Installing intramodule and intermodule cabling
Intermodule bus cable connection
card. In this case, the utility card on the last module acts as a
terminator. See the appropriate procedure for details.
CAUTION
Risk of equipment damage
External voice cables NT6P0111/8/9 and
NT6P0124/5/6 have high-density
connectors. You must install these
connectors very carefully to avoid damage
to the pins. Line up the connector at right
angles to the backplane, and press gently
until you hear a click. If you need to
remove the cables, use an extraction tool
(P0741489) and follow “Using the highdensity connector extraction tool” on
page 9-4.
Installing EVB
cabling—two
modules, one utility
card
You need one pair of EVB cables (NT6P0111/8/9 or
NT6P0124/5/6, depending on which length you need), and an
EVB terminator (NT6P0106). See “Intermodule cabling for a
three-module system” on page 9-15, diagram A.
Step Action
Installing EVB
cabling—two
modules, two utility
cards
Standard 1.0
1
Connect one end of an EVB cable from position 1 on shroud S7
of module MM0 to position 1 on shroud S5 of module MM1.
2
Connect one end of an EVB cable from position 0 on shroud S7
of module MM0 to position 0 on shroud S5 of module MM1.
3
Install the EVB terminator in positions 1 and 0 of shroud S7 of
module MM1.
Note: You do not need an EVB terminator in this configuration.
You need one pair of EVB cables (NT6P0111/8/9 or
NT6P0124/5/6, depending on which length you need). See
“Intermodule cabling for a two-module system” on page 9-13,
diagram B.
