Grounding
The 9161 AC & DC models are suitable for installation as part of the Common Bonding Network
(CBN).
The 9161 AC and DC 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 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 9161 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 nonconduc-
tive 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.
ESD
The 9161 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 remo-
ving or replacing the XFP optical modules requires the proper use of static mitigation procedures
such as properly wearing a wrist strap.
Operation Temperature
The 9161 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 9161fans 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.
