Description
Foxboro P0973JM
Technical Specifications
- Port Configuration: 24 x 100Base-TX ports (RJ-45), 2 x fixed 10/100/1000 ports, 2 x 1000Base-X Gigabit uplink ports (SFP).
- Power Supply: Internal AC input (100-240V AC, 50-60Hz) with support for external redundant power connections.
- Power Consumption: Maximum power consumption of 66 Watts, with a maximum heat dissipation of 224 BTU/hr.
- Supported Standards: IEEE 802.1q VLAN, IEEE 802.1d STP, IEEE 802.1p QoS, IEEE 802.1w RSTP, IEEE 802.3u, IEEE 802.3z, IEEE 802.3ab.
Functional Features
- Full-Duplex Operation: Supports full-duplex communication to maximize data transmission efficiency.
- VLAN Support: Enables flexible network management through Virtual Local Area Network configurations.
- Network Management: Fully manageable via a local console port or SNMP/RMON-based management applications.
- Port Mirroring & Diagnostics: Allows redirection of local network traffic to an external probe for detailed analysis and troubleshooting.
- High Reliability: Eliminates single points of failure when installed with an optional redundant power supply.
Application Scenarios
Widely used in industrial control, process control and monitoring, factory automation, intelligent networking of PLC controllers, automated testing, and data acquisition systems.
Performance Parameters
- Maximum Current: 0.5A at 110V AC, 0.47A at 220V AC.
- Environmental Adaptability: Operating temperature from 0°C to +50°C, storage temperature from -40°C to +70°C, and relative humidity from 5% to 95% (non-condensing).
Material Composition
Constructed with industrial-grade electronic components and a rugged metal enclosure. The internal circuit boards are specially treated to withstand electromagnetic interference and temperature fluctuations typical in industrial environments.
Structural Characteristics
Features a standard 19-inch rack-mountable design, with options for desktop or shelf mounting. The front panel includes clear port labeling and status indicator LEDs for easy monitoring.
Working Principle
Operating as a Layer 2 switch, it filters, floods, and forwards data frames at the data link layer using a MAC address table. It utilizes Spanning Tree Protocol (STP/RSTP) to prevent network loops and employs VLAN technology to isolate broadcast domains.
Installation Requirements
Can be installed in a standard 19-inch cabinet with adequate ventilation. If using a redundant power supply, the external power module must be connected according to specifications.
Usage Precautions
- Ensure the power supply voltage is within the rated range (100-240V AC).
- Avoid operating the device outside the specified temperature and humidity ranges.
- Always back up the current running configuration before making configuration changes.
