- Protect serial equipment from surge damage using inline RS232 DB9 DCE suppression
- Preserve monitoring continuity with a compact protector for critical serial links
Keep serial-connected systems online with protection designed for the realities of legacy infrastructure. APC ProtectNet RS232 DB9 DCE sits inline between equipment and cable runs to help reduce the risk of surge-related damage on RS232 communication paths.
That matters in environments where serial ports still control UPS management, industrial devices, console access, or building systems. A failed DB9 connection can interrupt monitoring, delay response, or take a critical device out of service. This compact protector is built for those high-consequence links where replacement hardware, downtime, and troubleshooting cost far more than the accessory itself.
For teams maintaining mixed-generation infrastructure, ProtectNet offers a practical way to harden vulnerable endpoints without redesigning the system. It is a targeted safeguard for serial connectivity, not a generic power strip, and that specificity is what makes it valuable in enterprise and industrial deployments.
Ideal For
- UPS management ports in server rooms and network closets
- Industrial control systems using RS232 serial communication
- Console access protection for routers, switches, and appliances
- Building automation or monitoring equipment with DB9 DCE connections
Why This Product
- 1Serial-line protection versus general-purpose power strips
