Description

The Arista 7368X4 4-port 400G QSFP-DD switch module is a line card for the modular 7368X4 data centre switch, and is also listed for 7358X and 7289R Series chassis. It suits hyperscale cloud, AI/ML and I/O-intensive spine and leaf deployments that need high-density 100G and 400G connectivity.

The module provides 4 x QSFP-DD ports running up to 4 x 400GbE. It also supports 4x100G and 2x200G modes, and can use existing 100G optics and cables alongside QSFP-DD 400G optics and cables. Power draw is 72 W typical and 140 W maximum with 4.5 W optics, supplied from the chassis. A 7368X4 chassis has 8 line card slots, so it scales to as many as 32 x 400G ports or 128 x 100G ports.

The module requires a compatible chassis, supervisor and switch card running EOS 4.22.0 or later. Related modules for the same platform include the DCS-7368-4P (4 x OSFP 400G), DCS-7368-16C (16 x QSFP28) and DCS-7368-16S (16 x SFP28).

FAQs

Q: Which chassis does the DCS-7368-4D work in?
A: It is listed for the Arista 7368X4 chassis and also for 7358X and 7289R Series chassis. It needs a compatible chassis, supervisor and switch card running EOS 4.22.0 or later.

Q: Can it use 100G optics and cables?
A: Yes. The module takes QSFP-DD optics and cables for 400G, and existing 100G optics and cables can also be used. It supports 4x100G and 2x200G modes.

Q: How much power does the module draw?
A: It draws 72 W typical and up to 140 W with 4.5 W optics, powered from the chassis. The 7368X4 chassis uses PWR-1900 AC or DC power supplies in an N+N redundant arrangement.

Q: What licensing does it need?
A: The module itself needs a compatible chassis, supervisor and switch card running EOS 4.22.0 or later. The platform uses EOS feature licences, and an Enhanced L3 licence is available for BGP, OSPF, ISIS, PIM and NAT.

Q: How does it differ from the DCS-7368-4P?
A: The DCS-7368-4D provides 4 x 400G QSFP-DD ports, while the DCS-7368-4P provides 4 x 400G OSFP ports. Choose the one that matches your optics and cabling.
