9. Network check items (Ethernet Port)
Check items Countermeasure
1. Is the twisted pair cable connected
between the Ethernet Port and HUB?
1. Verify the twisted pair cable connections between the
Ethernet Port and HUB.
2. How long (in meters) are the twisted pair
cable (i.e. segment lengths)?
2. The maximum segment length for 10BASE-T cabling is
100 meters.
Network cable
check
1. Do all ports on the network respond to ping
correctly?
1. Inspect the twisted pair cables for missing termination
resistors and damage.
2. Is the collision frequently happen?
Can you confirm the table indicating the
collision?
2. Since network loading is heavy:
• Transmission efficiency can be degraded (TCP), and
• There is an increased possibility of packet loss (UDP).
Therefore, the circuit usage conditions should be reviewed.
3. Are the error counters read out from the
RAS information increasing as time
passes?
Error counters: Alignment error, Short
packet, CRC error
3. Check whether there are any defective (or substandard)
connections on the cables and HUB.
Check for the presence of noise sources in the vicinity of
the network cables.
