What does "U" mean?
U (rack unit) is the height standard for network equipment. 1U is about 44.5 mm. A 4U rack has roughly twice the inside height of a 2U rack, so it holds more devices and gives more room for air to flow.
Tips
- If you are unsure, take the next size up. Extra space means better cooling and room to add a device later.
- Keep the rack where air can move around it. Do not block the vents.
- All NEXELTRON racks have multi-level ventilation, a lockable front door and cable entry at both top and bottom.
