8237 Hub Installation and Planning Guide
Installing an Expansion Port
The types of Expansion Port are illustrated in Figure 4-5 on page 4-8. If you are
installing an optional Expansion Port, use the instructions that follow. If you are not
installing this feature, continue with "Installing and Routing Cables."
Note: The Expansion Port is not hot-pluggable.
The Expansion Port slot is located at the lower left of the front of the 8237. See
Figure 1-1 on page 1-1 for its location.
1
Remove the Expansion Port slot cover-plate by turning the two knurled
knobs on the front counterclockwise. Retain the cover-plate so that you can
locate it in the future, should you need to replace it in the 8237. If an
Expansion Port is removed from the 8237, you should always replace the
cover-plate to ensure proper cooling.
2
Insert the Expansion Port, ensuring that the edges slide through the guides,
until the connector end is firmly seated.
3
Push and turn the two knurled knobs clockwise until they are securely
attached to the 8237 frame.
Installing and Routing Cables
Remember these tips when connecting cables:
Avoid stretching or bending cables.
Avoid routing cables near potential sources of electromagnetic interference, such as
motorized devices or fluorescent lights.
Route cables away from aisles and walkways to avoid creating trip hazards. Use
floor cable covers to secure cables if such routes cannot be avoided.
Connecting Cables to 10BASE-T Ports and Expansion Ports
1
Refer to your network documentation to determine each cable’s port or
Expansion Port assignment.
2
Using appropriate connectors, connect the cables to the ports or Expansion
Ports.
3
Label the cables so that it will be easy to identify the device at the other end
of the cable if you have to troubleshoot a network problem. At the end of the
cable nearest the 8237, place a label containing a unique identifier for the
cable, the location and MAC address of the device at the other end of the
cable, and the number of the port to which the device is attached.
4
If required, at the attached device’s end of each cable, connect a cable from
the device to any faceplate or other intermediate connection point, as
appropriate.
