Front and Rear PanelsFigure 3
Front Panel
The front of the unit consists of eight card slots in a 2U chassis. The four full-length slots
on the left side can be lled with change over cards. The four half-length slots on the
right side are used for two hot swappable power supply modules, a frame controller card
and a SNMP chassis management card.
Indicators
Each of the change over cards provides indication of the current switch state (A or B
selected for output), input MADI signal presence, card status, out of service and fault
status. Power supply modules have power on indication and the frame controller card
has a processor active indicator. The chassis management card has additional power,
temperature and cooling status indication.
Front Panel Control
There is a switch located on the front of each change over card that allows local manual
override of the output relay position in the event of a control system failure. In the Auto
(middle) position, the remote control input on the change over frame controller card
determines which output is active.
Rear Panel
The rear panel of the unit has four full-length card slots on the right side for MADI I/O
modules.
Each module supports four MADI signals (up to 256 channels) connected to and from the
I/O, primary and backup DSP cores. With four cards in the chassis, the change over unit
can support up to 1024 audio channels. The left side of the rear panel has four half-height
card slots. Dual power inlets for the two power supplies are 8HP (two slots) in height.
The two other slots are used for frame controller and chassis management connections.
