Frequently Asked Questions
What types of devices can be powered by this switch?
The X440-G2-12p-10GE4 can power any IEEE 802.3af/at compliant device, including wireless access points, IP cameras, VoIP phones, and digital signage. With 30W available per port, it supports high-power devices such as 802.11ax access points and PTZ cameras.
How does the upgrade process work for the 10GbE ports?
The four SFP ports can be upgraded through a software license purchased from Extreme Networks. Once applied, the ports immediately support 10GbE SFP+ transceivers without requiring hardware changes or system downtime.
Can this switch be stacked with other Extreme Networks models?
Yes, through SummitStack-V technology, this switch can be stacked with other X440-G2 models as well as X450-G2, X460-G2, X670-G2, and X770 switches, provided all units run the same ExtremeXOS version.
What redundancy options are available for power?
The switch supports external redundant power supplies (RPS) through its dedicated RPS port. The RPS-90 unit provides 90W of backup power, ensuring continuous operation during primary power source failure.
Installation Considerations
- Ensure adequate ventilation around the switch, maintaining at least 2 inches of clearance on all sides for proper airflow, especially when operating at high PoE loads
- Calculate total power requirements for all connected PoE devices to ensure they do not exceed the 200W total budget
- Use only Extreme Networks certified SFP/SFP+ modules to ensure compatibility and maintain warranty coverage
- When deploying in environments with temperature fluctuations, monitor ambient conditions to remain within the 0°C to 50°C operational range
- For stacking configurations, verify all switches are running compatible ExtremeXOS versions before establishing stack connections
- Implement proper cabling practices, using Category 6 or better cabling for Gigabit connections and appropriate fiber for SFP modules
