The DCS-7800R3-48CQ-LC is a 48-port 100GbE QSFP100 wire-speed line card for the Arista 7800R3 Series. It fits the 7804R3, 7808R3, 7812R3, 7816R3 and 7816LR3.
Ports run at 100G or 40G, or break out for up to 96x 50G, 96x 25G or 96x 10G. Up to 48 100G or 48 40G interfaces are supported per card, which makes it a dense 100G option for spine, aggregation and routing roles.
Arista rates the card at 4.8 Tbps (9.6 Tbps full duplex) and 2 billion packets per second, with system latency under 4 microseconds for 64-byte packets. It carries an 8 GB packet buffer. MACsec is not supported on this card; the 48CQM version adds it.
Power draw is 398 W typical and 462 W maximum, much lower than the 400G cards, which helps when a chassis is power-limited. The card weighs 20 lb and measures 18.9 x 2.1 x 17.8 inches (W x H x D).
A seller refurbished DCS-7800R3-48CQ-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-7800R3-48CQ-LC is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
