IP Addresses
Static IP Addresses
Static IP addresses have to be configured manually for each component. If a DHCP
server already exists on the dedicated service LAN:
•
Configure the static IP addresses to be in the same subnet as the dynamic IP
addresses assigned by that server.
•
If IOMF 2 CRUs are connected to the LAN, the static addresses for IOMF 2 CRUs
must be in the same range as each other and as the DHCP server. However, these
addresses cannot be in the range of addresses managed by the DHCP server.
Dynamically Assigned IP Addresses
Dynamically assigned IP addresses are provided by a DHCP server that assigns an IP
address whenever a component is added or moved.
If a DHCP server is already present on the network to which these components will be
connected, you can use that server. If your network is not equipped with a DHCP
server, work with your account team to identify available options.
Some guidelines for configuring the DHCP server:
•
Configure the range of IP addresses to be assigned dynamically by the DHCP
server to be in the same subnet as existing IP addresses on the LAN and any
static IP address included in the dedicated service LAN.
•
IP addresses for these components should remain static:
°
The four IP addresses reserved for the OSM Low-Level Link and Service
Connection
Do not include these address in the pool of addresses the DHCP uses for
address assignment.
°
The UPS (recommended but not required)
Static or Dynamic IP Addresses
Various components within the dedicated service LAN can have static or dynamic IP
addresses. This sample shows the address in an example dedicated service LAN;
however, any combination is possible:

them)*
