Proper Vertical Rack Cable Management Solutions

Updated on Feb 26, 2021 by

Rack cable management (RCM) is one of the most pressing challenges encountered by most network installers and IT technicians in server rooms and data centers. It contains six different parts: horizontal cable management, vertical cable management, overhead cable tray systems, copper or fiber patch panel, labeling and cable ties. These parts are combined together to create an innovative and complete system for patch cable management. Today’s topic will focus on vertical rack cable management.

Vertical Rack Cable Management

Why Is Proper Vertical Rack Cable Management Important?

Rack cabling system is the lifeline of IT operations. Any poor cable management can result in catastrophic cable damage or link failure, such as signal interference and crosstalk, excess power and data cabling, cooling and airflow restriction, etc. The vertical rack cable management is no exception. From this standpoint, proper vertical cable management within the server rack will deliver a number of benefits that will assure the accuracy and efficiency of data transmission and improve system performance.

Benefits of Vertical Cable Management:

(1) Reduce Signal Interference

Proper rack cable management will separate power and data cables within the racks, which greatly decrease the chance for crosstalk and interference between power and data cables. Accordingly, it can enhance system performance.

(2) Avoid Unnecessary Cable Damage

The chance of cable damage can be usually ascribed to improper bends, movement or sharp edges. Most vertical cable management fingers can maintain cable bend radius within the ranges specified for the type of cable being used. And some high-density vertical cable manager with removable cover can protect the cable from sharp edges or dust.

(3) Improve Cooling and Airflow

It is important to make sure that cables are not placed in such a way that they restrict airflow from components inside the server rack. Cooling efficiency within the rack can be enhanced by vertical cable manager that eliminate the airflow blockage.

(4) Reduce Costs

When vertical rack cable management with bend radius fingers is used with angled patch panel directly, it can eliminate the usage of horizontal cable management panel. So best value for money is usually achieved through vertical cable managers.

(5) Improve Aesthetics

Vertical cable manager is most often used with horizontal cable manager, which provide a vertical pathway for cable bundles. Every cable is neatly in its place that can improve the aesthetics of a data center.

Vertical Rack Cable Management: Where to Start with?

When it comes to vertical rack cable management, it is important to secure, bundle and route the cables within server racks without sacrificing the server rack space. Vertical cable managers provide a vertical pathway for large volumes of cables from the switch to patch panel in the rack system. They allow multiple horizontal cable managers to feed into a large vertical pathway. So they are generally designed with height sizes up to 48U and wide up to 10 inches. The 3” and 5” wide are the most prevalent. Moreover, the vertical cable managers come in metal and plastic.
