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

Procedure

  1. You will perform the following steps for one expansion rack. If you have additional expansion racks to install, you will be sent back here later.
  2. To access the rear of the PPS, unfasten Callout label 1 and then rotate the upper and lower sets of power distribution units (PDUs) away from the rear of the PPS, as shown in Figure 1.

  3. Remove the tailgate frame bracket. Remove two screws  2  as shown in Figure 2. Loosen but do not remove the two top screws  1 . Slide the bracket out.

  4. At the rear of the expansion rack being installed, find the power control cable that connects to the PPS sequencer module connector  J1  in the upper PPS. The loose end of the cable has a gray label.

  5. Route the  J1  cable from the prior step to the rear upper right of Rack-1 (the location of the RPC cards). The cable route is through the frame to frame access holes near the rear cover upper hinges.
  6. Use Table 1 and Figure 4 to determine which RPC1 card connector to plug the expansion rack power control cable to. Connect the cable to the RPC card.

  7. At the rear of the expansion rack being installed, find the power control cable that connects to the PPS sequencer module connector  J2  in the upper PPS. The loose end of the cable has a yellow label.

  8. Route the  J2  cable from the prior step to the rear upper right of Rack-1 (the location of the RPC cards). The cable route is through the frame to frame access holes near the rear cover upper hinges.
  9. Use Table 2 and Figure 6 to determine which RPC2 card connector to plug the expansion rack power control cable to. Connect the cable to the RPC card.

  10. Are you here to install the cables for Rack-2?
  11. All FC-AL cables in Rack-2 are already connected, none of them go to Rack-1. The Rack-2 SPCN and PCIe cables will be connected to Rack-1. Go to Routing and connecting the Rack-2 SPCN and PCIe cables.
