24-Port 10/100 Ethernet Switch Installation6
Data path loops. Check for data path loops. There should be only one cabling path at any time between
the switch and the device to which it connects.
Transmission mode
The RJ-45 ports use auto-negotiation to set the transmission mode to either full-duplex or half-duplex.
Verify that each port is set to the same transmission mode used by the attached device. If the attached
device operates at half-duplex, the default when auto-negotiation fails, it does not support
auto-negotiation.
