Replaceable Parts Kit
The replaceable parts kit (X75SPR-KIT) includes the following items:
•2 fans
•4 stackers
• 1 power supply with no connectors
• 1 shaft encoder
Preparing for Installation
Prior to installing your system, you need to ensure certain environmental and electrical
conditions are met, and that frame support brackets are installed on the chassis.
Meeting Electrical Requirements
The X75 power supply has a universal input of 100-240 VAC at 47 to 63 Hz (nominal).
There is no voltage selector switch. Ensure that a proper power supply source is
available prior to operating your system.
Meeting Environmental Requirements
X75 frames are cooled by forced air drawn in from the front of the frame and exhausted
through vents at the rear. There must be free passage for air flow at the front and back of
the unit to allow for adequate ventilation. Take care to select a dry, well-ventilated
location with a minimum of dust.
Frames are designed for mounting in a standard 19-in. (48-cm) rack using standard
front-mounting ears and rear support brackets, and occupying a 1RU vertical space of
1.75 in. (4.4 cm). When installing a frame in a rack, ensure that there is adequate space
behind the mounting ears and clearance for the connecting cables at the rear of the
frame.
Tip: Maintain about 10 in. (25 cm) of slack in the rear connecting cables to allow for
frame access and maintenance while installed in the rack.
After unpacking the unit and before installing it into a console or rack, allow at least 30
minutes for temperatures to equalize and to eliminate any condensation that may have
developed. X75 frames require an ambient temperature of between 41° and 113°F (5° to
45°C), with a relative humidity of 10-90% (non condensing). The frame can only
maintain proper operating temperatures when the front panel is properly installed.
Caution
To ensure proper ventilation and
to prevent the frame from
overheating, keep the front
panel of a X75 frame closed.
