HP Performance Optimized Datacenter 20c User Guide - China

Power up procedure 71
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 the ECS screen and EPO indicators:
• The ECS panel is operational and displaying 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 5 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 70)."
IMPORTANT: The minimum acceptable inlet temperature for IT equipment is 10ºC (50ºF).
Follow the same checks and startup procedures as described in "Standard HP POD 20c power up procedure
(on page 70)." However, the POD has internal and outdoor ambient temperatures that are below the
minimum operational temperatures for servers. The additional steps required are contained in this procedure.
This process ensures personnel safety during the electrical start up of the HP POD 20c.
WARNING: To avoid risk of personal injury or loss of life, do not open an energized POD
electrical cabinet without an energized work permit and appropriate PPE.
