Desk synopsis

Swapping PSUs is easy until the aisle is loud and the PDU graph twitches. This bootcamp chains micro-drills: load stepping, velcro discipline, and verbal callouts borrowed from stage crews. You leave with a laminated choreography card sized for rail clips.

Lab inclusions

  • Dual-feed PDU benches with audible overload cues
  • Velcro and strain-relief scoring rubric
  • Buddy mirror protocol for left/right dominant techs
  • Spare harnesses color-coded to RackForge standards
  • Slow-motion video review of each swap pair

Outcomes

  1. Complete a redundant swap under eight minutes without silence gaps
  2. Document cable relief before closing the bezel
  3. Spot asymmetrical draw signatures before alarms fire

Participant notes

The velcro rubric sounds silly until you realize how many swaps fail from cable tug alone.
