UM IP gateways. IPv6 support for UM IP gateways. Enabling and disabling a UM IP gateway. Overview of UM IP gateways. Traditionally, gateway is a term that describes a physical device that connects two incompatible networks.
SDXC. SDXC is the next version of the SD standard, which is designed to allow storage capacities from 32 GB to 2 TB (Terabytes). SDXC cards in current production have capacities up to 64 GB only. They are formatted with exFAT file format.
SDXC cards can be reformatted to use alternative file systems. For example, FAT32 supports volumes up to the SDXC's maximum theoretical capacity of 2 TB as well, and technically it can be used in an SDXC host device that can handle volumes larger than 32 GB, if the device can support the card's file system.
