Chapter 2
Installation
This chapter describes how to install a VideoRAID RTR320X array into a rack and how to attach the rubber feet to the bottom of the VideoRAID when using it as a desktop or deskside array. Completely unpack the VideoRAID and check the contents of the VideoRAID box
against the items identified in “Box Contents” on page 6 .
VideoRAID array components includes:
• Five or ten drive carriers (shipped separately)
• One or two power supply modules
• One or two SCSI controllers
• One or two EMI Shields
You are required to purchase the SCSI cables for you configurations. Avid offers several
SCSI cables for connecting the array to your Avid system, see
“Ultra320 SCSI Cables
Available Through Avid” on page 22 . You can connect the array to either a Windows-based
or Macintosh-based Avid system. The VideoRAID array is supported only on Avid systems that have Ultra320 SCSI adapters.
VideoRAID Desktop and Deskside Configurations
VideoRAID RTR320X can be set up in a desktop (horizontal), deskside (vertical), or rack-mount configuration. If you are rack-mounting the VideoRAID RTR320X, see
“Installing Rack-Mount Enclosure” on page 16 .
n
The VideoRAID RTR320 comes with the rubber feet already installed on the enclosure. This enclosure is ready for you to install the drives, see
“Installing the Drives” on page 19
.
To set up your VideoRAID RTR320X as a desktop or deskside enclosure:
1. Locate the four screw-on feet that are included in the VideoRAID RTR320X kit.
2. Replace the four screws on the bottom or side of the enclosure with the four screw-on feet as shown in the following figure.
Chapter 2 Installation
Attaching the Feet for the Desktop Configuration (Bottom View)
Installing Rack-Mount Enclosure
The VideoRAID RTR320X enclosure is designed for 19-inch (483-mm) rack enclosures and requires three EIA rack units (3U), or 5.25 inches (133.4-mm) of rack space. The
VideoRAID RTR320X ships with brackets, and bracket screws. You need to supply your own rack fasteners. w
To ensure the stability of the rack enclosure, start from the bottom when you install the rack components in the rack enclosure.
Rack-mount Requirements:
• Elevated Operating Ambient — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment might be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
• Reduced Air Flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
VideoRAID airflow is from the rear of the chassis enclosure to the front. Make allowances for cooling air to be available to the front panel surface and no restrictions at the rear.
• Mechanical Loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
Make sure your rack enclosure is stable enough to prevent tipping over.
• Circuit Overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
16
Installing Rack-Mount Enclosure
• Reliable Earthing — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (for example, use of power strips).
Attaching the Rack-Mount Brackets on the VideoRAID RTR320X
Rack-mounting brackets are included with the VideoRAID RTR320X. n
Do not install the drives into the rack enclosure until you have installed the enclosure into the rack. When the drives are in the enclosure, the enclosure is heavy and difficult to handle.
To attach the rack-mount brackets:
1. Locate the rack-mounting brackets that are included in the VideoRAID RTR320X kit and establish the left and right sides by locating the bracket with the rectangle cut-out
(see the following figure.

2. Align the holes in the VideoRAID RTR320X with the holes in the front mounting rail.
From the front of the rack enclosure, insert the screws through the VideoRAID
RTR320X and front mounting rail, and tighten.
Installing the Drives
The drives are not installed in the VideoRAID enclosures and are shipped separately. You must install a set of five drives to complete a RAID set. The VideoRAID RTR320X enclosure can have five or ten drives installed. The drives are mounted in drive carriers that fit into either model enclosure.
19
Chapter 2 Installation c
If you are using the VideoRAID RTR320X in a deskside configuration and are only installing five drives, they must be installed in the bottom half of the VideoRAID array.
Installing drives in the top half of the array without any drives in the bottom half greatly increases the chances of the VideoRAID falling over.
To install the VideoRAID drives in the enclosure:
1. Power off the VideoRAID.
2. (Option) If you are adding drives to a VideoRAID RTR320X that is already in use, remove the EMI shield covering the empty slots on the VideoRAID RTR320X. For
more information on the EMI shield, see “Installing the EMI Shields” on page 20
.
3. Open the new drive by sliding the indentation in the drive carrier in the direction of the arrow (to the outer edge). The drive carrier lever releases.

