Installation and Operation 10-1
10. Troubleshooting
Basics
The front and rear panel LEDs can give diagnostic information for
troubleshooting. See section 6 for details.
Most connectivity problems are due to routing issues.
Check the routing tables on your networks to ensure that a valid path
exists between all nodes. See the installation and Operation sections for
details and example routings.
If possible, check connections by bypassing AROW
Fibre connectors
Do check that the correct grade of fibre is being used, especially on
longer connection runs. Optical connections are sensitive to both
overdrive and underdrive, so often incorrect signal levels can give rise to
obscure problems such as occasional packet loss or packet loss at high
data rates. If possible, use a fibre optic cable checker to determine signal
levels and quality.
Copper Connections
Please ensure that good quality screened CAT6 Ethernet cables suitable
for full-rate GBE connections are used.
System Integration
When mounting in a rack, or in proximity to other electrical equipment,
please ensure that normal system integration procedures are followed.
System integrators should ensure that the unit is not operated out of it’s
specification range, that cable and power connections are routed to
prevent interference, that correct start-up and shut-down procedures are
followed before system connections are altered and that all electrical and
safety procedures that apply in your territory or application area are
followed.
In particular, be aware that electro-static and electro-magnetic
disturbances may affect performance or damage the equipment and /or
data integrity and take steps to prevent these.
Consult a systems integration specialist if in doubt.
