What is the meaning of the two LEDs (one green and one yellow) on the side of the UltraBlock SCSI bridge?

The green and yellow LEDs on the side of the UltraBlock next to the HD68 SCSI connector indicate whether an LVD (Low Voltage Differential) or SE (Single-Ended) SCSI device is plugged into the UltraBlock. The green LED indicates LVD and the yellow LED indicates SE.
