Page 14: Site Requirements
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). -
Page 15: Hardware Configuration
FRADSWITCH A/S 3 PORT 3.3 Hardware Configuration The FradSwitch A/S 3 Port contains two different types of printed circuit boards, as shown in Figure 3-1 below. The main board contains most of the FradSwitch’s circuits, and has two jumpers. Three main-link interface boards carry interface- specific logic. -

CHAPTER 4: Operation 4.2 Basic Operating Instructions and Indications Once you install and configure the FradSwitch A/S 3 Port, it normally operates unattended. After initial setup, operator intervention is only required when the Switch has to be reconfigured or if something goes wrong. Note that the Switch stores its configuration in nonvolatile RAM (NVRAM), so it won’t lose its configuration if it loses power. -
Page 27: Upgrading The Switch's Firmware
FRADSWITCH A/S 3 PORT 4.3 Upgrading the Switch’s Firmware Because the FradSwitch A/S 3 Port has flash memory, you can upgrade its firmware without replacing its EPROMs. To do so, take these steps: 1. Connect a PC running terminal emulation to the switch’s control port. Configure the terminal emulator to transmit and receive at 9600 bps using no parity, 8 data bits, and 1 stop bit (“9600,N,8,1”). - Page 28 CHAPTER 4: Operation 5. Select option 12.
