2 4 Backup memory modules are installed in pairs and referred to as a backup
memory kit. Each module contains two batteries and either a 128 GB SSD
flash drive (small kit) or a 256 GB SSD flash drive (large kit).

batteries and the cache flash memory (SSD). The batteries keep the cache
active up to 32 minutes while the data is copied to the SSD.
