Last Updated: July 8, 1998 (important changes are identified by * * a ! in margin * * Assumptions used by CF3745 when configuring CLPs (line weights..)* * are summarized after the following Licensed Internal Code section* * (for details, use help key). * * * * LICENSED INTERNAL CODE requirements (3746-900, 3746-950) * * * * The following describes the functional levels of microcode (ECA),* * starting with the latest announced ones (possibly not available).* * For each level, only the new supported functions are * * indicated, as they are cumulative with the functions of all * * the other levels down in the list (older levels). Once a new * ! level is available, all the new machines (and selected MES which * * ship with microcode) are automatically shipped at this level of * * microcode. The new level is not distributed to the installed * * 3746-900s and 3746-950s, except some levels like the Engineering * * Change (EC) level D22510K (ECA number 142) of 12/95. * * * ! If a customer wants to benefit from functional enhancements, such* ! as CCM improvements, which are not orderable via any optional * ! licensed internal code feature, and the minimum EC level for the * * requested function is not installed, or planned to be installed, * * for example as part of an MES(*), order the most current ECA * * number via the IBM Service representative * * * * The EC number indicated for a given ECA number reflects the * * technical level of the mcode at the availability date of the ECA.* * The alphabetic index (A, B,...) complementing the EC number is * * incremented when a new technical level starts shipping. * * Starting with ECA 167,the operator can display the active ECA and* * EC numbers of the 3746-9x0(s) connected to the Service Processor * * (*) When an MES is shipped with mcode (see description below), * * this mcode is shipped at the most current FUNCTIONAL level * * (ECA number) and TECHNICAL level (EC number) * * * !16.
