Follow the simple steps outlined in this section to install and start using

NOTE: Electrostatic discharge precautions should be taken when handling any
line card. Proper grounding is recommended (i.e., wear a wrist strap).
Unpack the Line Card
Your order has been provided with the safest possible packaging, but
shipping damage does occasionally occur. Inspect your line card

follow their instructions for damage and claims. Save the original
shipping carton if return or storage of the unit is necessary.
Set the Switches
MDI-II to MDI-X Switch (twisted-pair ports only)
To eliminate the need for crossover cables, the Radiance 10/100Mbps
interface line card includes an MDI-II to MDI-X switch on each
twisted-pair port. This push-in switch is located in the center of the
front panel and allows setup in either straight-through or crossover
configurations. The default setting is parallel (

).
When setting the switch, observe the positioning of the following
symbols:
•
The parallel symbol (
II
) indicates a straight-through or parallel
connection. The switch is up. (default)
•
The cross symbol (
X
) indicates a crossover connection. The
switch is down.
