How to make a small bend in a cable tray

You can buy a manufactured 90 degree bend or make one on a cable tray bending machine but in this video I show you how to make one using a metal bar. Since the jaws of the bolt cutter drags a layer of zinc across the cut end and forms a protective layer. To remove the lip we can use a small hand grinder (B) or a file (C), but care must be taken when. [pdf]

How is the pricing for pigtail fixing determined

How is the pricing for pigtail fixing determined

Key price determinants include the length of aluminum-to-copper pigtailing runs, the number of outlets or switches, and whether the service panel requires updates to meet current codes. In areas with strict electrical codes or high labor costs, expect toward the top of the ranges. The main cost drivers are labor time, materials for copper pigtails and connectors, and any permitting or code compliance needs. [pdf]

How to use an optical time domain reflectometer Glink

This manual provides basic instructions for the use of EXFO OTDR series Optical Time Domain Reflectometers, including the setup of the device, measurement of optical cables, analysis of measurement results and generation of reports. Fiber optic testing is one of the crucial stages in evaluating optical networks. By measuring backscattered light, it reveals fiber length, splice loss, connector reflections, and break locations. in cable TV, LAN, metropolitan networks or long-haul. [pdf]

How to display fiber optic interfaces on a switch

How to display fiber optic interfaces on a switch

show interface <interface-type> <interface-number> It displays port negotiation speed, transceiver type, link status (UP indicates normal link) and traffic statistics for fault analysis. How to check fiber ports in cisco switch? 1. Enter the privileged EXEC mode by typing "enable" and providing the enable. This article provides instructions on how to view the Optical Module Status on your switch through the Command Line Interface (CLI). Generally, you can use those commands to view specific transceiver vendor names, types, wavelength, distance, Serial Number, Part Number, and DDM/DOM parameters. It's. This document describes how to troubleshoot fiber optic interfaces by addressing some of the fiber optic module and cabling specifications. [pdf]

How to straighten a small motherboard

How to straighten a small motherboard

The beauty of AMD's current PGA socket design is that once most pins are straight enough to fit the holes on the motherboard socket, they can be coaxed back into near-perfect alignment by closing the socket arm on the motherboard. The socket “grabs” the pins, further straightening. In this article, we will explore how to straighten CPU pins safely and effectively. This is why you'll sometimes see listings for newer CPUs that claim to be non-working because of bent pins. All hope is not lost! Bending back CPU pins is a somewhat obscure, slightly tedious process, but. CPU pin repair is the process of carefully straightening bent processor pins using precision tools to restore proper socket connection. [pdf]
