1.9. Installation
The Cortex CRT is a standard 19" rack mount equipment.
The equipment must be installed in a 19" cabinet.
The installation must follow the following guidelines:
Use a 19" cabinet of 600mm depth or more.
Use of open-front cabinets is preferable. If the cabinet has a closed front door, make sure that
sufficient airflow is forced into the cabinet from the floor up.
Use L-shaped brackets in the 19" cabinet to sustain the weight of the equipment. L-shaped brackets
model depends upon the cabinet manufacturer. Please contact your 19" cabinet vendor for proper L
shaped bracket selection.
If you wish to use sliding rails, make sure that the 19" cabinet has enough stability to avoid falling
forward when the Cortex CRT is pulled out. The following sliding rails can be used: for chassis 4U,
Schroff, model 20110-094; for chassis 2U, GHA-SL20.
For 4U chassis, the airflow in the Cortex CRT is from the sides and top to the back of the unit.
Assign at least 1U of free space above the Cortex CRT unit for proper cooling. For 2U chassis, the
airflow is from the front and sides to the back of the unit. While it is recommended to keep 1U of free
space above the Cortex CRT unit when using L-shaped brackets in order to prevent any scratch on
the cover, it is not necessary when using slide rails.
In the front of the 19" cabinet, preferably use a 1U blanking plate with a grid to allow the airflow into
the Cortex CRT unit from the front of the cabinet.
Place an extractor fan unit at the top of the 19" cabinet. Place it at the rear end of the cabinet rather
than the front end to extract the warm air that may accumulate at the rear of the Cortex CRT units.
For 4U chassis, remove the keyboard drawer retaining screws (refer to the sticker on the side of
the unit) and keep these screws for future shipments.
Use 4 bolts to secure the Cortex CRT unit to the 19" cabinet, using the 2 holes on each side of the
front panel. Bolts and captive nuts are supplied by your 19" cabinet vendor. Make sure that the bolts
are long enough to reach the nuts in the 19" cabinet rails
Connect the Cortex CRT to an AC power supply socket equipped with proper grounding
If additional grounding is desired, use the grounding bolt and nut located at the lower left corner at
the rear of the Cortex CRT unit and connect to the closest grounding point in the 19" cabinet, using
a copper wire or preferably a grounding braid.
For Cortex CRT models supplied with an external interconnexion panel, place the BNC
interconnection panel at the back of the 19" cabinet, such that you have an easy access to the
connectors for maintenance purposes. Make sure that the cables between the BNC panel and the
rear connectors on the unit shall not be accidentally disconnected when an equipment is pulled
forward or when personnel has to reach the rear of an equipment inside the 19" cabinet
