An animated icon will appear on the display after 30 seconds of no OCP input
activity and provides an “at-a-glance” look at system status. When a “happy”
animated face appears, all systems are indicating a nominal state. When the
animated face changes to a “sad” face, the system indicates that a problem has
been detected and requires attention.
The “power system” status will display the total power available per drive slot in
redundant and non-redundant mode. A maximum supported value of 30 watts
per drive bay is available in either mode. Also the user can view individual power
supply status and configurations.
The OCP displays information on each cooling fan’s speed. Each fan’s speed
(RPM) is controlled via the internal cabinet thermal monitoring system,
referenced from a user-established temperature threshold. Cabinet temperature is
measured within the drive bay area between drive slots 2 and 3, and between slots
7 and 8. By sensing cabinet temperature in these locations, the system provides
the most sensitive measurement for maximum protection. The temperature is
displayed in both Celsius and Fahrenheit. The SAF-TE processor monitors the
performance of each fan via tach pulses which track the speed (RPM) of each fan
impeller.
LEDs
Power-On LED
The Power-On LED signifies that the CR8e system has power applied.
Status Indicator LEDs
There are three Status Indicator LEDs to assist the user in determining the current
state of the CR8e subsystem. The following subsections describe each LED.
Channel Mode
The Channel Mode LED indicates the status of the subsystem array by changes in
its color and state. Steady green indicates normal array activities.
When the LED changes to amber (flashing or steady) it indicates abnormal
activities. For more information see LED Descriptions on page 39.
