Do I need to check the location of the cable entry holes when choosing a network cabinet?

When choosing a network cabinet, it is important to check the position of the incoming holes, as it directly affects the convenience, safety, and overall layout of the cabinet for wiring. The following is a point by point introduction:

1. Ensure easy entry and exit of cables
Network equipment needs to be connected to a large number of power cords, network cables, optical fibers, etc. A reasonable position for the inlet holes can facilitate the connection of cables from the outside to the inside of the cabinet.
If the position of the inlet hole is not reasonable, it may cause the cable to stretch and bend, affecting transmission performance and service life.

2. Common positions of inlet holes
Top inlet hole: suitable for wiring structures in computer rooms that run from suspended ceilings or overhead cable trays.
Bottom entry hole: suitable for wiring from under the floor (underfloor cabling system), commonly used in data centers.
Rear or side entry holes: provide more flexible wiring options, suitable for specific devices or spatial structures.

3. Match with the on-site environment
When selecting a cabinet, it is necessary to choose the position of the inlet hole at the top or bottom according to the cable routing at the installation site to avoid rework.
For example, if the computer room uses overhead cable trays, priority should be given to cabinets with large inlet holes on the top.

4. The size of the inlet hole should be large enough
The size of the inlet hole should be able to accommodate the required number and type of cables, avoiding cable crowding, overheating, or damage.
For large-scale cabling or multi fiber access, cabinets with large areas or multiple inlet ports should be selected.

5. Is there a closed cover or sealing strip
The inlet hole design with detachable cover or sealing strip helps prevent dust and insects, and keeps the interior of the cabinet clean.
Unused inlet holes can be sealed to improve safety and heat dissipation efficiency.

6. Easy to maintain and expand in the later stage
A reasonable layout of cable entry holes makes the cable arrangement more neat, making maintenance, inspection, and replacement of cables more convenient in the later stage.
It is also beneficial for future wiring expansion when adding devices, without the need for additional openings or adjustments.

7. Better coordination in cable management
A reasonable position for the incoming cable holes can better coordinate with the cable management racks, cable trays, tie loops, and other accessories inside the cabinet, achieving professional level cable organization.
