A UPS supplies temporary battery power to selected equipment. Protecting only the router may not keep the network usable if the modem, switches, access points, or local application server lose power.
Map the critical power chain
List the ISP handoff device, gateway, core switches, access points, phones, and relevant controllers or recorders. Identify which endpoints receive PoE from a switch and which use separate power adapters. Equipment in another building may need its own protected power.
Size for the actual load
- Record normal power use and expected PoE load.
- Define the runtime needed for a short outage or orderly shutdown.
- Use the manufacturer's runtime data for the intended load, not only the UPS's VA rating.
- Check outlet count, installation environment, and electrical requirements.
- Allow for battery aging and planned equipment growth.
A UPS does not guarantee that the ISP's outside infrastructure will remain online. An equipment power-redundancy product also should not be assumed to include a battery or replace a UPS; confirm the exact device's function.
Maintain and test
Record battery age, test results, alarms, and replacement responsibilities. Test the arrangement under controlled conditions with appropriate authorization. For servers or recording systems, confirm the shutdown behavior and recovery sequence.
Involve a qualified electrician where electrical work is required. Keep the UPS accessible and follow the manufacturer's loading and ventilation requirements rather than connecting additional equipment casually.
