Remove jewelry
— Prior to servicing, remove jewelry such as rings, watches,
and other metallic objects.
Avoid exposed circuitry
— Do not touch exposed connections, components or
circuitry when power is present.
Indicates that dangerous high voltage is present within the
equipment enclosure that may be of sufficient magnitude to
constitute a risk of electric shock.
Indicates that user, operator or service technician should
refer to product manual(s) for important operating, mainte-
nance, or service instructions.
This is a prompt to note fuse rating when replacing fuse(s).
The fuse referenced in the text must be replaced with one
having the ratings indicated.

connected to earth ground prior to making any other equip-
ment connections.
Identifies an external protective grounding terminal which
may be connected to earth ground as a supplement to an
internal grounding terminal.
Indicates that static sensitive components are present which
may be damaged by electrostatic discharge. Use anti-static
procedures, equipment and surfaces during servicing.

7500 Series Instruction Manual xi
Use proper power cord
— Use only the power cord supplied or specified for
this product.
Ground product
— Connect the grounding conductor of the power cord to
earth ground.
Operate only with covers and enclosure panels in place
— Do not operate this
product when covers or enclosure panels are removed.
Use correct fuse
— Use only the fuse type and rating specified for this
product.
Use only in dry environment — Do not operate in wet or damp conditions.
Use only in non-explosive environment
— Do not operate this product in an
explosive atmosphere.
High leakage current may be present
— Earth connection of product is essential
before connecting power.
Dual power supplies may be present
— Be certain to plug each power supply
cord into a separate branch circuit employing a separate service ground.
Disconnect both power supply cords prior to servicing.
Double pole neutral fusing
— Disconnect mains power prior to servicing.
Use proper lift points
— Do not use door latches to lift or move equipment.
Avoidmechanicalhazards
—Allow all rotating devices to come to a stop before
servicing.
Cautions
The following caution statements identify conditions or practices that can
result in damage to equipment or other property
Use correct power source
— Do not operate this product from a power source
that applies more than the voltage specified for the product.
Use correct voltage setting
— If this product lacks auto-ranging power sup-
plies, before applying power ensure that the each power supply is set to
match the power source.
Provide proper ventilation
— To prevent product overheating, provide equip-
ment ventilation in accordance with installation instructions.
Use anti-static procedures — Static sensitive components are present which
may be damaged by electrostatic discharge. Use anti-static procedures,
equipment and surfaces during servicing.

xii 7500 Series Instruction Manual
Do not operate with suspected equipment failure
— If you suspect product
damage or equipment failure, have the equipment inspected by qualified
service personnel.
Ensure mains disconnect
— If mains switch is not provided, the power cord(s)
of this equipment provide the means of disconnection. The socket outlet
must be installed near the equipment and must be easily accessible. Verify
that all mains power is disconnected before installing or removing power
supplies and/or options.
Routecableproperly
— Route power cords and other cables so that they ar not
likely to be damaged. Properly support heavy cable bundles to avoid con-
nector damage.
Use correct power supply cords
— Power cords for this equipment, if provided,
meet all North American electrical codes. Operation of this equipment at
voltages exceeding 130 VAC requires power supply cords which comply
with NEMA configurations. International power cords, if provided, have
the approval of the country of use.
Use correct replacement battery
— This product may contain batteries. To
reduce the risk of explosion, check polarity and replace only with the same
or equivalent type recommended by manufacturer. Dispose of used bat-
teries according to the manufacturer’s instructions.
Troubleshoot only to board level
— Circuit boards in this product are densely
populated with surface mount technology (SMT) components and applica-
tion specific integrated circuits (ASICS). As a result, circuit board repair at
the component level is very difficult in the field, if not impossible. For war-
ranty compliance, do not troubleshoot systems beyond the board level.

Regulatory Notices
Certifications and Compliances
FCC Emission Control
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equip-
ment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equip-
ment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own expense.
Changes or modifications not expressly approved by Grass Valley Group
can affect emission compliance and could void the user’s authority to
operate this equipment.
Canadian EMC Notice of Compliance

1-2 7500 Series Instruction Manual
Section 1 — Overview
The 7500WB frame is designed to switch signals from 10 Mbps to 1.485
Gbps. Figure 1-2 shows an example of Standard Definition (SD) and High
Definition (HD) signal routing using a 7500WB 256x256.

System Level Architecture
7500NB Architecture
7500NB AES Audio Systems are built around a 256x256, two bay, 12RU
matrix. The 7500NB 256x256 uses one matrix and the 7500NB 512x512 uses
two matrices connected together at the backplanes with expansion con-
nector modules. The 7500NB 1024x1024 uses eight matrices connected
together.
Matrices are populated with crosspoint modules, input modules, output
modules, and matrix controller modules. synchronous and asynchronous
input and output modules are available. Both types of modules can be
placed in the same matrix. The synchronous modules can be configured to
allow an asynchronous signal to be passed through an input or an output.
The two bay, 12RU matrix uses four input modules, four output modules,
and eight crosspoint modules for a fully configured 256x256 system. Each
bay of the system contains a slot for a matrix controller and a power supply.
The slot locations for the modules are shown in Figure 1-3. The empty slots
are used for crosspoint modules in expansion systems larger than 256x256.

System Level Architecture
Two of the two bay, 12RU matrices are connected using expansion connec-
tors to create a fully configured 512x512 system. The system uses eight
input modules, eight output modules, and thirty-two crosspoint modules
as shown in Figure 1-3. The top bay is always used for inputs 1-128, the
second one for inputs 129-256, the third for 255-384, and the fourth bay is
used for inputs 385-512.

Section 1 — Overview
Inputs are routed by the Crosspoint modules to the Output modules to
ensure that all Inputs are available to all Outputs. See Figure 1-4 for the
256x256 signal flow and Figure 1-5 for the 512x512 signal flow.
