HP Performance-Optimized Datacenter, 12 m (40 ft) User Guide

Installation 18
10.
Power up the servers and other IT equipment. Also simultaneously power off any portable heaters, if
used.
When powering up each server unit, HP recommends that heat be equally distributed across the
length of the HP POD. Power on one server unit at a time moving from one rack to the adjacent rack.
Do not power on server units in the same rack before moving to the next adjacent rack.
NOTE: HP POD space temperature rate of change should not exceed 18°F (10°C) per hour
with operating servers.
11. When the cold aisle space temperature reaches 75°F (24°C), switch the water supply flowing
through the HP POD heat exchangers from heating mode to cooling mode.
12. Continue to monitor the cold aisle space temperature, verifying that it does not drop to 50°F (10°F)
or below.
13. If the cold aisle space temperature drops to near 50°F (10°C) or below, HP recommends:
o Raising the cooling water supply temperature to a warmer temperature setpoint.
o Reducing the cooling water supply flow by manually turning the main water valve to decrease
water flow.
14. To enable the HP POD interior temperature space to stabilize, enable the HP POD and the
equipment to run at idle for at least 8 hours.
NOTE: Monitor the ECS when the HP PODs goes into peak operation. You might have to
increase cooling capacity, and if the main water valve is not fully open, then you must adjust
the valve needs.
Commissioning the HP POD
Commissioning your HP POD is an optional service and is customized based on your facility. A typical
commissioning process includes the following tests:
• Tighten the electrical busway connections.
• Verify accurate electrical installation.
• Verify accurate mechanical installation.
• Test the operation of the ECS and Cooling controls.
• Test the operation of the smoke detection system.
• Test the operation of EPO system.
• Test the operation of the analog and digital phone system (optional).
• Verify initial IT start-up.
• Conduct an infrared scan of all electrical connections under the start-up IT load.
• Verify accurate cooling under start-up IT load.
• Provide the HP POD operation owner training.
