AC Power Connector.
This is a three-pronged connector
that supports the power cord. Plug in the female connector
of the provided power cord into this connector, and the male
into a power outlet. Supported input voltages range from
100 ~ 240 VAC at 50 ~ 60 Hz.
♦
System Fan.
These fan are used to circulate air inside the
Switch and also to dissipate heat. The sides of the system
also provide heat vents to serve the same purpose. Do not
block these openings, and leave adequate space at the rear
and sides of the Switch for proper ventilation. Be reminded
that without proper heat dissipation and air circulation,
system components might overheat, which could lead to
system failure.
♦
MII Connector.
The MII (Media Independent Interface)
interface connector is a 40 pin connector for use with flexible
media (e.g. fiber cable).
This connector has a shared connection with port 2x, and
when connected, the MII connector takes operational
precedence over port 2x.
◊
If you are using a 100BASE-FX Transceiver, This
connector is used for connection between two
independent locations up to a distance of
two
kilometers
.
◊
If you are using a 100BASE-TX Transceiver, this
connector is used for connection between two
independent location up to a distance of
100 meters
.
When you are connecting a 100BASE-FX or TX Transceiver
to the MII connector prior to making cable connections,
make sure that the 100BASE-FX or TX Transceiver address
setting is set to “2,” (See the Transceiver manufacturer
user’s guide for more information). The pin specifications for
this connector appear in
Appendix C
