Chapter 6 Troubleshooting Preventive Maintenance Procedures Refer to the following table for preventive maintenance procedures used for the HP Server tc2120. Be sure to turn off power to the server when cleaning it. Component Keyboard Monitor screen Time Frame Regularly Regularly Mouse Regularly Tape drive heads Monthly Cooling fans and grilles 6 Months Maintenance Procedure Dust with damp, lint-free cloth. Use "HP Video Screen Cleaning Solution" found in 92193M Master Clean Kit. Refer to the mouse's manual for mouse maintenance procedures. Use "Magnetic Head Cleaning Solution" found in the 92193M Master Clean Kit. Check cooling fan operation and clean the air intake openings on the chassis by removing any dust, lint, and other obstructions to airflow. CAUTION Do NOT use petroleum-based cleaners (such as lighter fluid or cleaners containing benzene, trichlorethylene, ammonia, dilute ammonia, or acetone. These chemicals could damage the keyboard's plastic surfaces). HP recommends the periodic cleaning of tape heads, capstans, and guides on HP tape drive units and those products using high-density data cartridges and mini-data cartridges. These maintenance procedures prolong tape and head life and helps reduce read/write errors due to dust and oxide. Troubleshooting WARNING Before removing a cover, always disconnect the AC power cords. Disconnect them to avoid exposure to high energy levels that may cause burns when parts are short-circuited by metal objects such as tools or jewelry. Disconnect the telephone cables to avoid exposure to shock hazard from the telephone ringing voltages. WARNING Do NOT operate the HP Server for more than 10 minutes with any cover (including power supplies and disk drives) removed. Otherwise, damage to system components may result due to improper cooling airflow. However, you can safely remove a cover while the HP Server is running to remove and replace PCI hot-plug boards. For any other service activity requiring access to the system board or power distribution board, power down the HP Server and observe all safety precautions. For problems with the disk array controller board, refer to the appropriate HP NetRAID manual. For problems with the HP Instant Toptools, refer to the HP Instant Toptools Administrator Guide on the HP website at: www.hp.com/toptools 2
