Transit Protection-Important Notice
REMOVING THE TRANSIT TIE-WRAPS
When supplied the PCB card will be secured by 2 tie-wraps, looped around the card ejectors and through 2
holes in the base plate. Before installing the rack both of the tie-wraps should be removed by cutting off the
tie-wrap knot and completely removing the tie-wrap.
REPLACING THE TRANSIT TIE-WRAPS
Before shipping, the transit tie-wraps should be replaced with the
spare tie-wraps supplied (part no. RMW610). With the unit
free-standing ensure that the PCB card is pushed fully home
using the card ejectors. From the inside of the unit, feed the
tongue of the tie-wrap behind the card ejector and through the
base plate using the rear of the 2 holes. From the outside, feed
the tongue back through the base plate using the other hole, past
the front of the card ejector, feed through the eye of the tie-wrap,
pull tight and cut off the excess.
