What port configuration does the Black Box LPB5052A provide?

The LPB5052A offers 48 x 10/100/1000BASE-T RJ45 ports with PoE+ (IEEE 802.3at/af, up to 30W/port) and 4 x 10 Gigabit SFP+ slots supporting 1/10Gbps fiber/copper transceivers. This hybrid design handles high-density access traffic while providing 10G uplinks for non-blocking backbone connectivity in enterprise LANs.

What management features are available on this switch?

Full L2+ management via SNMPv1/2c/3, integral Web server GUI, CLI console, RMON groups 1/2/3/9, port mirroring, LLDP, sFlow, dual image support, SSHv2, RADIUS, Syslog, and cable diagnostics. Enables comprehensive monitoring, configuration, and troubleshooting for IT teams managing distributed networks.

Does the LPB5052A support VLANs and QoS?

Yes, supports up to 4096 VLANs (port-based, 802.1Q tag-based, MAC-based) for traffic segmentation and 802.1p/DSCP QoS with 8 queues per port for prioritizing VoIP, video, and critical data. Guest VLAN allows secure Internet access for visitors without network exposure.

Is this switch energy efficient and secure?

IEEE 802.3az EEE reduces power during low activity (up to 50% savings), plus cable length detection optimizes signal for shorter runs. Security includes 802.1x port authentication, SNMPv3 encryption, SSH/SSL, and MAC address filtering for enterprise-class protection.

What are ideal deployment scenarios for LPB5052A?

Perfect for enterprise access switching, campus LAN aggregation, PoE edge for cameras/APs/phones, and SMB offices. TAA compliance suits government use; 1U rack form factor fits standard 19-inch cabinets with robust Layer 2+ features for scalable growth.

What is the MAC address table size and Jumbo Frame support?

32K MAC address table size supports dense environments; Jumbo Frames up to 9KB enable efficient large data transfers like backups or video streaming without fragmentation, improving throughput in data center edge or multimedia applications.
