Keysight M9514A Site Preparation and Installation Guide 13
Plan the Chassis Installation Introduction
Chassis Ventilation
The chassis is designed to dissipate 200 W per module slot. Depending on load,
the chassis and power supply fans may exhaust significant heat. Operate in a
well ventilated (or air conditioned) environment. Allow 50 mm (2 in.) clearance on
both side of the chassis and 100 mm (4 in.) on the rear of the chassis.
AC Line Voltage Requirements
The M9514A comes prewired for a 3-phase Wye with Neutral configuration for
use with 220/380V, 230/400V, and 240/415C AC lines. Please consult Agilent
Support if you need otehr power entry configurations.
Acoustic considerations
Because of the volume of air that the chassis must move to adequately cool the
AXIe modules, the noise level around the chassis can exceed 79 dBA. You may
need to provide sound/noise mitigation in the room where the chassis/rack is
installed. Multiple chassis in a rack, plus the rack heat extractor fan noise, should
be considered. Ambient noise levels in the room may be reduced with:
- Dropped ceiling -- covered with a commercial grade of acoustic fiberglass
(flame-resistant) ceiling tile
- Sound deadening -- cover the walls with sound deadening material
- Removable partitions -- Use foam rubber models for most effectiveness.
Do not block the front fan air intake vent holes nor the fan exhaust
area on the chassis. This may overheat and damage components.
Avoid overloading an electrical circuit. Ensure your AC line matches
the AC Input requirements. If you need to power down the chassis
in an emergency, make sure that you have clear and quick access to
the primary disconnect. Refer to “Mains Disconnect” on page 22.
This chassis has an auto-ranging line voltage input, be sure the supply
voltage is within the specified range.
Hearing protection must be worn when working on or around the
chassis when it is powered on. The airflow noise around the chassis
can exceed 79 dB(A). This is outside the range that is normally
considered safe (70 dB(A)). Over and above that level is considered
hazardous and can result in permanent hearing damage.
