The DCS-7500R2AK-36CQ-LC is the large-route version of the 7500R2 36-port 100GbE card. The K models hold over 2 million IPv4 and IPv6 LPM routes, which gives headroom for full Internet tables plus internal and VPN routes on the same system.

The card also includes AlgoMatch and accelerated sFlow. Its 36 QSFP100 ports run at 100G, 50G, 40G, 25G or 10G, for up to 36x 100G, 72x 50G, 36x 40G or 144x 25G or 10G.

It forwards up to 3.34 billion packets per second with system latency under 4 microseconds at 64 bytes. Arista's spec table lists a 24 GB packet buffer, while the description text gives 16 GB.

Power draw is 830 W typical and 894 W maximum. The card weighs 16.1 lb and measures 17.5 x 1.75 x 23 inches (W x H x D).

A new DCS-7500R2AK-36CQ-LC is also available.

Line cards and fabric modules are hot-swappable in Arista modular chassis, so you can add or replace one without powering the chassis down.

Keep blank covers in any empty slots so the chassis airflow stays balanced.
