3-6 Sun StorEdge D240 Media Tray Installation, Operation, and Service Manual • August 2001
3.3 SCSI Host Connection Requirement
The media tray must be connected to a separate SCSI adapter configured on the host.
Caution – The media tray has fixed disk addresses that may conflict with system
device addresses. Do not connect the media tray to a host system board or to a SCSI
controller board that has internal disks.
3.4 Powering On or Off and Booting the
Host System
The media tray does not have its own power on-and-off switch. To apply AC power,
connect the power cord on each power supply to an AC power source. To remove
AC input voltage, remove the power cord from each power supply.

Caution – You must make the SCSI bus quiescent before removing power from the
media tray. Failure to do this can result in loss of data. See the Solaris Handbook for
Sun Peripherals appropriate to your version of the Solaris operating environment for
the software procedure to perform.
