Replacing a SCSI I/O module Before you begin CAUTION: • Before removing a component or blank from an operational device, make sure that you have the replacement part or blank available. Removing a component or blank impacts the airflow pattern and cooling ability of the device. Allow approximately 30 seconds before installing the new or replacement component to ensure that configuration data about the removed component is cleared from the system registry, but, 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 off or is blinking amber. • Check the array controller LCD display panel for error messages. Removing the SCSI I/O module CAUTION: The SCSI I/O module is not hot-pluggable. Before replacing the module, all I/O from the servers must be stopped and the MSA must be powered down. 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. 1510i Modular Smart Array maintenance and service guide 57

Before you begin
CAUTION:
•
Before removing a component or blank from an operational device, make sure that you have the
replacement part or blank available. Removing a component or blank impacts the air
fl
ow pattern
and cooling ability of the device. Allow approximately 30 seconds before installing the new or
replacement component to ensure that con
fi
guration data about the removed component is cleared
from the system registry, but, 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 off or is blinking amber.
•
Check the array controller LCD display panel for error messages.
