Replacing a 2-Port Ethernet iSCSI 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. CAUTION: • In dual-controller configurations, hot-add or hot-replace a controller or 2-Port Ethernet iSCSI 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 2-Port Ethernet iSCSI 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 SMU or MSA-CLI to disable the controller before removal. Verifying component failure Before replacing the 2-Port Ethernet iSCSI module: • Verify that the 2-Port Ethernet iSCSI module status LED is off or is flashing amber. • Check the array controller LCD display panel for error messages and take appropriate action. Removing the 2-Port Ethernet iSCSI I/O module CAUTION: Stop all system access to the module before proceeding with these replacement procedures. 1. Review all warnings, cautions, and preparation procedures as detailed in Warnings and precautions. 2. Disconnect the cable from the 2-Port Ethernet iSCSI module. 1510i Modular Smart Array maintenance and service guide 53

Replacing a 2-Port Ethernet iSCSI 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 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.
CAUTION:
•
In dual-controller con
fi
gurations, hot-add or hot-replace a controller or 2-Port Ethernet iSCSI 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 2-Port Ethernet iSCSI 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 SMU or MSA-CLI to disable the controller
before removal.
Verifying component failure
Before replacing the 2-Port Ethernet iSCSI module:
•
Verify that the 2-Port Ethernet iSCSI module status LED is off or is
fl
ashing amber.
•
Check the array controller LCD display panel for error messages and take appropriate action.
Removing the 2-Port Ethernet iSCSI I/O module
CAUTION:
Stop all system access to the module before proceeding with these replacement procedures.
1.
Review all warnings, cautions, and preparation procedures as detailed in
Warnings and precautions
.
2.
Disconnect the cable from the 2-Port Ethernet iSCSI module.
