Compatible Redundant Power Module

The Supersuperuncle 550W YM-7421D is a redundant power module built for the Juniper SSG-550M-SH security appliance. It supplies 550 watts of hot-swappable power to keep the system running if the primary unit fails. This module is for network administrators maintaining that specific Juniper platform. It is not for builders needing a standard ATX power supply or a different wattage.

Straightforward Hot-Swap Installation

The module slides into the dedicated chassis bay and locks with the built-in lever, so no tools or cable routing are required. Firmware compatibility with the SSG-550M-SH should be verified before deployment. A common issue is inserting the unit without fully engaging the latch, which prevents the appliance from recognising the redundant source.
