Card Installation Rules
The NV5128 was designed to make installation and expansion easy to perform. Some cards, such
as the control card and analog input card or analog output card, have jumpers or switches for
options. It is recommended that all jumpers and switches be set before placing the router into ser-
vice. (See
Configuration Tasks to Perform Before Installing Cards on page 47.)
There are some restrictions as to which slots cards can be installed in the NV5128 frame. Slots 11,
12, 13 and 14 are unique. (See Figure 2-3 on page 11.) These slots have inter-slot connectors that
allow signals to be passed between cards installed in these slots. This communication is necessary
for proper functioning of the Classic SWB card set and the Machine Control card set. The proceed-
ing sections outline card and card set installation rules.
Rules for Partitions and Card Installation
When installing or reconfiguring input cards and output cards in the router frame, it is important to
keep in mind how partitions for the router control system are created. Some third-party control sys-
tems require contiguous partitions, that is, that signal types are grouped together and placed in spe-
cific sequence in the router frame.
If using an NV9000 router control system partitions do not need to be contiguous. Using the “vir-
tual level” feature in the NV9000, signal types can be organized into different levels, no matter
where the active cards are installed in the frame. For more information, see the NV9000 User’s
Guide.
If using a third-party router control system, active cards should be installed such that physical parti-
tions are contiguous. This helps ensure maximum compatibility. If you are unsure about future
router control system applications, configuring the frame with contiguous physical partitions is the
best choice.
Rules for Standard SWB Cards
Standard SWB input cards (EM0466) may be installed in any input slot in the frame. There are two
types of Standard SWB output cards: main (EM0463) and expansion (EM0465). The main output
card occupies four slots in the router frame: one for the main output card with a “wing” and three
slots for optional expansion cards that mate with the wing on the main card. For more information
on card functions, see
Standard SWB on page 28.
When installing four or fewer standard SWB input cards, it is recommended that the cards be
installed in the right-hand input slots in the frame, beginning with slot 12 and working backwards.
This leaves room for installation of the standard SWB output cards. If your switching configuration
requires 64 SWB outputs or fewer, install the standard SWB main output card (EM0463) in slot 13.
Use slots 14, 15, and 16 for additional standard SWB expansion output cards (EM0465). If more
