Copper face
Write 8 ports, the speed of each, and whether any port is a combo that disables its neighbor. Data rate is a per-port cell. A 2.5 Gbit/s multi-gig port is not a silent upgrade of a 1 Gbit/s row.
LINE BY LINE
8 port managed network switch
An 8 port managed network switch line on a bill of materials needs its own port map, power entry, and license row before two factory replies can be ranked. LinkScope Sourcing 14 keeps those rows from collapsing into one chassis price. The workflow is a comparison method, not a stock reservation.

Uplink cage
Name SFP or SFP+, wavelength, fiber mode, reach, and connector. An 850 nm multimode optic and a 1310 nm single-mode optic are alternate rows, not synonyms. Optical budget uses transmit power minus receiver sensitivity, then you subtract plant insertion loss.
Power entry
Record Power over Ethernet class and total watts. Eight ports at 802.3at, 30 W, can ask for about 240 W before overhead. If the real load is two phones at 802.3af, 15.4 W, do not copy the 240 W figure. Power input such as 100-240 VAC and the cord type stay on this card.
License and metal
Management method, routing or security features, and the software term are a fourth card. Stacking cables, rack ears for a 1 rack unit or a desktop shell, and spare optics do not hide inside the chassis cell.
How two replies are lined up
| BOM cell | Reply A must show | Reply B must show |
|---|---|---|
| Exact model | Manufacturer, model, revision | Same three fields, or a named deviation |
| Switching capacity | Gbit/s and frame size | The same frame size, or the cell stays open |
| Forwarding rate | Mpps at 64-byte frames | Mpps on the same test basis |
| Commercial basis | Currency, per switch or whole order, Incoterm, exclusions | The same basis before any rank |
OEM-coded optics may track a vendor support policy more closely. Compatible optics may broaden the factories you can ask, after the exact host and software release are named. Put the preference in the cell. Do not let a photo of a latch decide it. New condition and refurbished condition stay in a condition cell with warranty months. A lower refurbished rate is not a percentage off the new line. It is a different line.
Background for a second worked pass: a branch with 6 phones and 1 uplink, counted on a planning sheet dated 2026-10-27. Process: the buyer froze an 8 port managed network switch, fanless if the room is occupied, 802.3af on the phone ports, and one 1310 nm SFP with a 10 km reach question. Result: the reply that swapped in multimode 850 nm was parked as a deviation because the plant note said single-mode. No install is claimed. The result is a cleaner comparison sheet.
Open questions to close before you accept an alternate row
Which cells are still blank?
Port speed, PoE watts, wavelength, license term, and rack format. A blank cell is not a match. Ask the factory to fill it or to mark the row unknown. Environment, such as 0 C to 50 C, is blank until the datasheet states it.
What proves the alternate?
A current datasheet and, when you require it, a test sheet tied to that model. Connector mating cycles matter if staging reseats the optic. Calibration traceability applies to the meter behind an optical test sheet, not to the switch logo.
Where do standards stop?
The IEEE 802 overview checked on 2026-10-27 frames interoperability questions. It does not prove this pair works. FCC equipment rules, reviewed the same day as a question source, still need a model-level answer if authorization applies. This desk does not file that paperwork.
What leaves the comparison?
Freight, duties, spares, commissioning, and a target budget with currency. Quantity and destination change those numbers. Rank the metal after the extras are either included or listed as excluded on both replies.
