Installing the component

1. Slide the replacement SCSI I/O module into the bay until it clicks into place.
2. Reconnect all SCSI cables.
NOTE:
Ensure that all of the SCSI cable connectors are fastened tightly.

Verifying proper operation

After replacing the failed SCSI I/O module, verify that:
• The module status LED is solid green.
• No new error messages are displayed on the array controller LCD panel.

Replacing the power button module

CAUTION:
The power button 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.

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.
