Replacing a Fibre Channel I/O module 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. CAUTION: • In dual-controller configurations, hot-add or hot-replace a controller or Fibre Channel I/O module only during periods of low I/O. Hot-adding or hot-replacing these modules while under heavy I/O may cause a momentary pause, performance decrease, or loss of access to the MSA while the new controller is starting up. After the startup process is complete, full functionality will be restored. • In dual-controller configurations, the MSA controller and Fibre Channel I/O modules are hot-pluggable and the MSA does not need to be powered down during the replacement. However, you must first use an MSA management utility, such as the ACU or MSA-CLI to disable the controller before removal. Verifying component failure Before replacing the Fibre Channel I/O module: • Verify that the Fibre Channel I/O module Status LED is off or is blinking amber. • Verify that the 1-Gb link status is blinking amber. • Verify that the 2-Gb link status is blinking amber. • Check the array controller LCD display panel for error messages. Removing the component CAUTION: Stop all system access to the module before proceeding with these replacement procedures. maintenance and service guide 85

Replacing a Fibre Channel I/O module
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 air
fl
ow 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.
CAUTION:
•
In dual-controller con
fi
gurations, hot-add or hot-replace a controller or Fibre Channel I/O module
only during periods of low I/O. Hot-adding or hot-replacing these modules while under heavy I/O
may cause a momentary pause, performance decrease, or loss of access to the MSA while the new
controller is starting up. After the startup process is complete, full functionality will be restored.
•
In dual-controller con
fi
gurations, the MSA controller and Fibre Channel I/O modules are
hot-pluggable and the MSA does not need to be powered down during the replacement. However,
you must
fi
rst use an MSA management utility, such as the ACU or MSA-CLI to disable the controller
before removal.
Verifying component failure
Before replacing the Fibre Channel I/O module:
•
Verify that the Fibre Channel I/O module Status LED is off or is blinking amber.
•
Verify that the 1-Gb link status is blinking amber.
•
Verify that the 2-Gb link status is blinking amber.
•
Check the array controller LCD display panel for error messages.
Removing the component
CAUTION:
Stop all system access to the module before proceeding with these replacement procedures.
