Applications for depth
835 mm (32.5 in.) is the preferred depth for
AV equipment.
1,070 mm (42 in.) is the standard depth and
meets most low- to medium-density applications.
The 1,195 – 1,220 mm (47 – 48 in.) depth
enclosures are becoming the new standard
because of increasing server depth crowding
cable and power space.
Applications for height
24U enclosures — Remote offices and small spaces.
42U enclosures — Standard height used globally,
designed to fit through standard doorways.
45U enclosures — Enclosures with additional
U-spaces for environments that standardize on
a 45U 1,225 mm (7 ft.) enclosure height.
48U enclosures — More U-spaces for more
equipment in the same footprint.
Applications for width
600 mm (24 in.) wide enclosures are the standard
for most server applications. For higher densities, a
deeper enclosure may be required.
750 mm (30 in.) wide enclosures offer more space
for high-capacity cable management and power
distribution. Typically, wider enclosures are used for
networking applications but the extra side space is
often requested in blade server applications.
