Connecting the power control cables to power on the rack

About this task

Attention: After the RPC cables from this rack have been connected, DO NOT switch off or remove power to this expansion rack for any reason.

Procedure

You will perform the following steps for one expansion rack at a time. If you have additional expansion racks to install, you will be sent back here later.
At the rear of the expansion rack being installed, find the power control cables that connect to the left and right DC-UPS connectors Ex-J6 and Ex-J7. See Figure 1 or Figure 2. The cables are normally found bundled together at the rear of the expansion rack.
1. The loose end of the cable that connects to E1-J6 and E2-J6 has a gray label showing location R1-C1-P2xx.
2. The loose end of the cable that connects to E1-J7 and E2-J7 has a yellow label showing location R1-C2-P2xx.
  
  Note: The value of xx in P2xx varies by expansion rack.

Route both expansion rack power control cables to the RPC cards at the left rear and right rear of Rack-1.
1. Route the expansion rack power control cables through the frame to frame access holes near the top of the rack. See 2 in Figure 3.
  
  Note: If the rack power control cables cross an entire rack, route the cables along the bracket between the access holes. For example, Rack-3 cables cross Rack-2 to Rack-1. See 2 in Figure 3 and Figure 4.
2. In Rack-1, route the expansion rack power control cable labeled R1-C1-P2xx down the left side wall to R1-C1. See 2 in Figure Figure 4 and C1 in Figure 5. Do not connect the cable until directed in the next step.
3. In Rack-1, route the expansion rack power control cable labeled R1-C2-P2xx down the right side wall to R1-C2. See 2 in Figure 4 and C2 in Figure 5. Do not connect the cable until directed in the next step.

  Note: Rack-1 shown. PJAs E51, E52, E53, and E54 can also be present in Rack-2. DC-UPS locations are similar for models 98x and 8xE.
Use Table 1 and Figure 6 to determine which RPC-1 card connector to plug the expansion rack power control cable to. Connect the cable to the RPC card.

Use Table 2 and Figure 6 to determine which RPC-2 card connector to plug the expansion rack power control cable to. Connect the cable to the RPC card.
