Lenovo G8264 Rackmount Layer 3 Switch

The Lenovo G8264 is a rackmount Layer 3 network switch built for high-density aggregation. It provides forty-eight 10 Gigabit Ethernet expansion slots and four 40 Gigabit Ethernet expansion slots for uplink flexibility. SFP uplink ports are included to support a variety of transceiver types. This switch targets data-centre and enterprise core deployments that demand non-blocking throughput.

Suited for 10G and 40G spine-leaf fabrics

Network architects building spine-leaf topologies with 10G server links and 40G uplinks will match the port layout directly. The Layer 3 feature set enables routing between VLANs and subnets without an external router. Teams needing Power over Ethernet, 1G copper density, or 100G uplink capability should evaluate other platforms that provide those specific interfaces.

Forty-eight 10G plus four 40G expansion slots

The decisive specification is the combination of forty-eight 10 Gigabit Ethernet expansion slots and four 40 Gigabit Ethernet expansion slots in a single rackmount chassis. This fixed port count defines the maximum server and uplink density available from the unit. Confirm that your transceiver and cabling plan aligns with the supported 10GBase and 40GBase standards listed for these slots.

Questions about this item

How do I install the 48 10GbE and 4 40GbE expansion-slot ports in a rack, and what step is often missed?

Mount the rackmount chassis, then insert each SFP+ or QSFP+ transceiver into the correct expansion slot before cabling; the step most often missed is matching the transceiver speed to the port label.

Which components will need replacement over the life of the Lenovo 7159G64 switch?

Hot-swap power supplies and fan modules are the field-replaceable units; transceivers in the 48 10GbE and 4 40GbE slots are swapped when link requirements change.

What throughput limit appears first when all 48 10GbE and 4 40GbE ports run sustained traffic?

The aggregate backplane capacity of the G8264 chassis becomes the bottleneck before any individual 10GbE or 40GbE port saturates.
