port of the switch. For NWay Auto-Negotiation setting, both link partners
will adjust to the highest allowable speed and mode operation.
Other Problems
Other specific problems may be diagnosed by using the LEDs as described below.
Power LED is OFF when CenturySwitch is connected to the AC source
• Defective fuse

• Defective switch
Link/Act LED is OFF at a port

located near a radio station, transmitter, etc.), try using shielded twisted-pair (STP)
cables instead of UTP cables.
Self-diagnostic test
• The CenturySwitch performs a self-diagnostic test at power on; LED
indicators go to their normal status if no problem occurred.
• To reset or restart the CenturySwitch, unplug it from the AC source and wait
10 seconds before applying power again.
CAUTION: Circuit devices are sensitive to static electricity which can damage
their delicate electronics. Dry weather conditions or walking across a carpeted
floor may cause you to acquire a static electric charge.
To protect your device, always:
• Touch the metal chassis of your computer to ground the static electrical
charge before you pick up the device.
• Pick up the device by holding it on the left and right edges only.
