214 SAN140M Installation and Service Manual
5. The CTP card is secured to the director chassis with two captive
Allen screws. The bottom screw is spring-loaded and locks the
CTP card in place. The top screw cams the CTP card into and out
of the backplane.
ATTENTION! The torque tool supplied with the director is designed to
tighten director logic cards and is set to release at a torque value of six
inch-pounds. Do not use an Allen wrench or torque tool designed for use
with another IBM product. Use of the wrong tool may overtighten and
damage logic cards.
6. Insert the torque tool into the locking Allen screw at the bottom of
the card. Turn the screw counter-clockwise until the spring
releases and the tool turns freely.
7. Insert the torque tool into the cam Allen screw at the top of the
card (Figure 70). To unseat the CTP card and cam it out of the
backplane, turn the screw counterclockwise until the tool turns
freely.
8. Pull the CTP card from its card track and remove it from the
director chassis. Place the card in an anti-static bag to provide
ESD protection.
