The SFP-10G-RA-1G-LX and SFP-10G-RA-1G-SX transceivers are rate adapting SFP+ transceivers with internal clause 37 auto-negotiation (AN) support. The transceiver host interface is 10G XFI and the module rate adapts in the egress direction from 10G to 1G before transmitting data on the attached fiber. In the ingress direction it rate adapts the received 1G data to 10G before sending to the host switch. This allows 1000BASE-LX and 1000BASE-SX support on switches which do not natively support 1G operation.

A secure erase is generally defined as a command (or set of commands) that deliberately, permanently and irreversibly remove/destroy the data stored on a storage device, rendering that data unrecoverable. This feature securely erases the flash and optional SSD storage device(s) within an Arista switch. Specifically, it will secure erase the storage devices whose partitions mount to /mnt/crash, /mnt/drive, and /mnt/flash (as applicable). Then, it repartitions these storage devices and re-creates the filesystems for each of their partitions. In other words, the partition table of each storage device will be the exact same as before this secure erase procedure (MBR gets destroyed during a secure erase); each partition will have the same filesystem type and partition label, and be mounted to the same mount point with the same options. This makes it possible to boot EOS again; simply install a new boot-config and EOS SWI, then reboot (which can be done through Aboot/fullrecover).
