Arista DCS-7300X-32Q-LC 7300X Series 32x 40GB QSFP+ Switch Line Card

The DCS-7300X-32Q-LC is a 32-port 40GbE QSFP+ line card for Arista 7300X Series chassis. It installs in the 7304X, 7308X and 7316X, which are the DCS-7304, DCS-7308 and DCS-7316 chassis fitted with Fabric-X modules. The card needs those Fabric-X modules (7304X-FM, 7308X-FM or 7316X-FM) to operate.

Each QSFP+ port runs at 40GbE or splits into four 10GbE links with breakout cables, so a single card can present up to 128 10GbE ports. That makes it useful both for 40G spine links and for dense 10G server aggregation in the same slot.

At the platform level Arista rates the line card at up to 2.56 Tbps and 1.92 billion packets per second, with latency below 2 microseconds. The card carries a 24 MB packet buffer.

Power draw is 219 W typical and 372 W maximum, which works out to under 12 W per 40G port. The card weighs 10.2 lb and measures 11.83 x 17.11 x 1.73 inches (W x H x D). Plan power supply capacity for the full chassis load before adding cards.

A new DCS-7300X-32Q-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 seller refurbished DCS-7300X-32Q-LC is tested, working, and covered by the NetworkTigers one-year warranty.
