Introducing the CPU Status Page

The BMEH584040(S) and BMEH586040(S) Hot Standby CPUs include a Rack Viewer web page. Use this page to view CPU information, including:

  • LEDs status

  • processor identification

  • application signature identification

  • select application configuration settings

Access this page from the Diagnostics tab (System > Rack Viewer).

This example of a Rack Viewer page shows a Hot Standby CPU on its rack with a power supply:

Accessing the Rack Viewer Page

Access the Rack Viewer page from the Diagnostics menu. In the navigation menu at the left side of the page, select Menu > System > Rack Viewer:

Rack Viewer page (HSBY CPU):

This example of a Rack Viewer page shows the Hot Standby connection between a primary CPU rack and a standby CPU rack. The Hot Standby connection (dashed line) is green when the Hot Standby link is healthy. If the Hot Standby link is not healthy, the dashed line is red.
