Removal

step 3 . If the director is rack-mounted, perform one of the
following:
— If the director is installed in an equipment cabinet, insert the
5/16" door tool into the socket hole at the right top of the rear
door. Turn the tool counter-clockwise to unlock and open the
door.
— If the director is installed in a customer-supplied equipment
cabinet, unlock and open the cabinet rear door as directed by
the customer representative.
2. Remove the RFI shield.
ATTENTION! To avoid causing machine errors or damage while working on
the director, follow ESD procedures by connecting a grounding cable to the
director chassis and wearing an ESD wrist strap.
3. Follow ESD procedures by attaching a wrist strap to the director
chassis and your wrist ( Figure 69 ).
4. Identify the defective SBAR assembly from the amber LED on the
assembly or failure information at the management server
Hardware View.

handles (extractor levers) that snap lock ( Figure 78 ). Open both
handles.
