Our Process

Our Process: Preparation
Preparation

Once you accept your quote and confirm your order, we prepare by retrieving related parts and components from our inventory. Anything we do not currently have in stock is sourced.

Our Process: Receiving
Receiving

Upon receipt, all parts are visually inspected for damage and then photographed to document their condition. Parts acquired from vendors must meet our quality standards.

Our Process: Initial Testing
Initial Testing

Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.

Our Process: Refurbishment
Refurbishment

Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.

Our Process: Repair
Repair

Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.

Our Process: Final Testing
Final Testing

Industrial computer boards have all I/O connections rigorously tested to ensure that everything is working properly before the board is certified as ready to ship.

Our Process: Shipping
Shipping

After photos are taken to document the exterior condition of the part, it is packaged and sent to the customer. ESD-safe materials are used to protect sensitive equipment on its journey.

A power system that is comprised of a number of rectifiers could have difficulty restarting after a shutdown event because of the non-synchronized behavior of the individual The rectifier differentiates between internal faults that are rectifiers.

The FAULT LED, FAULT PIN or i2c alarm is not asserted for EXTERNAL FAULTS. Every attempt is made to annunciate A synchronous restart can be implemented by; External Faults. Some of these annunciations can be 1. Issuing a GLOBAL OFF and then ON command to all observed by looking at the input LEDs. These fault rectifiers, categorizations are predictive in nature and therefore there is a likelihood that a categorization may not have been 2 . Toggling Off and then ON the ON/OFF (ENABLE) signal made correctly. 3. Removing and reapplying input commercial power to the entire system.

The rectifier recognizes that certain transitionary states can occur before a final state is reached. The STATUS and multiple fans are used in the same rectifier. If the speed of Hot plug procedures the fans varies by more than 20% from each other, this is an indication of an impending fan wear out. Careful system control is recommended when hot plugging a rectifier into a live system. It takes about 15 seconds for a The goal is to identify problems early before a protective rectifier to configure its address on the bus based on the shutdown would occur that would take the rectifier out of analog voltage levels present on the backplane.
