Buying Guide: Key Purchase Considerations
Power Capacity and Runtime
Assess total connected load in your network rack and choose a UPS with headroom to handle startup surges and growth. Consider models with expandable runtimes via external batteries if uptime needs may grow during outages.
Waveform Type and AVR
Pure sine wave output is preferred for sensitive server gear and switching power supplies. Automatic Voltage Regulation (AVR) stabilizes voltage without discharging batteries, extending run time during mild fluctuations.
Form Factor and Rack Compatibility
Select 2U or 4U rack-mountable units based on your rack depth, mounting clearance, and cable management. Some units can be used as towers with adapters, offering flexibility for growing networks.
Management and Networking
Look for USB, Serial, or network card options for remote monitoring, SNMP support, and integration with centralized power management software. SmartConnect features enable remote configuration and status checks.
Expandability and Lifecycle
Consider models with external battery packs or lithium-ion chemistry for longer service life and reduced maintenance. Check compatibility with your existing UPS management ecosystem and warranty terms.
Protection and Outlets
Ensure enough outlets and surge protection for networking devices, switches, and servers. Verify the arrangement (outlets grouped by battery-backed status) to prioritize critical equipment during outages.
