## Questions

### What is a rack unit?

A rack unit, written U, is a vertical space of 44.45 mm, or 1.75 in. Equipment is described by how many U it takes, so a 42U rack holds equipment totaling up to 42U in height.

### Is the 19 inches the size of the rack?

No. The 19 inches is the spacing of the mounting rails that hold the equipment, per EIA-310. The outside width of the rack is larger. Give the depth you need, because depth varies more between racks than width.

### How do I plan cooling?

Check the heat load of the equipment and the airflow direction it uses, and leave blanking panels and cable room so air moves freely. Enclosed cabinets can include fans or be sized for the room cooling. State your equipment so the cabinet can be matched.
