Powering-Down The Hp Server; Connecting Ac Power To Multiple-Server Configurations - HP Integrity rx4610 User Manual

Powering-Down the HP Server

To power-down the HP Server, complete the following procedure:
1. Log off all users and, if necessary, back up the system files.
Schedule the power down for a time when the Server being down will
◊
affect the fewest users.
If you will be doing any kind of hardware or software upgrade, ensure
◊
the Server's data has been backed up.
Follow instructions in your network operating system (NOS)
◊
documentation to gracefully shut down all networking software and
applications.
WARNING The power supply will continue to provide standby current to
the HP Server until the power cable is disconnected from the
rear panel.
2. Logoff and exit the operating system. The following prompt appears:
Shell>
3. At the Shell> prompt, press and hold the Power button for several seconds.
Holding the Power button in for several seconds shuts down the server.
4. Disconnect the power cord from the power source.
Normally this completes the power-down procedure.

Connecting AC Power to Multiple-Server Configurations

The HP Server temporarily draws a large "inrush current," when first connected to
an AC power source. This also occurs when the Server is in a standby mode
(power is turned off, but the power cord is plugged into AC power). The inrush
current is much greater than the Server's normal operating current and generally,
the AC power source can handle the normal inrush current.
However, if you install several HP Server on one circuit, precautions are
necessary. If there is a power failure and power is then restored, all the servers
immediately begin to draw inrush current at the same time. If the circuit breakers
on the incoming power line have insufficient capability, the breaker may trip and
thus prevent the servers from powering up.
