Wearing Rack and Cabinet Systems
What are the main differences between “racks” and “cabinets”?
The term “rack” is often used in the industry to describe both open-frame or relay racks as well as cabinet or rack enclosures. While these discount canada goose jackets buffalo ny provide
the same basic function, there are a number of factors to consider when deciding which is appropriate for your specific application.
Equipment: A cabinet is more appropriate for heavy servers, while a rack provides easy access to all sides of the mounted equipment.
Airflow and cooling: A rack is completely open while a cabinet needs to be able to provide sufficient airflow when ventilation is needed. Cabinets allow
for appropriate cooling management and heat removal, whereas open racks may dissipate heat uncontrollably.
Environment: If your equipment requires a dust-free environment, the extra protection that a cabinet provides is very suitable. If discount canada goose jackets buffalo ny have a very clean
and well-kept telecom center then the open convenience of a rack will fit your needs.
Aesthetics: If your telecom closet will be visible to the public, cabinets look neater than an open rack; however, there are various cable management
products that will give a rack a very neat and professional appearance.
Security: Cabinets have locking mechanisms available on their doors for added security. An open rack does not have that feature.
Questions to consider when using cabinets.
Whenever discount canada goose jackets buffalo ny need to mount network equipment (hubs, switches, bridges, routers, terminal servers, print servers, repeaters, monitors and keyboards), and
environmental protection, aesthetics and security are concerns, here are some of the basic questions you may want to be asking:
Do I already have existing cabinets in your data center or network environment?
If so, for aesthetic and logistical reasons you might want to select a cabinet from the same manufacturer.
What type of environment is the cabinet going into?
Standard equipment room – Free-standing, network and server cabinets are common.
Data center – Colocation cabinets allow compartmental access.
Limited floor space – Wall-mount cabinets often make sense.
Earthquake zone – Seismic cabinets are typically used where additional support and bracing are necessary. Standards ratings, like Bellcore Zone 4 and
NEMA are important.
Zone access – The ZCAC places the consolidation point for wiring patch panels, punch-down blocks, hubs or routers closer to the work area. This allows
for easy access for moves, adds and changes.
Factory floor – Some cabinets are designed and tested to withstand different industrial environments.
What is going into the cabinet?
The dimensions of the network equipment, cable management, climate control and power protection will dictate the cabinet, door and shelf sizes, as well
as the number of shelves.
How is the network equipment ventilated?
All network equipment generates heat, and too much heat can impact network performance. There are many climate control cabinet options, from
perforated doors to ceiling fans that ensure proper temperatures are maintained. Self-contained cooling cabinets are also highly recommended for
high-density environments that exceed 15 kW.
