This chapter describes common problems that may occur with this product and what to do about them.
If any problems occur that are not described here, check to confirm that the re-occur, then contact the
store where you purchased the product.
When Communication Fails
Check hardware
- Check that the LAN cables are connected correctly.
- Check that the serial cables are connected correctly.
Check software
- Was the unit started with the ID switch set to “F”?
- Is the ID switch set correctly (0 - E)?
- Is the MODE switch set correctly?
- Is the baud rate set correctly?
- Is the operating mode set correctly?
- Are the IP address and subnet mask set correctly?
When SNMP Connections Fail
- It is possible that the device cannot locate a control parameter, or that a private MIB has not been
compiled. See Chapter 6.
- If MIB settings have not been made, the correct community name may not have been entered. Be
sure the community name setting agrees with the network manager's setting.
- Check the SNMP settings that are being used.
When the RP-COM(FIT)H, RP-COM(FIT)H-AF Will Not Start
Check the power LED
- Be sure the power LED is on. If not, check that the AC adapter, power supply connector, and
mains power plug are connected correctly.
- If the POWER LED does not illuminate within 3 minutes of turning on the power or resetting via
the utility software, first check whether the device ID is set to “F”.
- If the device ID is set to “F”, change to a value other than “F”, then restart.
- If the device ID is not set to “F”, it is possible that the firmware is faulty.
In this case, use the utility software to update the firmware.
