  • Supervisor control for 7300 series chassis

Arista 7300 Supervisor Module

The Arista DCS-7300-SUP-D is a supervisor module built for the 7300 series chassis. It provides the control plane and management functions required to operate the switch fabric. Network engineers deploying or maintaining Arista 7300 platforms use this module to gain console and out-of-band access.

Management ports and storage

The module includes one RJ-45 RS-232 serial console port, two RJ-45 100/1000 management Ethernet ports and two USB 2.0 Type-A ports. An internal SSD stores configuration images and logs. The unit is not hot-swappable, so chassis power must be considered during replacement.

Chassis upgrade considerations

This module replaces a failed or outdated supervisor in an existing Arista 7300 chassis. The jump is worth it when the current supervisor lacks the SSD or the dual 100/1000 management interfaces. It is not for builders who need a hot-swappable supervisor or a different chassis family.

Questions about this item

How do I install the DCS-7300-SUP-D supervisor module into the 7300 chassis and which step is often missed?

Slide the module into the supervisor slot until the ejector levers engage, then tighten both captive screws to secure the electrical connection; the step most often missed is fully seating both screws, which leaves the management ports inactive.

What maintenance or replacement will the DCS-7300-SUP-D need over time?

The internal SSD stores logs and configuration; plan to monitor its health via SMART attributes and replace the module if the drive shows wear-out or unrecoverable errors.

What limit appears first when the DCS-7300-SUP-D runs under sustained load?

The management-plane CPU and 100/1000 RJ-45 ports become the bottleneck before the switching fabric, so sustained high-rate SNMP polling or syslog bursts will saturate the 1000 Mbps management links first.
