NEW Arista DCS-7548S-LC 7500 Series 48x 10GB SFP+ Switch Line Card

The Arista DCS-7548S-LC is a 48-port 10GbE SFP+ wire-speed line card for the first-generation Arista 7500 series modular switch. It installs in the DCS-7504 and DCS-7508 chassis, and every one of its 48 ports runs at full line rate into the chassis fabric, so the card suits dense 10G aggregation and data center spine roles.

Arista built the original 7500 platform around a matched set of common equipment. The DCS-7548S-LC sits alongside the DCS-7500-SUP supervisor and the DCS-7504-FM or DCS-7508-FM fabric modules, and Arista names the DCS-7500E-48S-LC 48-port 10GbE SFP+ 7500E line card as its second-generation counterpart. Before adding the card to an existing system, confirm which supervisor and fabric generation the chassis is running, since Arista does not publish a matrix for mixing first-generation cards with later fabrics.

For power planning, Arista lists a DCS-7504 with DCS-7548S-LC cards at 2124W typical and 2778W maximum, and a DCS-7508 with DCS-7548S-LC cards at 3806W typical and 4520W maximum. The ports accept SFP+ optics such as the SFP-10G-SR 10GBASE-SR multimode transceiver for short multimode runs. A status LED on the faceplate shows card health, and each port has its own link LED.

This DCS-7548S-LC line card is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
