♦ Rx (for BNC port). ◊ Blinking: Packet reception is occurring. ◊ OFF: No packet reception. ♦ Partition (for each UTP port). ◊ ON: The UTP port is being partitioned off due to excessive packet collisions. Note that the UTP cable between a hub port and a non-repeater node must contain straight-through wires (no cross-over). ◊ OFF: Segment has no problem. ♦ Partition (for BNC port). ◊ ON: The BNC port is being partitioned off due to (1) no cable is connected, (2) faulty cable or connectors, (3) excessive packet collisions, (4) a disconnected point somewhere along the entire thin coaxial cable length, or (5) unterminated segment. Check all connectors along the cable length. If segment is not terminated, terminate both ends with 50-ohm terminators. ◊ OFF: (1) Cable is connected and (2) segment has no problem. ♦ Uplink ◊ ON: The "9" UTP port is in the Uplink position (crosswired). ◊ OFF: The "9" UTP port is in the Normal position (straight-through wires). 16 Installation

Installation
♦
Rx
(
for BNC port
).
◊
Blinking:
Packet reception is occurring.
◊
OFF:
No packet reception.
♦
Partition
(
for each UTP port
).
◊
ON:
The UTP port is being partitioned off due to excessive
packet collisions.
Note that the UTP cable between a hub
port and a non-repeater node must contain straight-through
wires (no cross-over).
◊
OFF:
Segment has no problem.
♦
Partition
(
for BNC port
).
◊
ON:
The BNC port is being partitioned off due to (1) no
cable is connected, (2) faulty cable or connectors, (3)
excessive packet collisions, (4) a disconnected point
somewhere along the entire thin coaxial cable length, or (5)
unterminated segment.
Check all connectors along the
cable length.
If segment is not terminated, terminate both
ends with 50-ohm terminators.
◊
OFF:
(1) Cable is connected and (2) segment has no
problem.
♦
Uplink
◊
ON:
The “9” UTP port is in the
Uplink
position (cross-
wired).
◊
OFF:
The “9” UTP port is in the
Normal
position
(straight-through wires).
