390 NT6D80 MSDL card
Though the MSDL is designed to coexist with other cards, the number of
ports supported by a system equipped with MSDL cards is potentially four
times greater than when using other cards. Since each MSDL has four
ports, representing a single device, a system can support as many as 16
MSDL cards with a maximum of 64 ports.
Physical description
The MSDL card is a standard size circuit card that occupies one network
card slot and plugs into the module’s backplane connector to interface with
the CPU bus and to connect to the module’s powersupply. On the faceplate,
the MSDL provides five connectors, four to connect to I/Ooperations
and one to connect to a monitor device that monitors MSDL functions.
Figure 101 "MSDL component layout" (page 390) illustrates major MSDL
components and their locations on the printed circuit card.
Note: Switches S9 and S10 are configured to reflect the device number
set in LD 17 (DNUM). S10 designates tens, and S9 designates ones.
For example,set device number 14 with S10 at 1 and S9 at 4.
