Installing the Chassis
You can install the Switch 8800 in a standard, 19-inch rack or on a workbench.
Installing in a Standard 
Rack
When you are ready to install the Switch 8800 in the rack:
Carry the switch to the front of the rack. At least two people are required to move 
the switch.
Put the switch on the tray or the guides and push it into the rack.
Fix the switch in the rack with the combination screw and floating nuts that are 
shipped with the switch.
Installing on a 
Workbench
To install the switch on a workbench, take the following precautions: 
Ensure that the workbench is smooth and stable.
Leave a heat-dissipation clearance in the front and back of the switch of more 
than 1 m (3 ft) and at least 0.8 meters (2.5 ft) away from the walls on the sides.
Do not put heavy objects on the switch.
Installing the Cabling 
Rack
To install the cabling rack:
Attach the rack brace to the left side of the chassis (opposite the fan frame).
Insert the wiring channel into the brace and fasten the screws.
Installing a Module
To install a module:
Wear an antistatic wrist strap.
Remove the blank plate from the chassis slot and save it for future use.
Hold the ejector levers of the module with both hands and push them outward.
Align the module with the guides in the chassis and slide it gently into the slot.
Push the module until the captive thumb screw on its handle bar touches the hole 
in the chassis.
