CHEETAH SERIES SWITCHERS – CHAPTER 2

Chapter 2 CHEETAH 64 SERIES INTRODUCTION

81-9059-0577-0 Rev. E

2.1 C

Cheetah 64 series switchers are full-featured video matrix switchers capable of handling Serial
Digital Interface (SDI) and High-Definition Television (HDTV), as well as other non-standard
digital signals, in the same frame. Copper and optional fiber input and output modules provide for
maximum flexibility.

2.2 C

Additionally, PESA offers analog cards for the Cheetah 64 series switchers, which will allow users
to maintain legacy equipment during the transition to digital or single-ended, general purpose
NTSC video transmission applications such as video data for telemetry, radar, surveillance, high­level TTL video switching, and 75Ω audio. The analog inputs can accept signals from DC to the –
3dB roll-off at 50 MHz with voltages up to ±2V standard and ±5V for high level.

To maximize the analog offering for the Cheetah 64 series, all frame sizes (64NE, 64XE, and
64WE) will accept analog matrix and I/O cards. Cheetah 64 series system configurations will
allow partitioning for either all analog or all digital cards to reside in the same frame in blocks of
64x64 and 64x128. The 64NE, 64XE, and 64WE frames can be configured for either all digital or
all analog.

The following types of analog I/O cards are available:

HEETAH 64 SERIES PRODUCT OVERVIEW

HEETAH 64 SERIES SWITCHERS ANALOG SUPPORT

• Basic analog input cards, output cards, and matrix cards with maximum bandwidths of 50

MHz.

• Analog input cards and an output cards for high-level signals to support telemetry or other

types of sine wave signals with voltage levels to a maximum of ±5V p-p.

Basic analog output cards and the High-Level cards will accept the optional dual-output, piggyback
cards.

The frame architecture for the analog model uses common components from sister HD/SD frames,
thus allowing for easy future migration to full digital. Power supplies and matrix control cards are
the same for Cheetah 64 series analog versions.

HEETAH 64 SERIES SWITCHERS FEATURES

2.3.1 Cheetah 64 Series Switchers Features Overview

All Cheetah 64 series (64NE, XE, and WE) video matrix switchers offer alarm support, switch
confirmation, block checking, and power-out-of-range indicators. A key feature of the 64NE and
64WE switchers is the Matrix Watchdog™ redundant crosspoint (matrix) option. For critical
routing requirements of live, on-air situations or other critical distribution facilities, a redundant
crosspoint can be added to automatically swap over in case of failure. This feature is offered as
an option in our basic configurations. The Watchdog™ option includes monitoring capabilities
to alert personnel of a crosspoint failure.

The Cheetah 64XE is an extremely flexible routing switcher that can be configured in three ways.
First, the 64XE expands outputs for a basic 64X128 configuration similar to the 64WE model.
Next, the 64XE is offered as a 64X64 that offers output option slots for in-frame format
conversion cards. In this configuration, three options are available:

• HD to SDI down-conversion,

• SDI to Composite Analog Video (DAC)

• Fiber Outputs

• Dual Outputs

The 64XE is further enhanced with an option to support either internal fiber or coax I/O. Finally,
for those applications that require only a portion of the frame to be configured for output options,
the 64XE is flexible enough to accommodate the following three additional sizes:

• 64x80: Output options for 17-64 (first option slot used for 65-80)

• 64x96: Output Options for 33-64 (first two option slots used for 65-96)

• 64x112: Output Options for 49-64 (first three options slots used for 65-112)

The 64WE includes non-expandable outputs (similar to the 64NE) with output options (similar to
the 64XE) and has redundant crosspoints.

2.3.2 Cheetah 64 Series Switchers Standard Features

The Cheetah 64 series features include:

• Compact 4RU for the 64NE configuration; 6RU for the 64WE and 64XE configurations

• Full feature control system using either standard PESA PRC Control or PESA Network

Control (PERC2000, 3500Pro or 3500Pro-LE)

• Video and data signals from 3Mb/s to 1.48Gb/s

• Optional Fiber Input and Output cards for the 64XE and 64WE frames

Chapter 3 CHEETAH 64 SERIES CONFIGURATION MATRIX

3.1 C

This section includes a list of all of the major components for the Cheetah 64NE, 64XE, and 64WE
Video Matrix Switchers chassis/frames (models).

When discussing output options and expandable outputs, the meanings are as follows:

Table 3-1 includes only the active cards that are required for the individual Cheetah 64 series
chassis configurations. The blank covers (if necessary) are required for the card locations that are
not used (to satisfy chassis component cooling requirements).