4. Insert the drive carrier in one of open carrier slots in the VideoRAID enclosure until it engages the lever.
5. Lock the drive carrier into the enclosure by pushing the drive carrier lever so that it snaps back in place.
For instruction on turning on the configuring the RAID set, see “Initializing the
VideoRAID” on page 30
.
Installing the EMI Shields
In order for your VideoRAID disk array to meet emission compliance, the metal shield(s) included with the unit must be installed. Please follow the instructions below to install.
20
Cabling the VideoRAID
To install the EMI shields:
1. Locate the EMI shield(s) included with your VideoRAID.
2. Position the shield so that the side without metal springs is toward the power supply.
3. Insert the bottom of the shield in the gap under the bottom most disk drive on the rear of
VideoRAID.
4. Press the shield(s) in to place.
5. If you have the VideoRAID 320X model, repeat these steps to install the second shield over the other drive set.

Daisy Chaining the VideoRAID
You can attach one or two VideoRAID RTR320 arrays on one Ultra320 SCSI channel. One
VideoRAID RTR320X enclosure (two arrays in a full enclosure with ten drives) can have both arrays on a single Ultra320 SCSI channel. If your workstation has two Ultra320 SCSI channels, then you could have four arrays per workstation or two arrays per Ultra320 SCSI channel. To use two arrays on a single Ultra320 SCSI channel, you must daisy chain the two arrays.
23
Chapter 2 Installation
To daisy chain VideoRAID arrays:
1. Make sure the power if off on both the Avid system and VideoRAID array.
2. Locate two Ultra320 SCSI cables.
For available SCSI cables, see
“Ultra320 SCSI Cables Available Through Avid” on page 22 .
3. (Option) If you previously were using a single VideoRAID array, remove the SCSI terminator from the SCSI connector on the rear of the enclosure.
4. Attach one end of the SCSI cable to either SCSI connector on the Avid system. Secure the cable connector with the thumbscrews on the connector.
n
You might need the workstation documentation that came with your Avid system to help locate the appropriate SCSI connector on the system.
5. Attach the connector on the other end of the SCSI cable to the left (or bottom) SCSI connector on the rear of the first VideoRAID. Secure the cable connector with the thumbscrews on the connector.
6. Attach a second SCSI cable to the second (right) connector on the first VideoRAID.
Secure the cable connector with the thumbscrews on the connector.
7. Attach other end of the second SCSI cable to the left SCSI connectors on the rear of the next VideoRAID array.

This is the maximum supported configuration.
Connecting the Power Cord
To connect the power cord to the enclosure:
1. Locate the power cord in the VideoRAID kit.
The Video RAID RTR320X includes two power cords. Even if you don’t have both halves of the VideoRAID RTR320X filled with drives, you can still power on the empty side of the VideoRAID RTR320X array for power redundancy. For more information, see
“Power Supply Status Indicators” on page 12
.
2. Plug the power cord into the power connector on the rear of the enclosure.
3. Plug the power cord into a power outlet.

Setting the SCSI ID
For each VideoRAID set you connect to the Windows or Macintosh operating system, you must assign a SCSI ID so the system can find and access the SCSI device. When you are setting the SCSI IDs, consider the following:
• Each VideoRAID drive set on the SCSI bus has its own set of unique SCSI IDs from
0 through 6 and 8 through 15.
• You cannot have two SCSI drives with the same SCSI ID on the same SCSI bus.
26
Setting the SCSI ID c
You cannot have more than two VideoRAID drive sets on any one SCSI bus and no other SCSI devices are supported on the SCSI bus with the VideoRAID.
n
You must set unique SCSI ID numbers on both halves of a fully populated VideoRAID
RTR320X array.
To set the SCSI ID:
1. Turn the SCSI ID selector dial so that the dot on the dial is beside the number you want for your SCSI ID number.
In the following figure, the dot on the SCSI ID selector is set to SCSI ID 6.
c
You cannot use SCSI ID 7, that is reserved for the host.
2. Power cycle the VideoRAID array to make sure the new SCSI ID is activated.
