CABINET BRIEF · NOT A STOCK LIST

network rack manufacturers: prepare a comparable RFQ

LinkScope Sourcing 44 is an independent sourcing partner for buyers who need network rack manufacturers to answer one written cabinet brief. Record rack units, usable rail depth, static load, airflow, quantity, and the US destination before any factory price is ranked. This desk does not run a cabinet plant and does not hold floor bays.

  • Opening: 9U, 12U, 42U, 45U, or a custom rack unit count. One rack unit is 1.75 in (44.45 mm).
  • Envelope: external width 600 mm or 800 mm, and depth of 600, 800, 1000, or 1200 mm, kept separate from usable rail depth.
  • Mounting: 19 in (482.6 mm) EIA panel, or a 23 in relay frame, with square cage-nut holes or tapped 12-24 / M6 called out.

Evidence rows the first factory reply must fill

A brochure photo of a black bay is not a specification. Ask each respondent to tie the next rows to one model and one drawing date, for example 2024-11-06, so a later revision cannot slide into the comparison.

CheckWhat to writeWhat this desk will not infer
Rack units A 9U opening is 15.75 in of vertical mounting. State whether the figure is the rail opening or the external height. External height is not the same number as the rack unit count.
Load rating Static kilograms or pounds on the drawing, plus the lower figure that applies when the bay rolls on casters. An 800 kg static note is not an 800 kg rolling rating.
Cooling or airflow Front-to-back path, perforated door area, and whether the installed gear breathes from the side. A Power over Ethernet switch budget is a switch line, not a cabinet attribute.
Installation environment Indoor row, carrier cage, or outdoor box. If outdoor, ask the supplier for the ingress protection code on that model. This desk does not assign an IP code.
Power accessories Input voltage, output capacity, outlet or branch count, runtime, efficiency, and monitoring sit on a PDU or UPS line. An empty cabinet price does not include runtime.

Background: a regional integrator had three 42U replies for one IDF. Process: the desk split static load, caster load, and a monitored PDU onto separate lines and asked for the drawing date beside the hole pattern. Result: two replies that looked cheaper were missing shelves and a vertical manager, so the buyer compared the remaining pair on one scope. The example is a procurement situation, not a published customer result.

Where the cabinet sits in the build

Closet

Wall cabinets need stud spacing, door swing, and the deepest device plus bend room. A 100 mm planning gap behind a patch field is a buyer allowance, not a factory claim.

Row

Floor bays need bonding bars, vertical managers, and a stated tip path through the doorway. Crate size is a freight line.

Cage

Carrier cages still split 19 in panels from 23 in relay frames. An adapter plate is its own line item.

Dock

Who unloads, whether the bay ships assembled, and the destination zip code change the delivered total. Ex-works steel is not a landed cost.

Read the inquiry lines or the procurement brief before you send the RFQ. Insertion loss of a patch cord stays on the cord line. The cabinet quote does not absorb it.

Questions buyers ask before the first outreach

No. Width, usable depth, door style, hole pattern, and the accessory list still have to match. A 42U label only fixes the vertical opening count.

The named supplier, against the drawing revision in your brief. EIA-310 is the question source for the 1.75 in rack unit. This desk does not measure the frame.

No. Fans, PDUs, and monitored strips need their own evidence. A passive steel frame is usually outside equipment-authorization scope. Ask for the document that names the exact model.

Currency, and whether the figure is per rack or for the whole order. High-end, mid-range, budget, or undecided is a buyer preference, not a rating this desk has verified.

Send the cabinet facts to the factory desk

The form collects the requirement in the existing procurement field. Drawings can follow after a coordinator replies. There is no file upload on this page, and a submitted brief is not a quotation.

Limits: load is unread until a drawing states it; airflow is unread until the door and the installed gear are named; freight stays out of the steel price until the destination is named.
