Powering On The Storage System - HPE 3PAR StoreServ 9000 Customer Self Install Manual

Powering on the storage system

Prerequisites
• The acclimatization process has completed for the storage system components. Do not power on the
storage system until it is fully acclimatized. Allow up to 24 hours, and if condensation is still present,
wait until fully evaporated before powering on. If small drops of water can be seen on any of the
surfaces, condensation is present.
• The storage system does not exceed the ratings of the power sources and adheres to the guidelines in
the HPE 3PAR StoreServ 9000 Storage Site Planning Manual available at the Hewlett Packard
Enterprise Information Library website:
www.hpe.com/info/storage/docs
• Drives or slot-filler blanks are in all bays for proper thermal control.
• If power connections are underneath the rack, route the PDU power cables under the bracket at the
bottom rear of the rack.
Procedure
1. On all PDUs, turn on the power by setting all circuit breakers to the ON position.
For a physical service processor (SP), the power starts automatically when the PDUs are powered on.
Alternatively, use the power reset button. For the drive enclosures, the power starts automatically,
because there is no power switch.
2. On each controller node, turn on the power by setting the power switch to the ON position.

3. Wait approximately 10 minutes for completion of the storage system power-on/boot sequence.
4. At the rear of the storage system, verify that all status LEDs are illuminated green. If any of the LEDs
are amber, troubleshoot the issue before continuing to power on. There is an LED status for the
controller nodes, drive enclosures, and power supply units.
