Hardware maintenance
2.1
Servicing
Other than a Lithium battery, there are no user serviceable parts inside the Prosody X
1U HA chassis. The unit may optionally be powered off for inspection every year and
to remove any dust that accumulates internally. This should only be performed by
qualified technical personnel.
2.1.1 Battery replacement
The internal battery is not re-chargeable and has a service expectancy of five years
under normal operating conditions. If the battery completely discharges, the system
will continue to operate, however time and date information will be lost when the unit
is turned off.
Please read the important safety information in Appendix E regarding battery
replacement.
2.2
Cooling fan failure
The Prosody X 1U HA chassis relies on forced air cooling to maintain the internal
electronics within rated operating temperatures. The unit has two field replaceable
"Hot swap" cooling fan assemblies, one front and one rear.
A cooling fan failure may be indicated by the openHPI software running on the
system.
System software monitors and controls the speed of all these fans. The fan speed will
vary as the temperature of the unit changes.
This should only be performed by qualified technical personnel.
