Quotation scope
Industrial Ethernet Switch 16-Port
A 16-port request fails comparison when one factory prices copper ports and another quietly adds optics, licenses, or a redundant power module. Write the bill of materials before anyone sends a number.
Interface: sixteen copper jacks, or a mix with SFP cages.
Power: single or dual input, and any Power over Ethernet watt budget.
Evidence: current datasheet row for the exact model.
Lines each factory should price on the same sheet
LinkScope Sourcing 13 is an independent sourcing partner. The desk does not own the switch line and does not treat a catalog photo as stock. Use the rows below as the comparison frame for an industrial ethernet switch 16-port quote.
| Line | Buyer entry | Factory answer |
|---|---|---|
| Port map | Count 10/100/1000 Mb/s copper separately from 1 Gb/s or 10 Gb/s uplinks. | Exact model, jack type, and any cage that ships empty. |
| Switching capacity | Sixteen 1 Gb/s ports, full duplex, sum to 32 Gbps if every port is in the non-blocking claim. | State the test topology and whether uplinks are inside that 32 Gbps figure. |
| Forwarding rate | About 1.488 Mpps per 1 Gb/s at 64-byte frames, so 16 such ports are near 23.8 Mpps. | Publish the frame size. A 1518-byte result is not the same cell. |
| Power over Ethernet | 802.3at is 30 W at the PSE port before cable loss. 802.3bt Type 4 is discussed near 90 W and needs a supply that can hold the sum. | Total PoE budget, per-port cap, and whether the power supply is included. |
| Exclusions | SFP modules, licenses, DIN kits, and commissioning start outside the unit price. | Mark each item included, optional, or refused. |
A managed industrial ethernet switch on this port count may add a software license for VLANs, RSTP, or a ring protocol. Ask which license is required for the features in the brief, and which features work with the license omitted. Impedance on the copper ports remains a 100 ohm question when the horizontal run is long. Insertion loss on a short patch is a different question from a 90 m channel.
Optical uplinks need their own row. Wavelength, optical budget, and receiver sensitivity belong to the SFP, not to the switch chassis nameplate. A 1310 nm 10 km claim has to name the exact optic. Single-mode fiber supports longer reach when the plant and the optic match. Multimode fiber may suit a short data-room hop with a compatible pair. Neither choice is proved by the cage color.
Procurement scenario: a control room that grew past eight ports
Background: the buyer already has eight devices in one cabinet and expects scanners plus two uplinks within the year, with 48 VDC available and a request for PoE on six ports. Process: the note sets an industrial ethernet switch 16-port target, asks for a 32 Gbps switching capacity basis, a forwarding rate at 64-byte frames, a Power over Ethernet budget at 802.3at 30 W on those six ports, and a dual power input as a preferred line. Result: factories return one sheet with empty SFP cages called out and licenses listed as optional. The comparison does not invent a freight figure and it does not claim a tested ring.
Open the inquiry configurations if you still need a managed or 4-port card beside this scope.
Questions that keep a 16-port quote comparable
Should refurbished units sit on the same sheet as new units?
New equipment may offer a clearer license and warranty path. Refurbished equipment may cover a legacy chassis when condition, hours, and entitlement are written down. Ask for both when the brief says the condition is acceptable. Do not blend the two prices.
Does an OEM-coded optic belong in the switch price?
An OEM-coded module may align with a host vendor policy. A compatible module may widen the factory list when it is verified on the exact switch. Put the optic on its own line either way. A cage photograph is not an optical budget.
Which costs stay outside the unit price?
Freight, duties, spare power modules, configuration time, and a site witness are separate until the buyer adds them. Currency and the per-unit or whole-order basis belong in the optional budget note.

There is no file upload on this desk. Copy the port map, the 32 Gbps question, the PoE watt sum, the quantity, the US destination, and the requested timing into the box. Factories can then answer exclusions in writing.
