Description

The Arista 7280R3 40-port 25G switch is a 1RU fixed data centre switch router built for leaf, spine and universal leaf roles, as well as internet peering, inter-DC interconnect and timing-sensitive carrier edge deployments. This 7280SR3E-40YC6-M model adds Synchronous Ethernet and expanded system memory over the base 7280R3 variant.

It provides 40 SFP ports running at 1/10/25G and 6 QSFP100 ports for 100G uplinks, with 800 Gbps of wire-speed throughput (1600 Gbps full duplex) and 600 Mpps forwarding. Latency starts from 3.8 us, backed by a 2 GB deep packet buffer and 32 GB of system memory. The front-to-rear airflow design is paired with two hot-swap AC power supplies in a 1+1 arrangement, and typical power draw is 130 W with a 214 W maximum.

The QSFP100 ports support 100G, 50G and 40G operation, plus 4x25G and 4x10G breakouts depending on the transceiver or cable used. It runs Arista EOS 4.28.1 or later and is managed with CloudVision. Power supplies use the PWR-511 family and fan trays use FAN-7011M.

FAQs

Q: What does the SyncE and expandable memory variant add?
A: This 7280SR3E model adds Synchronous Ethernet precision timing and 32 GB of system memory compared with the base 7280R3 variant, making it suited to timing-sensitive carrier and metro deployments.

Q: Which software does it run and is a licence required?
A: It runs Arista EOS, listed under EOS Feature Licenses Group 2, with a minimum release of EOS 4.28.1.

Q: What power supplies and fans does it use?
A: It uses PWR-511 AC or DC power supplies and FAN-7011M fan trays. This front-to-rear airflow model operates with two AC supplies in a 1+1 redundant arrangement.

Q: What speeds do the 100G ports support?
A: The six QSFP100 ports support 100G, 50G and 40G (QSFP+) operation, plus 4x25G and 4x10G breakouts, depending on the transceiver or cable used.

Q: What is the airflow direction of this SKU?
A: The -F suffix denotes front-to-rear airflow. Rear-to-front airflow is a separate -R variant using different power supplies.
