NSTALLING THE MODULE

Handling the Modules

CAUTION: The modules can easily be damaged by electrostatic

discharge.

To prevent electrostatic damage, observe the following guidelines:

• Do not remove the module from its packaging until you are
ready to install it.

Do not touch any of the module’s pins, connectors or components

•

• Hold the module only by its edges or front panel.

• Wear an anti-static wristband connected to a suitable earth
ground whenever handling the module.

• Store or transport this module only in appropriate anti-static
packaging.

Instructions

CAUTION: The switch must be powered off before installing or

replacing any module.

1. Power off the switch: Disconnect the AC power cord from

the switch. If a redundant power unit (RPU) is present,
disconnect its DC cable connection to the switch.

2. Remove network cables: If you are replacing a module,

remove the cable attached to the port on the module.

3. Loosen the screws on the installed module or slot

faceplate: Using your fingers or a flathead screwdriver, turn

the screws securing the module (or faceplate on the slot) in a
counter-clockwise direction until they are free of the chassis.
Be sure not to completely remove the screws from the module
or faceplate.

4. Remove the installed module or faceplate: Firmly pull on

the screws until the module is free of the switch. Carefully
slide the module straight out of the slot.

Keep the original faceplate for future use. If you should
remove the module, replace the faceplate to prevent dust and
debris from entering the unit and to maintain proper air flow.

6. Secure the new module: Secure the new module in place by

screwing the attached screws clockwise into the switch’s
chassis. Tighten them enough to secure the module, but not so
tight as to prevent them from being unscrewed by hand.

7. Connect the network cable: Connect RJ-45 or fiber cable to

the port on the newly installed module. See “Cable Specifications”
on page 9 in this guide for further information.

8. Power on the switch: Reconnect the previously removed

power sources to the switch. Check the switch’s front-panel
LED indicators to ensure that the module is operating correctly.
Refer to the table of LEDs on page 2 for a description of the LED
indications. If the module does not respond, see
“Troubleshooting” on page 7.

ROUBLESHOOTING

If you experience any problems with the module, check the
following items before contacting SMC Technical Support:

• Ensure that the switch with the Extender Module is powered up.

• Ensure that the device attached to the module is powered up

and operating correctly.

• Ensure that the module is properly seated in the slot.

• Verify that the attached device is configured to match the

communication mode used by the module (100/1000 Mbps and
full duplex).

• Check the connectors on both ends of the cable to be sure they
are properly engaged. When attaching fiber cable to an SC-type
port, be sure the plug clicks into place to ensure that it is
properly seated.

• If you are using fiber optic cable with an ST-type connector (in
conjunction with the SC-ST Converter*), try switching the TX
and RX connectors.

• Be sure the fiber terminators are clean. You can clean the cable
plugs by wiping them gently with a clean tissue or cotton ball
moistened with a little ethanol. Dirty fiber terminators on fiber
optic cables will impair the quality of the light transmitted
through the cable.

*

You may use an SC-ST Converter (SMC Part Number:
99-012034-091) to attach fiber cable with an ST-type
connector to the SC-type port on the 100 Mbps Extender
Module.

Caution: DO NOT plug a phone jack connector into any RJ-45

port. Use only twisted-pair cables with RJ-45
connectors that conform with FCC standards.

The RJ-45 port on the SMC6725L2GT module supports 1000, 100,
and 10 Mbps Ethernet operation, with auto-negotiation of flow
control.

Caution: Each wire pair must be attached to the RJ-45

connectors in a specific orientation.

The figure below illustrates how the pins on the RJ-45 connector
are numbered. Be sure to hold the connectors in the same
orientation when attaching the wires to the pins.

1000BASE-T Pin Assignments

1000BASE-T ports support automatic MDI/MDI-X operation, so
you can use straight-through cables for all network connections to
PCs or servers, or to other switches or hubs. In straight-through
cable, pins 1-8, at one end of the cable, are connected straight
through to pins 1-8 at the other end of the cable.

Use 100-ohm Category 5 or 5e unshielded twisted-pair (UTP) or
shielded twisted-pair (STP) cable for 1000BASE-T connections.
Also be sure
exceed 100 meters (328 feet)

The table below shows the 1000BASE-T MDI and MDI-X port
pinouts. These ports require that all four pairs of wires be
connected. Note that for 1000BASE-T operation, all four pairs of
wires are used for both transmit and receive.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX
connections should also work for 1000BASE-T, providing that all
four wire pairs are connected. However, it is recommended that
for all critical connections, or any new cable installations, Category
5e (enhanced Category 5) cable should be used. The Category 5e
specification includes test parameters that are only
recommendations for Category 5. Therefore, the first step in
preparing existing Category 5 cabling for running 1000BASE-T is a
simple test of the cable installation to be sure that it complies with
the IEEE 802.3ab standards.

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation,
Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This
cable testing information is specified in the ANSI/TIA/EIA-TSB-67
standard. Additionally, cables must also pass test parameters for
Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These
tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The
Additional Transmission Performance Guidelines for 100 Ohm
4-Pair Category 5 Cabling.”

Note that when testing your cable installation, be sure to include
all patch cables between switches and end devices.

Adjusting Existing Category 5 Cabling

If your existing Category 5 installation does not meet one of the
test parameters for 1000BASE-T, there are basically three measures
that can be applied to try to correct the problem:

1. Replace any Category 5 patch cables with high-performance

Category 5e cables.

2. Reduce the number of connectors used in the link.

3. Reconnect some of the connectors in the link.
