Connecting the mainline power cables on the racks (plug-in)

Before you begin

DANGER
An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (D004)

Repeat steps 1 through 3 for each rack that you install.

Procedure

  1. Switch the customer circuit breaker to Off for each mainline power cable being installed.
  2. Attention: Use lockout and tagout procedures as defined in the Electrical Safety for IBM® Customer Engineers.
  3. Verify the CB1 main line switch at the rear of each DC-UPS is set to Off (down).
  4. Connect each storage facility mainline power cable connector to the customer ac power outlet.
  5. If the rack has a top exit line cord feature, pull the line cords up to remove excess slack, and tighten the adjustable clamp bracket Callout label 2 into the clamp housing Callout label 1 to secure the line cords. Do not excessively tighten the clamp bracket. See Figure 1.
