HP StorageWorks XP Continuous Track (C-Track)

The HP StorageWorks XP Continuous Track (C-Track) remote support solution detects and reports
system problems to the HP Storage Technology Centers (STCs). C-Track transmits heartbeats, system
information messages (SIMs), and configuration information for remote data collection and monitoring
purposes. C-Track also enables the STCs to remotely diagnose issues and perform maintenance, if
you permit remote access.
The C-Track solution offers Internet connectivity and modem connectivity. If you choose the Internet-based
remote support solution, additional infrastructure and site preparation are required. This additional
preparation may include server and router requirements, which you and HP may be responsible for
implementing. For more information about the C-Track Internet-based solution, contact your HP
representative

Electrical requirements

The following topics explain the electrical requirements of your site to support the disk array.

Line voltage

Line voltage (AC) at the wall power outlet is a function of the local power utility and your building
power distribution network. Voltages outside of the operating range of the HP system can cause
intermittent system errors or a complete system shutdown. If required, an HP representative and your
electrician can determine the current line voltage and make recommendations. See
specific AC line voltage requirements.
Avoid the use of a line voltage conditioner.
Make sure that a power distribution unit (if used) provides the correct voltage to support your entire
system.

Branch circuit breakers

See chapter 3

Single-phase branch circuit breakers

The power cords supplied are specified for connection to a single-phase, 20-amp circuit.

Frequency

Usually, AC line frequency is determined by your local power providers. In some cases, electrical
power is supplied by generators. Shifts in AC line frequency can cause system errors. An HP
representative can monitor the frequency of the input AC line power and make recommendations, if
necessary. The HP system requires that the line frequency be within 0.5 Hz of the rated line frequency
(50 Hz or 60 Hz). See
