5. If you want all Gigabit Ethernet ports to detect and then use the operating mode and
speed of the network segment to which those ports are connected, select the
Auto
Negotiate Port Speed and Mode check box. Otherwise, clear the check box to disable auto
negotiation on all Gigabit Ethernet ports.
All Gigabit Ethernet ports use auto negotiation. If auto negotiation is not set on a
Gigabit Ethernet port, that port uses the full-duplex mode and operates at 1000 Mbps.
6. If you want to configure 10/100 Mbps Ethernet ports, do one of the following.
Otherwise, skip to
step 7 .
– If you want all 10/100 Mbps Ethernet ports to detect and then use the operating
mode or speed of the network segment to which the port is connected, select the
appropriate
Autodetect options.
– If you want to set all 10/100 Mbps Ethernet ports’ operating mode or speed to a
specific setting, select the appropriate buttons.
All 10/100 Mbps Ethernet ports use autodetection by default.
The 100 FX ports do not use auto-detection. They always use full-duplex mode and
operate at 100 Mbps.
Note:
If you select an operating mode or speed, the setting disables autodetection
for that parameter on the port. For example, if you set the speed of a segment
to 10 Mbps, that segment no longer uses autodetection for the port speed and
will always attempt to operate at 10 Mbps.
