Humidity and dew point are outside equipment-safe limits. That does not establish the rack mixes opposing intake and exhaust patterns.

The supposedly redundant devices share one power failure domain. That does not establish the rack mixes opposing intake and exhaust patterns.

Electrical distribution must stay within safe capacity and code. That does not establish the rack mixes opposing intake and exhaust patterns.

Placing core devices in controlled lockable racks and rooms with visitor logs would not install a UPS with calculated watt load and required runtime.

Connecting independent power feeds and UPS paths where available would not install a UPS with calculated watt load and required runtime.

Control temperature and relative humidity to vendor and site design limits would not install a UPS with calculated watt load and required runtime.

Access controls and recorded attempts verify physical security. It does not run a supervised transfer test and time supported switch operation.

Communication between different IP subnets requires a routed interface or gateway rather than Layer 2 bridging alone. Verification of this result involves running a supervised transfer test and time supported switch operation.

Measure steady and peak amp draw after rebalancing. It does not run a supervised transfer test and time supported switch operation.

Physical access to network infrastructure is uncontrolled. That does not establish a power distribution unit does not itself provide battery backup.

The supposedly redundant devices share one power failure domain. That does not establish a power distribution unit does not itself provide battery backup.

Humidity and dew point are outside equipment-safe limits. That does not establish a power distribution unit does not itself provide battery backup.

Connecting independent power feeds and UPS paths where available would not recalculate circuit and PDU draw, rebalance and install adequately rated feeds.

Control temperature and relative humidity to vendor and site design limits would not recalculate circuit and PDU draw, rebalance and install adequately rated feeds.

Arrange compatible airflow directions and cold/hot aisles with blanking panels would not recalculate circuit and PDU draw, rebalance and install adequately rated feeds.

Communication between different IP subnets requires a routed interface or gateway rather than Layer 2 bridging alone. Verification of this result involves measuring steady and peak amp draw after rebalancing.

Access controls and recorded attempts verify physical security. It does not measure steady and peak amp draw after rebalancing.

Stable readings above condensation risk validate environmental control. It does not measure steady and peak amp draw after rebalancing.

The supposedly redundant devices share one power failure domain. That does not establish the outlet distribution plan is overloaded.

Humidity and dew point are outside equipment-safe limits. That does not establish the outlet distribution plan is overloaded.

Physical access to network infrastructure is uncontrolled. That does not establish the outlet distribution plan is overloaded.

Using floor-level IDFs linked by suitable backbone to the MDF would not implement unique labels and maintain patch-to-switch port maps.

Providing controlled fiber routing and minimum bend radius in the distribution panel would not implement unique labels and maintain patch-to-switch port maps.

Placing core devices in controlled lockable racks and rooms with visitor logs would not implement unique labels and maintain patch-to-switch port maps.

Optical transceiver compatibility and receive-light measurements diagnose the physical signal path before higher-layer work. It does not use a toner and cable map to verify the wall outlet end-to-end.

Certify longest horizontal cables and check closet uplink lengths. It does not use a toner and cable map to verify the wall outlet end-to-end.

Access controls and recorded attempts verify physical security. It does not use a toner and cable map to verify the wall outlet end-to-end.

Optical transceiver compatibility and receive-light measurements diagnose the physical signal path before higher-layer work. That does not establish patch panel and outlet labels are incomplete.

The physical distribution layout exceeds horizontal link reach. That does not establish patch panel and outlet labels are incomplete.

A power distribution unit does not itself provide battery backup. The missing change involves patch panel and outlet labels are incomplete.

Implementing unique labels and maintaining patch-to-switch port maps would not provide controlled fiber routing and minimum bend radius in the distribution panel.

Arrange compatible airflow directions and cold/hot aisles with blanking panels would not provide controlled fiber routing and minimum bend radius in the distribution panel.

Connecting independent power feeds and UPS paths where available would not provide controlled fiber routing and minimum bend radius in the distribution panel.
