Lightning Protection
The intra-building ports of the 9145ELB are suitable for connection to intra-building 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) 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.
To protect the port against intra-building lightning surges, the RJ45 ports of 9145ELB are suitable
for connection to shielded intra-building cabling grounded at both ends.
ESD
The 9145ELB has been tested and passes the ESD requirements of Test level 4 for air and
contact discharges. However to protect the exposed components from electrostatic damage
when removing or replacing the small form-factor pluggable (SFP) optical modules requires the
proper use of static mitigation procedures such as properly wearing a wrist strap.
Operation Temperature
The 9145ELB 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 ambient temperature of minus
5°C to 55°C.
Fans
The 9145ELB models equipped with fans are constructed with a left to right airflow scheme. The
air is drawn from the left and exhausted to the right.
Fan modules are field replaceable without powering down the chassis. The device should not be
operating without a fan module installed for longer than 1 minute.
Emissions and Immunity
This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions:
• This device may not cause harmful interference
• This device must accept any interference received, including interference that may cause
undesired operation.
The authority to operate this equipment is conditioned by the requirements that no modifications
will be made to the equipment unless the changes or modifications are expressly approved by
the Canoga Perkins Corporation.
To Users of Digital Apparatus in Canada: This Class A digital apparatus meets all require-
ments of the Canadian interference-causing equipment regulations.
