Description

The Arista 7500R3 36-port 100G QSFP100 line card is a wirespeed module for the 7500R3 Series modular chassis. It suits large-scale data centre spine and leaf designs, cloud and EVPN/VXLAN overlay networks, internet peering, data centre interconnect and carrier edge or core transport.

Each card provides 36 QSFP100 ports with 3.6 Tbps of forwarding, 2 Bpps of wire-speed performance and 8 GB of deep packet buffer. Ports also run in 50G, 25G and 10G modes with suitable optics or breakout cables, up to 72 x 50G or 96 x 25G/10G. This is the standard routes (non-K) card, with 1450k IPv4 unicast routes in the L3 profile, extended by FlexRoute. Typical power draw is 442 W (576 W maximum), excluding optics.

The card installs in the DCS-7512N, DCS-7508N and DCS-7504N chassis alongside the 7500R3 fabric modules and Supervisor-2 (DCS-7500-SUP2), and runs Arista EOS from the supervisor. It is powered from the chassis power supplies (PWR-3KT-AC-RED, PWR-3KT-HV-RED or PWR-3K-DC-RED).

FAQs

Q: Which chassis does this line card fit?
A: It installs in the Arista DCS-7512N, DCS-7508N and DCS-7504N chassis, together with the 7500R3 fabric modules and Supervisor-2 (DCS-7500-SUP2).

Q: Does it need a separate licence?
A: No separate licence is specified for the line card hardware. It runs Arista EOS from the DCS-7500-SUP2 supervisor module.

Q: What power does it draw?
A: It draws 442 W typical and 576 W maximum, excluding optics. Power comes from the chassis power supplies, PWR-3KT-AC-RED, PWR-3KT-HV-RED or PWR-3K-DC-RED.

Q: Can the ports run at speeds below 100G?
A: Yes. The QSFP100 ports also support 40G, and 50G, 25G and 10G modes with suitable optics or breakout cables, for up to 96 interfaces per card.

Q: How does this differ from the DCS-7500R3K-36CQ-LC?
A: This DCS-7500R3-36CQ-LC is the standard routes (non-K) card with the same 36-port layout. The 7500R3K card is the large-route sibling.
