Figure 4-1Connections of the power cables and PGND cables
NOTE
The PGND cables of the cabinet should be connected to the nearest ground bar. When the PDF is far away
from the cabinet, for example, the PDF is not in the same equipment room as the cabinet, you should
connect the PGND cable for the cabinet to the nearest ground bar co-grounded with the PDF rather than
connect the PGND cable directly to the PDF. In this case, the methods of installing and routing the PGND
cables are the same as those of connecting the PGND cables directly to the PDF. In practice, the PGND
cables of the cabinet must be connected on the basis of the requirements of the customer.
4.3 Principles of Installing the Power Cables and PGNDCables
This section describes the principles of installing the power cables and PGND cables. When
installing the power cables and PGND cables, you should follow the routing and binding
principles.
Cable Routing Requirements
l The layout of power cables and PGND cables should facilitate future capacity expansion.
l The power cables and PGND cables must be separated from the other cables. When the
power cables and the PGND cables are laid parallel to signal cables, the spacing between
them must be at least 30 mm.
l Ensure that the bending radius is five times longer than the diameter of the cable.
l In underfloor cabling mode, a surplus length of power cable must be reserved outside the
cable inlet of the power distribution box on the top of the cabinet. This facilitates the
installation of the terminal. In addition, the cables must be laid flat on the top of the cabinet.
l When connecting power cables to the terminals of the power distribution box, lay the cables
straight and smoothly.

l The subracks, fan boxes, and boards are installed in the cabinet.
l The required tool (multimeter) is available.
Context
The cabinet uses the DC power supply. Technical Specifications of the Power Distribution Box
lists the specifications for the input power of the cabinet.
CAUTION
Wear the ESD wrist strap correctly. Ensure that the ESD wrist strap is properly connected to the
ESD connector on the cabinet.
Before powering on a subrack, do not insert a board into or remove a board from the subrack to
avoid static damage to boards.
Procedure
Step 1 Set the corresponding output switches on the PDF to OFF and set all the output switches on thepower distribution box of the cabinet to OFF.
Step 2 Set the multimeter to the resistance scale, and then measure the resistance at the power outputterminal for the PDF and at the input and output terminals for the power distribution box of the
cabinet. Ensure that there is no short-circuit either between the -48 V working power and the
RTN working ground or between the -48 V working power and the PGND protection ground.
Step 3 Set the corresponding output switches on the PDF to ON and all the output switches on the powerdistribution box of the cabinet to OFF.
Then, the power distribution box enters the self-check state. (The RUN and ALM LEDs on the
power distribution box are ON at the same time and the buzzer sounds.) When the self-check is
complete, the power distribution box requests for registration at the SCUa board (the RUN LED
on the power distribution box blinks at 2 Hz) until the registration is successful (the RUN LED
blinks at 0.5 Hz). For the description about the status of LEDs on the power distribution box,
see LEDs on the PAMU Board.
Step 4 Set the multimeter to the voltage scale. Ensure that the PDF output voltage and input voltage ofthe power distribution box ranges from -40 V to -57 V.
Step 5 Set the corresponding two switches on the power distribution box to ON on the basis of subrack.
Step 6 Set the multimeter to the voltage scale. Use the multimeter to check whether the output powerof each power distribution box ranges from -40 V to -57 V. Check whether the fan box in the
subrack can be normally started and whether the power supply to the boards in the subrack is
normal.
l Normally, when the subrack is powered on, the STATUS LED is green on the panel of the
fan box blinks. In case of exceptions, immediately turn off the switches of the power
distribution box and PDF. Check whether the output voltage of the power distribution box
is normal and whether the power cables are installed properly. For the description about the
status of LEDs on the fan box, see Fan Box.
l
Normally, when the subrack is powered on, the RUN LED on the panel of the board is ONor blinks. If all the LEDs on a board are OFF, the board or the corresponding slot may be

7 Reserved, generally set to ON.
8 (the most significant bit) Reserved
As the DIP switch uses odd parity check, the number of 1s in the eight DIP bits must be an odd
number. The setting should adhere to the following principles:
1. Set DIP bits 1 to 5 as required.
2. Set DIP bit 7 to 0.
3. Note that the setting of bit 8 remains unchanged.
4. Count the number of 1s in the seven bits of the DIP switch.
l If the number of 1s is even, set DIP bit 6 to 1.
l If the number of 1s is odd, set DIP bit 6 to 0.
Assume that the subracks are numbered from 0 to 2 and that bit 8 is set to OFF. For the setting
of the DIP switch in this case, see Table 5-2.
