Understanding Indicators14
♦ Receive (Rx) (blinking green)
When information is received on a port, its indicator will blink off
briefly. Upon reception, the data will be transmitted to all other con-
nected ports.
♦ Auto-partition (Auto-part) (steady amber)
The indicator of a port lights amber when the port is automatically par-
titioned due to an abnormal network condition.
The hub will temporarily partition a port when too many collisions are
detected on the port. While the segment is automatically partitioned,
the port will be isolated from the rest of the network segment. When
the problem is corrected or a valid data packet is received through the
port, the port is automatically reconnected.
Port Speed Indicators
There is also a port speed indicator for each of the twisted-pair ports on the
hub. A port’s speed indicator should light green when a 100BASE-TX de-
vice is connected to the port, and remain dark if the port is unconnected or
if a 10BASE-T device is connected.
Switch Indicator (DFE-908x Only)
The DFE-908x’s Switch indicator shines a steady green when the hub’s
built-in switch is functioning correctly. The indicator should shine when-
ever the hub has power.
