6 Installing Field-Replaceable Units in the ISR 9XXX Chassis
The ISR 9288 chassis is pre-assembled with the fan units (sFU-4 and sFU-8) and the rear panel
sCTRL board. You must install all boards in their designated slot to enable their full functionality.
All boards are hot swap enabled (for some boards, only when the hot swap indicator LED is
illuminated) and you can insert and extract these boards without turning off electrical power.
Additional boards and modules might be shipped according to the system configuration and
are assembled during installation. Alternatively, you might be swapping out a chassis only, and
repopulating the new chassis with modules from and existing, defective, chassis. Every slot that
is not populated with a module must be covered with a filler panel for proper cooling. The
following FRU components are described:

6.1 Guidelines for Inserting and Extracting Boards
Observe the following precautions when inserting and extracting boards.
•
Wear grounding wrist straps to avoid ESD damage.
•
To avoid risk of electric shock, do not touch the backplane with your hand or any metal tool.
•
Line, sFB-12, sMB, and other ISR 9288 boards have a pair of ejectors that lock the board in
place and serve as a lever for seating or extracting. The ejectors snap inward to lock the
board into place.
•
Before starting to extract a board, press the red button to disengage the lock. This button
signals the extraction request to the interconnect.
•
Each ejector has a guide pin that slides into a groove in the chassis. If the guide pin is not
perfectly aligned with this groove, you might experience difficulty in locking the ejector
handles in place. Should this occur, manipulate the ejector handle gently until it locks into
place
•
Insert screws manually at first to ensure that the screw engages directly on the thread and
does not cross-thread. Tighten the screws with a screwdriver in the following sequence:
1.
Top right.
2.
Bottom left.
3.
Top left.
4.
Bottom right.
•
If you use a powered screwdriver, do not use a higher torque setting than 3. Settings higher
than 3 might damage the screws.
