Page 14: Chapter 3: Additional Pdu Information
Chapter 3: Additional PDU Information Reserving IP Addresses in DHCP Servers The PDU uses its serial number as the client identifier in the DHCP request. Therefore, to successfully reserve an IP address for the PDU in a DHCP server, use the PDU's serial number as the unique ID instead of the MAC address. Since all network interfaces of the PDU can be simultaneously enabled and configured with diverse static IP addresses, the client identifier of each network interface is different.
