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:
1 Carry the switch to the front of the rack. At least two people are required to move
the switch.
2 Put the switch on the tray or the guides and push it into the rack.
3 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:
1 Attach the rack brace to the left side of the chassis (opposite the fan frame).
2 Insert the wiring channel into the brace and fasten the screws.
Installing a Module
To install a module:
1 Wear an antistatic wrist strap.
2 Remove the blank plate from the chassis slot and save it for future use.
3 Hold the ejector levers of the module with both hands and push them outward.
4 Align the module with the guides in the chassis and slide it gently into the slot.
5 Push the module until the captive thumb screw on its handle bar touches the hole
in the chassis.
