Description

The 7280R3A is a 2RU fixed data centre switch router built for large-scale spine and leaf deployments, carrier edge and core roles, secure internet peering and data centre or WAN interconnects that need line-rate encryption. This 7280CR3AM variant is the M model, adding MACsec and TunnelSec encryption on all ports, with the FLX routing licence bundled, front-to-rear airflow and two AC power supplies.

It provides 48 x 100GbE QSFP100 ports and 6 x 400GbE QSFP-DD ports, with a maximum of 68 x 100G ports when breakout is used. Throughput is 7.2 Tbps (14.4 Tbps full duplex) at 2.7 Bpps, with an 8 GB packet buffer and latency from 3.8 us. Precision timing is supported through PTP and SyncE with OCXO and PPS/10M/ToD inputs. An eight-core x86 CPU with 64 GB of RAM and a 120 GB SSD runs Arista EOS.

Power comes from two hot-swap AC supplies in a 1+1 arrangement, cooled by four N+1 fans. Typical draw is 388 W and maximum draw is 979 W. Optional Group 4 EOS licences extend the feature set, and the switch is managed through CloudVision.
