For most components, the recommended maintenance is described in User's
Manuals provided with the unit. Refer to those documents for maintenance
procedures and frequencies to assure reliable, trouble-free operation.
All Preventive Maintenance is the responsibility of the customer.
Recommended frequency is every 6 months, or less in harsh environments.
Two areas of maintenance deserve special mention -- cleaning air intakes of
workstations and the server and regular replacement of UPS batteries.
Fans used to cool electronic devices generally develop dust build-up in air intake
areas that must be removed to assure proper cooling and circuit operation. Air
intakes of workstations and the server should be checked regularly and any dust
buildup removed. Status/error messages on Main Screens, LED displays, and LCD
front panel displays and entries in device Event Logs may also alert the customer to
these conditions.
The UPS requires little maintenance other than regular battery replacement. It also
contains no serviceable parts except the battery and should not be opened by hospital
personnel because it contains potentially hazardous voltages that can be dangerous to
unskilled persons.
Do not attempt to disassemble the UPS. It contains no serviceable parts except
for the battery, and interior voltages can be hazardous. Repair should be
performed by factory trained service personnel only.
Regular testing of the UPS is not generally required because it is tested during any
emergency power system test. However, a simple reliability test is given in Chapter
8, under Power Failure Response Test.
To assure dependable UPS performance, regular replacement of UPS batteries is
recommended. The replacement frequency depends somewhat on the environmental
conditions experienced by the UPS.
