Installing the Fan
Assembly
The Switch 8800 is delivered with the fan assembly already installed. If you need
to replace a fan assembly, you can use the following procedure while the switch is
running.
1 Wear an antistatic wrist strap.
2 Remove the fan frame from the pack.
3 Hold the ejector levers on the fan frame with both hands and push them outward.
4 Align the fan with the guides in the chassis and slide it gently into the slot.
5 Push the fan until its positioning pin touches the hole in the chassis.
6 Push the ejector levers inward.
7 Push the handle bar pin into the hole in the chassis.
WARNING: To avoid injury, do not touch any naked wire, terminal, or any other
part of the product labelled Dangerous Voltage. Always wear the antistatic wrist
strap when installing the fan.
Installing Cables
This section describes how to connect console and AUX cables to the Switch
8800.
Connecting the Console
Cable
The console cable is an 8-core shielded cable. One end of the cable has a crimped
RJ-45 connector, which is plugged into the console port of the switch. The other
end has both a DB-9-hole connector and a DB-25-hole connector for connection
to a 9-hole or 25-hole serial port at the configuration terminal.
