7. The UPM card is secured to the director chassis with two captive Allen

screws. The bottom screw is spring-loaded and locks the UPM card in place.

The top screw cams the UPM card into and out of the backplane.

Caution: The torque tool supplied with the Director 2/64 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 HP product. Use of the wrong tool may overtighten and damage logic

cards.

a. Insert the torque tool into the locking Allen screw at the bottom of the

card. Turn the screw counterclockwise until the spring releases and the

tool turns freely.

b. Insert the torque tool(1) into the cam Allen screw at the top of the card

(2). To unseat the UPM card and cam it out of the backplane, turn the

screw counterclockwise until the tool turns freely, as shown in Figure 75.

8. Pull the UPM card from its card track and remove it from the director chassis.

Place the card in an antistatic bag to provide ESD protection.
