The SuperStack

II Dual Speed Hub Hot Swap Cascade Unit is for use with the

SuperStack II Dual Speed Hub 500. In a stack of units, the Hot Swap Cascade Units

are used to connect the Dual Speed Hub Cascade Cables together. You can then

add and remove Dual Speed Hub 500 units from the stack by connecting or

disconnecting them from the Hot Swap Cascade Units. This means that if a unit fails

or is removed, it does not affect stack performance, because the remaining units in

the stack can continue to communicate.

The Hot Swap Cascade Unit is referred to as ‘

cascade unit

’ in this User Guide.

For safety information, refer to the information in the user guide that accompanies

the Dual Speed Hub 500.
