♦
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
Note
: When making cable or transceiver connections
to the MII inteface connector, make sure that
