CHAPTER 3: Configuration and Installation
3.2 Site Requirements
Power:
The FradSwitch A/S 3 Port unit should be installed within 5 ft. (1.5 m) of
an easily accessible, grounded AC outlet capable of furnishing power at the voltage
it needs (100 to 230 VAC).
Control-Port Connections:
The FradSwitch A/S 3 Port has an RJ-45 connector for
its asynchronous supervisory-control port (see the
Appendix
for this port’s pinout).
Main-Link Connections:
The FradSwitch A/S 3 Port has three main-link
connectors. What type of connectors these are depends on which interface(s) you
ordered for your Switch:
RS-232:
DB25 female
X.21:
DB25 female patched to DB15 female with included adapter cable
V.35:
DB25 female patched to M/34 female with included adapter cable
RS-530:
DB25 female
DDS:
RJ-48 female
The pinouts for these interfaces are listed in the
Appendix
.
Front and Rear Clearance:
When the FradSwitch A/S 3 Port is installed in a
19" rack, allow at least 36" (90 cm) of clearance in front of it for operator access
and 4" (10 cm) of clearance behind it for interface-cable connections.
Environment:
The ambient temperature in which the FradSwitch A/S 3 Port
operates should be 32 to 122˚ F (0 to 50˚ C), at a relative noncondensing humidity
of not more than 90%.
