ATTENTION

Many network management software packages assume a cascade down (stack down) configuration, Nortel recommends the usage of this configuration.

Cascade down stack configuration

In a cascade up (stack up) configuration, the base unit is physically located as the top unit in the stack. The cable connected to the Cascade Down connector of the base unit terminates in the Cascade Up connector physically located at the bottom of the stack. This next unit is designated Unit

2.The stack is wired upward through the units and the system continues to number in this manner throughout the stack. In this configuration, the base unit discovers the stack in a cascade up (stack up) direction. The following illustration demonstrates a cascade up (stack up) configuration.
