JAK-20-20 Ericsson Ericsson RBS HDD

The Ericsson JAK-20-20 is a hard disk drive module designed specifically for use with the HDU7 (Hard Disk Unit 7) card. This storage component provides data logging, configuration storage, and operational data retention capabilities within Ericsson mobile network infrastructure equipment.

The HDU7 card and its associated HDD are typically deployed in Ericsson RBS (Radio Base Station) systems, where they handle software storage, call data records, and system configuration files. The hard drive ensures persistent storage for critical operational parameters and network management data.

This is a legacy component from Ericsson’s earlier generation of mobile network equipment. While largely superseded by solid-state storage in newer platforms, the JAK-20-20 remains essential for maintaining and extending the service life of existing RBS installations that utilise HDU7 cards.
