✔ Pros: Dense 64 x 400GbE QSFP56-DD in a 2U fixed chassis; Up to 25.6 Tbps unidirectional switching capacity and 10.53 Bpps forwarding for spine and super-spine roles; Port channelization allows 100G/200G breakout from 400G ports; 112 MB packet buffer and 9,216-byte jumbo frame support; Layer 2 and Layer 3 switching with EVPN-VXLAN fabric support on Junos OS Evolved; Redundant 1+1 hot-swappable power supplies and fan modules; AC and DC power and airflow variants for flexible data center deployment
✘ Cons: No PoE support, so it is unsuitable for access-layer powered devices; Virtual Chassis or stacking support is not confirmed in Juniper's specifications; Premium price of roughly $55,000 to $63,000 per unit based on the reseller listings found; Average power draw near 500 W and maximum near 1.4 kW require substantial power and cooling planning; Only 2 SFP+ ports limit legacy 1G/10G connectivity; AFO variants are rated for altitudes up to 6,000 ft and use different airflow than AFI variants, which complicates procurement; Price range is based on only two US reseller listings and may not reflect Juniper list pricing
Est. Price: $54,635 - $63,300
