Installation Guide for the Model FS518 Fast Ethernet Switch

Network Adapter Cards

Make sure the network adapter cards installed in the PCs are in working condition and the software
driver has been installed.

Configuration

If problems occur after altering the network configuration, restore the original connections and
determine the problem by implementing the new changes, one procedure at a time. Make sure
that cable distances, repeater limits, and other physical aspects of the installation do not exceed
the Ethernet limitations.

Switch Integrity

If required, verify the integrity of the switch by resetting the switch. Turn power to the switch off
and then back on. If the problem continues and you have completed all the preceding diagnoses,
contact your NETGEAR point-of-sale representative.

Autonegotiation

The 10/100 Mbps ports will negotiate the correct duplex mode and speed, provided the link partner
supports autonegotiation. If the link partner does not support autonegotiation, only the speed will
be determined correctly and the duplex mode will default to half.
The Gigabit fiber ports will negotiate duplex mode and flow control, provided that the link partner
supports the autonegotiation mechanism. If not, a full-duplex, no flow controlled link will be
formed by default.
