Arista 36-port 100GbE line card

The Arista DCS-7500R2A-36CQ-LC is a 36-port 100GbE QSFP28 line card built for the Arista 7500R chassis. It targets network operators who need high-density 100GbE connectivity in a modular core or aggregation layer.

QSFP28 port density and cabling limits

Each of the 36 ports accepts a QSFP28 transceiver for 100GbE links. The card does not support hot-swap removal, so maintenance windows must be planned. AlgoMatch capability is included, distinguishing it from the non-A variant.

Chassis slot and transceivers to verify

Confirm an available line-card slot in a compatible Arista 7500R chassis before ordering. Source 36 QSFP28 optics or direct-attach cables that match the intended reach and fiber type for each port.

Klausimai apie šią prekę

What is the difference between this DCS-7500R2A-36CQ-LC and the DCS-7500R2-36CQ-LC?

This model includes the AlgoMatch feature that the non-A variant lacks, while both provide 36 ports of 100GbE QSFP28 connectivity for the 7500R chassis.

What does 100GbE QSFP28 mean for actual throughput on each port?

Each of the 36 ports delivers 100 gigabits per second of line-rate Ethernet traffic when populated with compatible QSFP100 optics or cables.

Which chassis slots accept this line card and are there any slot restrictions?

The card is designed for the Arista DCS-7500R chassis; it is not hot-swappable, so installation requires a planned maintenance window.
