A commercial managed network switch quotation is comparable after the port map is fixed. LinkScope Sourcing 14 is an independent sourcing partner. The desk asks factories to price the same copper count, uplink cages, Power over Ethernet budget, management method, and license scope, then lays those replies next to one another.
Write the host side before the number: access VLANs you expect to configure, whether the closet is 1 rack unit deep or a wall box, and the destination that sets freight. A bare chassis rate without those fields mixes different products. An IEEE 802 overview checked on 2026-10-27 can suggest the question set. It does not certify any proposed model.

Each row is a field the supplier answers. The desk does not treat a family catalog as proof that the offered model matches the row. Related notes sit on the procurement brief.
State copper ports and uplink cages separately. A 16 copper plus 2 SFP line is not the same cell as 16 ports when two of them are combo ports.
Mark 1 Gbit/s access, 2.5 Gbit/s multi-gig, or 10 Gbit/s uplinks. Ask which ports share a PHY so a speed label is not assumed across the faceplate.
Ask for switching capacity in Gbit/s and the frame size used. A non-blocking check often compares that figure with port count times line rate times 2. Record the supplier figure. Do not invent it.
Request forwarding rate in million packets per second at 64-byte frames. About 1.488 Mpps per 1 Gbit/s port is a comparison yardstick, not a result this desk measured.
Name IEEE 802.3af at 15.4 W, 802.3at at 30 W, or 802.3bt at 60 W or 90 W if that is the class you need, plus the total budget in watts. Per-port class and total budget are different cells.
Split chassis, optics, stacking cables, management licenses, freight, duties, and commissioning. A lower chassis rate that omits the license is a different purchase.
Use this line for the managed access ports that face phones, cameras, or workstations. Record port count, speed, and whether Power over Ethernet is required on every port or on a subset. Keep unmanaged desktop bricks off this line so the management method stays visible.
An SFP or SFP+ cage is a hole until the optic is named. Write wavelength, fiber mode, reach, and connector as their own row. A 1310 nm single-mode optic and an 850 nm multimode optic do not share a price cell. Optical budget and receiver sensitivity come from the optic datasheet, not from the switch family brochure.
CLI, web, SNMP, and a cloud controller are different support paths. Ask which features need a license after year one, and whether the MAC address table size and storm control are in the base image. A photograph of a console port does not establish the software scope.
Managed and unmanaged hardware answer different jobs. A managed switch supports monitoring, VLAN segmentation, and policy control when those features are specified. An unmanaged switch can reduce configuration work on a fixed island that will never be segmented. Put the choice in the brief so factories do not substitute one for the other.
Open the inquiry options or send the map from the RFQ form.
A cage labeled SFP does not answer fiber mode. Ask for wavelength, reach, connector, and the optical budget against the measured plant loss. Insertion loss of a dirty patch panel can erase a short-reach optic even when the switch port lights.
Thirty watts at one port under 802.3at can still fail if the chassis budget is 120 W and twelve cameras draw at once. Ask for the total watt figure, the per-port class, and the power input, such as 100-240 VAC.
Optics, licenses, rack ears, a 1 rack unit shelf, freight, duties, and the destination. Those items move the landed total even when the port count matches. Currency and per-switch or whole-order basis belong in the same packet.
The IEEE 802 overview is a question source checked on 2026-10-27. It does not prove interoperability for an untested pair. Ask the supplier which datasheet revision and which host platform the reply uses.
Send the port map, quantity, US or other destination, and the timing you need. The desk coordinates replies. It does not publish a standing price and it does not claim the factories have been audited by this site.
There is no file-upload control. Paste the line list into the requirement field, or say that a spreadsheet will follow the first reply.
