are powered on, but you must reset or reboot the switch after installing the transceiver to initialize and activate it.

• For the Series 4100GL switches, the transceivers are installed in the Gigabit Transceiver GL Module. In these switches, the transceivers are fully “hot swappable”—you can install or remove them at any time without having to remove power from the device or without having to first remove the module from the switch, and without having to reset the switch. If you wish, you can install the transceiver into the module first before installing the module into the switch.

Please see the installation guide for the switch or module for more information on installing the transceivers.

Note: As of the printing of this manual, the HP Procurve Switch 2424M

(J4093A) and its transceiver module, the HP Procurve Switch 2424M Gigabit Stacking Module (J4130A) are obsolete. As a result, the Gigabit-SX Transceiver, J4131B, has not been tested in these devices and is therefore not supported. The other transceivers described in this manual were previously tested and are supported in the Switch 2424M and its Gigabit Stacking Module.

For information on using transceivers in the HP Procurve Switch 2424M and the Gigabit Stacking Module, see their manuals on the HP Procurve web site, http://www.hp.com/go/hpprocurve.

Installation Steps

To install the HP Procurve High-Speed Transceivers, follow these steps:

1. Fully insert the transceiver into an HP networking device's transceiver slot until the transceiver “snaps” into place, and secure the transceiver with the retaining screws.

If the transceiver slot is in a module that has not yet been installed into the switch, then install the module into the switch.

2. For the Series 2300 and 2500 Switches, reset or reboot the switch.

3. 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. 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. Retain the cover plate for possible future use.

loosen these screws and remove the cover plate

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 transceiver by its bulkhead or edges, taking care not touch any of its board components or metal connectors.

xcvrs_3-2002.fm Page 4 Tuesday, April 2, 2002 3:23 PM

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 switch or module. The following illustration shows the transceiver being installed in an HP Procurve Switch Gigabit Transceiver GL Module.

slide the transceiver i nto the slot until it snaps into place

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 module and you have not yet installed the module into the switch, 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.

Connect Network Cables to the Transceiver Port

The network cables identified in the table on the next page should be used with the HP Procurve High-Speed Transceivers.

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 page 11.

Note on 1000Base-T Cable Requirements. The Category 5 networking cables that work for 100Base-TX connections should also work for 1000Base-T, as long as all four-pairs are connected. But, for the most robust connections you should use cabling that complies with the Category 5E specifications, as described in Addendum 5 to the TIA-568-A standard (ANSI/TIA/EIA-568-A-5).

Because of the increased speed provided by 1000Base-T (Gigabit-T), network cable quality is more important than for either 10Base-T or 100Base-TX. Site cabling that is being used to carry 1000Base-T networking must comply with the IEEE 802.3ab standards. In particular, the cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). Additionally, unlike the cables for 100Base-TX, the 1000Base-T cables must pass tests for Equal-Level Far-End Crosstalk (ELFEXT), Multiple Disturber ELFEXT, and Return Loss.

When testing your cabling, be sure to include the patch cables that connect the switch and other end devices to the patch panels on your site. The patch cables are frequently overlooked when testing cable and they must also comply with the cabling standards.

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.

To connect a fiber-optic cable to a transceiver:

1. For fiber-optic transceivers, remove the plastic dust covers

notches

from the cable connectors and from the transceiver port.

2. Press the connector into the jack so that the tabs on the connector

Fiber cable with duplex SC 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.

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 singlemode 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 fiberoptic 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 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 transceiver.

xcvrs_3-2002.fm Page 10 Tuesday, April 2, 2002 3:23 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.

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 powered

on and operating correctly.

• 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 5 and that the cables comply with the specifications on that page.

• 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 information on page 2 to identify which transceivers are supported by which network devices.

• If the transceiver is installed in a Series 2300 or Series 2500 Switch, try

resetting or cycling power (turn the power off and then back on) on the switch. Resetting the switch causes a complete self test to be performed, which also tests the transceivers. If the transceiver is installed in a Series 4100GL switch, try removing and reinstalling the module in which the transceiver is installed. This will invoke the most complete self test of the transceiver, without needing to power cycle the switch.

• Verify that the transceiver port has not been disabled through a switch

configuration change. You can use the console interface, or, if you have configured an IP address on the switch, use the web browser interface, or HP TopTools for Hubs & Switches network management software to determine the state of the port and re-enable the port if necessary.

• Verify that the switch port configuration matches the configuration of

the attached device. For example, if the switch port is configured as

“Auto”, the port on the attached device also MUST be configured as “Auto”. Depending on the port type, twisted-pair or fiber-optic, if the

configurations don’t match, the results could be a very unreliable connection, or no link at all.



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 flashin g LED tells you that th e transceiver is not oper ational 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 troubleshoot 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” below.

Customer Support Services
