Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Ports : the number and type of ports (RJ45, SFP, PoE) differ between models of a single series, which nevertheless shares one photo.
  • Antennas : their number, gain and whether they can be removed depend on the reference.
  • Modules and cables : SFP modules, transceivers, DAC cables, PoE injectors and rack-mounting kits are not included unless stated.
  • Power : some equipment is powered over PoE and shipped without a power adapter.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

Frequently asked questions about this product

How many PoE+ ports does the ZyXEL GS1920-48HPV2 have?
44 ports at 100/1000 Mbps, all PoE+ 802.3at, up to 30 W per port. On top of these come 4 SFP or copper combo ports and 2 dedicated SFP slots, reserved for uplinks.
Is the 375 W PoE budget enough for the 44 ports?
It is a budget to be shared out, not 30 W guaranteed on every port. 375 W covers 44 ordinary IP phones or fixed cameras; however, around twenty motorised cameras at full power would already exhaust the budget.
What is the difference between the combo ports and the dedicated SFP slots?
The 4 combo ports can be used with fibre or copper, as you choose, but never both at once on the same slot. The 2 dedicated SFP slots, on the other hand, only accept fibre: they are in addition to the 44 access ports and do not take up any of them.
What level of management does this switch offer?
Layer 2 web management, with SNMP monitoring and IPv6 compatibility. VLANs, quality of service and PoE port monitoring are configured from a browser, without a command line.
How much power should you allow for in the rack?
Up to 474.3 W, once the 375 W of PoE is being delivered. On a 48-socket switch, this is the figure to use for the UPS as well as for the rack ventilation.
How much rack space does this switch take up?
441 × 270 mm and 4.1 kg, in 1U. At 27 cm deep, it needs a standard 19-inch rack — a shallow wall-mount cabinet will not do.
Is the switch new and covered by a warranty?
Yes, new equipment, with the invoice serving as the warranty document. This is the ZyXEL GS1920-48HPV2, reference GS192048HPV2-EU0101F.
