Description

The Enterasys C2RPS-PSM is a robust and highly reliable Power Supply Module specifically designed for the Enterasys C2 (formerly C2G) series of chassis-based network switches, most notably for the C2G124-48 and C2G124-24 switches. This module serves as the primary power source, converting AC input voltage to the DC power required for the switch’s operation. The Enterasys C2RPS-PSM is engineered with a focus on network uptime and resilience, offering optional N+1 power redundancy when installed alongside the switch’s internal power supply. This allows critical network infrastructure to maintain continuous operation even in the event of a single power supply failure, making it an essential component for building fault-tolerant network architectures in industrial and enterprise environments.

As part of the Enterasys (now Extreme Networks) portfolio of networking solutions, this module exemplifies the brand’s commitment to providing robust and manageable infrastructure. The value of the Enterasys C2RPS-PSM extends beyond mere power conversion; it enhances the overall availability of the network switch it supports. By providing power redundancy, it protects against power-related disruptions that could take down entire segments of an operational network, which is critical in environments like manufacturing plants where network downtime translates directly to production halts and financial loss. Its hot-swappable design further ensures that maintenance or replacement can be performed without powering down the switch, supporting continuous network operation.

Main Features and Advantages

The Enterasys C2RPS-PSM offers several critical features that ensure network reliability. Its foremost advantage is the support for N+1 power supply redundancy. When installed, it works in tandem with the switch’s built-in power supply to create a fault-tolerant power system. If one power supply fails, the other immediately takes over the entire load without any interruption to switch operation, thereby eliminating a single point of failure. This feature is indispensable for core networking equipment in Industrial Automation and Control Systems (IACS), where continuous connectivity for PLCs, DCS controllers, and HMIs is non-negotiable.

Furthermore, the module is designed for ease of use and maintenance. Its hot-swappable capability allows for the installation or removal of the Enterasys C2RPS-PSM without needing to power down the switch or disrupt network traffic. This facilitates quick replacement in the event of a failure and simplifies proactive maintenance. The unit incorporates comprehensive status monitoring through an LED indicator, providing immediate visual feedback on its operational state (AC OK, DC OK, Fault). The robust design, with a dedicated internal cooling fan, ensures stable operation and longevity even in demanding industrial environments where elevated temperatures can be a concern.

Application Field

The Enterasys C2RPS-PSM is deployed in any scenario where the availability of the connected network switch is critical to business or operational continuity. In industrial automation settings, these switches form the backbone of the control network, connecting PLCs, motor drives, HMIs, and distributed I/O systems. A network failure in such an environment can halt production lines, cause batch spoilage, or even lead to unsafe operating conditions. The Enterasys C2RPS-PSM mitigates this risk by ensuring the switch remains powered, thereby maintaining the flow of control data essential for continuous and safe operation.

Beyond the factory floor, this redundant power solution is equally vital in other mission-critical environments. It is used in utility substations for SCADA networks, in transportation systems for control and surveillance networks, and in enterprise data centers for network distribution layers. The Enterasys C2RPS-PSM is specifically chosen for applications that demand the highest level of network availability and where planned maintenance windows are scarce. It solves the problem of power supply fragility, providing a simple and effective layer of protection against one of the most common causes of hardware failure.
