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:
Ethernet Cables
Ethernet connections for a dedicated service LAN require Category 5 unshielded
twisted pair cables.
SWAN Concentrator Restriction
•
Isolate the dedicated service LAN from any ServerNet wide area network (SWAN)
on a system.
•
Isolate redundantly configured SWAN concentrator subnets from the dedicated
service LAN.
•
Do not connect SWANs on a subnet containing a DHCP.
