ASA-PWR-DC Use Case
Enterprise Branch Office Redundant DC Power for ASA 5545-X/5555-X
In a global finance firm’s distributed branch offices, dual ASA-PWR-DC modules on ASA 5545-X appliances integrate with existing –48 V DC infrastructure to deliver seamless failover. This implementation drives 99.99% firewall uptime during utility outages, simplifies centralized power management, and meets rigorous compliance standards for financial data security.
Telecom Edge Network Continuity with DC-Powered ASA 5555-X
A leading telecom carrier deploys ASA-PWR-DC on ASA 5555-X firewalls at cellular base stations running on –48 V battery backup. The result is uninterrupted VPN tunnels for remote tower management, 5-nines availability across edge sites, and reduced MTTR by 70%, ensuring subscriber data integrity under all power conditions.
Industrial OT Network Protection via ASA 5545-X DC Power Supply
In a 24/7 manufacturing plant, ASA-PWR-DC modules power ASA 5545-X appliances on 24 V DC distribution buses to secure SCADA and PLC communications. This approach eliminates single points of failure, maintains continuous operational technology (OT) firewall enforcement, and aligns with UL and IEC industrial power standards for enhanced facility resilience.