Table 3-2 includes PESA part numbers for the corresponding Cheetah 64 Series cards, power
modules, and other components

HEETAH 64 SERIES CONFIGURATION MATRIX OVERVIEW

• Output Options pertains to which cards can go into a particular output slot in the frame for a

specific configuration(s). This includes cards that offer signal expansion or conversion such
as dual outputs, HD to SDI down-conversion, Digital to Analog conversion, and electrical
(copper) to fiber conversion. Option cards are offered as “piggy-back” modules that plug
onto the base output combiner card.

• Expandable Outputs pertains to the number of outputs that a particular frame can be

expanded beyond the basic configuration (e.g., 80, 96, 112, or 128 outputs).

Chapter 5 CHEETAH 64 SERIES INITIAL SETUP

This section will describe the initial unpacking, site-selection procedures/sequences, and settings
for the Cheetah 64 Series switchers.

5.1 U

NPACKING AND INSPECTION

This equipment contains electrostatic sensitive devices (ESD). Use a grounded
wrist strap, grounding mat, and/or comply with local established ESD
procedures when handling the internal circuit cards to prevent destruction
from electrostatic discharge.

Immediately upon receipt, inspect all shipping containers. Carefully unpack the equipment and
compare the parts received against the packing list. If any parts appear to be missing or damaged,
please contact PESA immediately.

CHEETAH 64 SERIES – CHAPTER 5

81-9059-0577-0 Rev. E

5.2 G

The physical size of each Cheetah Series Switcher chassis is determined by the chassis input/output
capabilities (i.e., the 64NE chassis is the smallest while the 64XE and 64WE chassis are the
largest). If specified when ordered, each Cheetah Switcher will be configured for the intended
system at the factory. Before attempting to install any frame, matrix card, controller card, or power
supply, carefully read and understand this section.

5.3 C

This equipment is designed for installation in a standard 19" equipment rack located in an
environment conforming to the specifications for each chassis. Locate each unit as closely as
possible to its associated equipment to minimize cable runs.

Consider the connection from this equipment to the supply circuit, and the effect that possible
overloading can have on overcurrent protection circuits and supply wiring. Refer to nameplate
ratings when addressing this concern.

ENERAL CHASSIS INSTALLATION OVERVIEW

All Cheetah Switchers contain electrostatic sensitive devices (ESD). Care
should be used when it is necessary to handle the internal circuit cards. It is
recommended that a grounded wrist strap and grounding mat be used before
attempting any equipment installations.

HOOSING A LOCATION

For local electrical compliance, this equipment shou
socket-outlet, power strip (if plugs are used), or the supply
disconnect/breaker so that the AC line cord plugs or the supply disconnect
are easily accessible.

Installation or removal of this equipment requires at least two persons in

order to avoid possible personal injury or equipment damage. Install this
equipment in such a manner as to avoid any tipping hazard from uneven
loading of the rack.

Make sure that all power is disconnected (Lockout/Tagout) before installing
the specific frame into the rack.

Fans that are mounted on this equipment provide forced-air cooling. Do not
block airflow around these fans. Replace all service panels and blank filler
plates. Keep the chassis door closed during normal operation.

This equipment is designed for installation in a standard 19" equipment rack. Provide sufficient
space behind the equipment racks to allow for control, signal, power cables, and free airflow after
all cables are installed. Use all chassis mounting holes and tighten mounting hardware securely
by using the rack equipment manufacturer’s suggested torque settings.

Install the equipment into the rack as follows:

1. Carefully, remove the equipment from the packing container and place the unit near the

rack where it will be installed.

2. Insert the chassis into the equipment rack and support the bottom of the chassis while the

mounting hardware is being installed.

3. Install the bottom two chassis mounting screws.

4. Install the top two chassis mounting screws.

5. Install any remaining chassis mounting screws.

6. Tighten all of the chassis mounting screws until they are secure. Release/remove the

support from the bottom of the chassis.

HASSIS LEVEL CODES (STROBES

)

This subsection will be divided into the following two subtopics:

• Cheetah 64NE Chassis Strobe Switch Locations and Settings

• Cheetah 64XE and 64WE Chassis Strobe Switch Locations and Settings

Set the level codes (strobes) BEFORE installing the matrix frame controller
card.

To set the level codes for all Cheetah Series chassis, use the rotary switches to define a
hexadecimal number. Use the settings in the LSB row (lower row) first. For example, to set the
Level Strobe to 12, set the LSB Level Strobe switch to C. Switch functions are described in the

CONNECTIONS

6.1 C

Use the following guidelines when connecting equipment cables:

ONNECTING EQUIPMENT CABLES

1. Install the equipment in the rack before connecting cables.

2. Relieve strain on all cables to prevent connector separation.

3. To the extent possible, separate control, signal, and power cables to minimize crosstalk and

interference.

