Section 3 — Kayenne Frames
The Kayenne system uses a Panel Control Unit (PCU). This 3RU rack-
mount frame powers the Control Panel and Touch Screen Menu Panel(s),
and houses the processors for these devices. The PCU has one processor for
the Control Panel, and another processor for the standard Touch Screen
Menu Panel. An additional Menu Panel processor is available as an option.
The PCU has an internal Ethernet switch, used for Menu Panel processor
communications. Six Ethernet ports are available on the back. Two ports are
used internally for the Menu Panels. An additional Ethernet port is used for
Control Panel processor communications.
PCU Power Supplies
The Kayenne PCU frame has two power supplies standard. The frame will
continue to operate without interruption should a single power supply fail.
