Installation Guidelines
Ensure the rack is mounted in a clean, dry environment with adequate ventilation to prevent overheating.
Always power down the system before inserting or removing any modules from the backplane to prevent electrical damage.
Ensure the chassis is properly grounded to the cabinet frame to mitigate electromagnetic interference (EMI).
Verify that the external power supply rails are correctly wired to the backplane before energizing the system.
Handle modules with care to avoid electrostatic discharge (ESD) damage to sensitive backplane pins.
FAQ
