cleaning it.
Component Time Frame Maintenance Procedure
Keyboard Regularly Dust with damp, lint-free cloth.
Monitor screen Regularly Use "HP Video Screen Cleaning Solution" found in 92193M
Master Clean Kit.
Mouse Regularly Refer to the mouse's manual for mouse maintenance
procedures.

benzene, trichlorethylene, ammonia, dilute ammonia, or acetone, as these
chemicals could damage the keyboard's plastic surfaces.
HP recommends the periodic cleaning of tape heads, capstans, and guides on these products: tape drive
units and those products using high-density data cartridges and mini-data cartridges. This procedure
prolongs tape/head life and helps reduce read/write errors due to dust and oxide buildup.
HP NetServer Troubleshooting Tips
Use topic provides a list of troubleshooting tips specifically suited for the HP NetServer LC 2000. These tips
address the most common reason for system problems.
The System Will Not Power Up
1. Ensure the power supply module(s) is/are properly seated.
NOTE The HP NetServer LC 2000/LC2000r has a 15 second delay after power is initially
applied and will not respond to the front panel controls during this time period while it
performs self-test.
2. Verify power is available at the AC power receptacle.
The green LED for each supply should be off when the power is off and the system is in
standby.
NOTE There is a standby LED on the system board, which glows green when AC power is
applied and can be seen from the rear of the NetServer.
3. Verify the power source is 120 VAC, nominal.
4. Verify the AC power circuit breaker is closed.
