Mounting
The rack chassis is designed to t into any standard 19”equipment rack
enclosure. If used with the low prole ber yellobriks 1RU of rack space
is needed, if a taller yellobrik is to be accommodated then 3RU of space
will be required.
Chassis Use
Any yellobrik can be mounted into the chassis and secured rmly in
place with the mechanical mounting brackets provided. Power is taken
from the central power bus which plugs into the module. A space is
reserved on the right hand side to allow front side connection to pass
into the rear of the equipment rack for cable routing. Bracket use is
shown below:
External Power Connections
The chassis is equipped with two external power connectors, one for
primary power and a second for redundant power (if needed). The
connectors are located on the rear of the chassis. If supplying your own
power use a Molex MiniFit Series 5557 connector. Power should be
12VDC and between 5A and 10A should be available to accommodate
a full compliment of yellobriks. Connector wiring is shown below (view
is looking INTO the power connector on the chassis, and wiring for the
primary and redundant connectors is identical).
Insert module into rack.
Partially screw one of
the supplied brackets
into the mounting hole
(where shown). Position
the bracket to clamp
the module into place
and then tighten.
Module Power
The chassis has a integrated
central power bus, with a
connector provided for
each of the 14 slots.
Power Alarms
The chassis is equipped with external alarm GPO connections on the
front of the rack, as well as power present LED indication. In the event
of a supply failure the transition to the redundant backup is seamless,
and will trigger an external alarm GPO which can be connected to an
external alarm system. In the event of a power failure a contact
closure is provided across the connections shown below:
