Frequently asked questions about this product
Can a 48-port switch run without a fan?
Yes, this one can: the HP 1820-48G has a fanless design, so it is completely silent, and it draws only 39 W. That is what lets you install it in a cabinet close to the offices rather than in a wiring closet.
What features does this managed switch offer?
VLANs, link aggregation, rapid spanning tree and quality of service with DSCP and 802.1p prioritisation, all from a web browser. IGMP snooping also optimises the delivery of video and multicast streams.
What latency does this switch claim?
Under 2.4 µs at Gigabit and under 7 µs at 100 Mbps, on 64-byte packets, with 104 Gbps of switching capacity and up to 77.3 Mpps. The MAC address table holds 16,000 entries.
Does this switch pass jumbo frames?
Yes, up to 9,220 bytes, which speeds up backups and large copies to a server — provided the network cards are set to the same frame size.
What uplinks does this model offer?
Four SFP slots at 100 or 1,000 Mbps, in addition to the 48 Gigabit copper ports. They take fibre modules to link another building or the core switch, beyond the 100-metre reach of copper.
How much rack space does this switch take up?
44.25 × 24.61 × 4.39 cm and 3.31 kg: 1U high and 25 cm deep, with the 19-inch mounting kit included. A shallow, silent 48-port chassis, which is rare.
Is the switch new, and where can I find its datasheet?
Yes, new equipment, with the invoice serving as the warranty document. The manufacturer's document details the HP 1820-48G, its web management features and its specifications: datasheet (PDF).
Total PoE+ budget of 384 W to power a large number of cameras, Wi-Fi access points and IP phones. 104 Gbps switching capacity, driven from the Omada SDN cloud.
Covers a whole floor of cameras, Wi-Fi access points and IP phones on a single device, without multiplying power units. 10G links and a capacity of 176 Gbps absorb the combined traffic. VLANs, security and administration of enterprise equipment.
Layer 2 Gigabit switch for SMEs, with PoE+ ports to power cameras and Wi-Fi access points, plus SFP fibre links. Silent rackable format, driven through UniFi Network.
Designed for enterprise and campus networks, with advanced security and automatic IP camera recognition. 10 Gbps uplinks for aggregation towards the network core.
