USER GUIDE
The SuperStack
®II Dual Speed Hub – PS Hub Cascade Converter Kit is used for
connecting the SuperStack II Dual Speed Hub 500 to a SuperStack II PS Hub.
PS Hubs have four separate 10Mbps segments (segments 1–4) which are extended
through a stack of PS Hubs by the PS Hub’s cascade cables, as shown below.
The Cascade Converter Kit allows you to connect segment 1 of the PS Hub stack
directly to the Dual Speed Hub 500 stack’s 10Mbps segment (and the 100Mbps
segment, through the internal switch). This allows the workstations that are
connected to that PS Hub segment to communicate with the 10Mbps and 100Mbps
workstations and equipment that are connected to the Dual Speed Hub 500 stack.
The maximum number of PS Hub units and Dual Speed Hub 500 units that you can
connect using the Cascade Converter is eight. You can have a maximum of
6m (19.6ft) of cascade cabling (including the cable that connects the PS Hub stack
and Dual Speed Hub 500 stack) between the top and bottom units.
The Cascade Converter Kit is made up of a Cascade Cable and a Cascade Converter.
Connect the Cascade Cable to the ‘Dual Speed Hub Cable’ end of the Cascade
Converter (indicated on top of the Cascade Converter), as shown below.

Using the Cascade Converter Kit
The Cascade Converter Kit links the bottom unit in your PS Hub stack to the top
unit in your Dual Speed Hub 500 stack, so the PS Hub stack should be above the
Dual Speed Hub 500 stack.
For safety information, refer to the information in the user guides that accompany
the Dual Speed Hub 500 and the PS Hub.
1Connecting to the PS Hub
To connect to the PS Hub, connect the Cascade Converter to the DOWN port of the
bottom unit in the PS Hub stack, as shown below.
2Connecting to the Dual Speed Hub 500
To connect to the Dual Speed Hub 500, connect the Cascade Cable (that is
connected to the Cascade Converter) directly to the UP port of the top unit in the
Dual Speed Hub 500 stack, as shown below.
If you are using Hot Swap Cascade Units with your Dual Speed Hub 500 stack or
PS Hub stack, you can connect the Cascade Converter Kit directly to these Hot Swap
Cascade Units.
