Carel pCOWeb cards

[EcoStruxureIT]

Some devices, including many Uniflair cooling devices, use a network card from Carel called pCOWeb.  These cards can be problematic for Data Center Expert because the type of device they are installed in is not identified, and the same SNMP addresses (OIDs) are used to represent different things.

DCE cannot automatically choose the correct DDF for devices with pCOWeb network cards. If you only have one DDF installed to support devices that use the pCOWeb card, it's not a problem.

If you need multiple DDFs to support devices that use the pCOWeb card, you must configure the card to provide identifying information and modify the DDF to look for that information.

To configure the pCOWeb card:

Follow the instructions on page 35 of the pCOWeb User Manual to change the value of the system name at OID 1.3.6.1.2.1.1.5. The name should identify the DDF to use, for example, amico_leonardo_ug40mp40.

To modify the DDF:

1. Open the DDF in a text editor and find this line (note that the xxxxxx will vary between DDFs:

   <oidMustExist ruleid="xxxxxx" oid=".1.3.6.1.4.1.9839.2.1" istree="yes" />

2. Insert the following lines immediate after the line above, but replace xxxxxx with the name you created in the first step: 

             <oidMustMatch ruleid="sysname" oid=".1.3.6.1.2.1.1.5.0">
                    <valueList>
                            <value>xxxxxx</value>
                    </valueList>
             </oidMustMatch>
