Description

The Arista 7800R4 4-slot chassis is an empty 10RU modular platform for the 7800R Series of data centre switch routers. It is built for cloud, data centre and service provider networks, including large-scale layer 2/3 spine, EVPN-VXLAN overlays, data centre interconnect, Internet peering, MPLS and Segment Routing cores, and AI/ML and HPC spine networks.

The chassis provides 4 line card slots, 2 supervisor slots, 6 fabric module slots (5 fabric modules plus 1 fabric cooling module) and 8 power supply slots for a 24 kW maximum power budget. Density reaches up to 144 x 800G, 288 x 400G or 1152 x 100G ports depending on line card breakout, with maximum throughput of 115 Tbps (230 Tbps FDX). The chassis supports an AC or DC power option. It runs Arista EOS, and no licence is included with the bare chassis.

It works with DCS-7804R4-FM fabric modules in slots 1-5, the DCS-7804-FCM fabric cooling module in slot 6, and DCS-7800-SUP1A, DCS-7800-SUP1S, DCS-7808-SUP2 and DCS-7808-SUP2-N supervisors. Compatible 3000 W power supplies include PWR-D1-3041-AC, PWR-D2-3041-DC and PWR-D4-3041-AC.

FAQs

Q: Does the DCS-7804-CH include a licence?
A: No. The chassis has no licence included. It runs Arista EOS, and feature licences such as FLX come with bundles like DCS-7804R4-BND-FLX or are purchased separately. CloudVision is a separate product.

Q: Which power supplies does this chassis use?
A: The chassis has 8 power supply slots for a 24 kW maximum power budget. Compatible 3000 W units are PWR-D1-3041-AC, PWR-D2-3041-DC and PWR-D4-3041-AC, covering AC and DC feeds.

Q: Which supervisors and fabric modules fit this chassis?
A: Supervisors are DCS-7800-SUP1A, DCS-7800-SUP1S, DCS-7808-SUP2 and DCS-7808-SUP2-N. Fabric slots 1-5 take DCS-7804R4-FM modules and slot 6 takes the DCS-7804-FCM fabric cooling module.

Q: Which line cards work in this chassis?
A: It supports 7800R4 line cards, including the 7800R4-36PE and 7800R4K-36PE with 36 x OSFP800 ports, among other 7800R4 line cards.

Q: How does the DCS-7804-CH differ from the bundled versions?
A: The DCS-7804-CH is the empty 4-slot, 10RU chassis only. The DCS-7804R4-BND family bundles this chassis with additional components such as fabric modules and power supplies.
