3.3.2  
DIUN2 
 

Introduction  
The DIUN2 (Digital Interface Unit ISDN) provides 2 x 30 B channels (voice channels) for HiPath 3800. These are used
 •   for the S2M trunk connection (via NT).
 •   for S2M networking via S2M lines.
In HiPath 3000/5000 V5.0 and later, the B channels in the DIUN2 board are subject to license. Information on licensing can be found in Chapter 8 "Licensing".

The front of this board does not require an additional plate because EMC shielding has already been achieved by the front panel.

LED statuses and their meanings  

 Table 3-31   DIUN2 - LED Statuses
 Red LED  
 Green LED  
 Status  
 Action  
 Off  
 Off  
Board not receiving power or not plugged in correctly.  
Board is out of order.  
Check plug contact on board.  
 On  
 Off  
Board is receiving power and board test is in progress.  
Board is defective if status remains unchanged (board test unsuccessful).  
 
 
Replace the board.  
Loadware loading not successfully completed. Board is faulty.  
Replace the board.  
Error detected on board.  
Board is deactivated (not applicable to errors detected by test loops) or board was deactivated using HiPath 3000/5000 Manager E.  
Check whether the board was deactivated using HiPath 3000/5000 Manager E. If not, replace board.  
 Flashing  
 Off  
Loadware is being loaded.  
 
 Off  
 On  
Board test completed successfully. Board is OK (idle state).  
 
 Off  
 Flashing  
At least one channel is activated.  
 

Connection types  
 •   Fiber optic cable
The fiber optic cable is only connected via the front panel. The opto-electronic converter AMOM must be used to connect a fiber optic cable to the 15-pin Sub-D jacks on the front panel.
 •   Copper cable
The copper cable is only connected via the 15-pin Sub-D jacks on the front panel.
Notes:
 •   The connection type setting (fiber optic cable = DIUN2 mod., copper cable = DIUN2) is made in HiPath 3000/5000 Manager E: System Status - System-wide - Card Config. - Card Data. The connection type setting always applies to both interfaces (line 1 and line 2). Connection types "DIUN2 mod." and "DIUN2" cannot be used at the same time.
   -   Switch over to the connection type "DIUN2 mod." with an AMOM adapter plugged in and an existing fiber-optic connection: The fiber-optic path goes into operation immediately if configured correctly.
   -   Switch over to the connection type "DIUN2 mod." with an AMOM adapter plugged in and without an existing fiber-optic connection: The fiber-optic path goes into operation once the fiber-optic cable is plugged in if configured correctly. This can take up to three minutes.
   -   Switch over to the connection type "DIUN2 mod." without an AMOM adapter plugged in: If the connection type is switched before the adapter is plugged in, you must perform a Reload Card with HiPath 3000/5000 Manager E after plugging in the adapter to ensure that the adapter is detected by the DIUN2 board.
    The DIUN2 board automatically performs a reload after switching from "DIUN2 mod." to "DIUN2" or vice versa to load the loadware for the operating mode.
 •   Both interfaces can be operated with different versions of the AMOM adapter (see AMOM versions).
 •   Both interfaces can be operated with different protocols.
