minutes to power up, while an enclosure with fewer blades might take less time. Server blades are powered up incrementally, starting from device bay 1.

When first initialized, the Onboard Administrator programs the mezzanine cards on the blades during discovery. After the mezzanine cards are programmed, powering up the enclosure takes only 1 to 2 minutes.

The enclosure and the Insight Display now have power. Configure the enclosure ("Running the Insight Display installation steps" on page 65) using the Insight Display.

PDU installation

The PDU can be installed in either a 1U or a 0U configuration. For more information about installing the PDU in the rack, see the installation instructions that came with the PDU.

IMPORTANT: Rack-based single-phase PDUs cannot be used with a three-phase power configuration.

IMPORTANT: Total VA load of the attached enclosures should not exceed the VA capacity of the PDU. Do not exceed the rated current on circuit breakers.

To connect power to the PDU:

1.Connect the AC power cables to the power connectors on the rear of the enclosure corresponding to the power supply that was populated on the front of the enclosure.
