Organisation that affects everything.
WHY IT MATTERS
Poor cabling obstructs airflow, prevents maintenance, and causes outages during unrelated work.
WHAT GOOD PRACTICE LOOKS LIKE
Cables routed in defined paths Power and data separated Appropriate lengths, not coiled excess Both ends of every cable labelled Documented patching
WHY SEPARATION OF POWER AND DATA
Power cables can interfere with data cables running alongside them.
WHY LABELLING MATTERS MOST
In a failure, at night, nobody can trace an unlabelled cable.
WHAT TO LABEL
Both ends, with what it connects and to which port.
WHAT TO DOCUMENT
A record of every connection.
WHAT CAUSES OUTAGES
Pulling the wrong cable Disturbing adjacent connections while working Cables under tension, which work loose
WHAT TO AVOID
Cables draped across equipment Cables blocking the rear of servers Accumulated disused cables left in place
THAT LAST ONE
Remove cables when equipment is removed. Otherwise nobody dares touch anything.
WHAT TO REVIEW
Cabling condition, periodically.
