DS8000 Service Documentation Version 6.3.3

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. Was the rack ordered with a top exit line cord feature?
    • Yes, go to step 7.
    • No, go to step 3.
  3. The mainline power cable that connects to PPS-1 (upper) Callout label 5 is longer than the mainline power cable that connects to PPS-2 (lower) Callout label 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.

  4. Ensure the PDUs  4  are in the open position. See Figure 1.
  5. Route and connect the mainline power cables to Rack-1 and any expansion racks. See Figure 1.
    1. Route the longer mainline power cable Callout label 1 up through the tailgate, behind the PPS 208V power module cables as shown (see Figure 2 Callout label 7 ) and connect it to PPS-1 (upper) Callout label 5.
    2. Use one of the cable ties Callout label 3 to fasten it to the bracket Callout label 3.
    3. Route the shorter mainline power cable Callout label 2 up through the tailgate as shown and connect it to PPS-2 (lower) Callout label 6.
    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.

  6. Go to Determining mainline power cable type (plug in or wired).
  7. For the top exit line cord features, the mainline power cable that connects to PPS-2 (lower) Callout label 6 is longer than the mainline power cable that connects to PPS-1 (upper) Callout label 5. See Figure 4. Use the cable label and part number (P/N) to identify the longer cable.

    1095 - 3-phase 60A Japan/non-EMEA (RS) 99Y1177 99Y1176
    1096 - 3-phase 40A EMEA 99Y1174 99Y1173
    1097 - 3-phase 30A Japan (IEC 309) 99Y1186 99Y1185
    1070 - 1-phase 60A Japan/non-EMEA (IEC 309) 99Y1180 99Y1179
    1071 - 1-phase 40A EMEA 99Y1183 99Y1182
    CAUTION:
    Do not connect the storage facility mainline power cables to customer power until instructed to do so.

  8. Ensure the PDUs Callout label 4 are in the open position. See Figure 4
  9. Remove the top exit cover plate.
    1. Remove the four screws securing the cover plate to the top of the rack. Remove the cover plate. See Figure 3.
    2. Reinstall the screw Callout label 1 nearest the rear of the rack. See Figure 3. Save the remaining screws to install the clamp housing.
    3. Store the cover plate in the document enclosure.
  10. Route and connect the mainline power cables to Rack-1 and any expansion racks. See Figure 4.
    1. Route the longer mainline power cable Callout label 2 down through the opening, behind the PPS 208V power module cables as shown (see Figure 2 Callout label 7) and connect it to PPS-2 (lower) Callout label 6.
    2. Use one of the cable ties to fasten it to the bracket .
    3. Route the shorter mainline power cable Callout label 1 down through the opening as shown and connect it to PPS-1 (upper) Callout label 5.
      CAUTION:
      Do not connect the storage facility mainline power cables to customer power until instructed to do so.
  11. Remove the adjustable clamp bracket Callout label 2 from the top exit line cord clamp housing Callout label 1. Position the housing around the power cables and secure to rack using the three screws from step 9b, above. Install the adjustable clamp bracket into the housing, but do not tighten at this time. See Figure 5.
