receptacle on the rear panel of the Ethernet Hub.
Plug the other end of the power cord into an
electric service outlet. Turn on power to the
Ethernet Hub by switching its rear-panel power
switch to the on position.
LED Indicators
LED indicators are located on the front panel of
the Ethernet Hub.
Jabber LED
One Jabber LED for all ports. This LED flashes
red when the Ethernet Hub detects a data packet
that is defective (exceeds allowable length). This
kind of error will ordinarily be managed by the
offending Ethernet adapter itself, in which case
the Jabber LED will return to its normal off
(dark) state.
Collision LED
One Collision LED for all ports. A collision
occurs when two stations within a collision
domain attempt to transmit at the same time.
Intermittent flashing yellow of the Collision LED
is normal; the contending adapters resolve each
collision by means of a wait-then-retransmit
algorithm. Fre-quency of collisions is an
indicator of heavy traffic on the network.
Link/Rx LEDs
One Link/Rx LED for each numbered port.
Steady green (Link state) indicates that the port
has good linkage to its partner device. Flashing
