Are all optical ports on the switch working
Not all optics are universally compatible with every switch, router, or access point. Consult your System Engineer (SE) or Vendor Technical Assistance Center (TAC) if you're unsure. We are experiencing issues with our optical ports between. Hello, from your output I can't see which type of QSFP you have installed, your QFX discovers. @LapointeMichel that known EX2300. When optical modules operate on a switch, it is usually necessary to read the module's internal information to understand its working status—such as connection status and real-time metrics like optical power and temperature. The capabilities of these devices are vast. This document describes how to determine why a port or interface experiences problems. Use the show interface status command to check if the corresponding port is Linkup. [pdf]
Control the access to the switch ports
To block unauthorized access to switch ports, switches support a feature called port security. This feature allows you to configure which devices are allowed or blocked on each port. A VLAN is a switched network that is logically segmented by function, project team, or application, without regard to the physical locations of the users. In today's topic we will learn about switch port mode access and how its configuration is done on Cisco switches. This can be a security risk when users connect. In the following we explain the four methods (port-based, single, multi, and MAC-based) and we illustrate the usage scenarios for each one. [pdf]FAQs about Control the access to the switch ports

How to inspect a power distribution box during installation
Check name plate, labelling, ID tags and warning signs correct to drawings / data sheets. Holding down arrangement correct and secure as per manufactures specification. Choose the right box based on environment (indoor/outdoor), load capacity, and durability. Ensure safe placement: install in. Regular inspection & testing of electrical panels is essential for assuring safety, dependability, and peak performance in any electrical system. This detailed electrical panel testing checklist explains the most important areas that must be assessed during the testing procedure. Inspect circuit breakers for proper operation. Verify the functionality of surge protection devices. [pdf]
How to arrange and layout industrial power distribution boxes
The distribution box should be installed in an area close to the power supply to reduce power loss and ensure safety. Avoid installing in a humid and corrosive environment to prevent equipment damage. Select a well-ventilated and dry place to avoid poor heat dissipation causing. In industrial power distribution systems, cable distribution boxes (also known as power distributor boxes, distribution electrical boxes, or electrical power distribution boxes) are the core hub of power transmission, branching, and protection.
