IP Addresses
Whether or not the new system will receive dynamic IP addresses from a Dynamic
Host Configuration Protocol (DHCP) server, it is recommended that the IP addresses
be reconfigured as either:
•
Static IP Addresses
•
Dynamically Assigned IP Addresses
Static IP Addresses
To configure static IP addresses manually for each component you use values defined
for the site. If a DHCP server already exists on the dedicated service LAN, you must
configure the static IP addresses to be in the same subnet as the dynamic IP
addresses assigned by that 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)
Note. Be aware of possible conflicts with existing operations LANs. This guide cannot predict
all possible configurations of existing LANs. If the site where you install the maintenance switch
has network administrators and specialists, consult them for information about their current
Dynamic Host Configuration Protocol (DHCP) configuration.
