FAQs

Q: What is included in the DCS-7388X5-32C-48DR-F system bundle?
A: This complete system bundle includes the 7388X5 chassis, 7388X5-BND bundle (2x AC power supplies, supervisor module with SSD, 7388X5 switch card, and fans), plus 32x 200G QSFP-DD and 48x 400G QSFP-DD transceivers with front-to-rear airflow. All active components are field-removable for ease of maintenance.

Q: What deployment scenarios is the 7388X5 series best suited for?
A: The 7388X5 is optimised for hyperscale cloud data centres, AI and machine learning clusters, and high-radix spine-leaf architectures requiring ultra-low latency, high throughput, and flexible 100G/200G/400G connectivity. It excels in both leaf and spine roles in large-scale multi-tier networks.

Q: Does this switch require additional software licensing for routing features?
A: The base Arista EOS feature set is included with the hardware. Advanced routing features such as BGP, OSPF, and multicast require the EOS Enhanced license, while BGP-EVPN for VXLAN requires the EOS Flex-route Lite license. CloudVision automation and visibility is available as a subscription.

Q: Can I mix different speed transceivers in the same chassis?
A: Yes, the 7388X5 supports a wide range of pluggable optics from 10G to 400G, allowing you to mix and match interface modules and transceiver types across the 8 I/O module slots based on your network requirements and migration path.

Q: What is the power consumption and redundancy of this system?
A: Typical power consumption is under 10W per 200G port. The system includes dual redundant hot-swappable AC power supplies with greater than 96% efficiency, supporting N+N power redundancy, and N+1 redundant hot-swappable fans for maximum uptime and serviceability.
