Figure 31: S1 Switch Settings For The Pri Card - Mitel SX-200 EL Technician's Handbook

Technician's Handbook
The PRI card in slot 10 of the main control cabinet will appear to the
n
system as Bay 2. The PRI card in slot 11 of the main control cabinet
will appear to the system as Bay 4.
Because the system counts the PRI card as a peripheral bay,
the T1/E1 module on the PRI card does NOT occupy the
peripheral interface slots 5 and 6 in its residing cabinet.
The PRI card in a main control cabinet does not require a FIM II or
n
CIM because the PRI card connects directly to the backplane. You
can put a FIM II or CIM on the PRI card to connect the main control
cabinet to a peripheral cabinet. The interface module (FIM II or CIM)
on the PRI card in slot 10 would connect to Bay 3; in slot 11 would
connect to Bay 5.
Install a maximum of two PRI cards into a SX-200 EL peripheral
n
cabinet; slots 10 and 11.
The PRI card in a peripheral cabinet does require a FIM II or CIM to
n
connect to the main control cabinet. The system counts the PRI card
as a peripheral bay. The PRI card bay number corresponds to the
position that the FIM II or CIM terminates on with the Control FIM
Carrier card or the Control Triple CIM card.
A S1 switch on the PRI card controls where the source of the
clock and link signals come from (the backplane or the
interface module: FIM II or CIM).
Switch 1 closed and 2 open provides a backplane source.
Switch 1 and 2 closed provides an interface module source.
