Configuring the Hub 3-19 To use an STP module in a dual attachment configuration, for example, follow these steps: 1. If the attachment ports are not currently configured as B/A, configure the attachment ports to be B/A by invoking the set attach command. 2. Reset the hub. This step is unnecessary if the attachment ports are already set as B/A. 3. Install two cascade connectors. Insert one cascade connector in each of the two leftmost ports of the STP module in slot 1. 4. Attach the appropriate cables to the two cascade connectors. The cable from port number 1 (the B port) should attach to port A on the device to be dual attached. The cable from port number 2 (the A port) should attach to port B on the device.

Configuring the Hub
To use an STP module in a dual attachment configuration, for example, follow
these steps:
1.
If the attachment ports are not currently configured as B/A, configure
the attachment ports to be B/A by invoking the
set
attach
command.
2.
Reset the hub.
This step is unnecessary if the attachment ports are already set as B/A.
3.
Install two cascade connectors.
Insert one cascade connector in each of the two leftmost ports of the STP
module in slot 1.
4.
Attach the appropriate cables to the two cascade connectors.
The cable from port number 1 (the B port) should attach to port A on the
device to be dual attached.
The cable from port number 2 (the A port)
should attach to port B on the device.
