Faults
Edge Connector Contacts
Despite the gold plating of edge connector contacts they may collect dust
and grease which can degrade the contact. When you remove a module
check that the fingers are clean, free of grease and undamaged. If necessary
clean the fingers with a clean cloth and a solvent-based cleaner such as
alcohol. Take care not to get the solvent on plastic parts as it can cause
damage. Avoid touching the clean edge connector contacts with your
fingers.
Configuration
Check that the equipment is correctly configured including any hardware
jumpers. Refer to Section 2: Installation.
