WARNING: The CG2200 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 CG2200 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 CG2200 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 CG2200 is suitable for installation in either the Common Bonding Network (CBN) or an Isolated
Bonding Network (IBN).
The CG2200 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 CG2200 systems is suitable for installation as either
Isolation DC return (DC-I) or Common DC return (DC-C). Where the CG2200 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.
The CG2200 can be configured with an optional air filter that is installed behind the front bezel.
The air filter material is UAF Quadrafoam (25 PPI), has a thickness of 6.35mm, flammability rating of
UL94-HF1, and meets the minimum dust arrestance of 65% (ASHRAE 52.1-1992) per documentation
found at
http://www.uaf.com . The air filter can be purchased directly from Universal Air Filter (UAF)
by calling (618) 271-7300 or emailing [email protected] and ordering part number K00737-001. When
placing an order provide the attached drawing to verify receipt of the proper air filter.

Recommended Air Filter Replacement Schedule: Every 6 months
The CG2200 is equipped with thermal sensors to monitor the internal temperature of the system. If the
air filter gets clogged so that the fans are not able to pull air through the system, the internal temperature
will rise causing a MNR and/or MJR telco alarms manager (TAM) LED to be asserted. This active alarm
provides an indication that the air filter should be inspected and/or replaced.
