The Lenovo RackSwitch G8052 is a 1U top-of-rack data center switch delivering 176 Gbps non-blocking throughput with 48 auto-sensing 10/100/1000 Mb Ethernet ports and four 10 Gigabit SFP+ uplink ports. It achieves 1.8 microseconds switching latency and 132 Million packets per second forwarding rate, supporting massive compute and virtualization workloads. The switch features redundant hot-swap power supplies (450W each) and fan assemblies with N+1 cooling redundancy, consuming only 130W typical power. Layer 2/3 capabilities include VLAN support, link aggregation, spanning tree protocol, and IPv4/IPv6 routing. Management options include CLI, SNMP v1/v3, and optional Lenovo XClarity integration. The G8052 supports jumbo frames up to 12,288 bytes and maintains 32,000 MAC address learning capacity, making it suitable for enterprise data centers requiring high-performance, reliable switching infrastructure.

New, certified-refreshed and OEM stock with guaranteed compatibility, backed by warranty on every part.
Typical power consumption of only 130W with variable-speed redundant fans and front-to-rear or rear-to-front airflow options reduces operational costs while maintaining N+1 redundancy for power supplies and cooling.
Enterprise Network Consolidation
Supports up to 4,094 VLANs (2,048 active) with 802.1Q tagging, RBAC, LDAP/RADIUS authentication, and port-based network access control (802.1x) for secure multi-tenant or departmental network segmentation.
Frequently asked questions
What is the maximum throughput and latency of the RackSwitch G8052?
The G8052 delivers 176 Gbps full-duplex non-blocking throughput with 132 Million packets per second (Mpps) forwarding rate and 1.8 microseconds switching latency. This ultra-low latency ensures minimal delay for time-sensitive applications, while the non-blocking architecture guarantees wire-speed performance across all 52 ports simultaneously.
How many ports does the G8052 have and what speeds are supported?
The switch features 48 auto-sensing 10/100/1000 Mb Ethernet ports with RJ-45 connectors and four 10 Gigabit Ethernet SFP+ ports. The SFP+ ports support both 10GbE SFP+ transceivers and 1GbE SFP transceivers, providing flexibility for mixed-speed deployments. All ports are hot-swappable.
What redundancy features are included in the G8052?
The switch includes dual load-sharing 450W AC hot-swap redundant power supplies and three hot-swap fan assemblies with N+1 cooling redundancy (optional fourth fan for 2+2 redundancy). All power supplies, fans, and SFP/SFP+ transceivers are hot-swappable, enabling maintenance without downtime.
What is the power consumption and cooling design of the G8052?
Typical power consumption is only 130W, significantly lower than competitive offerings. The switch features variable-speed fans that automatically reduce power usage and supports front-to-rear or rear-to-front airflow to match server configurations and optimize data center thermal management.
What Layer 2 and Layer 3 features does the G8052 support?
The G8052 supports Layer 2 switching with VLAN tagging (up to 4,094 VLANs, 2,048 active), spanning tree protocol (STP), link aggregation (LAGs), and virtual LAGs (vLAGs). Layer 3 features include IPv4/IPv6 routing, VRRP, and policy-based routing (PBR). It also supports OpenFlow and Edge Virtual Bridging (EVB).
What management and security options are available?
Management interfaces include industry-standard CLI (isCLI), SNMP v1/v3, and Netconf (XML). Optional Lenovo XClarity provides discovery, inventory, monitoring, and event management. Security features include SSH, SCP, sFTP, RBAC, LDAP/LDAPS, RADIUS, TACACS+ authentication, ACLs, and port-based network access control (802.1x).
What is the physical form factor and weight of the G8052?
The G8052 is a 1U rack-mount switch with dimensions of 440 mm (17.3 in.) width, 445 mm (17.5 in.) depth, and 44 mm (1.7 in.) height. It weighs 5.5 kg (12.0 lb), making it compact and suitable for high-density rack deployments in data centers.
