Description

The 7504N is a 7RU modular chassis for the Arista 7500R and 7500R2 Series. It suits large-scale Layer 2 and Layer 3 cloud designs, spine and leaf data centre fabrics, VXLAN overlay networks, internet peering and secure data centre interconnect, in both virtualised and traditional enterprise data centres.

This is the empty chassis, with 4 line card slots, 2 supervisor slots, 6 fabric module slots and 4 power supply slots. When populated it delivers up to 38 Tbps and 17.3 Bpps, with up to 144 x 100GbE, 144 x 40GbE, 288 x 50GbE or 576 x 25GbE/10GbE ports using 36-port 100G line cards. Redundancy covers the power grid, supervisors, fabric modules and fans, and all components are hot-swappable. Maximum chassis power consumption is 5,640 W, with AC or DC power supplies ordered separately.

It works with the DCS-7500-SUP2 supervisor, DCS-7504R-FM fabric modules (six required) and the 7500R, R2, R2A and R2AK line cards, with 3000W AC and DC power supplies available. The chassis is sold without a licence, and optional EOS software licences are available per slot count.
