4. Identify the defective SBAR assembly from the amber LED on the assembly or

failure information at the HAFM server’s Hardware View.

5. The SBAR assembly is secured to the director backplane with two brass Allen

screws. Both screws cam the assembly into and out of the backplane. Disconnect

the SBAR assembly from the director 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 tip of the torque tool (1) into either brass Allen screw of the SBAR

assembly (2). Turn the screw one or two turns counterclockwise, as shown in

Figure 4–8.

6. Using the handle, pull the SBAR assembly out of the director chassis. Support the

assembly with one hand when performing this step.

7. Place the SBAR assembly in an antistatic bag to provide ESD protection.
