PDU Failover Lab: Transfer Switches Under Load
Bench critical power paths with metered scenarios so technicians rehearse safe transfers before a live incident.
What happens in the room
Participants trace feeder topology, validate metering points, and rehearse scripted failover sequences on a mirrored PDU stack. The emphasis stays on procedure discipline, witness logging, and communication cadence with the NOC. You leave with a reusable checklist aligned to common colocation runbooks.
Included focus areas
- Metered load-step exercises with instructor sign-off
- Witness log templates mapped to maintenance windows
- Parallel NOC voice bridge etiquette drills
- Breaker sequencing cards for dual-fed racks
- Thermal spot-check protocol after transfer
- Post-event metrics capture for capacity review
- Peer review of each team’s command phrases
Outcomes you can observe
- Execute a scripted transfer without improvising breaker order
- Produce an auditable witness log within five minutes of completion
- Coordinate with remote NOC using a shared vocabulary sheet
FAQ
Do we need our own PPE?
We provide arc-rated gear that fits standard Korean sizing. Bring your own boots if you prefer a specific fit.
Is lunch included?
Morning and afternoon snacks are included; lunch is self-catered so teams can keep discussing scenarios nearby.
What is not covered?
Vendor-specific firmware tuning for proprietary UPS models is out of scope; we focus on procedural readiness.
Participant notes
The failover script matched how our colo partner expects updates. I finally stopped guessing which meter reading to call out first.
Dry run on phrasing for the NOC saved us during a real maintenance slot two weeks later.
