Using the BayStack 410-24T 10BASE-T Switch

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 1-11).

Unit Select Switch

The Unit Select switch (up = Base) determines the base unit for the stack configuration (see “Initial Installation” on page 1-29). The Unit Select switch status is displayed on the BayStack 410-24T switch 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).

Cascade A In Connector

Provides an attachment point for accepting a cascade cable connection from an adjacent unit in the stack. A return cable from this unit’s Cascade A Out connector to the adjacent unit’s Cascade A In connector completes the stack connection (see the example shown in Figure 1-11).
