Guidelines for DC-powered equipment
A DC-powered installation must meet the following requirements:
• Install the unit using a 25 amp external branch circuit protection device.
• For permanently connected equipment, incorporate a readily accessible disconnect in the fixed wiring.
• Use only copper conductors.
• Cabling for the system must be grounded on both sides.
• Normally, one power feed is used for each individual power supply.
NEBS platform guidelines
The following information applies to the Network Equipment-Building System (NEBS) version of the
platform.
This equipment meets NEBS requirements per GR-63-CORE.
This equipment is suitable for installation in the following:
• Network Telecommunication Facilities
• Locations where the National Electrical Code (NEC) applies
Important: The intra-building interfaces of this platform, including Ethernet, are suitable for connection
to intra-building or unexposed wiring or cabling only with shielded and grounded cables at both ends.
The intra-building ports of the equipment must not be metallically connected to interfaces that connect
to the outside plant (OSP) or its wiring.
Note: You should coat bare conductors with an appropriate antioxidant compound before you make
crimp connections. You should bring all unplated connectors, braided strap, and bus bars to a bright
finish and then coat them with an antioxidant before you connect them.
