CAUTION:
Protect the SKM 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 an SKM 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 SKM 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 SKM 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 an SKM is not recommended.
Unpacking
Place the shipping carton as close to the installation site as possible. Before unpacking the SKM,
inspect the shipping carton for damage that may have occurred during shipment. If you detect any
damage, notify the carrier and HP before unpacking the unit.
To unpack the SKM:
1. Open the top of the shipping cartons.
2. Carefully lift the units out of the boxes and remove the packing materials.
3. Place the units on a stable work surface.
NOTE:
Inspect the units for any damage that may have occurred during shipment. If damage is
detected, contact your authorized service representative.
4. Remove the accessory kits and documentation from the shipping cartons. Set them aside for later
use.
