  • Layer 3 static routing with 32 IPv4 and 32 IPv6 entries
  • 16384 MAC address table scales with network growth

48-Port Managed Gigabit Switch

The HPE 1920-48G is a Layer 3 managed switch with 48 copper ports and four Gigabit SFP uplinks. It fits a 1U rack-mountable enclosure and also supports desktop placement. The switch delivers a switching capacity of 104 Gbps and a throughput of 77.4 Mpps. It is built for networks that need wired Gigabit connectivity with basic routing.

Suited for Managed LANs.

This switch suits administrators who need VLANs, static IPv4 and IPv6 routing, and SNMP or SSH management in a single rack unit. It supports Spanning Tree variants, IGMP snooping, port mirroring and Access Control Lists. Buyers who need more than four SFP uplinks, dynamic routing protocols, or a larger IPv4 routing table should look at other models.

32-Entry IPv4 Routing Table Limits Layer 3 Scale

The IPv4 routing table holds 32 entries, and the IPv6 table holds 32 entries. This capacity decides whether the switch can serve as a core Layer 3 device for a given network. Networks with more than 32 routed subnets will exceed the table and require a different platform.

Questions about this item

What maintenance or replacement will the 1920-48G need under continuous operation?

The switch has no user-serviceable parts; with a 99-year limited warranty it is designed to run without scheduled component replacement.

Which limit appears first on the 1920-48G during sustained heavy traffic?

The IPv4 and IPv6 routing tables each hold 32 entries, so the routing capacity fills long before the 16384-entry MAC table or 104 Gbps switching fabric.

How much noise, heat or power does the 1920-48G produce when running all day?

As a fanless 1U rack-mount unit it operates silently, and its throughput of 77.4 Mpps at 104 Gbps switching capacity indicates low thermal output for continuous duty.
