About Removable Media Devices

The Sun Fire V890 system provides front-panel access to three mounting bays. One
bay houses an IDE DVD-ROM drive, which comes standard in all system
configurations. The other two bays can house optional wide (68-pin) SCSI removable
devices, which must be ordered separately. The tape drive option also requires a
SCSI cable and a SCSI adapter card; both must be ordered separately. You can easily
convert the two SCSI device bays into a single full-height bay by removing a metal
shelf divider.
The SCSI bus that supports the removable media devices is Fast/Wide-capable
(20 Mbytes per second) and can support single-ended, wide or narrow SCSI devices.
Target addresses (also know as SCSI IDs) for the SCSI bus are available in the ranges
of 0 through 5 and 8 through 15.
The target address reserved for the optional tape drive is 5.
If no tape drive is installed, you can use this address for an external device. If you
later install an internal tape drive, you must use 5 as its address and assign a
different address to the external device.
Caution – All internal options (except disk drives and power supplies) must be
installed only by qualified service personnel.
