• Products that have AC power ports that are intended for deployments where an external Surge Protective
Device (SPD) is utilized at the AC power service equipment (see definition in National Electric Code).
• This product is designed for a Common Bonding Network (CBN) installation.
• This product can be installed in network telecommunication facilities or locations where the National
Electric Code applies.
• 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 nonconductive coatings and establish
a metal-to-metal contact. Any paint or other nonconductive 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.
• The DC return connection to this system should remain isolated from the system frame and chassis
(DC-I).
• The nominal DC operating voltage -48 VDC.
Review Installation Guidelines
Before installing the chassis, verify that these guidelines are met:
• Site is properly prepared so that there is sufficient room for installation and maintenance. For specifications
on the clearances required for chassis installation, see Clearance Requirements, on page 27.
• Operating environment is within the ranges listed in Environmental and Physical Specifications, on page
10
• Chassis is mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting the chassis in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
chassis in the rack.
• Airflow around the chassis and through the vents is unrestricted.
• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
• For cable requirements for optical module connections, see the Transceivers, Connectors, and Cables,
on page 12 section. Each port must match the wave-length specifications on the other end of the cable,
and the cable must not exceed the maximum cable length.
Procure Tools and Equipment
Obtain these necessary tools and equipment for installing the chassis:
• Number 1 and number 2 Phillips screwdrivers with torque capability to rack-mount the chassis
