In buildings, fiber-optic and copper cabling for data communication is routed between floors or sections in cable trays. They are terminated in IT racks at patch panels enabling connection with active devices via patch cables.

In exteriors, in general, we deal with fiber-optic cabling, which is usually laid under the ground or carried above the ground (shorter distances). In the event, where linking to outdoor devices is necessary (e.g. cameras or stations for IT signal routing), the fiber-optic cables are terminated in panels located in outdoor IT cabinets. For that reason, they have to resist the effects of weather, but also vandalism.

Requirements for IT racks differ depending on their placement but also by their usage. Accordingly, IT racks for basic LAN applications have different mechanical and user requirements than IT racks for data centers.

LAN and DC racks

In a LAN environment, main requirements are:

  • Height: to house all IT equipment needed
  • Depth: to fit all kinds of equipment, even the deeper ones like UPS or servers
  • Width: to accommodate all installation cables in the IT switchboard

In the case of IT racks for DATA CENTERS, in addition to the fundamental dimensional requirements, completely new ones have to be considered:

  • Possibility to place and separate multiple clients in one IT rack
  • Possibility to separate cooled and heated air to reduce energy costs
  • Possibility to integrate other technologies, like row based cooling units, UPS, electromechanical locking systems and more

Airflow control in / around IT racks

The separation of cooled and heated air is an essential method of efficient cooling of active devices in DATA CENTERS. When airflow is directed towards the front side of the active devices, it is not mixed with the heated air coming from the rear side, and thus cooling system operates at a lower output and consequently consumes less energy.

Fiber and copper links

The active devices in DATA CENTERS are installed in significantly higher densities than in a LAN environment. Accordingly, fiber and copper connections have to mirror this density. To cover this need, high-density patch panels and fiber trays are used, with a densities up to 192 LC connections in 1U height or fiber-optic connectors MPO/MTP. 12 optical fibers are terminated in single MPO/MTP connector.

Cable trays

Cable supporting systems are designed to provide a safe, easy-to-use and cost-effective cable management solution that allows the interconnecting devices, and at the same time providing physical protection and safe radius bend.

Wire mesh cable tray are considered as most universal solution. They provide a great degree of flexibility while having the same load capacity as steel metal cable trays.

For fiber optic cables in data centers special plastic cable trays are used. All corners, elbows and cross piece are rounded to guarantees the prescribed bending of fiber-optic cables.

Remote access to active devices

For various reasons (for example, security risks at data center entrance or geographical network distribution) it is occasionally not possible or effective for the user to physically access their servers or switches; therefore administration is executed via remote access, KVM switches. Devices can be remotely controlled up to the BIOS level, displayed at resolution up to 4K.
