If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration
to the effect of a lightning strike in your vicinity. The electromagnetic pulse that is caused by lightning or
other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic
fabric interconnects. You will want to consult experts in electrical surge suppression and shielding if you had
similar problems in the past.

Caution

Shock and Vibration Requirements

The fabric interconnect has been shock- and vibration-tested for operating ranges, handling, and earthquake
standards.

Grounding Requirements

The fabric interconnect is sensitive to variations in voltage that is supplied by the power sources. Overvoltage,
undervoltage, and transients (or spikes) can erase data from memory or cause components to fail. To protect
against these types of problems, ensure that there is an earth-ground connection for the fabric interconnect.
You can connect the grounding pad on the fabric interconnect either directly to the earth-ground connection
or to a fully bonded and grounded rack.

When you properly install the chassis in a grounded rack, the fabric interconnect is grounded because it has
a metal-to-metal connection to the rack. Alternatively, you can ground the chassis by using a customer-supplied
grounding cable that meets your local and national installation requirements. For U.S. installations, we
recommend 6-AWG wire. Connect your grounding cable to the chassis with a grounding lug (provided in the
fabric interconnect accessory kit) and to the facility ground.

You automatically ground AC power supplies when you connect them to AC power sources.

Note

An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure
or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using
thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a
metal-to-metal contact. Any paint or other non-conductive coatings shall be removed on the surfaces between
the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied
before installation.

Note

Planning for Power Requirements

The fabric interconnect includes two power supplies (1-to-1 redundancy with current sharing) in one of the
following combinations:
