♦ Auto-partition (blinking amber)
The indicator of a port blinks amber when the port is automatically par-
titioned due to an abnormal network condition.
The hub will temporarily partition a port when too many line errors or
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.
♦ Disabled (steady amber)
The indicator of a port is amber when the port has been manually dis-
abled. No packet transmission or reception can occur on the port. Ports
can be manually disabled and enabled from the management station if a
stack is being managed via a DFE-2616i/DFE-2616ix or DFE-
2624i/DFE-2624ix master hub.
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.