4. Use as many cable ties as necessary to secure cables to the rack (see Figure 6-1). This will

minimize the amount of force transmitted to the equipment and help route cables away from
hazardous areas.

5. Route cables away from physical traffic areas to avoid creating a safety hazard (trip or

shock).

6. Bundle together any cables connected to a single input/output card and separate them from

the other bundles with enough slack to create a service loop. This will permit individual card
replacement without disruption to the other input/output cards.

Chapter 7 FRAME AND CONTROL VERIFICATION

This section addresses the system components, frame, and control verification sequences that should be
performed prior to energizing the system and placing the system in service. Attention to this section
will minimize system startup and in-service malfunctions.

7.1 S

7.2 S

YSTEM PRE-START VERIFICATION CHECKLIST

A system pre-start verification checklist includes a visual inspection to account for basic setup
functions that, if incorrect, could result in immediate system startup malfunctions. The following
basic checks should be performed prior to energizing any Cheetah chassis:

1. Verify the main power source is OFF (de-energized).

2. Verify all cards/modules are latched and secure.

3. Verify all blank covers are in place and secure (no open slots in the frame).

4. Verify the line cord(s) are connected to the chassis and are properly terminated to the source
power distribution system (i.e., connectors plugged in or pigtails terminated).

5. Inspect for unusual items such as loose wiring, frayed cabling, loose connections or
components, and missing cards/modules (basically, check for anything that seems out of
place or could present a problem).

6. Proceed to System Startup.

YSTEM STARTUP

Perform the Cheetah system startup sequence as follows:

1. Energize the main power source to the chassis.

Result: The system has a 30 to 45 second delay prior to energizing the components. When

the delay has expired, the system will energize and the cards will perform initial
self-diagnostics.

Verify the blank-cover panels are securely in place. These panels are an
integral part of the chassis cooling system. A loose, broken, and/or missing
blank-cover panel could result in destructive overheating of equipment
components.

Proprietary Information of PESA Switching Systems 7-1

CHEETAH 64 SERIES – CHAPTER 7

81-9059-0577-0 Rev. E

2. Verify the following LED conditions:

If any of following LED conditions are different than specified, perform
troubleshooting sequences to correct the problem(s) prior to placing the
system in service.

a. On the Power Supply module, the Power OK LED is illuminated (green)
b. On the 64x64 Matrix module, the following LEDs are illuminated:

• +28 (green)

• +3.3 (green)

• +2.5 (green)

c. On the Matrix Frame Controller (MFC), the following LEDs and LED display are

illuminated (single or dual modules):

• Single module: the Control Status display indicates - ØSNGL OK (red)

• Dual modules: the Control Status display of the active module indicates –

Active OK while the other module indicates Standby

• Active (green – illuminated on single and Active modules only)

• +28 (green)

• +5 (green)

• +3 (green)

d. On each of the Input and Output modules, the Power LED is illuminated (green).
e. PERC2000 Series System Controller module(s) only. If one or two PERC2000 cards

are installed in the Cheetah chassis, verify on each system controller card that the
following conditions exist:

1) Both the PWR IN and REGS OK LEDs are lit.

2) Verify the ACTIVE LED is illuminated. With a dual PERC2000 System

Controller configuration, verify that the ACTIVE LED is illuminated on only
one of the controller cards.

f. 3500 Series System Controller module(s) only. If one or two 3500 Series cards are

installed in the Cheetah chassis, verify on each system controller card that the
following conditions exist:

3) Dual 3500 Series System Controller module configurations:

• If both 3500 Series System Controller modules’ active/standby switches

are in the Standby or Active position, then Frame Slot A determines the
active module. Otherwise, the active module is selected by the individual
module’s switch settings.

4) Any 3500 Series System Controller configuration, the Active (amber – on the
active module) and Run (green) LEDs are illuminated.

Proprietary Information of PESA Switching Systems 7-2

5)

At the end of this sequence, there should be no LED indicators that are
blinking or any red LEDs illuminated on any of the I/O and Matrix
modules/cards. If so, perform troubleshooting to correct the status before
proceeding to the next step or section.

3. Startup Sequence complete. Proceed to Frame Control Verification, Section 7.3.

RAME CONTROL VERIFICATION

7.3.1 Frame Control Verification Overview

Frame control verification is required to verify Cheetah chassis component operations and isolate
abnormalities prior to connecting peripheral equipment to the system. To assist the user, this
verification sequence uses a graphic user interface (GUI) that is communicating directly with the
chassis Matrix Frame Controller (MFC) for the diagnostic portion of the sequence. The
following equipment/documentation is required:

• PC with preloaded PESA ViewPort software.

