Organizing Interface Cables
Arrange network cables as follows to prevent them from dislodging or developing
stress points:
 Secure cables so that they are not supporting their own weight as they hang to
the floor.
 Place excess cable out of the way in neatly coiled loops.
 Use fasteners to maintain the shape of cable loops.
Chassis Grounding
To meet safety and electromagnetic interference (EMI) requirements, and to ensure
proper operation, the device must be adequately grounded before power is
connected. A two-hole grounding lug is provided on the rear of the chassis to
connect the device to earth ground (see Figure 4 on page 14).
The grounding cable must be American Wire Gauge (AWG) number-14 single-strand
wire cable and must be able to handle up to 6 ampere (A).
To ground the device before connecting power, you connect the grounding cable to
earth ground and then attach the cable to the lug on the rear of the chassis.
Connecting Power
This section describes how to connect AC and DC power to a device.
AC Power
The AC power cord shipped with the device connects the device to earth ground
when plugged into an AC grounding-type power outlet. The device must be
connected to earth ground during normal operation.
To connect AC power to the device:
1. Locate the power cord or cords shipped with the device, which has a plug
appropriate for your geographical location.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strip to the ESD point on the chassis.
CAUTION: Before device installation begins, a licensed electrician must attach a
cable lug to the grounding cable that you supply. A cable with an incorrectly
attached lug can damage the device (for example, by causing a short circuit).
