2.1.1 Damaged Pins
The pins used in the back plane connector should not be straightened after they have been
deflected more than 10 degrees from vertical as they will “work harden” and break at the
bend. Bent pins must be removed and replaced using special tools and is not
recommended as a field repair. Remove shelf with damaged pins and contact ADC for
replacement. Refer to 8. Customer Information and Assistance.
