This chapter contains information to help you solve issues. If the Managed Switch is not functioning
properly, make sure the Managed Switch was set up according to instructions in this manual.
■ The Link LED is not lit.
Solution:
Check the cable connection and remove duplex mode of the Managed Switch.
■ Some stations cannot talk to other stations located on the other port.
