Appendix A. Troubleshooting

A.1 Status indicators

The green indicators built into the link connectors on each module provide useful feedback regarding the connection and power status:

During startup (of the local module)

One very short green flash: no valid DDC information available from a locally connected video monitor, no changes made to stored DDC information.

Single green flash: DDC information being read from a locally connected video monitor, but no changes made to stored DDC information.

Rapid green flash for 2 to 3 seconds, followed by single flash: New DDC information being read and stored from a locally con- nected video monitor.

Two green flashes - Checksum error prior to copying - no information will be programmed.

Three green flashes - Too much data to fit into the module - the module can hold a maximum of two pages of DDC informa- tion.

Rapid green flashing followed by four flashes - data was lost during copying - the default data was substituted. Repeat the power on process.

Rapid green flashing followed by five flashes - Checksum error during copying - the default data was substituted. Repeat the power on process.

During operation (either module)

Continual yellow: Valid CATx link to other module sensed.

Continual green: Correct power input sensed.

Important: The ServSwitch Wizard VGA-USB can be used with other hubs in the system, but please note that the local unit should not be connected to the downstream port of a bus-powered hub due to power constraints.
