Description

The DCS-7516N-CH is the empty 29RU chassis of the Arista 7500R Series, a modular data centre switch router with 16 line card slots. It suits large-scale data centre spine and leaf designs, layer 2 and layer 3 cloud networks, VXLAN overlays, internet peering and secure data centre interconnect, all running Arista EOS.

The chassis provides 16 line card slots, 2 supervisor slots, 6 fabric module slots and 20 power supply slots, with an AC or DC power option. System throughput reaches 150 Tbps and 69 Bpps, with up to 9.6 Tbps per slot. Fully populated it scales to as many as 576 x 100GbE, 576 x 40GbE, 1,152 x 50GbE or 2,304 x 25GbE and 10GbE ports. Maximum power consumption is 22,000 W, and the chassis measures 128.9 x 48.3 x 94.1 cm with front-to-rear airflow.

It works with DCS-7516R-FM fabric modules, a 7516 supervisor such as the DCS-7516-SUP2, 7500R, 7500R2 and 7500R3 series line cards, and 3kW power supplies including PWR-3KT-AC-RED, PWR-3KT-HV-RED and PWR-3K-DC-RED. The chassis itself needs no licence, while routing and feature licences such as FLX are ordered separately.

FAQs

Q: Does the DCS-7516N-CH need a licence?
A: The chassis itself needs no licence. Routing and feature licences, such as the FLX licence for the 16-slot chassis, are ordered separately and are needed for advanced routing, EVPN/VXLAN and MPLS scale.

Q: Which power supplies does this chassis use?
A: It has 20 power supply slots and supports 3000W supplies: PWR-3KT-AC-RED (200-240V AC), PWR-3KT-HV-RED (208-240V AC) and PWR-3K-DC-RED (-48 to -60V DC). Maximum chassis power consumption is 22,000 W.

Q: What modules does it work with?
A: It requires DCS-7516R-FM fabric modules in slots 1 to 6, a 7516 supervisor such as the DCS-7516-SUP2, 7500R, 7500R2 or 7500R3 series line cards, and 3kW power supplies. It supports 100G QSFP, 40G QSFP+, 25G and 10G optics per the 7500R optics matrix.

Q: How does it differ from the 7500R chassis with fewer slots?
A: This is the 16-slot, 29RU model with 20 power supply slots and an AC or DC option. It offers the highest port density in the range, up to 576 x 100GbE ports when fully populated.
