FCD-E1LC Ver. 1.0 Site Requirements and Prerequisites 2-3
Whenever feasible, during installation works use standard ESD protection wrist
straps to discharge electrostatic charges. It is also recommended to use garments
and packaging made of antistatic materials or materials that have high resistivity,
yet are not insulators.
It is also important to make sure that other equipment, in particular customer’s
data equipment connected to FCD-E1LC serial data and Ethernet ports, is properly
grounded (connected to the protective, or safety, ground) before attempting to
connect it to the FCD-E1LC.
2.2 Site Requirements and Prerequisites
Physical Requirements
The FCD-E1LC are intended for installation on desktop and shelves. All the
connections are made to the rear panel.
For installation in 19-inch racks, RAD offers a rack mount (RM) kit. An FCD-E1LC
installed with the RM kit occupies a height of 1U. For installation of one or two
units in a 19-inch rack, refer to the
Rack Mounting Kit for 19-inch Racks
guide
that comes with the RM kit.
Power Requirements
FCD-E1LC has a wide range AC/DC power supply, and therefore can be powered
either by AC or DC sources:
• AC-powered FCD-E1LC units should be installed within 1.5m (5 feet) of an
easily-accessible grounded AC outlet capable of furnishing 100 to 240 VAC,
50/60 Hz (nominal mains voltage).
• DC-powered FCD-E1LC units require a -48 VDC or -60 VDC (nominal) power
source.
Reversing the DC supply voltage polarity will not damage the FCD-E1LC, but the
internal protection fuse will not function.
Connections
This section presents general requirements regarding the connections to the
various FCD-E1LC interfaces. Note that your unit cannot include all the interfaces
listed below.
If you need specific information regarding pin allocations in the FCD-E1LC
interface connectors and wiring data for adapter cables, refer to
Appendix A
.
Main and Sublink Connections
FCD-E1LC main and sub ports support two interfaces: 120Ω balanced interface
for operation over two twisted pairs, and 75Ω unbalanced interface for operation
