poe ethernet switch 16 port
These cards help a buyer start a brief for a poe ethernet switch 16 port requirement and for neighboring port counts in the same family. A card is an inquiry label. It does not mean a chassis is on a shelf, and it does not name an authorized channel.

What a 16-port PoE reply still has to state
A poe ethernet switch 16 port quotation is incomplete when it lists sixteen RJ45 openings and stops. Ask which PoE class each port can source, and whether that class is available on all ports at once. IEEE 802.3af is often discussed as 15.4 W at the PSE for a powered device up to 12.95 W after cable loss. IEEE 802.3at is often discussed as 30 W at the PSE. IEEE 802.3bt raises the class further, into the 60 W and 90 W discussions. Those class names are questions. The watt number you compare is the one printed for the named model and its power supply.
Total PoE budget is the figure that stops a buyer from multiplying port count by per-port class. A 16-port unit with a 240 W budget cannot feed sixteen 30 W loads together. A 370 W budget still needs the datasheet sentence that says how the watts are shared, and whether a fan or a second supply is required above a stated load. Copy that sentence. Do not infer it from the faceplate.
Port speed sits beside the power question. Confirm 10/100/1000 Mb/s on the copper ports, and whether the uplink is a shared SFP cage, a fixed fiber port, or another copper port that you should not count twice. If cameras need a VLAN and the access points need a separate management address, say whether the unit must be managed. An unmanaged 16-port PoE unit can be the right line for a flat camera segment. It is the wrong line when the brief asks for SNMP traps or 802.1X.
Rack format, depth, and acoustic noise matter in a closet that is not a data hall. Ask for millimeters of depth, the operating temperature range, and whether the supply is internal. External injectors change both the price and the failure points. Keep them as separate lines if the supplier offers them as accessories.
When two replies use different currencies, normalize after you know whether the figure is per switch or for the whole order, and after optics, licenses, and freight are either included or listed. The SFP quote page covers two-port fiber edge units that sometimes sit next to this PoE brief, and the RFQ form is where the watt budget and destination are sent.
