When the Module is installed you can configure it 
through your Switch. Refer to the SuperStack 3 Switch 
Implementation Guide and the Management Interface 
Reference Guide supplied with your Switch for more 
information.
When using the Module, note the following:
„
The ports only operate at 1000 Mbps.
„
The ports only operate in full duplex mode.
„
The Module is not hot-insertable.
„
The Module is not hot-swappable.
If you suspect a problem, carry out these steps before 
contacting your supplier:
„
Ensure that the Module is correctly installed in the 
Switch and that the three captive thumbscrews which 
secure the Module are tightened with a suitable tool.
„
Ensure that the Switch in which the Module is fitted 
is powered-up.
„
Ensure that the device at the far end of the link is 
powered-up and operating correctly.
„
Check that all connectors on the fiber optic segment 
are correctly engaged.
„
Clean the terminators by wiping them gently with a 
clean tissue or cotton bud moistened with a little 
ethanol. Dirty fiber terminators on the fiber optic 
segment impair the quality of the light transmitted 
through the cable.
