The value of the transceiver rack is not just neatness, but centralized management of power supply, heat dissipation, and lightning protection and grounding. Taking the 14-slot box rack as an example, the following three layouts must be clearly calculated before installation, so that later operation and maintenance can only replace the machine without rework.
Calculate the total power supply first, and then determine the number of racks
- The power consumption of a single transceiver is usually 2 to 5 watts, and a full slot of fourteen transceivers, together with the heat dissipation of the rack itself, can be controlled to about a hundred watts, as specified on the nameplate.
- The centralized switching power supply leaves an additional 30% capacity margin according to the actual measured load. When the rack is full, high-power consumption models will no longer be superimposed.
- Computer rooms with capacity expansion plans should be budgeted as double racks, and the power supply lead-out point and grounding point of the second unit should be reserved in advance.
Slot arrangement and airflow
Equipment at the same remote end should be placed in adjacent slots together. When fibers are broken, it is fastest to check by area. Blind boards should be installed in empty slots to avoid cold air short circuits. Leave 1U of space at the top and bottom of the rack in the cabinet, away from heat sources such as power modules;14-slot box transceiver rackIt supports two wiring directions, front and rear. Determine the direction before installation, and then label the slots uniformly. Follow the diagram to find out later.
Lightning protection and grounding
The rack shell should be reliably connected to the grounding copper bar of the computer room with a ground wire. When the outdoor optical cable enters the computer room, it must be terminated through the distribution frame and then jump to the equipment. Do not allow external metal parts to enter the cabinet. In strong electromagnetic environments such as substations and photovoltaic stations, it is recommended to carry out optical isolation transformation simultaneously.

The layout is done at the front, and troubleshooting is reduced to the manual work of changing machines according to the light. The rack power extraction method and capacity calculation can be confirmed by contacting EB-LINK technical support at 0755-83179002.
