Connectivity Testing
1. Connect each port to a node or workstation. Then connect the power cord.
2. Verify that the Link LEDs for Port 1 and Port 2 are lit.
If the Link LED does not light (TX):
❑
Verify that the switch’s port matches the speed selection of the device
attached to the other end.
❑
The switch settings are represented by each port’s LEDs. For
troubleshooting purposes, determine the current port settings, for
example auto-negotiation, 10 or 100 Mbps (speed) duplex mode.
❑
Change the MDI/MDI-X switch setting on the port and see if a link
occurs. If not, put the switch back to its original configuration.
If the Link LED does not light (FX):
❑
Make sure the remote end of the fiber optic cable is connected to a
100Base-FX device.
❑
Swap the near end fiber cable receive/transmit connectors.
Is the Link LED Lit?
The Link LEDs light when a proper connection between the corresponding 10/
100Base-TX or 100Base-FX port and the equipment connected to it is
established. If this LED is not lit, check for the problems listed as follows and
make corrections as necessary.
1. Problem 1:
The cable has been cut, damaged, or is the wrong type of cable.
❑
Solution 1:
— Try making the connection with a different cable. Be sure you are
using an undamaged cable of the correct type.
2. Problem 2:
Connected equipment is not turned ON or is not operating properly.
❑
Solution 2:
— Check the connected equipment (computer, another switch, etc.)
and turn ON the power.
— Make sure that the SPEED and Duplex Mode for each port of the
switch match the settings of the attached computer or additional
switch.
