Note: 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 equipment 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 equipment 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.

Caution: Any changes or modications made by the user that are not expressly approved

by Euphonix could void the user’s right to operate the equipment.

IMPORTANT SAFETY INSTRUCTIONS

The lighting ash with arrowhead symbol within an equilateral triangle, is

intended to alert the user to the presence of uninsulated “dangerous voltage”

within the product’s enclosure that may be of sufcient magnitude to constitute a

risk of electrical shock to persons.

The exclamation point within an equilateral triangle, is intended to alert the user

to the presence of important operating and maintenance (servicing) instructions
in the literature accompanying the product.

Read these instructions.1)

Keep these instructions.2)

Heed all warnings.3)

Follow all instructions.4)

Do not use this apparatus near water.5)

Clean only with a dry cloth.6)

Do not block any ventilation openings. Install in accordance with the manufacturer’s 7)
instructions.

Do not install near any heat sources such as radiators, heat registers, stoves, or other 8)

apparatus (including ampliers) that produce heat.

Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug 9)
has two blades with one wider than the other. A grounding type plug has two blades and a
third grounding prong. The wider blade or the third prong are provided for your safety. If

the provided plug does not t into your outlet, consult an electrician for replacement of the

Use only with the cart, stand, tripod, bracket, or table specied by the manufacturer, or 12)

sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus
combination to avoid injury from tip-over.

Unplug this apparatus during lightning storms or when unused for long periods of time.13)

Refer all servicing to qualied service personnel. Servicing is required when the apparatus 14)
has been damaged in any way, such as power-supply cord or plug is damaged, liquid has

been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain
or moisture, does not operate normally, or has been dropped.

WARNING – TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT 15)
EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.

Do not expose this equipment to dripping or splashing and ensure that no objects lled with 16)
liquids, such as vases, are placed on the equipment.

To completely disconnect this equipment from the AC Mains, disconnect the power supply 17)

cord plug from the AC receptacle.

The mains plug of the power supply cord shall remain readily operable.18)

This unit is provided with a power supply cord set suitable for 120V AC input only (for 19)

U.S.A. and Canada). For other than U.S.A. and Canada, a qualied person must provide for

use with this unit, an appropriate, approved power supply cord set which is in compliance

with the end use country requirements and has a minimum cross-sectional area of 1.0mm².

For units with more than one power cord:20)

Caution: This unit has more than one power supply cord. Disconnect two power

supply cords before servicing to avoid electrical shock.

Attention: Cet appareil comporte plus d’un cordon d’alimentation. An de prévenir les

chocs électriques, débrancher les deux cordons d’alimentation avant de faire
le dépannage.

Operator Accessible Fuse:21)

Caution: For continued protection against risk of re, replace only with same type and

rating of fuse.

Attention: Pour ne pas compromettre la protection contre les risques d’incendie,

remplacer par un fusible de même type et de même caractéristiques

nominales.

Important Note!

Due to the “Hot Swap” capabilities of all card components in the COS chassis, power can be
applied to the unit at any time before after or during card installation. It is recommended,
however, that this feature only be used when necessary.

This is because the hot swap system can not protect from all possible errors made by the
operator during card installation.

Powered on cards are susceptible to damage from accidental shorting due to conductive

jewelry, excessive card deection, or mis-aligned insertion or cards. To insert or remove
cards while the chassis power is applied, rst carefully read instructions in this manual to

prevent damage to equipment.

Euphonix CO-600 Change-Over System For New Core DF66 Redundancy

Overview

The change over redundancy system allows running a backup DF-66 SuperCore in
parallel with the primary unit. The change over switch distributes all audio signals to
both the primary and backup DSP cores. If the diagnostics system detects a fault, or even
a potential primary DF-66 failure, the entire output audio path (including all I/O devices)
is switched over to the backup system. This can occur automatically or be initiated by
the console operator. Setup for this is available in the Status page of either Emix or
MaxAir Application.

Each card in the Change Over chassis can accommodate all of the I/O for one SP662

card in the primary and backup DF66 SuperCores. You don’t require a Change Over

card for each Core card just the number of I/O needed. An Ethernet connection to the S5/

MaxAir network is required. Emix/MaxAir displays the status in the system page with

full diagnostics.

The CO-600 has two primary functions: 1) a MADI splitter that provides 2 MADI
outputs for each MADI input and 2) a MADI switchover that switches each MADI
output between Primary and Backup MADI sources. Figure 1 provides a conceptual

block diagram of signal ow and behavior. External MADI inputs are distributed to both

the Primary Core and the Secondary Core so that the sources are always available to both
cores. The MADI outputs from each core are connected to the CO-600 and available for
switchover during a technical fault. The unpowered state of the system is connectivity
to the Primary Core.

A conceptual block diagram of a single CO-600 is provided in Figure 2. Features
available include redundant PSU’s with dual IEC AC inlets, GPIO, Fan Tray, CMM,
Chassis Control module, Chassis control linking, environmental sensors, Ethernet, and
up to four Change-over cards.

Chassis Management

Provision for the optional CM604/CM606 is be provided. The CM604 queries information
such as eld replaceable unit status, presence, and performs health monitoring of
system components. It also controls, when present, the power-up sequencing of each

component and the power-on/off to each slot. It is designed to work in conjunction with
GrassValley’s NetCentral™ remote facility monitoring SNMP software.

Front and Rear PanelsFigure 3

Front Panel

The front of the unit consists of eight card slots in a 2U chassis. The four full-length slots

on the left side can be lled with change over cards. The four half-length slots on the

right side are used for two hot swappable power supply modules, a frame controller card
and a SNMP chassis management card.

Indicators

Each of the change over cards provides indication of the current switch state (A or B
selected for output), input MADI signal presence, card status, out of service and fault
status. Power supply modules have power on indication and the frame controller card
has a processor active indicator. The chassis management card has additional power,
temperature and cooling status indication.

Front Panel Control

There is a switch located on the front of each change over card that allows local manual
override of the output relay position in the event of a control system failure. In the Auto
(middle) position, the remote control input on the change over frame controller card
determines which output is active.

Rear Panel

The rear panel of the unit has four full-length card slots on the right side for MADI I/O
modules.

Each module supports four MADI signals (up to 256 channels) connected to and from the
I/O, primary and backup DSP cores. With four cards in the chassis, the change over unit
can support up to 1024 audio channels. The left side of the rear panel has four half-height
card slots. Dual power inlets for the two power supplies are 8HP (two slots) in height.
The two other slots are used for frame controller and chassis management connections.
