MultiVOIP Gatekeeper User Guide
Introduction
This section provides a variety of approaches should the Gatekeeper fail to operate properly. Your
Gatekeeper was tested thoroughly at the factory before it was shipped. If you are unable to make a
successful connection, it is possible that the Gatekeeper is defective. However, it is more likely that the
source of your problem lies elsewhere. As with any microcomputer product, start with simple hardware
and software problems and work toward more complex problems (e.g., operating system and/or
applications).
Hardware Troubleshooting
The following material addresses some of the typical problems and provides some basic solutions. If a
problem arises while you are in an application, see the software documentation.
• No Video
— Verify that power is ON (LED in power switch is lit).
— Verify that the SBC and NIC adapter board are connected properly.
Note: Make sure to turn power OFF to reconnect boards.
— Verify that monitor is turned ON, power is connected to monitor, and video cable is
connected to video connector on SBC.
— Verify that the two (or four) 72-pin memory SIMMs are connected properly on the SBC.
The SIMMs must be the same brand, type, size, and speed.
— Disconnect all cables (except the video cable) from the SBC and NIC board, then power
ON the Gatekeeper . If the Gatekeeper now has video, then there is a problem with one
of the cables or one of the peripherals. Try each cable, one at a time, to isolate the bad
cable or peripheral.
— Verify that blower fans are running. If power is on and a fan is stopped, check to be sure
power connectors from power supply to midplane are fully connected and in their proper
orientation, as shown on Figure TBD.
— If problem persists, contact MultiTech's Technical Support department (see Chapter
TBD).
• SBC does not boot correctly or hangs after video appears
— Run BIOS Setup Utility to verify correct configuration for system and drives (i.e., press
DEL key as system boots to enter BIOS Setup).
— If boot PROM is used, verify that network and NIC board are configured properly to see
the network.
— Verify that SBC and NIC board are seated properly in backplane.
Note: Make sure to turn power off to reconnect boards.
— Drive cables are not connected properly or parameters are not set properly in setup.
— If a non-bootable diskette is in the floppy drive, remove it and try booting
again.
— Verify that enough memory is installed to load the intended applications.
— Verify that two (or four) 72-pin SIMMs are seated properly on the SBC. The SIMMs must
be the same brand, type, size and speed.
— Remove NIC board. If system boots then, there was a conflict with the NIC board.
