11 Chassis Maintenance
No periodic maintenance of the chassis is required. However, Keysight
recommends monitoring the Primary Power Module (PPM) voltage rails, the
chassis fan speeds, and the chassis firmware at least yearly:
– Power supply voltages — All PPM voltages should all be within ±5% of their
nominal values. The PPM rails are accessible on the rear panel DB-9
connector. See “Measuring the Main Voltage Rails Directly” on page 54.
–Fan speeds — A low chassis fan speed possibly indicates that a fan is
wearing out or a fan blade is partially obstructed. See “Monitoring Chassis
Fan Speeds” on page 67.
– Chassis firmware — Keysight recommends that you periodically check to see
if there is a chassis firmware revision available that is later than your
current chassis firmware revision. If so, you should download and install
the latest firmware revision available as described in “Updating Chassis
Firmware” on page 141.
If a power supply voltage is out of tolerance or a fan speed is low, see the
Keysight PXIe Family Chassis Service Guide for diagnostic information.
These chassis are Safety Class 1 products (provided with a
protective earthing ground incorporated in the power cord).
The mains plug shall only be inserted in a socket outlet
provided with a protective earth contact. Any interruption
of the protective conductor inside or outside of the product
is likely to make the product dangerous. Intentional
interruption is prohibited. Inspect the protective conductor
periodically to ensure that it is uninterrupted.
- No operator serviceable parts inside. Refer servicing to
qualified personnel.
- To prevent electrical shock, do not remove covers.
- To prevent electrical shock, disconnect the chassis
power cord before cleaning. Use a dry cloth or one
slightly dampened with water to clean the external case
parts. Do not attempt to clean internally.
- Cleaning connectors with alcohol shall only be done with
the chassis power cord removed and in a well-ventilated
area. Allow all residual alcohol moisture to evaporate,
and fumes to dissipate prior to energizing the chassis.
