Connecting The Cables; Ac Input Power; Power States - HP Integrity rx2660 User's & Service Manual

To change the server from a rack mount to a rackless configuration, you need a Server Rackless
Mount Kit. The rackless mount kit comes with the HP Integrity rx2660 Server Pedestal Installation
Guide. Follow the steps in this installation guide to attach the pedestal to the server.

Connecting the Cables

This section describes the cables to connect to power the server and to provide LAN connectivity
for the server.

ac Input Power

The server can receive ac input from two different ac power sources. The power receptacles are
located at the rear of the chassis. They are labeled Power Supply 1 and Power Supply 2.
For the Data Center server, you can install a maximum of two power supplies in the server.
Installing two power supplies in the server provides 1+1 redundancy, meaning that if one power
supply fails, there is still enough power supplied to the server to operate. You must promptly
replace the failed power supply to restore 1+1 functionality.
A minimum of one power supply is required to power the server. If only one power supply is
installed in the server, there is no 1+1 capability.
For the Office Friendly server, two power supplies are required to power the server. The office
friendly server can run on one power supply, but runs quieter and more efficiently with two
power supplies installed.

Power States

The server has three power states:
• Standby power
• Full power
• Off
Table 3-4 lists the server power states.

CAUTION:
power should be completely removed from the server. You can do this by switching off the circuit
breakers which are part of the building installation, disconnecting or switching off a power
distribution unit, or by physically removing all power cords from the server.
NOTE:
If the power restore feature is set to Always On through the iLO 2 MP PR command,
the server automatically powers on to the full power state when the power cord is plugged in
to the server.
