ENTERASYS STK-RPS-150PS Power Supply Module

I. Overview

ENTERASYS STK-RPS-150PS is a redundant power supply module specially designed for the A4 series of Ethernet managed switches from ENTERASYS. It plays a crucial role in the field of power supply guarantee for network equipment. In today's complex network environments with extremely high stability requirements, ensuring the continuous and stable operation of switches is of vital importance, and STK-RPS-150PS is created precisely for this purpose, providing a solid backup for the reliable power supply of switches.

II. Technical Parameters

• 
  

• Output Characteristics: This module can output a stable 12V DC, with a maximum output power of up to 150 watts. This power level can well meet the power demand of most A4 series switches during normal operation and when dealing with certain load fluctuations. Whether it is driving port-dense 24-port copper switches, 24-port fiber switches with higher data transmission requirements, or 8-port copper/8-port fiber hybrid switches, STK-RPS-150PS can stably output power to ensure the normal operation of the equipment.

• Input Characteristics: It has a wide input voltage range, supporting 100-240V AC input. This feature enables the power module to have excellent adaptability. It can be easily connected to the local power grid in regions using 110V standard voltage or 220V standard voltage, providing suitable power for the switch without the need for additional complex voltage conversion equipment, which greatly enhances the product's applicability in different regions around the world.

• Physical Specifications: The product has a net width of 53 mm, a net height of 125 mm, and a net depth (length) of 260 mm. The overall shape is compact and reasonable in design, facilitating installation and layout inside various switch chassis without occupying too much space, which helps keep the interior of the network cabinet neat and orderly, and also facilitates coordination with other equipment.

III. Functional Features

• 
  

• Hot-Swappable Function: STK-RPS-150PS has the hot-swappable feature, which means that during the normal operation of the switch, maintenance personnel can safely replace or add the power module without turning off the switch. The hot-swappable function greatly improves the availability and maintenance convenience of the system. In traditional network maintenance scenarios, if the power module fails, turning off the switch for replacement may cause interruption of network services and affect the normal operation of business. With the hot-swappable function of STK-RPS-150PS, maintenance personnel can quickly complete the module replacement without interrupting network traffic, significantly reducing maintenance time and potential losses caused by network failures.

• Status Indication Function: There is a status LED indicator on the front panel of the power module. Through different display states, this indicator can intuitively feedback the working status of the power module to users. When the LED indicator is steadily green, it indicates that the power module is operating normally and stably supplying power to the switch; if the indicator is flashing, it may mean that there are some abnormal conditions in the power module, such as output power fluctuations, excessive temperature, etc., reminding users to conduct inspection and maintenance in a timely manner; if the indicator is off, it usually means that the power module is not working normally, and further investigation of the cause of the failure may be required, such as whether the power connection is loose, whether the module itself is damaged, etc. Through this simple and intuitive status indication function, users can quickly understand the system's power status, timely detect potential problems and take corresponding measures.

• Redundant Power Supply Guarantee: As a redundant power supply module, STK-RPS-150PS plays a core role in ensuring the stability of power supply for network equipment. When the internal power supply of the switch fails, STK-RPS-150PS can quickly and automatically switch to take on the responsibility of supplying power to the switch, ensuring that the switch continues to operate without interrupting network traffic. In addition, the internal power supply and STK-RPS-150PS each have independent AC power connections, and users can connect them to different AC power circuits respectively, further enhancing the redundancy of the AC power supply. This dual redundancy design greatly improves the reliability of the switch's power supply system, effectively reducing the risk of network paralysis due to power supply failures, which is of vital significance for industry application scenarios with extremely high requirements for network stability such as finance, medical care, and transportation.

IV. Compatibility

STK-RPS-150PS exhibits good compatibility and can perfectly adapt to a variety of A4 series and some C series managed switches. Whether it is a 24-port copper switch (such as model P0973JM), which is widely used in wired network connections to provide stable network access for a large number of terminal devices; a 24-port fiber switch (such as model P0973JN) that focuses on high-speed, long-distance data transmission, suitable for scenarios with strict requirements on transmission rate and distance such as data center backbone networks; or an 8-port copper/8-port fiber switch (such as model P0973JP) that has both interface types to flexibly meet different network cabling needs, STK-RPS-150PS can work in coordination with them, providing reliable redundant power supply support for various switches and fully exerting its function of ensuring stable network operation.

V. Application Scenarios

• 
  

• Enterprise Network Core Layer: In the enterprise network architecture, core layer switches undertake the key tasks of high-speed data forwarding and aggregation, and their stability directly affects the operating efficiency of the entire enterprise network. STK-RPS-150PS can be used as a redundant power supply module for core layer switches, ensuring that when the internal power supply fails suddenly, the core layer switches can still operate continuously and stably, guaranteeing the normal transmission of key business data of the enterprise, and avoiding losses such as business stagnation and production delays caused by network interruption. For example, in large manufacturing enterprises, core layer switches are connected to network equipment in various production workshops and important facilities such as servers in the enterprise office area. STK-RPS-150PS can provide reliable power guarantee for them, maintaining the normal operation of key business systems such as production automation systems and enterprise resource planning (ERP) systems.

• Data Centers: As a hub for massive data storage, processing, and exchange, data centers have nearly strict requirements on the reliability of network equipment. Switches, as core components of data center networks, their power supply stability is crucial. STK-RPS-150PS can provide redundant power supplies for switches in data centers, effectively dealing with possible power supply failures. In cloud computing data centers, numerous virtual machines and containers rely on the network for data interaction. Once a switch shuts down due to power supply problems, it will cause a large number of cloud services to be interrupted, affecting the user experience of many users. By deploying STK-RPS-150PS, the fault tolerance of the data center network can be significantly improved, ensuring that the data center always maintains an efficient and stable operating state, providing reliable service guarantees for cloud service providers and users.

• Financial Institution Networks: The financial industry has extremely high requirements on network stability and security. Any short-term network interruption may lead to serious consequences such as transaction failures and customer information leakage. In the networks of financial institutions such as banks and stock exchanges, switches are responsible for connecting various transaction terminals, servers, and communication equipment with external financial networks. STK-RPS-150PS can provide reliable redundant power supplies for these switches, ensuring the uninterrupted operation of financial transaction systems in the face of internal power supply failures or mains voltage fluctuations, ensuring the smooth progress of customer transactions, and maintaining the reputation of financial institutions and the interests of customers.
