Critical Infrastructure Systems
Aside from servers, software, storage and IT networking devices, most organisations will operate several core critical infrastructure systems including:
- Power Protection: , energy storage battery packs, power distribution units and standby power generators.
- Cooling: air conditioners, condensers, air handlers, chillers and humidifiers.
- Electrical Circuits and Distribution: LV switchboards, power factor correction () systems, electrical distribution and sub-distribution boards, breakers and cable connections, automatic transfer switches, UPS bypass switch arrangements, lighting and emergency lighting.
- Energy Metering: energy metering at the distribution, sub-distribution and rack levels.
- Environment Monitoring: monitoring devices and sensors including temperature (indoor and outdoor), humidity, moisture, power, smoke, fluid and water.
- Fire Suppression: suppression agent containers, fire suppression monitoring and alarm panels, power connections/battery replacement and sprinkler systems.
- Security: the access control system at the building, room and rack level and the CCTV systems including any motion detectors and IP cameras within the server room itself; if there is no access control check the room visitor list.
Each of these critical systems will have their own maintenance requirements and require at least one (if not more) inspections per year.
