Validation Rules

Rule Name	Category	Severity	Description
PDU Power Capacity (80% Rule)	Rack	Error	Rack power load must not exceed 80% of PDU capacity to maintain safe headroom
Rack Ventilation Spacing	Rack	Warning	Rack must include 1U ventilation panel between heat-generating devices such as amplifiers and encoders
Rack Floor Load Compliance	Rack	Error	Fully populated rack weight must not exceed the rated floor load of the installation environment
Cable Management Reserve	Rack	Warning	Rack must have minimum 2U reserved for horizontal cable management panels
UPS Bottom Placement	Rack	Info	UPS unit must be positioned at the bottom of the rack to maintain low center of gravity
Circuit Capacity Compliance	Power	Error	Total system power draw must not exceed the rated capacity of the dedicated circuit
PoE Switch Budget	Power	Error	Aggregate PoE device power draw must not exceed the total PoE budget of the switch
PDU Headroom Requirement	Power	Warning	PDU must support 20% headroom above calculated total load for expansion and safety
Mission-Critical Redundant Power	Power	Warning	Redundant power feed and UPS protection required for mission-critical AV systems
Dante Dedicated VLAN	Network	Error	All Dante audio-over-IP devices must be isolated on a dedicated VLAN separate from corporate traffic
IGMP Snooping for AV-over-IP	Network	Error	Multicast IGMP snooping must be enabled on all switches carrying AV-over-IP multicast traffic
PoE Class Match	Network	Error	Network switch port PoE class (802.3af/at/bt) must match the power requirement of the connected device
QoS for Real-Time AV	Network	Warning	QoS DSCP markings must be configured to prioritize real-time AV traffic on all managed switches
DM-NVX Redundant Network Path	Network	Warning	Redundant network path required for Crestron DM-NVX deployments in mission-critical spaces
HDMI Cable Length Limit	Cable	Error	Passive HDMI cable length must not exceed 15m; extender or active cable required for longer runs
Cat6 Horizontal Run Limit	Cable	Error	Cat6 horizontal cable runs must not exceed 100m per TIA-568 standard
HDBaseT Cable Length Limit	Cable	Error	HDBaseT signal extension over Cat6A must not exceed 100m for 4K/HDR signal integrity
