NETGEAR ProSafe GSM7212 Installation Manual page 21

Configuration
If problems occur after altering the network configuration, restore the original connections and determine
the problem by implementing the new changes, one step 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. To reset the switch, use the Tools>
Reset command or remove AC power from the switch and then reapply AC power. If the problem
continues, contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are outside
of North America, please refer to the support information card included with your product.
Auto Negotiation
The 10/100/1000 Mbps ports negotiate the correct duplex mode and speed if the device at the other end of
the link supports auto negotiation. If the device does not support auto negotiation, the switch only
determines the speed correctly and the duplex mode defaults to half-duplex.
The gigabit port on the Gigabit module negotiates speed, duplex mode, and flow control, provided that the
attached device supports auto-negotiation.
