External Indicators
Three LEDs show from the front of the disk carrier. The green LED is the power
light, the red LED is the activity light, and the yellow is the fail indicator. The
activity signal is also displayed on the module’s LED panel using the small cir-
cular red LED.
External SCSI Devices
External SCSI devices may be connected in two ways:
Front Panel Connections:
Some processor board types have SCSI bus connections on their front panels.
When using these the cable should be routed behind the module’s front panel
and into the cable guide below the module.
Module SCSI Card Connections:
The module SCSI cards (MK516) fitted to the rear of the module has an exter-
nal Beta Phase connection. This may be used to connect the processor boards
to a Peripheral Module.
