## 7.1 Preparing console definition 

A non-SNA console is a console that is required for IPL, z/OS system operation, and management. You must define at least one non-SNA console to your z/OS system. To define the non-SNA console, use the OSA-Express Integrated Console Controller (OSA-ICC) function. For more information, see z Systems Open Systems Adapter Integrated Console Controller User’s Guide , SC27-9003. 

The process includes the following steps: 

1. Define the OSC CHPID and the CNTLUNIT. 

2. Define the 3270-X IODEVICE. 

3. Configure OSA-ICC by using the OSA Advanced facilities. 

4. Export or import OSA-ICC configuration (optional). 

5. Activate OSA-ICC configuration by using the OSA Advanced facilities. 

6. Setup Personal Communications. 

Note:  The OSC channel can be defined only for OSA-Express5s/6s 1000Base-T cards. 

You must configure OSA-ICC when you upgrade to z14 ZR1 from an z13s server or when a new z14 ZR1 is installed. 

For an upgrade from z13s, the OSA-ICC configuration is automatically upgraded to z14 ZR1. 

## 7.2 Defining the OSA-ICC 

Before you configure OSA-ICC, you must define the OSC CHPID, CNTLUNIT, and 3270-X IODEVICE to the I/O configuration. 

For more information about defining OSC channel by using HCD, see Chapter 13, “Adding network devices” on page 293, and Chapter 11, “Adding LPARs and OSCONFIGs” on page 269.
