Cascade A Out Connector
Provides an attachment point for connecting this unit to another unit via the
cascade cable. A return cable from another unit's Cascade A Out connector to this
unit's Cascade A In connector completes the stack connection (see the example
shown in Figure 1-18).
Unit Select Switch
The Unit Select switch (up = Base) determines the base unit for the stack
configuration (see "Base Unit" on page 1-43). The Unit Select switch status is
displayed on the BayStack 450 LED display panel. When the Unit Select switch is
in the Base (up) position, all other Unit Select switches in the stack configuration
must be set to Off (down).
