Installing Cp Cables For Bits - Nortel 7400 Hardware Installation

Installing CP cables for BITS

Prerequisites
Procedure steps
Multiservice Switch 7400 Hardware Installation, Maintenance, and Upgrade 6.1S2
Install control processor (CP) building integrated timing supply (BITS)
cables between a CP-with-BITS and the BITS termination panel.
• Use the appropriate cable for your configuration. Refer to the
NN10600-170 Nortel Networks Multiservice Switch 7400 Hardware
Description for a list of cable part numbers and specifications.
• Ensure that you have routed and labeled the CP cable.
• The BITS termination panel provides the necessary terminations (DS1 or
E1 balanced, or E1 unbalanced) for the CP-with-BITS.
• Follow "Avoiding damage from static electricity" (page 208) to protect
the unit from damage by ESD or from transferring ESD to other
hardware.
CAUTION
Risk of equipment damage
To avoid damaging equipment, always connect the cable
to the termination panel before you connect it to the
control processor.
1 Set the dip switch on the BITS termination panel to "single cp" or "dual cp"
depending on whether you are connecting the termination panel to one
control processor or to two redundant control processors.
2 Connect the BITS cables to the output ports on the BITS termination
panel and tighten the screws. See the figure "Connections for CP-with-
BITS" (page 330)
3 Connect the other end of the cables to the DS1/E1 BITS ports on the
faceplates of the main and spare CPs. See the figure "Control processor
with BITS faceplate" (page 331)
