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

Procedure

Complete the following steps for one expansion rack at a time, starting with Rack-2. If you have Rack-3, Rack-4, or Rack-5 to install, you are sent back here later.
At the rear of the expansion rack that is being installed, find the power control cable that connects to the left and right DC-UPS connector Ex-J6. See Figure 1 or Figure 2. The loose end of the cable has a gray label.

Figure 1. Location codes for the DC-UPS (Models 98x and 8xE, single-phase power) (rear)

Figure 2. Location codes for the DC-UPS (Models 98x and 8xE, three-phase power) (rear)
Route the J6 expansion rack power control cable to RPC-1 at the left 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.
  
  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.
2. In Rack-1, route the expansion rack power control cables to RPC-1 (R1-C1). Do not connect the cables until directed in the next step.

  Note: Models 980 and 98B shown, routing for other models is similar

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.

4	C1-J207
5	C1-J209

At the rear of the expansion rack that is being installed, find the power control cable that connects to the left and right DC-UPS connector Ex-J7 (Figure 1 or Figure 2). The loose end of the cable has a yellow label.
Route the J7 cable from the prior step to RPC-2 at the right rear of Rack-1, using the same method as the J6 cable. See Figure 3.

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.

Use Table 3 to find the expansion rack that you are installing. Go to the section indicated for that expansion rack.

Table 3. Installing a storage facility - next steps for expansion racks
Expansion rack that you are currently installing	Go to:
Model 85E all-flash (see note 8.a) Model 86E all-flash (see note 8.a) Model 88E Rack-2 with 8 (or fewer) flash enclosures Model 98F	Routing and connecting the Rack-2 PCIe and PCN cables to Rack-1
Model 88E Rack-2 with more than 8 flash enclosures Model 88E Rack-3	Routing and connecting the expansion rack SAS cables
Model 84E Model 98B	Routing and connecting the expansion rack FC-AL cables (business class models)
Model 85E Rack-2 Model 98E (single-phase) Rack-2 (see note 8.b)	Routing and connecting the Rack-2 PCIe and PCN cables to Rack-1
Model 86E Rack-2, Rack-3, Rack-4, Rack-5 Model 98E (three-phase) Rack-2 (see note 8.b) Model 98E Rack-3, Rack-4, Rack-5	Routing and connecting the Rack-2, Rack-3, Rack-4, or Rack-5 FC-AL cables
Notes: Examples of all-flash systems include models 982 and 98F, or machine types 5331, 5332, 5333, 5334, 9586 f you are unsure whether the rack is configured for single-phase or three-phase power, observe the J3-x PARTNER connectors at the rear of the DC-UPS. A single-phase DC-UPS has two "partner" connectors: J3-1 and J3-2. See Figure 1. A three-phase DC-UPS has three "partner" connectors: J3-1, J3-2 and J3-3. See Figure 2.
