Arista 7300 32-Port 40GbE Line Card

This Arista DCS-7300X-32Q-LC line card adds 32 QSFP+ ports running at 40 GbE to a compatible 7300 chassis. It is built for network operators who need high-density 40 GbE connectivity in a modular system.

Sustained load on 32 QSFP+ ports

The card is not hot-swappable, so maintenance requires a planned shutdown of the affected slot. Under continuous traffic the line card relies on the chassis cooling and power budget to maintain stable operation across all 32 ports.

Check chassis compatibility and slot availability

Verify that the target system is an Arista DCS-7300 chassis with the CAT-29607 designation before ordering. An empty line-card slot and sufficient chassis power headroom are also required for installation.

Questions about this item

How much power does the DCS-7300X-32Q-LC draw when all 32 ports run at 40GbE continuously?

The line card is rated for typical operation inside an Arista DCS-7300 chassis; power draw scales with the number of active QSFP+ modules and traffic load.

What chassis must I already own before this line card will function?

It installs only in an Arista DCS-7300 chassis, referenced as CAT-29607 in the compatibility note.

Will the DCS-7300X-32Q-LC work alongside older supervisor modules already in my 7300 chassis?

The card requires a compatible supervisor generation in the same DCS-7300 chassis; verify the supervisor model against Arista's supported matrix before mixing.
