Arista DCS-7368-4D | 7368X4 4-Port 400G Module, QSFP-DD, Data Center

Q: What chassis is the DCS-7368-4D module compatible with?
A: The DCS-7368-4D is designed for use with the Arista 7368X4 Series modular chassis (DCS-7368-CH). The chassis supports up to 8 interface modules and delivers 3.2 Tbps per slot, enabling flexible configurations for high-density data center deployments.

Q: Can this module support lower-speed optics?
A: Yes, the DCS-7368-4D supports backward compatibility with 100G, 200G, and 40G QSFP optics and cables. Each port can be configured for different speed modes, allowing for migration and mixed-speed environments within the same module.

Q: Is the module hot-swappable?
A: Yes, the DCS-7368-4D is fully hot-swappable and field-replaceable, allowing for maintenance and upgrades without disrupting the chassis or network operations. The 7368X4 system is optimized for simple serviceability and provisioning.

Q: What is the typical latency for this module?
A: The 7368X4 Series supports port-to-port latency as low as 700 nanoseconds in cut-through mode, with a 64 MB shared packet buffer for superior burst absorption, making it ideal for low-latency data center applications.

Q: What software is required to operate this module?
A: The DCS-7368-4D requires Arista EOS version 4.22.0 or later. The module is managed through the 7368X4 supervisor card (DCS-7368-SUP), which runs EOS on a quad-core CPU with 32GB of memory.
