How to route cable trays in the server room
The safest approach in any server room: use separate cable trays for power and data, with power cables routed on one side of the rack and data on the other. This eliminates the separation question entirely and makes future cable additions far simpler to plan. Poor cable routing can block airflow, increase heat buildup, and make maintenance extremely difficult. According to the ITIC 2024 Hourly Cost of Downtime Report, a single hour of unplanned outage could cost over CAD 300,000 for more than 90% of mid-size and large enterprises. Vertical Cable Management Vertical cable management routes cables vertically from the server rack's top to bottom. A structured cabling system allows for modular, easy-to-manage cable layouts.
