Infrastruxure AP76xx PDU only communicates with Data Center Expert or ISX Manager on the private LAN

Issue:
Infrastruxure AP76xx PDU only communicates with Data Center Expert or ISX Manager on the private LAN
 
Product Line:
StruxureWare Data Center Expert,
DCAL PDUs
 
Environment:
DCE ALL
PDU
3 Phase
DCAL communications protocol
 
Cause:
Older models of APC PDUs (usually AP76xx) can only be discovered using the private side of Data Center Expert (or ISX Manager) with DHCP enabled. They communicate through a custom protocol called DCAL.  You cannot set the IP of the device serially, and the device cannot be discovered on the public side of DCE / Manager
 
Resolution:
It is recommended to replace the PDU’s with more secure appliances for better communication and security.  Alternatively, the AP76xx must stay on the private side of a DCE server with DHCP settings enabled for monitoring.
