Component Mounting Rules - Aastra 470 System Manual

Component mounting rules

The component mounting rules mentioned in the previous chapters are listed here
in an overview:
• The Call Manager card can only be fitted to slot 1.
• The application card can only be fitted to slot 2.
• Interface cards can be fitted to card slots 2 to 8.
Exception: If an application card is fitted, slot 2 is no longer available for interface
cards.
Tip: Leave slot 2 empty so that it can later be equipped with an applications card,
if required. This will save you a good deal of configuration work later on.
• For optimum heat dissipation interface cards should always be fitted to the basic
system in the same sequence as the slot numbering (from left to right, see
Fig. 25). The empty slots are therefore always those with the highest numbers
(with the exception possibly of slot 2).
• Two DSP modules can be stacked and are always fitted to the Call Manager card.
• IP Media modules are fitted to the Call Manager card or to PRI trunk cards and
cannot be stacked.
• The interfaces are enabled sequentially when the communication server is
started up. The following rules apply:
– The number of interfaces actually enabled is determined in each case by the
system capacity (see
the interface cards or all the interfaces of the last card may not be enabled.
– The interfaces are enabled in accordance with their designation, starting with
the lower designations. This means that the terminal interfaces on the proces-
sor card are always enabled before those on the interface cards.
