Patch Cable Colour Specification

Overview​

This document outlines the standardized color-coding scheme for patch cables used in our organization's network infrastructure. Adhering to this specification ensures efficient identification and management of various devices within the network. This scheme applies to all areas including workstations, VOIP systems, wireless networks, security systems, building management systems (BMS), audiovisual equipment, and server connections.

Colour Coding System​

The color-coding system classifies cables based on the type of device they connect to. This facilitates quick identification, reduces the chance of errors during troubleshooting and maintenance, and enhances overall network organization. Below is the detailed specification:

1. Workstations and Printers​

  • Color: Blue
  • Application: This color is used for patch cables connecting workstations, desktops, laptops, and printers to the network.

2. VOIP Controller and Dedicated VOIP Handsets​

  • Color: Black
  • Application: Black cables are designated for VOIP controllers and dedicated VOIP handsets, ensuring clear differentiation from standard data devices.

3. Digital/Analog Handsets​

  • Color: Beige
  • Application: Beige cables are used for connecting both digital and analog handsets, distinguishing them from VOIP devices.

4. Wireless Access Points​

  • Color: White
  • Application: White cables are reserved for connections to wireless access points, aiding in the swift identification of wireless network infrastructure components.

5. Security Devices (CCTV, Access Control)​

  • Color: Red
  • Application: Red cables are utilized exclusively for security-related devices such as CCTV cameras and access control systems.

6. BMS Devices (Solar, Environmental, etc.)​

  • Color: Grey
  • Application: Grey cables are allocated for building management systems, including but not limited to solar controllers and environmental monitoring systems.

7. Audiovisual​

  • Color: Purple
  • Application: Purple cables are used for audiovisual equipment connections, segregating AV network traffic from other data types.
  • Color: Pink
  • Application: Pink cables are designated for switch uplink connections. Note that Direct Attach Copper (DAC) cables are exempt from this color requirement.

9. Carrier NTU/Modem to Router/Firewall​

  • Color: Yellow
  • Application: Yellow cables connect the Network Termination Unit (NTU) or modem to routers and firewalls, identifying the demarcation point between carrier equipment and internal network devices.

10. Router/Firewall to Core Switch​

  • Color: Green
  • Application: Green cables are used for connections from routers/firewalls to the core switch, delineating critical network backbone links.

11. Servers​

  • Color: Orange
  • Application: Orange cables are dedicated to server connections, facilitating quick identification of data center or server room cabling.

Implementation and Compliance​

  • All technical personnel must comply with this color specification when installing or modifying network cabling.
  • In case of special circumstances where a specific color is unavailable, clear labeling should be used as a temporary measure until the correct color cable can be sourced.
  • Regular audits will be conducted to ensure adherence to these specifications.

Adherence to this color-coding system is crucial for maintaining an organized and efficient network infrastructure. It aids in quick fault isolation, simplifies network management, and enhances the overall safety and reliability of the network.
