CANOGA PERKINS 9145E Network Interface Device Quick Start Guide - Manual (Page 2)

General Safety Considerations
Installation
The 9145E is suitable for installation in Network telecom-
munication facilities and locations where the National Elec-
tric Code (NEC) applies.
Cabling
The 9145E has been designed and tested and has passed
all the pertinent sections of GR-1089 and GR-63 for Type 2
and Type 4 equipment. This equipment does not have
direct electrical connection to outside plant equipment.
The Copper (RJ45) ports of the 9145E are not intended for
direct connection to “Outside Plant” metallic conductors and
shall be isolated (by channel banks or office repeaters) from
any connections to network or terminal equipment that lie
outside of the same building. The telecommunication inter-
face connections are considered to be, and meet the
requirements of, SELV circuits (not TNV).
Power
WARNING: The 9145E with redundant power supplies
must have both power supply cords disconnected before
servicing.
Wiring methods used for the connection of the equipment to
the AC or DC MAINS SUPPLY shall be in accordance with
the National Electrical Code, ANSI/NFPA 70, and the Cana-
dian Electrical Code, Part I, CSA C22.1.
The 9145E AC and DC units do not incorporate a discon-
nect device. The plug on the power supply cord is intended
to serve as the disconnect device. It is also recommended
that the AC socket-outlet shall be installed near the equip-
ment and shall be easily accessible.
The 9145E DC has a nominal operating DC voltage of -48
VDC and passes the minimal steady state DC operating
voltage of -40 VDC in accordance with GR-1089 Issue 4
which References American National Standards Institute
(ANSI) T1.315, Table 1. Additionally, Canoga Perkins
design allows for a minimal steady state of -36VDC.
The 9145E DC model is configured for a DC-I, Isolated DC
return.
1
Fuses
The 9145E is equipped with internal fuses. The AC model is
fused at 2A and the 48VDC at 1.5A.
Grounding
The 9145E AC & DC models are suitable for installation as
part of the Common Bonding Network (CBN).
The 9145E AC and DC are provided with a safety ground
connection which is capable of conducting any fault current
likely to be imposed such as fault current from sources
within the chassis. For the DC model use an approved 18ga
insulated wire connected to the terminal block’s middle con-
ductor. The plus and minus 48VDC conductors should be a
minimum of 20ga.
The AC will be grounded via the ground conductor of the
power cord and must be connected to an earthed mains
socket-outlet.
An electrical conducting path should exist between the
9145E chassis and the metal surface of the enclosure or
rack in which it is mounted or to a grounding conductor.
Electrical continuity should be provided by using thread-
forming type mounting screws that remove any paint or
nonconductive coatings and establish a metal-to-metal con-
tact. Any paint or other nonconductive coatings should be
removed on the surfaces between the mounting hardware
and the enclosure or rack. The surfaces should be cleaned
and an antioxidant applied before installation.
Lightning Protection
The intra-building ports of the 9145E are suitable for con-
nection to intrabuilding or unexposed wiring or cabling only.
The intra-building 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 intra-building interfaces only (Type 2 or
Type 4 ports as described in GR-1089-CORE, Issue 4) and
require isolation from the exposed OSP cabling. The addi-
tion of Primary Protectors is not sufficient protection in order
to connect these interfaces metallically to OSP wiring.
To protect the port against intra-building lightning surges,
the RJ45 ports of 9145E are suitable for connection to
shielded intra-building cabling grounded at both ends.
2
Surge Protection
The AC powered 9145E does not contain an internal Surge
Protective Device. An external Surge Protective Device
(SPD) should be used at the AC input of the network equip-
ment according to facilities procedures and as defined by
the National Electric Code (NEC).
ESD
The 9145E has been tested and passes the ESD require-
ments of Test level 4 for air and contact discharges. How-
ever to protect the exposed components from electrostatic
damage when removing or replacing the SFP optical mod-
ules requires the proper use of static mitigation procedures
such as properly wearing a wrist strap.
Operation Temperature
The 9145E is designed and Nationally Recognized Test
Laboratory (NRTL) tested and verified to operate between
0°C to 50°C, and type tested for short term emergency
ambient temperature of -5°C to 55°C
Fans
The 9145E models equipped with fans are constructed with
a Mid-front to mid-rear (EC class F2-R2) airflow scheme i.e.
draws air from the front and exhausts to the rear.
The 9145E models equipped with redundant fans are
designed to function normally over the entire long term
operating temperature range; in the unlikely event of a sin-
gle fan failure the 9145E will continue to perform normally
over the long term operation temperature range until a
replacement can be installed.
Fan replacement cannot be performed in the field. Call
Canoga-Perkins for an RMA number to arrange a repair.
Double Pole/Neutral Fusing
On the 9145E a fuse may be in place in the neutral path on
the AC power supply. After operation of the fuse, parts of
the equipment that remain energized might represent a
hazard during servicing.
