Why it exists
A data center depends on a chain of mechanical and electrical systems, and any link can fail without an external cause. A cooling pump seizes, a switchgear component arcs, a UPS battery string fails or a generator does not start. Property forms are built for perils such as fire and wind and generally exclude losses from the internal breakdown of machinery, so without equipment breakdown cover the cost of these events can fall on the operator.
What it typically pays for
Coverage usually includes the cost to repair or replace the failed equipment, damage to other property caused by the breakdown, and expediting expenses to speed up repairs. Many forms add coverage for loss of income and extra expense when the breakdown interrupts operations, which can be the largest part of the loss in a facility with contractual uptime commitments.
- Generators and fuel systems.
- Uninterruptible power supplies and battery systems.
- Switchgear, transformers and power distribution units.
- Chillers, pumps, cooling towers and in row or liquid cooling equipment.
- Building automation and controls.
Why AI density raises the stakes
Higher rack density concentrates more heat and power in a smaller space, and it leaves less margin when a cooling or power component fails. Uptime Institute notes that modern AI racks can draw many times the power of a traditional rack, which increases how quickly a cooling failure can damage equipment. Underwriters ask about redundancy, maintenance programs and monitoring for that reason.
What underwriters will ask for
Expect to describe the redundancy of your power and cooling, such as N plus one or two N designs, the age and maintenance history of major equipment, load testing of generators, thermal monitoring and the response plan for a failure. Facilities with documented maintenance and monitoring generally obtain better terms. Ask your broker to review the form's exclusions, in particular any related to wear and tear, testing and the age of equipment.
