❑
The fiber optic port can be set to half- or full-duplex. If you are
connecting the fiber port to a companion bridging converter (i.e., AT-
FS238a/1 to AT-FS238b/1 or AT-FS238a/2 to AT-FS238b/2), you
should leave the duplex setting at the default setting of full-duplex for
best performance. If you are connecting the fiber optic port on the
bridging converter to an IEEE 802.3ah-compliant device, you must
determine the duplex mode of the compliant device and set the duplex
mode of the fiber optic port on the bridging converter accordingly.
4. If you are installing the bridging converter in an AT-MCR12 chassis,
download the AT-MCR12 Chassis Installation Guide from our web site for
instructions on how to install the bridging converter in the chassis, then
proceed to Step 7.
Note
A 12-50VDC bridging converter cannot be installed in an AT-MCR12
chassis.
5. Place the bridging converter on a secure, level surface, leaving ample
space around the bridging converter for ventilation.
6. Apply power to the bridging converter.
For instructions on how to apply power to a 12VDC version AT-FS238a/x
or AT-FS238b/x Series Bridging Converter, refer to “Connecting a 12VDC
Powered Unit” on page 27.
For instructions on how to apply power to a 12-50VDC version AT-
FS238a/x or AT-FS238b/x Series Bridging Converter, refer to “Wiring and
Connecting a 12-50VDC Powered Unit” on page 28.
Note
This step does not apply if you are mounting a 12VDC-version bridging
converter in an AT-MCR12 chassis.
7. Remove the dust cover from the fiber optic port and connect the fiber optic
cable to the 100Base-FX port.
When attaching a fiber optic cable, be sure to observe the following
guidelines:
❑
You should verify that you are using the appropriate type of fiber optic
cabling. Refer to Table 4 on page 21 for fiber optic cabling
specifications.
