2.5 Replacement and Spares
Replacement parts may contain static-sensitive components. Therefore, GE ships replacement parts in anti-static bags. When
handling electronics, make sure to store them in anti-static bags or boxes and use a grounding strap.
Caution
To prevent component damage caused by static electricity, treat all boards with static-
sensitive handling techniques. Wear a wrist grounding strap when handling boards or
components, but only after boards or components have been removed from
potentially energized equipment and are at a normally grounded workstation.
Warning
In addition to information provided here, always follow all wiring and safety codes
that apply to your area or your type of equipment. For example, in the United States,
most areas have adopted the National Electrical Code standard and specify that all
wiring conform to its requirements. In other countries, different codes will apply. For
maximum safety to personnel and property you must follow these codes. Failure to do
so can lead to personal injury or death, property damage or destruction, or both.
2.5.1 Replacement Procedure
System troubleshooting should be at the module level. The failed module should be removed and replaced with a known good
spare. The failed device should be returned to GE for repair. Do not attempt to repair it on site.
Caution
To prevent equipment damage, do not remove, insert, or adjust board connections
while power is applied to the equipment.
To replace the MFA
1. Lock Out Tag Out (LOTO) the equipment to isolate power sources.
2. Disconnect the incoming power plug.
3. Disconnect the Ethernet cables.
4. Remove the screws holding the MFA in place.
5. Install the new MFA by reversing steps 4 through 1.
