WARNING: The CG1200 intra-building Ethernet RJ-45 ports, COM ports, and/or Telco Alarms port are
suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building ports of
the CG1200 MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring.
These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as
described in GR-1089) and require isolation from the exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
WARNING: The CG1200 intra-building Ethernet RJ-45 ports, COM ports, and/or Telco Alarms port must
use shielded intra-building cabling/wiring that is grounded at both ends.
The CG1200 server is suitable for installation in either the Common Bonding Network (CBN) or an
Isolated Bonding Network (IBN).
The CG1200 server is suitable for installation in Network Telecommunication Facilities (NTF) and
locations where the National Electric Code (NEC) applies, but is not suitable for installation in Outside
Plant (OSP) installations.
The Battery Return (BR) for the -48V DC powered CG1200 systems is suitable for installation as either
Isolation DC return (DC-I) or Common DC return (DC-C). Where the CG1200 is installed with a common
DC return, the ampacity of the conductor connecting the equipment frame to the battery return conductor
shall be equal to or greater than 13 amps.
This active alarm provides an indication that the air filter should be inspected and/or replaced.
