In petrochemical facility security, heavy-duty PTZ cameras with heaters, wipers, and long-range lasers are essential. However, when heaters activate in low temperatures, power consumption often exceeds the 30W PoE+ limit, causing camera reboots or PTZ lag.
Breaking the Power Bottleneck: 90W 802.3bt
Most industrial switches use the IEEE 802.3at (30W) standard. For industrial PTZ units with integrated defrosting, insufficient power redundancy is a primary cause of system instability.
- 90W High Power Output: All 8 copper ports on the Olycom IM-FP21008GW comply with IEEE 802.3bt, delivering up to 90W per port.
- 750W Power Budget: A robust power design supports multiple high-performance devices running at full load simultaneously.
- Adaptive Compatibility: It is backward compatible with IEEE 802.3af (15.4W) and 802.3at (30W), protecting existing surveillance investments.
Reliability Engineering for Harsh Industrial Conditions
Network equipment in petrochemical sites is often housed in outdoor enclosures, facing extreme heat and electrical surges.
- Physical Heat Dissipation: The switch features a ribbed chassis for improved thermal disbursement and user-programmable port thermal protection to prevent heat-induced damage.
- 6KV Surge Protection: Both UTP and fiber ports integrate 6KV surge protection to mitigate damage from lightning strikes.
- Environmental Durability: With an operating range of -40℃-75℃ and compliance with IEC 60068 standards for shock and vibration, it is built for the industrial floor.
Millisecond-Level Redundancy: ERPS Ring Technology
In critical infrastructure, network downtime due to a single link failure is unacceptable.
- Rapid Convergence: Utilizing ITU-T G.8032 ERPS, the system recovers from link failures in under 50ms.
- High-Bandwidth Backhaul: Dual SFP ports support up to 2.5G (2500Base-FX), ensuring 4K video streams remain fluid across the ring.
