CHAPTER 1
Overview
The Avid MediaDock 2+ houses two LVD shuttles and an optional
DVD writer. The shuttles make it easy to share media (or data files)
between systems without connecting or reconnecting cables. The
MediaDock 2+ shuttles communicate with the Avid editing system
through a small computer system interface (SCSI) bus. The LVD
shuttles contain an industry-standard SCSI drive that is optimized for
use with Avid’s video and audio applications. The optional DVD
writer communicates with the Avid editing system via IEEE 1394
(FireWire).
nAs drive size and performance improve, different LVD shuttles will be
available for use. Contact your local Avid Reseller or call the Avid Sales and
Product information line at 800-949-2843 for the latest information about
available drives.
The MediaDock 2+ enclosure is designed as a desktop unit as well as
for mounting in industry-standard, 19-inch racks. Multiple
MediaDock 2+ enclosures can be stacked on top of one another,
minimizing the amount of desk space required.
LVD shuttles can be formatted for Windows or Macintosh operating
systems. Windows operating systems use the Windows Disk
Management utilities in the Windows operating system. For details,
see Chapter 3 of this guide and your Windows operating system
documentation.

16
Macintosh operating systems use the AVIDdrive™Utility 2 software to
manage shuttle packs (LVD shuttles) within your Avid editing system.
nFor information on using AVIDdrive Utility 2, see the AVIDdrive Utility 2
User’s Guide and the release notes for Media Composer Release 8.0 or later.

MediaDock 2+ Enclosure Features
The MediaDock 2+ enclosure contains:
• Two shuttle slots that support:
-LVDSCSIoperation
- Wide bus data transfers over a 16-bit bus up to 160 MB/s
(depending on the type of hard disks configured on the SCSI
bus and the type of host bus adapter)
- One LVD shuttle per slot containing a single 1.0-inch- or
1.6-inch-high hard disk in a 3.5-inch form factor
• One slot available for an optional DVD writer
• Single power supply
• Front-mounted SCSI ID selection switches
• LEDs to monitor MediaDock 2+ enclosure’s power and
temperature as well as shuttle functions
• Variable-speed, temperature-sensing fan

MediaDock 2+ Enclosure Slots
The MediaDock 2+ enclosure has two slots for LVD shuttles (see
Figure 1-1). This guide illustrates the MediaDock 2+ enclosure
without any device in the optional device bay. For instructions on
installing a DVD writer in the optional device bay, see Chapter 4.
nThe LVD shuttles are sold separately, see “LVD Shuttle Features” on
page 20.

Front Panel
The front of the Avid MediaDock 2+ has controls and indicators for
determining its operating status (see Figure 1-2).
The front panel power switch turns the drive’s internal power supply
on and off. Two light emitting diodes (LEDs) provide the status of the
unit. The SCSI ID switches provide the method for setting the drive
shuttle’s SCSI IDs. The label on the right side of the front panel is the
Avid product identification label.

Back Panel
The MediaDock 2+ back panel has two SCSI connectors and a power
connector (see Figure 1-3). The SCSI connectors are for attaching SCSI
cables or a SCSI terminator to the drives. An internal fan pushes air
through the enclosure, from front to back, to cool the drive. The power
connector is where you attach the power cord. The optional device
connector panel contains IEEE 1394 (FireWire) connectors when an
optional DVD writer is installed. See Chapter 4 for more information.

Thermal LED
c
The LED (red) flashes when the thermal overload
circuitry senses that the temperature inside the
MediaDock 2+ is too high. The LED could light for
the following reasons:
• Airflow through the drive is blocked.
• The internal fan has failed.
• Room ambient temperature is too hot.
Operating the MediaDock 2+ for extended
periods of time with the thermal indicator
on reduces the life expectancy of the drives.

Power Supply
The power supply in the MediaDock 2+ enclosure supplies power to
both LVD shuttles and the optional device bay.
The power supply has two LEDs that are visible on the front of the
chassis beside the power switch. The green LED is On when power is
on and within specifications. The red LED is On when a thermal fault
is detected. Figure 1-2 shows the power switch and LED locations on
the MediaDock 2+ enclosure. Descriptions of the LEDs are provided in
Tab le 1 -1.
LVD Shuttle Features
The MediaDock 2+ enclosure uses only LVD shuttles. These shuttles
are not included with the MediaDock 2+ enclosure, and must be
purchased and installed separately. The LVD shuttles are available in a
variety of storage capacities.
The LVD shuttles use a lever for inserting or removing the LVD shuttle
from the MediaDock 2+ enclosure. The internal drives have a 3.5-inch
form factor and transfer data on a 16-bit data bus. The drive enclosure
provides the cooling, power, and cabling connections.
Each LVD shuttle contains two LEDs that provide information about
the LVD shuttle’s activity (see Figure 1-4). Tab le 1 -2 describes the
function of each LED. The third LED is not used in the MediaDock 2+.
