8.1.1Cooling Element Sensors

There are two fans in each power supply module. The normal range for fan speed is 4000 to 6000 RPM. Cooling element failure occurs when a fan’s speed drops below 4000 RPM.

Set up an IP address for the controller 5.1.1 Point-to-Point Configuration Guidelines Caution - If you keep the default loop mode and connect to a fabric switch, the array automatically shifts to public loop mode. As a result, communication between the array and the switched fabric runs in half duplex send or receive instead of providing the full duplex send and receive performance of point-to-point mode 5.1.2 A Sample SAN Point-to-Point Configuration Remember these important rules Map LG1 to SIDs 45 and Note - These illustrations show the default controller locations however, the primary controller and secondary controller locations can occur in either slot and depend on controller resets and controller replacement operations 2.
