Set link speed to 10 Base-T or 100 Base-T
When auto-negotiation is enabled, the manual link speed selection
is ignored. When auto-negotiation is disabled, the manual speed
selection is used to configure the link. Under certain circumstances
the auto-negotiation of link speed may fail. To avoid this, the SR470
defaults to manually configured 100 Base-T link speed. When setting
the link speed, a value of
j
equal to 0 selects 10 Base-T, and a value
of 1 selects 100 Base-T.
