Length and capacity are separate acceptance checks

A fictional floor design specifies a maximum ninety-metre permanent copper link and a maximum one-hundred-metre complete channel for this exercise. The documented route to one desk is eighty-four metres, and the two approved patch cords are five metres each. A second route is ninety-three metres before patch cords are added. The project also contains four powered access points, each with a supplied maximum demand of eighteen watts, and the chosen switch allocates only sixty watts to that group. A supplier says every cable is new, so both the cabling and power design should pass automatically. The review concerns only the supplied figures and the need for evidence. It does not certify a real installation, specify a universal fire clearance or authorize work on electrical circuits.

1. Check the first and second channel against the supplied length model.

Read the worked answer

The first permanent link 84 m and complete channel 94 m pass those two length limits. The second permanent link 93 m already exceeds 90 m, regardless of patch cords. Passing length alone is not a complete cable certification.

2. Check the stated power demand and identify a handover need.

Read the worked answer

Four times 18 W is 72 W, exceeding the supplied 60 W allocation by 12 W. Reconcile the actual power classes, budget and operating requirements, and provide verified link/power tests and as-built ownership before acceptance.
