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 are the 50 ports of the Zyxel GS1920-48V2 laid out?
44 Gigabit RJ-45 ports, 4 RJ-45/SFP combo ports and 2 Gigabit SFP slots. The combo ports can be used with either copper or fibre; the two dedicated SFP slots are for long-distance links between buildings or to an aggregation switch.
Does this 48-port switch supply PoE?
No, none of its ports delivers power. It is a switch designed for connecting workstations and servers. To power cameras or Wi-Fi access points, you need the PoE version from the same range, or injectors on the links concerned.
Do you need to know the command line to manage it?
No: everything is done through a web interface. VLANs, quality of service, IGMP snooping, LACP link aggregation and access control lists are all available from a browser, with no syntax to learn.
Can the GS1920-48V2 be managed from the cloud?
Yes, through Zyxel's Nebula platform, with no additional licence. Switching from standalone management to centralised management takes just a few clicks, so you do not have to replace the hardware as your network grows.
What performance does this switch deliver?
100 Gbps of switching capacity and 74 Mpps, with a 16,000-entry MAC address table. It supports IPv6 and the STP, RSTP and MSTP spanning tree protocols, and applies Energy Efficient Ethernet to idle ports.
Is this 48-port switch noisy?
It has a variable-speed fan that only speeds up when the temperature inside the housing requires it. On a 50-port rack-mounted switch, this is the usual compromise between cooling and quiet operation.
How much rack space does the GS1920-48V2 take up?
441 × 200 × 44.5 mm, i.e. 1U high and 20 cm deep, for 19-inch rack mounting. This moderate depth means it fits in a wall-mounted rack, provided air can flow out at the back.
Is the switch new and covered by a warranty?
Yes, new equipment, with the invoice serving as the warranty document. This is the Zyxel GS1920-48V2, part number GS1920-48V2-EU0101F.
