cases, the 10/100 speed or the F/H mode may be affected, but auto-cross in the
PXES4P Switches will still work. The auto-cross function cannot be disabled.
When an RJ-45 cable connection is made, and each time LINK is enabled,
auto-negotiation takes place (except for legacy products, which do not have auto-
negotiation and which go to the default state accordingly). The Switch advertises its
capability for 10 or 100 Mbps speed and F/H duplex mode, and the device at the other
end of the cable should similarly advertise / respond. Both sides will agree to the speed
and mode to be used per the IEEE 802.3u standard. Depending upon the devices
connected, this will result in agreement to operate at either 10 Mbps or 100Mbps speed,
and full- or half-duplex mode.
