Front Panel LEDs

The LEDs on the front panel of the VTrak J830s or J630s unit provide important

status information about the subsystem.

When boot-up is finished and the VTrak subsystem is functioning normally:

• Power and Global enclosure status LEDs display green continuously.

• I/O module activity LEDs flash green when there is activity on the SAS ports.

• System heartbeat LED blinks green once every 4 seconds if one I/O module

is installed or once every 2 seconds if two I/O modules are installed.
