11 Appendix C: NEBS Considerations

: The CG2300 server intra-building Ethernet RJ-45 ports, COM ports, and/or Telco Alarms port are suitable for
WARNING
connection to intra-building or unexposed wiring or cabling only. The intra-building ports of the CG2300 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.
: The CG2300 server intra-building Ethernet RJ-45 ports, COM ports, and/or Telco Alarms port must use shielded intra-
WARNING
building cabling/wiring that is grounded at both ends.
The CG2300 server is suitable for installation in either the Common Bonding Network (CBN) or an Isolated Bonding Network
(IBN).
The CG2300 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 CG2300 systems is suitable for installation as either Isolation DC return (DC-I)
or Common DC return (DC-C). Where the CG2300 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 CG2300 server 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
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 CG2300 server 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.
