2. Rackmounting and Hardware Overview
This chapter describes the VBOB hardware. The first section shows you how to mount
the VBOB unit in a rack, and the following sections explain the theory of operation.
Mounting VBOB in an SGI 3000 Series Rack
You can install the VBOB chassis as a free-standing table-top unit, or mount it in a rack.
This section explains how to install the VBOB chassis in an SGI 3000 series rack. Before
you begin, make sure that you have the hardware listed in Table 2-1.
Warning: Personnel could be seriously injured and equipment could be damaged if
the rack topples over. Install all equipment into the rack from the lowest available
position. Also, make certain that the rack has sufficient power for the VBOB’s needs.
Check with the appropriate facilities authorities before installing this unit in a rack.
Note: This installation requires two people and a #2 Phillips screwdriver.
This procedure presumes that internal rackmounting rails are already installed and that
a vertical space of 3.5 in. (8.9 cm) is available.

2: Rackmounting and Hardware Overview
Theory of Operation
VBOB is a digital video switcher that routes video inputs from different sources to
various output formats.VBOB inputs include Serial Digital Standard Definition (SD) and
High Definition (HD) BNC connectors, a Low Voltage Differential Signaling (LVDS)
video input connector, and an optional dual-link Transition Minimized Differential
Signaling (TMDS) input. VBOB outputs include dual-link Serial Digital Standard
Definition and High Definition BNC connectors, which you can use with applications
where Alpha signals accompany the YUV video. In addition, VBOB includes an LVDS
video output connector. Generator Locking Device (Genlock) input and loop-throughs
for both Standard Definition Video and High Definition Video, and a RS-232 port for
system upgrading and maintenance are also included.
Utilizing a highly advanced 80-bit parallel video crossbar, you can configure VBOB for
various I/O applications. VBOB complies with the following standards:
• High Definition SMPTE-292M
• Standard Definition SMPTE-259M
Note: HD and SD have separate connections, which allows you to switch between
operational domains without switching cables.
8 007-4243-002
LVDS Interface
Genlock
Theory of Operation
LVDS is a new data interface standard that is defined in the TIA/EIA-644 and the IEEE
1596.3 standards. It transmits data at a high speed using a very low voltage swing
(approximately 350mV) over two differential circuit board traces or a balanced cable. The
LVDS drivers are current mode, so a termination resistor is required to complete the
current loop and limit reflections due to the sub-nanosecond transition times over the
transmission line.
Genlock is a device that enables VBOB to receive an external sync signal, which locks the
timing of the output video picture. This allows you to maintain a common timing across
multiple video devices, which enables smooth dissolves, wipes, and other effects
commonly used onbroadcast TV. VBOB has two BNC connectors for Standard Definition
genlock and twoBNC connectors for High Definition genlock. You can use either of these
connectors as an input or a loop-through.
TMDS Interface (optional)
TMDS is the basis of the Digital Visual Interface (DVI) standard, which transmits data
using a differential interface with the data transitions minimized over a balanced cable.
Note: The TMDS Interface is optional. It is sometimes included as standard equipment
when VBOB is purchased with TMDS-related products, such as HD GVO.

If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Caution: Users should note that changes or modifications to the equipment not
expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.

A: Regulatory Specifications
Radio and Television Interference
The equipment described in this guide generates and uses radio frequency energy. If it is
not installedand used in accordance with the instructions inthis guide, it can cause radio
and television interference.
This equipment has been tested and complies with the limits for a Class A computing
device in accordance with the specifications in Part 15 of FCC rules. These specifications
are designed to provide reasonable protection against such interference in an industrial
or office installation. However, there is no guarantee that the interference will not occur
in a particular installation. This system is not certified for home use.
You can determine whether your system is causing interference by turning it off. If the
interference stops, it was probably caused by the workstation or one of the peripherals.
To tell if the interference is caused by one of the peripherals, try disconnecting one
peripheral at a time to see if the interference stops. If it does, that peripheral is the cause
of the interference.
If your workstation does cause interference to radio or television reception, try to correct
the interference by following one or more of these suggestions:
• Turn the television or radio antenna until the interference stops.
• Move the workstation to one side or the other of the radio or television.
• Move the workstation farther away from the radio or television.
• Plug the workstation into an outlet that is on a different circuit from the radio or
television. (That is, make certain the workstation and the radio or television are on
circuits controlled by different circuit breakers or fuses.)
• For additional information, see the FCC Web site at
http://www.fcc.gov/cib/Publications/tvibook.html
Shielded Cables
The device isFCC-compliant under test conditions that include the use of shielded cables
between the workstation and its peripherals. Your workstation and any peripherals you
purchase from Silicon Graphics have shielded cables. Shielded cables reduce the
possibility of interference with radio, television, and other devices. If you use any cables
that are not from Silicon Graphics, be sure they are shielded. Telephone cables do not
need to be shielded.
20 007-4243-002
Electrostatic Discharge
Silicon Graphics designs and tests its products to be immune to the effects of electrostatic
discharge (ESD). ESD is a source of electromagnetic interference and can cause problems
ranging from data errors and lockups to permanent component damage.
Note: While operating your workstation, keep all covers and doors, including the
plastics, in place. The shielded cables included with the workstation and its peripherals
should be installed correctly, with all thumbscrews fastened securely.
An ESD wrist strap is included with some products, such as memory and graphics
upgrades. The wrist strap is used when installing these upgrades to prevent the flow of
static electricity, and it should protect your system from ESD damage.
