Major Changes to Rack Power Distribution:

Not enough kVA available

Rack uses ~1kVA (1KW)

Existing infra has capacity of 2.8kVA, but packs are dated and keep throwing errors and eating batteries.

Dual Dell Branded 2kVA Rackmount UPS Units, EATON Whitelabel Units.
_{Concern regarding these use 20a C19 plugs, but bought cheater cord(s) 😝}

Give Koopa old-ass batteries, hoping to reuse? Idk.

20a Service Switchover:

New UPS setup (if I add more servers) requires 20a service to outlet.

This in-turn requires a complete gut-job of existing 15a service wiring to existing outlet:

Logic / Steps:

• De-energize circuit (flip breaker)
• Pull-out UPS plugs (we'll save this for later)
• Pull 15a wiring
• Replace w/20a Wiring (30ft should suffice, pre-route this before de-energizing to save battery power, dumbass)
• Pull 15a breaker from 3rd slot, replace with 10a. (This is required by NFTA/NEC, you MUST balance both legs.)
• Pull 15a breaker from rack slot, replace with 20a breaker.
• Replace 15a outlet with 20a outlet. (I want to install a safety/tamper-resist outlet)
• Re-energize circuit, and verify circuit validity w/oulet tester.
• De-energize circuit
• Plug UPS units back in.
• Re-energize circuits, verify UPS units are back on line-power.
• Go down 3 shots of alcohol and celebrate. 🎉
