Power & PoE Distribution

Scope

Section titled “Scope”

Power distribution from cabinet PDUs to network backbone and per-tile PoE delivery.

Deployed Facts

Section titled “Deployed Facts”
  • Cabinet architecture document lists multiple PDUs feeding server/switch/midspan groups.
  • Midspan inventory is documented as mixed PD-9624GC and PD-9612GC units.
  • Tile PoE board documentation targets IEEE 802.3bt support and multi-output power rails.
  • PoE board design includes class selection (DIP/classification), USB-C output, and auxiliary outputs.
  • Hardware docs include class-board variants for class 4/5/8 profiles.

Server Cabinet Connections

Section titled “Server Cabinet Connections”

This diagram shows what is connected to each PDU and includes management IP annotations.

Server cabinet connections

Interfaces

Section titled “Interfaces”
  • Upstream: PDUs and cabinet feeds.
  • Lateral: switch-to-midspan-to-tile chain.
  • Downstream: RPi/SDR and optional peripherals via PoE board connectors.

Constraints and Risks

Section titled “Constraints and Risks”
  • Power class mismatch can cause PSE shutdown under load.
  • PoE board revisions exist (V1.x artifacts), so exact deployed revision must be tracked per tile.
  • Cabinet-level changes require synchronized updates in network and switchport docs.

Depends On

Section titled “Depends On”
  • Stable physical cabinet and cable routing.

Provides To

Section titled “Provides To”
  • Network switch and midspan operation.
  • Tile node bring-up (RPi/SDR/peripherals).
  • Timing and acquisition systems availability.

Critical Paths

Section titled “Critical Paths”
  • PDU availability directly gates switch/PTP/DAQ availability.
  • Midspan uplink and classification settings gate tile boot stability.
