ƒInter-Integrated Circuit (I2C): The I2C serial bus is used to connect various temperature sensors and presence detection circuits within the chassis.

Subsystem monitoring is a necessary part of subsystem management. If failure events or other disruptive events are detected and reported, the subsystem managers must take appropriate actions to rectify the problem. Failure to act in a properly specified manner to a system event (like overheating) can cause severe and permanent damage to the subsystem.

Two (2) LED indicators are located on the right side of each drive tray. (See Figure 3-11) Refer to Table 3-2for the LED definitions. When notified by a drive failure message, you should check the drive tray indicators to find the correct location of the failed drive. Replacing the wrong drive can fail two members of a logical array (RAID 3/5) and thus destroy data in the array.
