ROUBLESHOOTING
This chapter provides troubleshooting information which can be used if the
AccessBuilder or one of its components fails to operate correctly. If after
reviewing the information in this chapter, you cannot correct the problem,
contact your AccessBuilder supplier for further assistance.
If the system fails to operate after you power it on, try the following
procedures, one at a time, until the problem is solved.
1 Power off the system. Unplug the power cable from the wall outlet and
plug it in again; then power on the system.
2 Test for power at the wall outlet by plugging in another device.
Select another outlet on a different circuit if necessary.
If the unit does not appear on the list of AccessBuilders found following the
autodiscovery process, check the front panel LEDs for activity. The Ethernet
or Token Ring cable connections should then be checked for proper
electrical connections.
When operating dual protocols (IP and IPX) over the network segment to
which the TABM workstation is attached, TABM can manage AccessBuilders
only for the protocol selected. Once the Transcend TABM application has
been installed for either an IP or IPX network type, it cannot be used to
manage the other, i.e., when installed for IP, TABM cannot manage IPX
AccessBuilders.
