Diagnosing Hub Indicators
You can easily monitor the 1017A/B 10Base-T Hub using its comprehensive
panel indicators. These indicators help you identify problems the hub may
encounter. This section describes common problems and possible solutions.
Symptom:
CPU
indicator displays a steady green light long after power on.
Cause: Defective CPU
Solution: Have the hub’s CPU replaced. Ask for dealer assistance.
Symptom: Port Partition indicator lights (yellow LED).
Causes:
a.
Hub has partitioned 10Base-T (RJ-45), 10Base2 (BNC), or 10Base5
(AUI) port.
b.
Workstation’s network adapter, cable or hub port is defective.
c.
If BNC cabling is used, the BNC connector may not be terminated.
Solution:
a.
If port partitioning has occurred, the hub automatically enables the
port when the faulty condition disappears.
b.
The most common cause of disconnection from a network or port
partitioning is a defective network adapter or cable connection.
Check the corresponding cable connections, or the workstation’s
network adapter for possible defects. Replace the defective cable or
adapter.
c.
If a BNC cable connection is used, be sure the open ends of the BNC
segment are properly terminated with 50-ohm terminators.
NOTE
: The BNC Partition LED also lights if the BNC port is not used (that is, no BNC
cable connected). Ignore the BNC Partition LED if you did not connect a BNC cable.
