CAUTION:
Protect the VLS from power fluctuations and temporary interruptions with a regulating uninterruptible
power supply (UPS). This device protects the hardware from damage caused by power surges and
voltage spikes and keeps the system in operation during a power failure.
When installing a VLS connected to more than one disk array, you may need to use additional power
distribution devices to safely provide power to all devices. Observe the following guidelines:
•
Balance the device power load between available AC supply branch circuits.
•
Do not allow the overall system AC current load to exceed 80 percent of the branch circuit
AC current rating.
•
Do not use common power outlet strips for this equipment.
•
Provide a separate electrical circuit for each device.
Electrical grounding requirements
The VLS must be grounded properly for proper operation and safety. In the United States, you must install
the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, as well
as any local and regional building codes. In Canada, you must install the equipment in accordance
with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other countries,
you must install the equipment in accordance with any regional or national electrical wiring codes, such
as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you
must be sure that all power distribution devices used in the installation, such as branch wiring and
receptacles, are listed or certified grounding-type devices.
Because of the high ground-leakage currents associated with multiple VLS and servers connected to the
same power source, HP recommends the use of a power distribution unit (PDU) that is either permanently
wired to the building's branch circuit or includes a non-detachable cord that is wired to an industrial-style
plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for this
purpose. Using common power outlet strips for a VLS is not recommended.
Identifying the shipping carton contents
Unpack the VLS shipping cartons and locate the materials and documentation necessary for installing the
VLS. All the rack mounting hardware and documentation necessary for installing a VLS node into a rack
is included in the node shipping carton. All the rack mounting hardware and documentation necessary
for installing a VLS disk array into a rack is included in the disk array shipping carton.

NOTE:
In addition to the contents of the shipping carton(s) and an existing EVA, you will also need a #1 Phillips
screwdriver, a #2 Phillips screwdriver, 1 Ethernet cable to connect to the existing external network, and 4–8 FC
cables to connect from the nodes to the external FC fabrics/switches. These are not included with the VLS300.
