48-Port Fast Ethernet Layer 3 Switch

The HP 1910-48 provides 48 Fast Ethernet ports and two combo Gigabit SFP uplinks for rack-mounted network infrastructure. It targets administrators who need basic Layer 3 routing between VLANs without the complexity or cost of full campus cores. The unit ships with power, serial, ground cables and a mounting kit for immediate 1U deployment. Managed features include SNMP, VLANs and static routing for segmented office traffic.

Practical limits of Fast Ethernet uplinks

Each of the 48 RJ-45 ports operates at 10/100 Mbps, so aggregate throughput is bounded by 100 Mbps per access link. The two SFP slots accept Gigabit transceivers for 1000 Mbps uplinks, yet they share bandwidth with the two fixed Gigabit copper ports, limiting simultaneous uplink capacity. No PoE support means separate injectors or midspans are required for phones, cameras or wireless access points. Redundant power supply is optional but not included in the box.

Upgrade from unmanaged Fast Ethernet stacks

This switch replaces unmanaged 10/100 hubs or basic web-smart switches that cannot route between VLANs or enforce ACLs. The jump is worth it when departments need inter-VLAN routing, QoS for voice or basic IPv4 static routes without licensing fees. It does not suit environments requiring 10 Gigabit uplinks, PoE+ budgets, stacking for single-pane management or deep Layer 3 feature sets such as dynamic routing protocols.

Questions about this item

Should I pick the 48-port model or a smaller switch for my rack?

The 1910-48 provides 48 Fast Ethernet ports plus two Gigabit SFP uplinks in a single 1U rack-mountable chassis, so it fits one rack unit while delivering high port density.

What does the 48-port Fast Ethernet spec mean for actual throughput?

Each of the 48 RJ-45 ports runs at 10/100 Mbps, while the two SFP uplink slots support 1000 Mbps Gigabit connections for faster aggregation to core switches.

Which SFP standard do the two uplink slots use and what speed do they cap at?

The two shared SFP expansion slots accept standard SFP transceivers and operate at Gigabit Ethernet speeds, providing 1000 Mbps uplink capacity per slot.
