The DCS-7500E-12CM-LC is a 7500E line card with 12 MXP ports using embedded 100GbE SR10 optics. Because the optics are built in, there are no transceivers to buy for these ports; you connect with MPO fiber cabling.
Each MXP port runs as 100G, 3x 40G or 12x 10G, for a maximum of 12 100GbE, 36 40GbE or 144 10GbE ports on one card. That flexibility makes it a dense 10G and 40G aggregation card as well as a 100G card.
It fits the 7504E and 7508E (DCS-7504 and DCS-7508), and 7504R and 7508R chassis also accept 7500E cards. It needs Fabric-E modules (DCS-7504E-FM or DCS-7508E-FM) or R-series fabric. Arista rates it at 3.84 Tbps per card with system latency under 4 microseconds for 64-byte packets.
The card has an 18 GB deep packet buffer. It draws 408 W typical and 495 W maximum, weighs 15.5 lb and measures 17.5 x 1.75 x 23 inches (W x H x D).
A seller refurbished DCS-7500E-12CM-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-7500E-12CM-LC is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
