Routing the mainline power cables

Before you begin

Repeat the following steps for each rack that you are installing.

Procedure

  1. Uncoil the mainline power cables from the ship group.
  2. The mainline power cable that connects to PPS-1 (upper)  5  is longer than the mainline power cable that connects to PPS-2 (lower)  6 . See Figure 1. Use the cable label and part number (P/N) to identify the longer cable.
    Table 1. Cable label and part number
    Feature Code P/N of shorter cable P/N of longer cable
    1090 - 3 phase 60A non EMEA 22R1190 22R2222
    1091 - 3 phase 60A EMEA 22R3794 22R3795
    1092 - 3 phase 60A Japan 22R1191 22R2224
    1093 - 3 phase 60A Chicago 22R1188 22R1189
    1060 - 1 phase non EMEA 17P9592 17P9593
    1065 - 1 phase Chicago 17P9590 17P9591
    1067 - 1 phase EMEA 17P9595 17P9596
    CAUTION:
    Do not connect the storage facility mainline power cables to customer power until instructed to do so.

  3. Ensure the 208VDC bus bar gate  4  is in the open position. See Figure 1.
  4. Route and connect the mainline power cables to Rack-1 and any expansion racks.
    Note: For this task, you have the option of disconnecting the 5/12V DDM "Y" power cables. See Figure 2. The four screws  2  that secure these cables to the PPSs are not captive, so do not let them fall when you remove them.
    1. Route the longer mainline power cable  3  up through the tailgate and behind the 5/12V DDM "Y" power cables  1 . See Figure 2. To make this easier, you can temporarily disconnect the right-most connector of each "Y" power cable.
    2. Connect the mainline power cable to PPS-1 (upper). Use one of the cable ties  3  to fasten the upper cable to the bracket.
    3. Route the shorter cable  2  up through the tailgate. Connect it to PPS-2 (lower) similarly to what is shown in Figure 1.
    Notes:
    • If this is on a raised floor, route the cables down through the floor cutout and near the customer power connectors.
    • If this is not on a raised floor, route the cables underneath the frame behind the rear caster so they exit to the side. The cables must not exit the rack in the front or rear service areas.
    CAUTION:
    Do not connect the storage facility mainline power cables to customer power until instructed to do so.
