1-4 CHAPTER 1: WHAT IS THE LINKBUILDER MSH?
DUA1800-0AAA04
Available to order, but not shown on Figure 1-1:
The Cable Support Kit - Takes the weight of network cables and
prevents strain on the connections. See The Cable Support Tray
on page 1-10 and Appendix E for ordering information.
The MSH components are explained more fully in the sections
which follow.
The Chassis
The chassis has two versions. 3C18000 supports Ethernet and
Token Ring: 3C18001 supports FDDI as well. Upgrade from
3C18000 to 3C18001 is available. Ask your supplier for details.
Either chassis has eleven slots offering identical functionality to a
maximum of eleven modules if the unit is fully populated. Two
identical slots on the left-hand side of the chassis can each hold a
power supply unit (PSU). A power inlet panel loca ted between the
right-hand PSU slot (PSU 2) and the module slots provides two IEC
sockets, one for each PSU. It is worth noting at this point that
connectivity modules cannot be fitted into PSU slots, the PSU
cannot be fitted into module slots and the power in let panel
cannot be moved from its position.
The chassis is suitable for installation into a standard 19 inch rack
system or stand-alone desk or shelf mounting and has been
designed so that you may decide which face of the unit is the
front. Blanking plates of various sizes are supplied to cover any
unused slots whilst the unit is in operation.
Underneath the chassis there is a storage position for holding up
to four module user guides. We suggest that you use this as a
way of keeping the useful information contained in the guides at
your finger-tips.
Fitted in the chassis and central to the operation of the MSH is the
backplane.
