8-4 Installation and Troubleshooting Guide
This section is used for troubleshooting when the
shelf fault indicator
is lit and a hard-
disk drive is indicating a drive failure flash pattern. A PowerVault 660F or 224F
contains up to 14 Fibre Channel hard-disk drives.
All slots not occupied by a hard-disk drive must have a drive carrier blank panel to
ensure proper airflow. The blanks have no LED indicators. If a hard-disk drive’s status
is normal, either both green LEDs are on, or the right LED is on steadily while the left
ready
LED blinks as data is being accessed.
