Key specifications

• Power output: 750W
• Input type: AC
• Compatibility: Catalyst 3750-E, 3560-E, and RPS 230

How to use

To install the power supply, ensure the switch or RPS 230 unit is powered down and disconnected from the main electrical source. Carefully slide the module into the designated power supply bay on the back of the device until it is firmly seated. Secure the module using the integrated locking mechanism or screws provided on the chassis. Once installed, connect the appropriate AC power cable to the module and then to a grounded electrical outlet before powering on the device.

What to consider before purchase

• Verify the specific model number of your switch to ensure compatibility.
• Check the power requirements of your current network configuration.
• Ensure that the physical dimensions of the power bay match the module.

Usage recommendations

Always use a high-quality, properly rated power cable to connect the unit to your power source to ensure optimal performance and safety. Periodically inspect the power supply fan and ventilation areas to prevent dust accumulation and ensure proper cooling.
