Where a 10G port needs filling on an Arista switch — spares drawer, new turn-up, or a failed-module swap inside a maintenance window — the SFP-10G-DZ-40.56 covers it in the standard SFP form factor. It carries Arista-specific coding, so the host identifies it cleanly and no configuration step follows installation.
