Table 29: Site Electrical Wiring Guidelines (continued)
Guidelines Site Wiring Factor
To reduce or eliminate the emission of RFI from your site wiring:
•
Use a twisted-pair cable with a good distribution of grounding conductors.
•
Use a high-quality twisted-pair cable with one ground conductor for each data signal
when applicable, if you must exceed the recommended distances.
Radio frequency
interference (RFI)
Provide a properly grounded and shielded environment and use electrical
surge-suppression devices.
Strong sources of electromagnetic interference (EMI) can cause the following damage:
•
Destruction of the signal drivers and receivers in the device.
•
Electrical hazards as a result of power surges conducted over the lines into the
equipment.
TIP: If your site is susceptible to problems with EMC, particularly from lightning or radio
transmitters, you might want to seek expert advice.
Electromagnetic
compatibility (EMC)
WARNING: The intrabuilding port(s) of the equipment or subassembly is suitable for
connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s)
of the equipment or subassembly MUST NOT be metallically connected to interfaces
that connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding
interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE), and require
isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient
protection to connect these interfaces metallically to OSP wiring.
MX10016 Rack Requirements
The MX10016 chassis is designed to be installed in four-post racks. Table 30 on page 94 provides the rack
requirements and specifications for the MX10016 router.
