The Modules
The range of modules available for installation into the
LinkBuilder MSH is constantly being extended. Please contact your
local supplier for further information.
If you already have a LinkBuilder ECS10 or ECS4, the modules
that you use for this system can be easily adapted for installation
into the MSH chassis. This is achieved by attaching a converter to
the ECS module which will allow it to connect to the MSH
backplane.
ECS modules are also known as line cards.
You will find further information about module functionality in
Chapter 3,
LinkBuilder MSH Modules
on page 3-17 in this user
guide.
Power Supply Units (PSU)
Two slots are provided within the MSH chassis for power supply
units. The MSH can be configured with one PSU installed into
the chassis. However with two PSUs installed, each contributes
approximately half of the power requirement, enabling the load
to be shared. This increases the reliability of the power supply
units. Failure of one of the power supply units would result in the
other unit taking over the full load, without any interruption to
the operation of the MSH.
See Appendix C for details of the use of the two different capacity
PSUs and how to calculate power requirements for a particular
MSH configuration.
