should not be fed into slave frames (1U or 3U).

1U Frame Control Connections
Figure 30: Pyxis 1U Frame Rear Panel
This section discusses the rear connectors and ports on a 1U Pyxis frame. Most port settings and
configurations are common with the 3U panel (refer to Section 5.1 for detail). This section will
concentrate on the differences between the two frames.
5.2.1 Interconnections and Safety
Due to the nature of some of the data ports, especially high-speed video ports, it is impossible to
include fuse protection therefore; any equipment attached to the data ports must comply with Clause
4.7 of IEC/EN60950-1.
5.2.2 Pin-Outs
Pin outs of all connectors are the same as on a 3U Frame with the exception of Port3/AES as
defined in section 5.2.4
5.2.3 Ethernet
The 1U chassis only has provision for a single controller, an Ethernet port is provided to allow TCP/IP
control of this.
