Solution 3: Building A Resilient Network - 3Com 3C16670 - LinkBuilder FMS II Hub Configuration Manual

Solution 3:
Building a Resilient Network
Requirements
Install a new structured cabling
system in a multi-floor build-
ing using a fiber backbone and
UTP floor wiring. The new
configuration replaces a thick
Ethernet backbone and thin
Ethernet floor wiring. New
hubs are needed in the wiring
closets on the floors and in a
data center. On some floors,
space considerations dictate
the use of compact, stackable
hubs. This network will run
mission-critical applications.

LinkBuilder Hub Configuration Guide
LinkBuilder MSH Configuration
Highlights
This solution uses LinkBuilder MSH
hubs and LinkBuilder FMS II stack-
able hubs in the wiring closets linked
to two central LANplex ® 6004
switches. The fiber optic backbone
also provides inherent resilience and
immunity from noise.
To protect the mission-critical
applications, each LinkBuilder MSH
hub has a connection to each of the
LANplex switching hubs. One con-
nection is designated the primary link,
while the other functions as a backup.
(Up to 16 Ethernet resilient link pairs
can be configured on a LinkBuilder
MSH hub.) The primary and second-
ary links are connected to separate

modules in the LinkBuilder MSH hubs
to protect the network against the fail-
ure of a single component.
The LinkBuilder MSH has other
resiliency features as well. Distributed
Repeater Architecture provides each
Ethernet module with its own repeater,
so a failure in one module cannot
bring down the others. And redundant
power supplies provide additional
protection. If one power supply fails,
the other takes over and an alert is
sent to the management station.
