Arista CCS-722XPM Series PoE Switches

The Arista CCS-722XPM Series provides two stackable campus PoE switch models, the 722XPM-48ZY8 and the 722XPM-48Y4, differentiated by downlink speed and uplink configuration. The 722XPM-48ZY8 delivers 48 ports of 2.5G multi-gigabit copper PoE at 60W each, backed by eight 25G SFP uplinks and a 640 Gbps switching fabric, making it appropriate for floors deploying Wi-Fi 7 APs that benefit from 2.5G client-side attachment and drawing 60W via 802.3at. The 722XPM-48Y4 serves 1G access environments with 48× 1G RJ45 at 30W PoE, combined with four 25G and four 10G SFP uplinks, providing 376 Gbps of switching capacity and a 967W PoE budget, the highest available PoE budget in the 722XPM family. Both models support 802.1AE MACsec 256-bit on every downlink and uplink port.

Forwarding tables (64K MAC, 32K/16K IPv4/IPv6 hosts, 16K/6K IPv4/IPv6 routes, 64-way ECMP, 64 MST and 254 RPVST+ spanning-tree instances, and 4K IGMP groups) match the capacity of the 720XPM/XDM series and exceed the 710-series compact switches, placing the 722XPM in the same dense wiring-closet tier. DC PSU options (500W) alongside the standard 650W and 1050W AC supplies allow the 722XPM-48ZY8 to be deployed in facilities using a 48V DC UPS bus, widening the range of sites where the switch can be powered without a dedicated AC circuit. Arista EOS, CloudVision CMP, and gRPC/gNMI telemetry operate identically to all other 720-series campus models, keeping the 722XPM in the same management and provisioning pipeline as the broader campus access estate.
