HP 3PAR T-Class Installation and Deinstallation Guide

Verifying Acclimatization
Before being powered on, the storage system may require up to 24 hours to acclimatize to the
new operating environment when outside-to-inside conditions vary greatly. If there is a possibility
the storage system or its components may have experienced environmental changes during transit,
verify the amount of acclimatization time for the storage system before proceeding with the power-on
sequence.
CAUTION: To prevent potential damage to system hardware, do not power on the storage system
until it has properly acclimatized.
CAUTION: If condensation is present after the 24 hour acclimatization period, wait until all
condensation evaporates before completing the power-on sequence.
Completing the Power-On Sequence
After checking or completing all cable connections and verifying the storage system is stationary,
perform the power-on sequence:
1. Connect the maintenance PC to the highest numbered controller node and initiate a terminal
emulation session as described in “Connecting the Maintenance PC” (page 191) for monitoring
and recording boot activity.
2. Access the rear of the system and verify all PDUs are set to the OFF position.
3. Set each of the power supplies to the ON position.
4. Set the safety breakers on the PDUs to the ON position (“Setting the Safety Breakers to the
ON Position” (page 77)).
Figure 70 Setting the Safety Breakers to the ON Position
5. Set both battery switches in each of the BBUs to the ON position.
NOTE: For T800 systems, two PDUs are accessible from the rear and the remaining PDUs
are accessible at the front of the storage system.
