The vector stencils library "Rack diagrams" contains 55 hardware symbols for creating the server rack layout diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. Each module has a front panel that is 19 inches wide, including edges or ears that protrude on each side which allow the module to be fastened to the rack frame with screws. Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack mounted system, a rack mount chassis, subrack, rack mountable, or occasionally simply shelf. The industry standard rack cabinet is 42U tall." [19-inch rack. Wikipedia]
"A rack unit, U or RU is a unit of measure that describes the height of equipment designed to mount in a 19-inch rack or a 23-inch rack. The size of a piece of rack-mounted equipment is frequently described as a number in "U". For example, one rack unit is often referred to as "1U", 2 rack units as "2U" and so on.
A typical full size rack is 42U, which means it holds just over 6 feet of equipment, and a typical "half-height" rack would be 18-22U, or around 3 feet high." [Rack unit. Wikipedia]

Server rack diagrams visualize the the rack mounting of computer and network equipment as the drawing of frontal view of the rack with equipment installed. They are used for choosing the equipment or racks to buy, and help to organize equipment on the racks virtually, without the real installation.
"A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. Each module has a front panel that is 19 inches (482.6 mm) wide, including edges or ears that protrude on each side which allow the module to be fastened to the rack frame with screws." [19-inch rack. Wikipedia]
"A rack unit, U or RU is a unit of measure that describes the height of equipment designed to mount in a 19-inch rack or a 23-inch rack. The 19-inch (482.6 mm) or 23-inch (584.2 mm) dimension refers to 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 (4.445 cm) high.
The size of a piece of rack-mounted equipment is frequently described as a number in "U". For example, one rack unit is often referred to as "1U", 2 rack units as "2U" and so on.

Electrical Symbols — Switches and Relays

In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.

26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.

SWOT Template

The "SWOT Analysis" solution gives simple visual support for all the steps of a SWOT Analysis process. SWOT analysis is a strategic planning method used to evaluate the Strengths, Weaknesses, Opportunities, and Threats facing a project. The new template for ConceptDraw MINDMAP visually supports identifying internal and external factors that are favorable and unfavorable. When the analysis is complete, output your data to a SWOT Matrix in ConceptDraw PRO for exporting to a variety of other formats: MS Visio, PowerPoint presentation, PDF, image files, etc.

Security Plans

No security system cannot be constructed without detailed security plan, or even a set of plans in some cases. ConceptDraw PRO software offers the Security and Access Plans Solution from the Building Plans Area to help you design the Security Plans for any premises and of any complexity.
