In my years of experience, seeing a sloppy server closet with wires hanging all over the place shows poor infrastructure maintenance. And a technician not concern on wire management alarms me. Cable management is a simple task to do on a daily basis. Not doing it properly or carelessly leaving wires hanging all over the place is an accident ready to happen.
When there is down time the company loses money, when money is lost in most cases it is never recovered. And a server being shut off because of a loose wire or being pulled is not proper cable management.
As a Network Administrator you should be aware of your server closet and keep daily cables labeled and organized. Doing so will help you be better organized when problems occur.
