Ordering a
19" server- or patch cabinet

A Penn Elcom 19 inch (server) rack enables a concise, safe and efficient way to store your IT-hardware.

A 19 inch patch cabinet (more commonly referred to as wall-mount racks) is most suitable for arranging your network connections and the associated cabling. A server cabinet can also be used for this, but the biggest advantage of a patch cabinet is that its wall-mountable.

A rack cabinets mounting fixture consists of two parallel metal strips (also referred to as “posts” or “panel mounts”) standing vertically. The posts are each 0.625 inches (15.88 mm) wide, and are separated by a gap of 17.75 inches (450.85 mm), giving an overall rack width of 19 inches (482.60 mm). The posts have holes in them at regular intervals, with both posts matching, so that each hole is part of a horizontal pair with a center-to-center distance of 18.312 inches (465.12 mm).

Penn Elcom 19 inch server rack cabinets are, by default, equipped with four vertical posts. The holes in the posts are arranged vertically in repeating sets of three, with center-to-center separations of 0.5 inches (12.70 mm), 0.625 inches (15.88 mm). The hole pattern thus repeats every 1.75 inches (44.45 mm).

All about
rack dimensioning

All rack panels by Penn Elcom have a default width of 19 inch and an increasing height depicted in number of Rack units, RU or U.

A rack unit, U or RU as a unit of measure describes the height of electronic equipment designed to mount in a 19 inch rack. The 19 inches (482.60 mm) or 23 inches (584.20 mm) dimension reflects the width of the equipment mounting-frame in the rack including the frame; the width of the equipment that can be mounted inside the rack is less. One rack unit is 1.75 inches (44.45 mm) high.

A rack panel or filler panel in a rack is not an exact multiple of 1.75 inches (44.45 mm). To allow space between adjacent rack-mounted components, a panel is 1⁄32 inch (0.031 inch or 0.79 mm) less in height than the full number of rack units would imply. Thus, a 1U rack panel would be 1.719 inches (43.66 mm) high. If n is number of rack units, the formula for panel height is h = (1.750n − 0.031) for calculating in inches, and h = (44.45n − 0.79) for calculating in mm.

The rack unit size is based on a standard rack specification as defined in EIA-310. The Eurocard specifies a standard rack unit as the unit of height; it also defines a similar unit, horizontal pitch (HP), used to measure the width of rack-mounted equipment.

By confirming equipment dimensions to this 19" standard it’ll become possible to stack a considerable amount of equipment in a fairly tight space. Furthermore it’ll be easy to estimate the required amount of space to house your configuration.
