Factory Reset

Sometimes the need arises to reset a PXSe unit to factory conditions, e.g. a unit was in the field, its IP parameters were changed and are not known, so there's no access to rerconfigure or debug it.

PXSe units starting with S/N 65676 have a Factory Reset facility that is activated by the following procedure:

• Short pins 25 and 15 of the DB25 straight connector (P/N CBL-PXSe-H-25-1)
• Connect the cable to the PXSe first synchronous line connector (lower right)
• Power-cycle the PXSe

Once the avobe procedure is completed, the PXSe is set to "Factory Defaults":

There are two very important things to note here:

• The default application is set to hdlcsrv
• The Boot Timeout parameter is set to 0, which means that the PXSe ramains in RedBoot and the default application is not started.

It will be necessary to access the RedBoot prompt and change these two parameters to the appropriate value, i.e., the default application to the corresponding one (e.g. synctunnel) and the timeout value to probably 15 seconds (this is what we typically use).

In addition, the IP parameters will have to be set to the appropriate parameters according to the network where the PXSe is installed.
