Cable routing for the power module board and power input board module

Follow instructions in this section to learn how to do cable routing for the power input board (PIB) module and power module board (PMB).

Attention

• For a smooth installation, connect the cables between the power module board and power input board module BEFORE installing the power module board.

• Depending on the specific configuration, the components in the node might be one of the following. The appearances are different but the procedure is almost the same.
  • DC PMB and DC PIB
  • Internal power supply (AC PMB) and AC PIB

Table 1. Cable routing for the DC PIB and DC PMB

Cable	From (Power module board)	To (Power input board)
1	LED connector	PMB status LED
2 & 3	Two power connectors Important When connecting these power cables, make sure to distinguish cables 2 and 3 and connect them correctly to their respective connectors. Switching these cables will cause failure.	Two power connectors

Cable	From (AC PMB)	To (AC PIB)
1	LED connector	PMB status LED
2	Power connector	Attached power cable

Procedure of installing the PMB-PIB cables

1. Make preparations for this task.

   • Install the power input board module with PMB status LED cable (see Install a power input board (PIB) module).

2. Depending on the configuration, connect and organize the two or three cables (1, 2, 3) for the power input board module and power module board.
   1. Connect the PMB status LED cable (1) to the power module board.
   2. Depending on the specific configuration, do one of the following.
      1. For configurations with DC PIB and PMB:
         1. Connect the power cables 2 and 3 to the two connectors on the PIB module and the two connectors on the PMB.
            Important

            • When connecting these power cables, make sure to distinguish cables 2 and 3 and connect them correctly to their respective connectors. Switching these cables will cause failure.

         2. Carefully twist and fold the power cables together.
         3. Carefully move the folded power cables toward the rear of node; then, place the folded cables under the rear edge of the node chassis.
      2. For configurations with AC PIB and PMB:
         1. Connect the power cable 2 from the PIB to the PMB connector.
   3. Place the LED cable toward the chassis sidewall as shown.
3. Install the power module board (see Install a power module board (PMB)).
