HP Integrity rx2800 i2 Server User Service Guide

1
A maximum of 8 DIMMs are supported in a configuration with low line AC voltage and 2 processors.
NOTE: Configurations other than those listed in Table 43 (page 112) do not have 1+1 power
redundancy and are not supported.
Power redundancy is dependent on the number of power supplies, processors, and DIMMs in a
system. Additional components, such as HDDs or PCIe cards, do not impact power redundancy.
The server also supports power capping. Power capping operation can be observed through iLO
3. For more information, see the HP Integrity iLO 3 Operations Guide.
WARNING! To reduce the risk of personal injury from hot surfaces, allow the power supply or
power supply blank to cool before touching it.
CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless
all bays are populated with either a component or a blank.
To remove the component:
1. Determine how many hot-swap power supplies are installed:
• If only one hot-swap power supply is installed, power off and remove the power cord
from the server (“Powering off the server” (page 106)).
• If more than one hot-swap power supply is installed, continue with the next step.
2. Access the product rear panel (“Accessing the product rear panel” (page 110)).
3. Disconnect the power cord from the power supply.
4. Remove the hot-swap power supply.
WARNING! To reduce the risk of electric shock or damage to the equipment, do not connect
the power cord to the power supply until the power supply is installed.
To replace the component, see “Installing a hot-swappable power supply” (page 49).
Removing and replacing the access panel
To remove the access panel see “Removing the access panel” (page 50).
