Replacing a SCS

II/Omodule

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

withinoneortwominutes.Iftheinternaltemperatureexceedsacceptablelimits,thedevicemay

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.
