Using the CR8e

Power Supply Error Conditions

During normal operation, anytime one of the required number of power supplies

becomes inoperative, you will hear a continuous alarm and a warning message

will appear on the display. This message is simply a notiﬁcation that the state of

the power system is no longer redundant. Use the Component Status menu to

determine which power supply has failed and identify the failed unit by the

absence of its “DC Good” LED on the PSU. Replace the failed component to

return the subsystem to a redundant state.

If you install ﬁve (5) or more disk drives and only have two (2) power supplies

installed, an alarm will sound. The Power Supply LED will illuminate steady

amber and the OCP display will indicate “Non-Redundant Power.” Install a third

power supply and the error message will clear followed by the Power Supply LED

returning to a steady green. For more information see Installing the Third Power

Supply on page 19.

Subsystem Status Icon

A feature of the CR8e OCP is the “at-a-glance” animated icon that appears to

indicate subsystem status. The icon will appear at the Main menu screen after 30

seconds of no OCP input activity and provides an “at-a-glance” look at system

status. The icon will be located where the cursor normally appears.

The animated icon will have a “happy” face and looks “left and right”, if all the

systems are operating normally. If an abnormality occurs within the subsystem,

the icon will change to a “sad” face requesting your attention.
