I’ve sites with BTS 3012 AE Huawei and all of them have alarms related to DPMU, i ve send field technician to check this card but they said there isn’t!!
On site maintenance system and board management (M2000), this card is installed, configured and faulty with many alarms like smoke, humidity, DC over voltage…
So if someone could tell me the phisical place of DPMU on BTS3012 AE and give me more detail of this card.
Thanks in advance
