CompTIA A+ Core 2 (220-1202)Operational ProceduresMedium
A technician is installing a new rack-mounted server in a data center. Before sliding the server into the rack, the technician should ensure that the rack's grounding strap is properly connected. What is the primary safety reason for this action?
- ATo provide a safe path for fault currents and prevent electrical shock.
- BTo reduce static electricity buildup on the technician's body.
- CTo prevent electromagnetic interference (EMI) from affecting other equipment.
- DTo ensure proper network connectivity for the server.
Show answer & explanationAnswer & explanation
Correct answer: A. To provide a safe path for fault currents and prevent electrical shock.
Grounding provides a low-resistance path for electrical currents to safely dissipate into the earth in the event of an electrical fault. This prevents dangerous voltage buildups on conductive surfaces (like the server chassis or rack) that could cause electrical shock to personnel.
Why the other options are wrong
- B. An ESD wrist strap is used to reduce static electricity buildup on the technician's body; the rack's grounding strap protects against fault currents.
- C. While grounding can help reduce EMI, its primary safety function is related to electrical shock prevention.
- D. Grounding is an electrical safety measure, not directly related to network connectivity.
Electrical Grounding
Providing a low-resistance path for electrical current to flow to the earth, protecting against electrical shock and equipment damage.
- Crucial for electrical safety
- Diverts fault currents
- Prevents dangerous voltage buildup
