Description of Hardware
Gigabit Uplink Module
The EM4601-SX-SC fiber optic module is designed for use in Accton switch models
which have a single-port Gigabit Ethernet transceiver slot. At present, suitable units
include the CheetahSwitch Workgroup-3628 (ES3628). Detailed information about
configuring these modules and advice about Fast Ethernet configuration rules can
be found in the switch’s user guide.
Warning: Before installing or removing the EM4601-SX-SC module, first disconnect the
switch from the main power supply. For full safety instructions, please refer to
the user guide that accompanies the switch.
Accton’s EM4601-SX-SC fiber optic module provides a Gigabit port which can be
used for a high-speed backbone or server connection. It contains one 1000BASE-SX
port that can be connected to a site up to 550 m (1805 ft) away with fiber cable.
Gigabit Port LEDs
Port status LEDs are also provided on the front of the module for “at-a-glance”
network monitoring. The following table details the indicator functions provided by
the module:
Extender Module LEDs
LEDs Condition Status
Link On A valid link has been established on the port.
Flashing
Port has been manually disabled, or partitioned by the
system due to excessive errors.
TX On Port is transmitting packets.
RX On Port is receiving packets.

Installing the Module
Caution: Do not install this module in any unit other than the CheetahSwitch
Workgroup-3628 (ES3628). Contact your distributor for advice on newly released
switches which may be designed for use with these modules.
The EM4601-SX-SC fiber optic module is field installable. Just follow the
instructions below.
Package Contents
This package includes:
• One EM4601-SX-SC fiber optic module
• This User Guide
• Owner registration card
Handling the Modules
Caution: The EM4601-SX-SC module 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
from the switch.
2. Remove network cables: If you are replacing a module, remove the cable
attached to any 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.

Description of Hardware
3
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.
5. Insert the new module into the switch: Holding the new module with the text
on the front panel upright, carefully slide the module into the lower right slot on
the rear panel, and press gently until it snaps into place. Be sure the new
module’s front panel is flush with the switch panel.
Note: Media expansion modules can only be placed in the lower slot.

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 to the module: Connect fiber cable to the port on
the newly installed module. See “Maximum Cable Length” on page 5 in this
guide for further information.
8. Power on the switch: Reconnect the previously removed power sources to the
switch. Check the LED indicators for the fiber ports on the module’s bracket to
ensure that they are operating correctly. Refer to “Gigabit Port LEDs” on page 1
for a description of the LED indications. If the module does not respond, see
“Troubleshooting” on page 5.

Troubleshooting
If you experience any problems with the module, check the following items before
contacting Accton Technical Support:
• Ensure the switch with the fiber optic 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 module port is configured to match the communication mode used
by the attached device (full or half 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 the Cheetah ST Converter (Part Number: ST5002) to attach 62.5/
125 micron fiber cable with an ST-type connector to the SC-type port on the fiber
optic module.
