M8xxx Fibre Channel Disk Drives
Each disk drive CRU has a part number/bar code label, a write-on label (for the logical
device name), and these indicator light-emitting diodes (LEDs):
•
Green power-on LED
When lit, the green power-on LED indicates that the disk drive is receiving power.
•
Yellow or amber activity LED
When lit, the yellow or amber activity LED indicates that the disk drive is executing
a read or write command.
These disk drives are Class-1 CRUs.
Any physical action on a CRU, including installing and replacing disks, can be
performed by customers. However, depending on the class of CRU, training in
replacement techniques might be recommended.
M8xxx Fibre Channel Disk Drives
M8xxx Fibre Channel disk drives are installed in Fibre Channel disk drive enclosures,
which can be connected to a NonStop S-series system through an IOAM. Figure 9-2
shows a single disk drive.
