Terminal identification is provided by Figure 32. On
the drawing, the six terminal pairs are labeled WlOO
through W105. The top three terminal pairs (WlOl,
W103 and W105) are used to connect the LO terminals
of the banks together. The bottom terminal pairs
(WlOO, WI02 and W104) are used to connect the HI ter-
minals of the banks together. Table 3-1 summarizes the
effects of each jumper.

Referring to Figure 3-l for jumper locations, perform
the following steps to install bank-to-bank jumpers:
1. If mated together, separate the relay card from the
comector card by removing the mounting screw
and pulling the two cards away from each other.
Remember to only handle the cards by the edges
and shields to avoid contamination.
2. Refer to Figure 32 and Table 31 to determine
which jumpers to install.
3.
Using Figure 3-3 as a guide, install the jumpers on
the appropriate terminal pairs.

3.3.2 Backplane jumpers
The Model 7001 mainframe has an analog backplane
that allows the banks of a Model 7011 multiplexer to be
internally connected to a compatible
switching
card in-
stalled in the other slot (see paragraph 2.4.1 for details).
The backplane jumpers for the multiplexer card
assembly are located on the relay card as shown in
Figure 3-4. The card is shipped from the factory with
the jumpers installed.
Jumper removal
Perform the following steps to remove backplane
jumpers:
1. If mated together, separate the relay card from the
connector card by removing the mounting screw
and pulling the two cards away from each other.
Remember to only handle the cards by the edges
and shields to avoid contamination.
2. Use Figure 3-4 to locate the jumper(s) that are to be
removed.
3. It is not necessary to physically remove the jump-
ers from the PC board. Using a pair of wire cutters,
cut one lead of each jumper.
