Best for
Enterprise Campus Networks
Deploy as core or distribution layer switch in medium-sized enterprise networks. The 48 Gigabit ports support high-density server and workstation connectivity, while Layer 3 routing capabilities enable inter-VLAN communication and advanced network segmentation with up to 4,093 VLANs.
Data Center Aggregation
Use as aggregation switch in data center environments. Optional 10 Gigabit uplink modules provide high-speed connectivity to core infrastructure, while 184 Gb/s switch fabric and 131 Mpps forwarding rate handle intensive east-west traffic patterns.
Distributed Campus Connectivity
Connect multiple IDFs and MDFs across campus locations. Four SFP combo ports support fiber optic runs up to 2 km (1000BASE-LX), and resilient stacking up to 12 systems creates redundant, high-capacity backbone infrastructure.
High-Performance Cluster Computing
Support HPCC environments with iSCSI optimization and advanced QoS features. The switch prioritizes time-sensitive cluster traffic and provides broadcast storm control for stable, predictable performance in compute-intensive deployments.
VoIP and Unified Communications
Deploy PowerConnect 6248P variant with PoE support for VoIP handsets and video conferencing endpoints. Up to 15.4 watts per port (with optional external power supply) powers network devices across all 48 ports.

What is the maximum throughput and forwarding capacity of the PowerConnect 6248?
The PowerConnect 6248 delivers 184 Gb/s switch fabric capacity with a forwarding rate of 131 Mpps (million packets per second). This non-blocking architecture supports wire-speed performance across all 48 Gigabit ports simultaneously, ensuring consistent throughput even during peak traffic periods without congestion-related latency.
Can the PowerConnect 6248 be stacked with other switches?
Yes, the PowerConnect 6248 supports resilient stacking up to 12 systems using optional YY741 stacking modules. Stacked systems create nearly 2 Terabits of aggregate capacity with automatic failover and simplified management through a single management interface, enabling highly available, scalable infrastructure.
What uplink options are available for backbone connectivity?
The switch includes four SFP combo ports supporting fiber connectivity (1000BASE-SX up to 500m, 1000BASE-LX up to 2 km). Optional 10 Gigabit Ethernet uplink modules are available in SFP+, XFP, CX4, or 10GBase-T copper formats, enabling flexible backbone and long-haul connectivity options.
Does the PowerConnect 6248 support Power over Ethernet (PoE)?
The standard PowerConnect 6248 does not include PoE. However, the PowerConnect 6248P variant provides up to 15.4 watts per port on all 48 ports (with optional external power supply), supporting VoIP handsets, wireless access points, video conferencing endpoints, and other PoE-dependent network devices.
What Layer 3 routing protocols are supported?
The PowerConnect 6248 supports RIPv1/v2, OSPFv1/v2/v3, CIDR, IGMP v2, DVMRP, and VRRP. It also includes static routing, ARP, ICMP, and comprehensive IP multicast support (PIM-DM, PIM-SM), enabling sophisticated network segmentation and traffic engineering without separate routing appliances.
How many VLANs can the switch support?
The PowerConnect 6248 supports up to 4,093 VLANs with double VLAN tagging (QinQ) and dynamic VLAN support via GVRP. The MAC address table accommodates 8,000 entries, enabling efficient VLAN-based network segmentation and traffic isolation across large enterprise deployments.
What management interfaces are available?
The switch provides web-based Graphical User Interface (GUI), Command Line Interface (CLI), and SNMP capabilities for comprehensive management. Security features include IEEE 802.1x-based edge authentication, switch access password protection, and user-definable settings for Web, SSH, Telnet, and SSL management access.
