HP Integrity rx8620 Server User Service Guide

NOTE: If a UPS is used, refer to applicable UPS documentation for information on connecting
the server and checking the UPS output voltage. UPS User Manual documentation is shipped
with the UPS. Documentation may also be found at http://www.hp.com/racksolutions
To check the voltage, follow these steps:
1. Verify that site power is off.
2. Open the site circuit breakers.
3. Verify that the receptacle ground connector is connected to ground. Refer to Figure 4-4 for
connector details.
4. Set the site power circuit breaker to on.

5. Verify that the voltage between receptacle pins x and y is between 200–240 VAC.
6. Set the site power circuit breaker to off.
7. Ensure that power is removed from the server.
8. Route and connect the server power connector to the site power receptacle.
• For locking type receptacles, line up the key on the plug with the groove in the receptacle.
• Push the plug into the receptacle and rotate to lock the connector in place.
WARNING! Do not set site AC circuit breakers serving the processor cabinets to on before
verifying that the cabinet has been wired into the site AC power supply correctly. Failure
to do so can result in injury to personnel or damage to equipment when AC power is applied
to the cabinet.
9. Set the site power circuit breaker to on.
WARNING! SHOCK HAZARD Risk of shock hazard while testing primary power. Use
properly insulated probes. Be sure to replace access cover when finished testing primary
power.
10. Set the server power to on.
11. Check that the indicator light on each power supply is lit.
Connecting AC Input Power
The server can receive AC input from two different AC power sources. If two separate power
sources are available, each source can be plugged into the server, increasing system reliability if
one power source fails. The main power source is defined to be A0 and A1. The redundant power
source is defined to be B0 and B1. For the AC power input label scheme, see Figure 4-5.
