FAQs

Q: What does HV mean in the PWR-3KT-HV-RED model designation?
A: HV stands for High Voltage, indicating this power supply supports both high-voltage AC and DC input options for maximum deployment flexibility in diverse datacenter power environments.

Q: Which Arista switch models are compatible with this power supply?
A: The PWR-3KT-HV-RED is compatible with Arista 7300 Series modular switches (DCS-7304, DCS-7308) and 7500N/7500R3 Series chassis (DCS-7504N, DCS-7508N, DCS-7512N, DCS-7516N).

Q: What does the red handle color indicate?
A: The red handle designates front-to-rear airflow direction, which is critical for proper thermal management in datacenter rack deployments. This must match your chassis and surrounding equipment airflow configuration.

Q: Can this power supply be hot-swapped?
A: Yes, the PWR-3KT-HV-RED supports hot-swap installation and removal, allowing maintenance and upgrades without powering down the switch, provided redundant power supplies are installed.

Q: What is the advantage of Titanium efficiency rating?
A: Titanium efficiency (94%+ typical) significantly reduces power consumption and heat generation compared to lower-rated PSUs, lowering operational costs and cooling requirements in 24/7 datacenter operations.
