Due to unexpected end of sales of a particular component on the SRX5K-SPC-4-15-320, we will need to transition to a new component in late August or early September 2016. In order to accommodate this new component a JUNOS upgrade will be required, and all customers are encouraged to upgrade as soon as possible.

The model number SRX5K-SPC-4-15-320 will remain the same after a new component is introduced. New production units with the same model number will ship from late August 2016, and those parts supplied from RMA spare depots can have a new component anytime thereafter.

It is highly recommended that customers qualify and upgrade to a Junos as soon as possible that can run both current version of SRX5K-SPC4-15-320 and newer revision of it which will be gradually phased in Q3 2016.

Upgrade Junos to one of the following releases or higher.

12.1X44-D45
12.1X46-D35
12.1X47-D20
12.3X48-D10
15.1X49-D10
