Workstation Problems 
Most non-cabling problems result from improper configuration of the network 
interface card (NIC) and its corresponding driver. The following points will be 
helpful: 
• 
Like other add-on cards in the workstation or server, NIC must have unique 
memory address, I/O address, and interrupt. The settings on a particular card 
must not conflict with the settings on any other card in the same station. 
Please refer the User's manual of the NIC, computers, and Networking 
operating systems to determine the proper configuration 
• 
The selection of half or full duplex, the speed of 10 or 100Mbps for the NIC 
setting must match the mode and speed setting of the corresponding port of 
the Hub. For NWay Auto-Negotiation setting, both link partners will auto-adjust 
to the highest allowable speed and mode operation
 
Other Problems 
Other specific problems may be diagnosed by using the LEDs, as below. 
Power LED is off when the AC Power switch is ON: 
•  Defective power supply unit or fuse 
•  Incorrect AC voltage 
•  Defective Hub 
Link/Act LED is off at any Fiber: 
•  Faulty node or wiring connection  
For fiber -  the "TX", "RX" cables should be paired at both ends 
 No Link signal is received from the remote node/site 
100Base-X Port at irregular traffic: 
•  Abnormal or invalid transmission status(mode / speed) between local and 
remote link partners, i.e., full-duplex port is connecting to a half-duplex port, 
or 10Mbps port is connecting to a 100Mbps device 
Hub Diagnostic Test 
  The switch hub performs self-diagnostic test at major hub modules upon 
power on, LED indicators will go to normal status if no problem occurred 
  To reset or restart the hub, power off the hub and wait for 10 seconds, then 
power on it again
