Notes:
1. Recommended temperature range is 21 to 24°C.
2. On shipping/storage condition, the product should be packed with factory packing.
3. The above specifications of vibration are applied to all three axes.
4. See ASTM D999-01 The Methods for Vibration Testing of Shipping Containers.
5. See ASTM D5277-92 Test Method for Performing Programmed Horizontal Impacts Using an Inclined Impact
Tester.
6. See ASTM D6055-96 Test Methods for Mechanical Handling of Unitized Loads and Large Shipping Cases and
Crates.
7. Time is 5 seconds or less in case of the testing with device resonance point (6 to 7Hz).
8. When flash modules are installed in the system.
Heat output and air flow
The following table lists the heat output and air flow requirements for the P9500 disk array.
Both the control chassis and the disk chassis contain front and rear fans to circulate air through
the chassis from front to back. Air flows in through the front bezel to the rear of the component
