The LinkBuilder MSH
The LinkBuilder MSH provides a central hub for network
interconnection and management.
There is a diagram of an MSH and key to the compnents overleaf.
The basis of the MSH is the chassis, into which can be installed a
series of media specific modules. At the heart of the chassis is the
backplane onto which all modules connect. It is the backplane
which allows communication between the network segments
using the MSH. A locking bar fitted across the front of the MSH
chassis prevents removal of modules and power supply units by
unqualified personnel.
