2-2 Installation and Setup
2.3 Installation and Setup
RIC-E3/ETH and RIC-T3/ETH are a standalone devices intended for tabletop or
19-inch rack installation. They are delivered completely assembled. No provision is
made for bolting the unit on the tabletop.

To install RIC-E3/ETH or RIC-T3/ETH:
1. Determine the required configuration of RIC-E3/ETH or RIC-T3/ETH according
to your application, and set the internal jumpers and switches accordingly.
2. Connect the E3/T3 lines and the LAN.
3. Connect power to the unit.
Setting the Internal Jumpers
This section provides information on the functions of the RIC-E3/ETH and
RIC-T3/ETH jumpers, and gives step-by-step instructions for performing the
internal settings. The default settings are also listed.
Locations of Jumpers and Switches
RIC-E3/ETH and RIC-T3/ETH include three printed circuit boards (PCBs): the main
board, E3/T3 interface board, and Ethernet interface board (see Figure 2-1,
Figure 2-2, Figure 2-3 and Figure 2-4).
The main board contains the common signal processing circuits. Two jumpers, JP1
and JP2, are provided for user settings.
The E3/T3 interface boards provide connection to the E3/T3 links. The E3/T3
boards contain jumpers for selecting the E3/T3 cable length.
The Ethernet interface board provides LAN connection. The Ethernet board
contains an 8-section DIP switch for the interface configuration.
Opening the Case
To reach the internal jumpers and switch of RIC-E3/ETH and RIC-T3/ETH, it is
necessary to open its case.
Access to the inside of RIC-E3/ETH and RIC-T3/ETH is permitted only to
authorized and qualified service personnel.
To avoid accidental electric shock, always disconnect the interface cables and
the power cord before removing the units from their casing.
Line voltages are present inside RIC-E3/ETH and RIC-T3/ETH when they are
connected to power and/or to the lines. Moreover, under external fault
conditions dangerous voltages may appear on the lines connected to the units.
Any adjustment, maintenance, and repair of the opened equipment under
voltage should be avoided as much as possible and, when absolutely
necessary, should be carried out only by a skilled technician who is aware of
the hazard involved. Capacitors inside the instruments may still be charged
even after the instruments have been disconnected from their power source.
