Frequently asked questions
What is the difference between an open-frame rack and an enclosed cabinet?
An open-frame rack has no doors or side panels, maximizing airflow and access, while an enclosed cabinet adds doors and panels for security and dust protection. Open frames suit cooling-focused setups; cabinets suit secure server rooms.
How many rack units (U) do I need?
Count the U height of each device you plan to mount and add room for growth and cable management. A 12U rack suits small setups, while 42U to 45U racks fit larger server and networking deployments.
Can I wall-mount a server rack?
Yes. Wall-mount racks like the NavePoint 12U are designed to hold networking gear and small servers off the floor, which is ideal for offices with limited space.
What weight capacity should I look for?
Match the rack’s static and dynamic capacity to the combined weight of your equipment. Enclosed cabinets like the APC NetShelter SX support heavier loads than most compact open-frame or wall-mount racks.
