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.  

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 Checklist

Begin with the procedures in this section as the first step in troubleshooting a problem with the server. 

Server Does Not Power On

Follow these steps if the power/activity light does not light green after you press the power-on button.    

1. Remove the AC power cord, wait 15 seconds, reconnect the power cord, and try again. 

2. Verify all cables and power cords are firmly plugged into the respective receptacles.

3. Select the correct setting on the voltage switch located beside the power connector on the rear panel.

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.

Tape drive heads 

Monthly

Use “Magnetic Head Cleaning 
Solution” found in the 92193M 
Master Clean Kit.

Cooling fans and 
grilles

6 Months

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).

NOTE

A system hang (Server does not complete boot process) could 
be due to an improperly installed heat sink on the processor. If 
the heat sink is not properly installed on the processor, the 
processor may overheat causing intermittent or unreliable 
operation leading to a possible system crash and permanent 
damage to the processor
