What is the maximum PoE+ power delivery capacity?

The VSP 4450GTX-HT-PWR+ delivers 860 watts of PoE+ power at 0-50°C operating temperature and 400 watts at 50-70°C. With a single 1000W PSU, you can power up to 26 PoE+ ports simultaneously at maximum temperature, or more ports at lower temperatures. Adding a redundant PSU increases total available power for load sharing.

Can this switch operate in outdoor or high-temperature environments?

Yes. The VSP 4450GTX-HT-PWR+ is specifically engineered for 0-70°C operating range, making it suitable for industrial facilities, outdoor installations, and harsh climate locations. This extended temperature rating distinguishes it from standard commercial switches limited to 0-50°C operation.

What uplink options are available for core network connectivity?

The switch provides 2 x 1000BASE-SFP combo ports and 2 x 10GBASE-SFP+ uplink ports. The dual 10G SFP+ ports deliver 20 Gbps total uplink capacity, preventing bottlenecks when aggregating traffic from 48 access ports. Combo ports support both 1G SFPs and 100Base low-speed SFPs for flexible connectivity.

Does the switch support redundant power supplies?

Yes. The VSP 4450GTX-HT-PWR+ includes one 1000W AC PSU and supports an optional second field-replaceable PSU for N+1 redundancy. Both PSUs operate independently with load-sharing capability, enabling hot-swap replacement without service interruption or downtime.

What is the switching capacity and throughput performance?

The VSP 4450GTX-HT-PWR+ delivers 184 Gbps non-blocking switching capacity with a 1.2 GHz system CPU. This ensures consistent performance across all 50 ports simultaneously without congestion, supporting bandwidth-intensive applications and high-density device deployments.

What compliance certifications does this switch hold?

The switch meets CE (EN55022:2006, EN55024), FCC Part 15, ICES-003 (Canada), VCCI (Japan), AN/NZS 3548 (Australia/New Zealand), CNS13438 (Taiwan), MIC (Korea), and Anatel (Brazil) EMC standards. These certifications ensure regulatory compliance across global markets and industrial environments.

What is the expected lifespan and reliability rating?

The VSP 4450GTX-HT-PWR+ has an MTBF (Mean Time Between Failures) rating of 214,542 to 311,104 hours, translating to approximately 24-35 years of expected service life. This enterprise-grade reliability supports mission-critical deployments with predictable lifecycle planning and reduced maintenance costs.
