Prosody X Installation guide

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.
