Ports
Power Port
3-prong receptacle for 110V/60Hz or 220V/50Hz line (mains) power input.
100Base-FX Ports
One or two 100Base-FX ports. Each port operates at 100 Mbps, is fitted with a
fiberoptic SC or MT-RJ connector, transmits and receives on 1310 nm or 1550
nm carrier wavelength, and can be connected with a single-fiber singlemode
cable or dual-fiber singlemode cable or dual-fiber multimode cable. The power
budget available depends on the model as described in Appendix A: Models.
10/100Base-TX Ports
Two or four 10/100Base-TX ports. Each port has full auto-negotiation capability,
is fitted with an RJ45 UTP connector, and can be connected with a Category 5
cable up to 100 meters long. To use longer cables, consult your representative.
DIP Switch
12-toggle DIP switch for configuring the operation mode of 10/100Base-TX ports
individually. The toggles are divided into three groups marked
AUTO
,
10/100
,
and
FD/HD
.
AUTO
designates auto-negotiation,
10/100
designates 10/100 Mbps
data rate,
FD/HD
designates full-duplex/half-duplex. Each toggle marked with a
number (e.g.,
2
,
3
,
4
or
5
) is
functional
. The number designates the associated
port. Unmarked toggles are not functional and so their position may be ignored.
Table 1 specifies each DIP switch toggle, its two positions, and the function of
each position.
Note
To enable a
10/100
or
FD/HD
toggle to function, the
AUTO
toggle marked
with the same number must be set to the
DOWN
position
, i.e.,
auto-negotiation must be disabled
!
