3.4. Physical Installation Factors

💡 First Principle: Networks need physical infrastructure—equipment requires space, power, cooling, and organized cabling. Ignoring physical requirements leads to equipment that overheats, can't get enough power, or creates cable management nightmares that slow troubleshooting.

Think of physical installation like building a house: you don't just buy furniture (equipment)—you need electrical, plumbing, HVAC, and structural planning. Skipping these leads to failures that no amount of configuration can fix.

What breaks without proper planning: Servers throttle performance due to overheating. Switches crash during power flickers because nobody installed a UPS. Troubleshooting takes hours because unlabeled cables turn a 5-minute fix into a full-shift nightmare.
