Step 1: Install z/OS Communications Server

Before you begin the installation:

Install z/OS Communications Server with other elements of z/OS. If you use the ServerPac method of installation, see z/OS Installing Your Order; if you use the CBPDO method of installation, see z/OS V2R1 Program Directory. When appropriate, that information will direct you back to this information to customize the TCP/IP data sets and procedures and verify their configuration.
