The 3Com approved XENPAK transceivers are:

„

10GBASE-CX4 (3CXENPAK95)

„

10GBASE-ER (3CXENPAK96)

„

10GBASE-LR (3CXENPAK92)

To access the latest list of approved XENPAK transceivers 
for the Module on the 3Com Corporation World Wide 
Web site, enter this URL into your Internet browser:

When the Module is installed you can configure it 
through your Switch. Refer to the “Configuration 
Guide” and the “Command Reference Guide” supplied 
on the CD-ROM that accompanies your Switch for more 
information.

After you insert the XENPAK transceiver into the port, 
the Switch management software verifies the transceiver 
operation. If the transceiver is not working properly, the 
software displays one of the following error messages:

„

The XENPAK transceiver is invalid and will not be 
recognised by the Module.

To be recognised as valid, the XENPAK transceiver 
must conform to the XENPAK MSA.

„

The XENPAK transceiver is faulty and will not operate 
within the Module.

To correct these problems, completely remove the 
transceiver and then reinsert it. If the problem persists, 
contact 3Com Technical Support.

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 two 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.

„

Ensure 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.

„

If you are using non-3Com XENPAK transceivers, try 
using a 3Com XENPAK transceiver instead to test if 
the problem continues.

„

Ensure that you are using 24-28 AWG Infiniband 
copper cabling that is recommended on the 3Com 
web site (10GBASE-CX4 transceiver only):

For more general problem solving information, refer to 
the documentation supplied with your Switch.
