Using A Redundant Link - IBM 5075 Setting Up

Using a redundant link

A redundant link is a secondary HSL connection that your system can use if the
primary link experiences a failure. You can create a redundant link configuration
by connecting an extra HSL cable link between the expansion units and the system
unit.
To ensure continued access to your disk units in the event of a link failure, use a
redundant link configuration when you plan your cable layout.
Connecting your 5075 directly to an AS/400 system-unit
Figure 1 shows an example cable plan that uses a redundant link configuration.
