Installing System Boards
7.1
Chassis Board Configuration
Boards must be installed in their designated slot to enable their full functionality. All boards
are hot swappable and therefore can be inserted and extracted without turning off electrical
power on the 4700 chassis.
The 4700 chassis is factory pre-assembled with fan units. Additional boards and modules are
shipped according to the system configuration and are added during installation. Refer to
System Configurations

Inserting/Extracting Boards
Fabric boards, management boards, and line boards have ejectors that lock the board in place
and serve as levers for seating or extracting.
The ejectors snap inward to lock the board in place.
Two screws on each board complete the seating and lock of the board in place.
The following figures illustrate the ejectors action (the photos below are of the previous
design; the new design has black plastic covers).
(on page 18) for a list of the possible chassis configurations.
Every slot that is not populated with a module must be covered with a blank panel for
proper cooling.
When handling electronic boards, wear grounding wrist straps to avoid ESD damage to
the card. Do not touch the Midplane with your hand or any metal tool, or you could shock
yourself.
