DS8000 Service Documentation Version 7.5

Routing the mainline power cables

Procedure

Uncoil the mainline power cables from the ship group.

The mainline power cable that connects to PPS-1 (upper) is longer than the mainline power cable that connects to PPS-2 (lower). 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

Ensure the 208VDC bus bar gate 4 is in the open position. Refer to Figure 1.
Route but DO NOT CONNECT the mainline power cables. Refer to Figure 1 to complete the following steps:
1. Route the longer mainline power cable up through the tailgate as shown and connect it to PPS-1 (upper).
2. Route the cable in between the 5/12V DDM "Y " power cables that connect the PPS-2 (lower) to the 5/12V bus bars as shown.
  Note: To make this easier, you can temporarily disconnect the right most connectors of the "Y" cables by removing the 4 screws 2 and moving the power cable 1 out of the way. The screws are not captive, so do not let them fall when they are removed.
3. Use one of the cable ties to fasten the upper cable to the bracket 3 .
4. Route the shorter mainline power cable up through the tailgate as shown and connect it to PPS-2 (lower).
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 mainline power cables to customer power until instructed to do so.
