[KV1701A/E (8 x 32) Switches Shown]
Although a blocking configuration limits user access, it can provide access to additional
target devices in the switching system. In a blocking configuration, all of the available
user paths from the primary switch are not connected, which might leave some server
ports unconnected. These server ports can be used to attach additional target devices or
cascaded switches.
When setting up your switching system, you may combine blocking and non-blocking
configurations. Choose the best configuration or combination of configurations for your
switching system. If you choose a blocking configuration, manage user access by planning
which target devices are connected to each switch. For example, you might choose to split
up target devices that require frequent access among each cascaded switch so the
maximum number of user paths are available to connect to that target device.
To install a cascaded Octet switching system:
1. Position the Octet switches to be attached and select a switch to be the
primary switch.
