Why is labeling cables before disconnecting a defective controller important?

• A. It ensures correct reconnection later
• B. It reduces power consumption
• C. It speeds up the boot process
• D. It increases network latency

Answer: (A)

Labeling cables before disconnecting a defective controller keeps a clear map of how everything is connected so you can reconnect it exactly as it was. In a panel or rack, there are often many cables for power, data, and control signals that can look the same. Without labels, it's easy to mix them up and plug a cable into the wrong port, which can disrupt communication, cause devices to misbehave, or create unintended electrical issues. Clear labels on each end let you reattach each cable to the correct device and port, preserving the original wiring layout and reducing downtime. This also helps with future troubleshooting and documentation, since you have a record of how the system was wired. Labeling is about connection accuracy and restoring the exact configuration; it doesn’t directly change how much power the system uses, its boot speed, or the network latency once everything is reconnected correctly.
