NEW Arista DCS-7500E-12CQ-LC 7500E Series 12x 100GB QSFP28 Switch Line Card

The DCS-7500E-12CQ-LC provides 12 QSFP ports that run at 40GbE or 100GbE in Arista 7500E chassis. Ports can also break out to 10GbE, for up to 48 10GbE interfaces on the card.

It installs in the 7504E and 7508E (DCS-7504 and DCS-7508). Arista notes that 7504R and 7508R chassis also accept 7500E cards, which helps when a site is moving between fabric generations.

The card is rated at 3.84 Tbps with system latency under 4 microseconds for 64-byte packets. Like other 7500E cards it uses deep buffering, with 18 GB of packet buffer to absorb bursts and incast traffic in storage and spine roles.

Power draw is 414 W typical and 486 W maximum. The card weighs 14 lb and measures 17.5 x 1.75 x 23 inches (W x H x D). Using standard pluggable QSFP optics rather than embedded ones lets you choose SR4, LR4 or other reach types per port, and replace a single optic without touching the card.

A seller refurbished DCS-7500E-12CQ-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-12CQ-LC is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
