Replacing the SCSI I/O module CAUTION: The SCSI I/O module with an integrated EMU is not hot-pluggable. Before replacing the module, all I/O from the servers must be stopped and the MSA must be powered down. Before you begin CAUTION: • Before removing a component or blanking panel from an operational device, make sure that you have the replacement part available. Removing a component or blank impacts the airflow and cooling ability of the device. To avoid possible overheating, insert the new or replacement component within one or two minutes. If the internal temperature exceeds acceptable limits, the device may overheat and automatically shut down or restart. • Parts can be damaged by electrostatic discharge. Use proper anti-static protection. Verifying component failure Before replacing the SCSI I/O module: • Verify that the module status LED is not illuminated or is flashing amber. • Check the array controller LCD display panel for error messages and take appropriate action. Removing the component 1. Review all warnings, cautions, and preparation procedures as detailed in Warnings and precautions. NOTE: Before removing the SCSI I/O module, label all cables. This ensures their reconnection in the correct configuration. 2. Disconnect all SCSI cables from the SCSI I/O module. 3. Press down on the SCSI I/O module latch (1) and pull the SCSI I/O module out of the enclosure (2). 1 90 Customer replaceable components 2 1 5 559
