C.2 Connection Configurations of the 5500 Control Unit
The IBM 5500 Express IP controller can be part of your network in a number
of different configurations. Five typical network layouts are shown in this
section.
Although typical applications of the 5500 control unit, these examples are just
a few of the many ways you can exploit the unique features and
characteristics of this controller.
IBM recommends that, when using the 2Mbps Mode, install your Express
devices on a different port than your legacy devices. Also, ensure that you
have Express-enabled hubs and multiplexers (IBM 7299). IBM 5500 in an
Express environment.
The 5500 Control Unit is not a router or a DHCP relay agent. Therefore,
5500 twinax clients cannot make DHCP requests unless there is a DHCP
server on the twinax segment, or a DHCP Server on a 5500 LAN segment
and the twinax subnet is configured as part of that LAN. Clients on the
second 5500 LAN segment cannot communicate with the DHCP server on
the first LAN. For DHCP requests to travel across a WAN, a LAN-based
router must be installed with a relay agent.
