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

  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 cables that connect to the upper and lower DC-UPS connectors Ex-J6 and Ex-J7. See Figure 1. The cables are normally found bundled together at the top 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.

  3. Route both 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. 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.

  6. Is there a second management console (MC 2) already installed in this storage complex?
    Note: The secondary management console should be labeled MC 2 on the front of the HMC laptop tray. You can verify the management console role (primary or secondary) by using the Query/Activate HMC Role Selection menu option. See ""MAP60A0 Display the HMC role selection.
