Ethernet only - two path wiring scenario
This “Ethernet only” wiring scenario is also intended for enterprises who currently
have Ethernet wiring and do not want Token Ring wiring introduced into their
environment. The two path scenario is included to provide the possibility of a
second, separate and redundant path to the support Elements.
The Ethernet features assume the use of 10/100 Mbit Ethernet facilities, requiring
the use of CAT-5 Ethernet cabling. Since the Support Element Ethernet only
feature includes two Ethernet adapters, there will be two Ethernet connections
available. For this scenario, both the Ethernet cables will be used.
The TCP/IP protocol used in Support Element to Hardware Management Console
communication is defined for both adapters in the PCMCIA slots of the support
Elements.
It will be necessary to connect the “top” Ethernet adapter cable to a customer
supplied local hub capable of 10/100 Mbit Ethernet rates. It will be necessary to
connect the Ethernet from at least one local Hardware Management Console to
the same hub as the support Elements.
It will be necessary to connect the “bottom” Ethernet adapter cable to a customer
supplied local hub capable of 10/100 Mbit Ethernet rates. This second adapter
will have to be assigned an address on a separate subnet from the first adapter.
Any Hardware Management Consoles attached to either LAN will be able to
automatically discover the support Elements, assuming that the LAN network
allows Multicast packets to flow and that the support Elements are on the same
TCP/IP subnet(s) as the Hardware Management Consoles.
