Service Inspection Guide

Perform a service inspection on the system (processor subsystem and connected I/O
subsystems) when:
v The system is inspected for a maintenance agreement.
v Service is requested and service has not recently been performed.
v An alterations and attachments review is performed.
v Changes have been made to the equipment that may affect the safe operation of the
equipment.
v External devices with their own power cables have those cables attached.
If the inspection indicates an unacceptable safety condition, the condition must be
corrected before anyone can service the machine.
Note: The owner of the system is responsible to correct any unsafe conditions.
Perform the following checks:
1. Check the covers for sharp edges and for damage or alterations that expose the
internal parts of the system.
2. Check the covers for proper fit to the system. They should be in place and secure.
3. Gently rock the system from side to side to determine if it is steady.
4. Set the power button of the system to Off.
5. Remove the covers.
6. Check for alterations or attachments. If there are any, check for obvious safety
hazards, such as broken wires, sharp edges, or broken insulation.
7. Check the internal cables for damage.
8. Check for dirt, water, and any other contamination within the system.
9. Check the voltage label on the back of the system to ensure that it matches the
voltage at the outlet.
10. Check the external power cable for damage.
11. With the external power cable connected to the system, check for 0.1 ohm or less
resistance between the ground lug on the external power cable plug and the metal
frame.
12. Perform the following checks on each device that has its own power cables:
a. Check for damage to the power cable.
b. Check for the correctly grounded power cable.
c. With the external power cable connected to the device, check for 0.1 ohm or
13. Install the covers.
