Powering-Down The Hp Netserver; Connecting Ac Power To Multiple-Server Configurations - HP D6030A - NetServer - E50 Installation Manual

Chapter 2

Powering-Down the HP NetServer

1. Log off all users and if necessary, back-up files.
Schedule the power down for a time when the fewest users will be
affected by the NetServer's downtime.
If you will be doing any kind of hardware or software upgrade, be sure
your NetServer's data has been backed up.
2. Follow instructions in your network operating system (NOS) manufacture's
documentation to gracefully shut down all networking software and
applications.
3. Press the power switch on the HP NetServer's control panel when
prompted by the operating system.
Normally this completes the power down procedure.
NOTE
The power supply will continue to provide standby current to
the NetServer until the power cable is disconnected from the
rear panel.

Connecting AC Power to Multiple-Server Configurations

The HP NetServer temporarily draws a large "inrush current," when first
connected to an AC power source. This also occurs when the NetServer is in a
standby mode (power is turned off and the power cord is plugged into AC power).
The inrush current is much greater than the NetServer's normal operating current
and generally, the AC power source can handle the normal inrush current.
However, if you install several HP NetServers 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.
When preparing your site for installation, allow for the additional inrush current.
