Data Center Cable Standards

Infra-Team - Confluence

Purpose

This policy establishes the cabling standards for all Dartmouth College data centers. The objective is to optimize airflow, minimize clutter, and simplify ongoing maintenance in the data center. This policy provides guidelines for color coding, appropriate cable lengths, and effective management practices to ensure consistency.

Scope

This policy applies to all data center personnel and contractors involved in the installation, maintenance, and removal of cabling at any Dartmouth College data center.

Guidelines

Removal of Unused Cables

  • Prior to adding new cables, review existing cables and identify any unused or obsolete cables.
  • Remove all obsolete cables from racks, overhead trays, and underfloor pathways.

Color Coded Cabling Standards

Note: To ensure consistency and ease of identification, follow the color-coded scheme below.

Note: For any new cabling requirements that fall outside of the existing color scheme, please seek approval from the Data Center Coordinator.

  • Green - IPMI Connections
  • Yellow - DCIM Connections
  • Blue - 10G Network Connections

Proper Cable Lengths

  • Gauge the required cable length for the intended connection including a small allowance for flexibility and adjustments.
  • Select the appropriate cable type based on network requirements and follow color coded cabling standards mentioned above.
  • Avoid using excessively long cables as they cause clutter and impact airflow.

Cable Management

  • Use Velcro for bundling cables in rack and, if available, utilize cable managers installed in racks.
  • Match the flow of existing cables in the rack and avoid tight angles or kinks that can degrade performance.

Compliance and Review

  • The Data Center Coordinator is responsible for ensuring all cabling adheres to the standards outlined in this SOP.
  • Regular audits will be performed to review compliance and identify any issues or potential improvements.
