The **SRCOOLNET2LX** is an SNMP/Network Management Card specifically designed for Tripp Lite’s SRCOOL12K and SRCOOL7KRM portable cooling units. It functions as the "brain" that connects the cooling hardware to a digital network. --- ### 1. Key Electronic Components & Interfaces The SRCOOLNET2LX consists of several critical electronic parts that enable remote monitoring and control: | Component | Function | | :--- | :--- | | **Microprocessor** | The central logic unit that processes temperature data and executes SNMP protocols. | | **RJ45 Ethernet Port** | Provides the physical connection to the LAN (10/100 Mbps) for network communication. | | **Mini-USB Port** | Used for local configuration, firmware updates, and initial IP setup. | | **E2 Environmental Port** | A specialized interface for connecting external sensors (e.g., E2MTU) to monitor temperature and humidity. | | **Status LEDs** | Indicators for Link, Activity, and Status (Health/Power). | --- ### 2. Functional Architecture The electronics are designed to bridge the gap between physical cooling and digital management systems. * **Logic Integration:** It interfaces directly with the cooling unit's internal control board to command the compressor and fan speed. * **Power Supply:** It draws low-voltage DC power directly from the expansion slot of the cooling unit; no external power brick is required. * **Sensor Logic:** The E2 port uses a serial communication protocol to daisy-chain environmental sensors, allowing the card to act as a hub for climate data. --- ### 3. Technical Specifications Below are the electronic and environmental specs for the card: | Feature | Specification | | :--- | :--- | | **Protocol Support** | HTTP, HTTPS, SSH, SNMPv1, SNMPv2c, SNMPv3, SMTP | | **Network Speed** | 10/100 Mbps Auto-sensing | | **Configuration** | Web Browser, Telnet, CLI | | **Form Factor** | Internal Plug-in Card | --- ### 4. Code / API Interaction The card supports programmatic control. For example, retrieving status via SNMP might look like this conceptually: ```bash # Example SNMP Get request for temperature (Conceptual) snmpget -v 3 -u user -l authPriv -a SHA -A password123 [IP_ADDRESS] TRIPP-LITE-COOLING-MIB::tempStatus.0 ``` ---
