On the topic of housekeeping and the exterior surfaces of server cases, which of the following measures should you implement for unused rear expansion slots?
A.
Use spray cleaners.
B.
Install blank cover plates.
C.
Configure a temperature sensor to raise an alarm.
D.
Use a cleaning agent and process that simultaneously gets rid of surface soil and reduces static charges.
Explanation:
You must install blank cover plates in unused rear expansion slots to make certain that no dust creeps into the interior of the server case. The vacuum operation of the server’s cooling fans will draw debris into the interior if there are no blank cover plates installed in unused rear expansion slots. The consequences of not installing blank cover plates is a disruption in normal airflow patterns and possible overheating of some server components. You should therefore ensure that all gaps in the back of the server case are closed or covered.
Incorrect
Answers:
A: You should under no circumstances use spray cleaners to clean anything near the ventilation slots. You might need to turn off the server when cleaning in the surroundings of the ventilation slots.
C: Temperatures sensors are usually configured to raise an alarm when the processor or the interior of the server overheats or reaches undesirable temperature levels.
D: You should use a cleaning agent and process that simultaneously gets rid of surface soil and reduces static charges when cleaning the exterior surfaces of a server case.
Remember that the more you handle a plastic server cabinet or a metal server cabinet, the more dust will gather. Bear in mind that static charges on exterior surfaces attracts dust as well.
