Routing and connecting the rack power control cables to the RPC cards

Procedure

  1. You will perform the following steps for one expansion rack at a time, starting with Rack-2. If you have Rack-3 or Rack-4 to install, you will be sent back here later.
  2. At the rear of the expansion rack being installed, find the power control cable that connects to the upper and lower DC-UPS connector E1-J6. See Figure 1. The loose end of the cable has a gray label.

  3. Route the J6 expansion rack power control cables to the Rack-1 RPC cards in the rear upper right.
    1. Route the expansion rack power control cables Callout label 2 through the frame to frame access holes near the rear cover upper hinges and on top of the sheet metal cable tray. See Figure 2.
    2. In Rack-1, route the expansion rack power control cables Callout label 1 on top of the sheet metal tray Callout label 2 and to the RPC cards Callout label 3. See Figure 3. Do not connect the cables until directed in the next step.

  4. Use Table 1 and Figure 4 to determine which RPC-1 card connector to plug the expansion rack power control cable to. Connect the cable to the RPC card.

  5. At the rear of the expansion rack being installed, find the power control cable that connects to the upper and lower DC-UPS connector E1-J7 (Figure 1). The loose end of the cable has a yellow label.
  6. Route the J7 cable from the prior step to the rear upper right of Rack-1 (the location of the RPC cards).
  7. Use Table 2 and Figure 4 to determine which RPC-2 card connector to plug the expansion rack power control cable to. Connect the cable to the RPC card.
