Standard power up procedure
Perform the following procedures in the exact order in which they are listed.
Site electrical
Close all POD site power feeder breakers and monitor for any effects that are not standard.
Site chilled water
1.Open the POD supply chilled water isolation valve.
2.If necessary, vent the air from the chilled water return header.
3.Open the POD return chilled water isolation valve.
4.Verify that audible flow noises are present.
ECS and EPO
Verify the following on using the ECS touchscreen and EPO indicators:
•The ECS panel is operational and displays the user interface.
•The POD lighting is operational.
•The EPO system is set to Armed (White) or Bypass (Green).
POD operation
1.On the ECS touchscreen, verify that all system components are operational (green) and no alarm conditions exist.
2.On the ECS touchscreen, verify that all system parameters are operating normally.
3.On the ECS touchscreen, verify that the POD chilled water flow rate is established on the flow rate indicator.
4.In the hot aisle, close the power drop box breakers for each rack and ensure that the IT equipment is operating.
5.In the cold aisle, monitor the flow control position, chilled water flow, and POD temperatures.
6.Wait five minutes to allow the system to stabilize.
The HP POD 20c is now fully operational and the control system automatically controls the fan and the flow control valve position.
Cold weather HP POD 20c power up procedure
This procedure is for your reference only and assumes that the POD was fully commissioned and powered up by HP before being turned over to you.
Before beginning the power up procedures in this section, verify that the POD is not in operation and that the internal ambient temperature of the POD is less than 10ºC (50ºF). If the internal ambient temperature of the POD is greater than 10ºC (50ºF), see "Standard HP POD 20c power up procedure (on page 69)."
IMPORTANT: The minimum acceptable inlet temperature for IT equipment is 10ºC (50ºF).
