7 Operating
behavior
7.1 Power
supply
The NMI can be supplied by PoE (Power over Ethernet) from a switch. The PoE per-
formance class is class 2.
As an alternative to the PoE switch, a PoE injector or midspan can be used.
The two PoE supply variants, phantom power and spare-pair power, are supported.
7.2 DHCP
In the operation mode unicast, the NMI tries to obtain the network configuration from a
DHCP server in the network. The DHCP options are automatically evaluated.
The precise description can be found in the manual BE-800793 Description MOBA-
Time network clocks.
It is the task of the network administrator to configure the DHCP options accordingly.
7.3 IPv6
IPv6 allows for up to 4 parallel IP addresses, prioritized in decreasing order:
-address given by DHCPv6
-fix address
-address calculated with auto-config (SLAAC / RA)
-link local address
It is possible to deactivate DHCPv6 and / or auto-configuration.
Calculation of the link local address from the MAC address:
fe80::2[2nd part MAC]:[3rd part MAC]ff:fe[4th part MAC]:[5th part MAC][6th part MAC]
Example:
MAC: 00:16:91:12:34:56
IPV6:
fe80::216:91ff:fe12:3456
7.4 DHCPv6
In the unicast operating mode, the NPR tries to get the network configuration from a
DHCPv6 server in the IPv6 network. The DHCP options are automatically evaluated.

network clocks.
The network administrator is responsible for configuring the DHCP options accordingly.
7.5 Autokonfiguration
/
SLAAC
In the unicast operating mode, the NPR tries to calculate the network configuration
from the information of a router (RA) in the IPv6 network: IPv6 address.
