5.5.2 Connectivity Problems
If the FE Switch Modules power up normally, but the workstations are
unable to communicate:
1. Check the LED for abnormalities which may help indicate the source
of the problem. (LED behavior during normal operation is explained
earlier in this chapter.)
2. Check the status of the ports using Local Console Manager
3. Check for loose connections between the switch module and devices.
4. Check that the proper type of cable is used: crossover or
straight-through, depending on the configuration; distance limitations
are adhered to, etc. (For more information on other limitations or
restrictions that may apply, see the IEEE 802.3 standards
specification.)
