NEW Arista DCS-7500R2M-36CQ-LC 36x 100GB QSFP100 MACsec Switch Line Card

The DCS-7500R2M-36CQ-LC is a 7500R2 line card with 36 100GbE QSFP100 ports and line-rate MACsec encryption. Ports run at 100G or 40G, for up to 36 of either. Unlike the R2AM version, this card does not include AlgoMatch.

MACsec uses GCM-AES-XPN with 128-bit keys supported (256-bit not yet supported), runs in 100G mode only, and does not work over DAC cables. It requires an Arista MACsec license, sold separately (LIC-MOD-1-MACSEC).

It installs in the 7504R, 7508R, 7512R and 7516R (DCS-7504, DCS-7508, DCS-7504N, DCS-7508N, DCS-7512N and DCS-7516N). Arista rates the card at up to 7.2 Tbps with system latency under 4 microseconds at 64 bytes, and it has a 16 GB packet buffer.

Power draw is 683 W typical and 941 W maximum, lower than the AlgoMatch version. The card weighs 17.4 lb and measures 17.5 x 1.75 x 23 inches (W x H x D). Choose it when inter-site links need encryption but complex hardware filtering is not required.

A seller refurbished DCS-7500R2M-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.

This DCS-7500R2M-36CQ-LC is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
