GLYPH<SM590000> Integrated 3270 console security and performance enhancements GLYPH<SM590000> Starting with HMC Version 2.15.0, zBX is no longer supported.  GLYPH<SM590000> With HMC/SE Driver 41, the Sysplex Time task was removed from the SE; as such, an  HMC version 2.15.0 is required to manage STP on a z15 CPC. GLYPH<SM590000> HMC 2.15.0 supports managing N-2 generation CPCs only (z15, z14 ZR1, z14, z13s,  and z13). GLYPH<SM590000> The DVD drives for the z15 hardware are no longer available on the new build HMC or  the SE. Feature code (FC) 0063 provides rack-mounted HMC, and FC 0062 provides the tower  version of the stand-alone HMC. The HMC FC0063 (2461-SE3) is a 1U server that can be ordered with an optional IBM 1U  rack-mounted tray that features a monitor and a keyboard/pointing device (KMM FC 0154).  The HMC system unit and the KMM tray must be rack-mounted in two adjacent 1U locations  in the “ergonomic zone” between 21U and 26U in a standard 19-inch rack.  The rack-mounted HMC can be installed in a customer-provided rack (it cannot be mounted in  the z15 CPC frames). Three C13 power receptacles are required: two for the system unit and  one for the display and keyboard, as shown in Figure 10-5. On HMC 2.15.0, the internal framework was reworked; therefore, performance for  integrated 3270 console is improved. Also, RACF security checking is required based on  user logon.
