Buyer notes on how to write a cabinet brief. They are checklists, not a catalog and not a factory endorsement. LinkScope Sourcing 45 remains an independent sourcing partner when it publishes a note.
CABINET NOTE
A cost controller's 7-step checklist for sourcing custom server rack cabinets and enclosures — how to spec U-heights, compare 4U server rack price quotes on a real BOM, vet a custom AC server rack, and build a 5-year TCO sheet before you sign.
CABINET NOTE
A quality manager's account of a rejected rack batch, the usable-depth vs. external-depth gap, what really drives 4U server rack price spread, and when a custom AC server rack stops making sense.
Use a note to prepare rack units, external width, usable depth, door style, quantity, destination, and timing. Then move to the inquiry rows or the requirement form. A note does not reserve a cabinet and does not set a price. If the open question is a 4U skin versus a 4U occupant, the price-path page is the tighter split. If the open question is a cooler, the spec handoff lists voltage and condensate.
Dates on a note are publication dates for the checklist. They are not factory lead times. Any millimeter figure inside a note is a prompt for the drawing of the model a supplier names. It is not a rating assigned by this desk. Optional budget language in a note still needs a currency and a per-cabinet or whole-order basis when you later use the form.
A useful note stays narrower than a catalog. It tells you which cell to write, then stops. For a floor cabinet, the cells are rail count, external width in millimeters, usable depth, door perforation, static load with its unit, and whether casters ship installed. For a short wall box, add the fastener type and the swing of the door. Mixing those two jobs in one paragraph is how a later quote compares unlike objects.
Square-hole rails and threaded rails should be named before a chassis is declared compatible. A 19 in opening is the panel width, not the crate width. If the receiving door is 2100 mm, ask the supplier for packed height rather than assuming the rail height is the crate. Pallet, crate, and lift-gate charges belong on the commercial side of the sale brief, not inside a geometry sentence.
Cooling language in a note is a prompt, not a thermal model. Perforated doors and a side-mounted cooler are different plans. If the brief needs voltage and a condensate path, leave the note and use the spec handoff. This list will not assign an ingress protection code, a load-test certificate, or a shipping week.
