2.0 Matrix-Hub Components
Each Series 1000 chassis consists of a metal enclosure, an electroluminescent
display, cooling fans, redundant power supplies with separate AC inputs, a
control card, three switch cards, and the user-specified signal input and output
cards.
The chassis is rack-mountable using the flanges on the front of the unit. If the
unit is to be rack-mounted, it is recommended that the rear of the unit is
supported within the rack using support brackets (available from Lightwave), and
allowance is made for adequate ventilation through the unit. The chassis may
also be used as a stand-alone unit, and is shipped with rubber feet attached to
allow airflow through the bottom of the unit when placed on a surface.
The electroluminescent front panel display allows access to the Matrix-Hub’s
internal diagnostic and connection displays (see section 7.0, Electroluminescent
Display).
The Series 1000 has redundant power supplies with separate AC inputs. Each
power supply is a set of two individual power supplies that provides separate
+5VDC and –5VDC. In ordinary operation, the two power supply sets share the
electrical current load equally. However, when one set fails, the other set can
provide all power for the unit. If the separate AC inputs are connected to
different AC sources, then the Matrix-Hub will not fail if one AC source fails. The
power supplies report their status through the front panel display and through the
user interface.
