10.2.7 User interface 10.2.8 Customize Product Engineering Access: Best practice Figure 10-9 Customize Product Engineering Access tab Figure 10-8 Dashboard status enhancement Starting with HMC Version 2.15.0, HMC Dashboard status was enhanced for accessibility. In z14, the status bar is in Home tab, and the HMC tasks are started in tabs. While working in  a task tab, the console status is not visible. As such, the user cannot be notified of hardware  or operating system messages, and other unacceptable status messages until the current  task is closed and user returns to the Home tab. In z15, the status bar was moved to the masthead of the HMC interface, which is always  visible (even when working in a task tab), as shown in Figure 10-8. At times, the HMC or the SE must be accessed in a support role to perform problem  determination tasks. The task to authorize IBM Product Engineering access to the console is shown in  Figure 10-9. When access is authorized, an IBM product engineer can use an exclusive user  ID and reserved password to log on to the console for problem determination actions. As shown in Figure 10-9, the task is available only to users with ACSADMIN authority.  Consider the following points: GLYPH<SM590000> Customers must ensure that redundant administrator users (ACSADMIN role) are  available for each console. GLYPH<SM590000> Customers must document contact information and procedures. GLYPH<SM590000> The “Welcome Text” task can be used to identify contact information so that IBM Service  personnel are informed about how to engage customer administrators if HMC or SE  access is needed. GLYPH<SM590000> The Product Engineering access options are disabled by default. 418  IBM z15 (8561) Technical Guide
