1. High density PoE+and 10G uplink configuration: suitable for medium to large access scenarios
The Extreme Networks X460-G2-48P-10, as a mid to high end access layer/aggregation layer model, features a port design centered around "high-density power supply+high-speed uplink" to meet the needs of large-scale terminal access
PoE+access ports: equipped with 48 10/100/1000 BASE-T adaptive electrical ports, all supporting IEEE 802.3af/at PoE+standards, with a maximum output power of 30W per port, capable of supplying power to 48 terminals such as IP phones, dual band wireless APs, high-definition dome cameras, etc. without the need for additional power modules, suitable for high-density terminal scenarios such as enterprise headquarters floors and large parks.
10G uplink expansion port: includes 4 SFP+10G optical ports (non multiplexed design), supports 10GBASE-SR/LR and other optical modules, can directly connect to core switches (such as Extreme X670 series) or servers, achieve 10Gbps high-speed uplink, solve the bandwidth bottleneck of traditional gigabit uplink, and meet bandwidth intensive business needs such as video conferences and big data transmission.
Flexible expansion interface: Reserve 2 modular slots (such as XGM2 module slots), which can expand more 10G optical ports or 10G electrical ports, adapt to the port expansion needs after business growth, and avoid duplicate equipment procurement.
2. High power PoE and high-performance forwarding: balancing power supply and transmission efficiency
Extreme Networks X460-G2-48P-10 balances high-density PoE power supply and data forwarding performance, supporting medium to large network loads:
PoE power guarantee: The overall PoE power budget is as high as 740W, which can supply power to 48 PoE+devices at full load (48 × 30W=1440W, actually supporting 740W, meeting the mixed access of high-power terminals in most scenarios). Even if 48 dual band APs are connected (each about 15-25W), there is no need to worry about insufficient power or additional PoE expansion modules.
Core performance parameters: exchange capacity up to 256Gbps, forwarding rate 192Mpps, 64 byte packet latency less than 3 μ s, compatible with 9KB jumbo frames; 48 gigabit electrical ports and 4 10G optical ports both support line speed forwarding, and the total bandwidth of the ports is twice the sum (48 × 2Gbps+4 × 20Gbps=176Gbps), which is much lower than the switching capacity, ensuring non blocking transmission and avoiding network lag caused by multi terminal concurrency.
