I/O modules provide the input and output transfer of data. Failure of a single I/O module degrades connectivity and data availability. Failure of two I/O modules in the same Drive Enclosure results in data being unavailable on that Drive Enclosure and might affect the data availability of other Drive Enclosures on the same string. Replace a failed I/O module as soon as possible.
Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
Each Drive Enclosure has two I/O modules located at the back of the Drive Enclosure. I/O modules are customer replaceable units (CRUs). You can replace a failed I/O module without powering down the Drive Enclosure only if the other I/O module is operational with a status of Normal.
