Surge Protection
The AC powered 9145E10G does not contain an internal Surge Protective Device. An external
Surge Protective Device (SPD) should be used at the AC input of the network equipment accor-
ding to facilities procedures and as defined by the National Electric Code (NEC).
Grounding
The 9145E10G AC & DC models are suitable for installation as part of the Common Bonding
Network (CBN).
All 9145E10G models are provided with a safety ground connection which is capable of conduc-
ting 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
conductor. The plus and minus 24 VDC and 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 9145E10G 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 non-
conductive coatings and establish a metal-to-metal contact. 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 9145E10G are suitable for connection to intrabuilding or unex-
posed 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 interfa-
ces 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 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 9145E10G are suita-
ble for connection to shielded intra-building cabling grounded at both ends.
ESD
The 9145E10G 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 SFP or XFP optical modules requires the proper use of static
mitigation procedures such as properly wearing a wrist strap.
