2-2 Hardware Configuration Information SPS-6, SPS-12
Main Links Connections
The SPS-6 has six main links connectors and the SPS-12 has twelve main links
connectors. The main links connector depends on the ordered interface:
• RS-232/V24: 25-pin D-type, female connector
• X.21: 25-pin D-type, female connector
• V.35: 25-pin D-type, female connector
• RS-530: 25-pin D-type, female connector
• V.36/RS-449: 37-pin D-type, female connector (via adapter cable)
• IR-ETH: 10BaseT, UTP cable, RJ-45
• ISDN: S-interface, UTP cable, RJ-45
• DDS: CSU/DSU interface, UTP cable, RJ-45.
Front and Rear Panel Clearance
If you install the SPS-6/SPS-12 in a 19" rack, allow at least 90 cm (36 inches) of
frontal clearance for operator access. Allow at least 10 cm (4 inches) clearance at
the rear of the unit for interface cable connections.
Ambient Requirements
The ambient operating temperature of the SPS-6/SPS-12 should be 0 to 50°C (32
to 122°F), at a relative humidity of up to 90%, non-condensing.
2.4 Hardware Configuration Information
General Information
The SPS-6/SPS-12 contains two different types of printed circuit boards. Figure 2-1
shows an internal view of the SPS-12 with the different boards.
The main board. This board contains most of the unit circuits and jumpers.
Twelve main link interface boards for SPS-12 or six boards for SPS-6, which
determine the interface type. The appropriate board is factory-installed in
accordance with your order, and is not field-replaceable. For further details, see
the RAD Packet Switching Guide.
The default settings of the unit jumpers are suitable for most applications. Check the
default positions explained below. If the requirements for your application are
different, set the internal jumpers in accordance with the requirements, before the
installation.
All other configuration actions are performed using the SPS-6/SPS-12 command
facility, after the installation is completed. Information and detailed instructions for
these operations appear in the RAD Packet Switching Guide.