CHEETAH 64 SERIES – CHAPTER 7

81-9059-0577-0 Rev. E

• Null-modem serial cable (length determined by distance the PC will be from the chassis)

• ViewPort Manual (P/N 81-9059-0558-0)

• Customer’s Cheetah chassis packing list or specification sheet.

7.3.2 Frame Strobe Setting Verification

While referring to the appropriate Chapter for the frame that is being verified, document and
archive the frame’s present strobe settings as follows:

1. Access the MFC compartment. If necessary, remove the top-most MFC module and blank

cover to expose the strobe switches for viewing.

2. Document each strobe switch setting and archive. (Archiving should include an electronic

file and hard-copy for ease of future retrieval. This information is invaluable when
communicating with the PESA Customer Service group.)

3. Re-install the components that were removed in Step 1.

7.3.3 Frame Control Verification Procedure

Perform the following sequence:

1. Perform the chassis pre-start verification checks and startup sequences as outlined in

Sections 7.1 and 7.2 in this Chapter.

2. With the chassis energized (ON) and while referring to the ViewPort manual, carefully

connect the null-modem serial cable to the MFC, DB-9 serial connection port and the PC’s
serial port.

INSTALLATIONS

This section documents the operational descriptions of the various components of the Cheetah
Series Switchers. Typically, this section is accessed for more concise component information and
how each component is used in the Cheetah Series systems.

Additionally, this section will describe the installation of the various components of the Cheetah
Series Switchers. Even though the unit is shipped with all of the components preinstalled, this
section is typically accessed for basic component information and for their replacement (removal
and installation) sequences.

8.1.1 Cheetah Series Power Supply Information

HEETAH SERIES POWER SUPPLIES

Cheetah Series Power Supplies contain electrical shock hazards and should
only be serviced by qualified service personnel with experience in servicing
off-line switching regulators.

There are no user serviceable parts contained in the Cheetah Series Power
Supplies. All service performed on the Power Supplies should be performed
by the PESA Service Department.

High Leakage Current at 240VAC. The Cheetah Series Power Supply
leakage current exceeds 7.0mA when used at 240 VAC because of leakage
through emission filter capacitors.

The Cheetah Power Supply is responsible for providing a regulated ±28VDC @22A to the
switching frame. The Cheetah Power Supply is designed to operate automatically with input AC
line voltage ranges from 95-240 VAC and with AC line frequencies of 50/60 Hz. All Cheetah
power supplies have built-in, over-current protection circuitry. When two supplies are used, each
supply is electrically connected to a common/dedicated buss within the chassis and from there, to
the fuse block for overcurrent protection and distribution.

Additionally, each power supply contains dual internal fan controller systems that are isolated
from the main DC power output buss connections. Depending on the chassis, there are
dependent power supply installation configurations to satisfy the fan operations. In a two-supply
system, one supply module becomes the master and the other becomes the slave.

In the event of a Cheetah Power Supply failure, return the malfunctioning unit to the PESA
Service Department for replacement. The power supplies contain lethal voltages when operating
and should be serviced only by the PESA Service Department. Please call PESA’s Service
Department for a RMA number before returning any units for replacement. The Service
Department’s phone number is listed on the front page of this manual.

8.1.5 Installing the Power Supplies

Install each power supply as follows:

1. Align the metallic support plate of the first power supply vertically with the card guides in
the chassis.

2. Press upward on the power supply latch located on the front bottom of the assembly and
carefully insert the power supply into the chassis until the connectors on the power supply
make contact with the backplane connectors.

3. Firmly, push the power supply unit into the chassis until the power supply latch engages
the corresponding slot in the chassis.

The latch on the power supply acts as a retainer latch and a power ON/OFF
switch for the unit.

4. Make sure the latch is fully engaged (down and secured/mated into the corresponding slot
in the chassis) to enable (energize) the power supply.

Refer to the appropriate chassis location and allocation descriptions for the

CHEETAH 64 SERIES – CHAPTER 8

81-9059-0577-0 Rev. E

Each slot must have either a power supply or a blank installed. Refer to the
specific section in the manual for the correct slots for your configuration.

If applicable, repeat the above Steps for the remaining power supplies.

8.1.6 Removing the Power Supplies

To remove a power supply, follow these steps (you may remove power supplies while the
Cheetah system is operational [energized], which is called hot-swapping):

Make sure you will still have the minimum number of power supplies
installed before removing power supplies. The minimum number depends
on your configuration, which is either one or two power supplies. If you
only have one supply installed and you must remove it, de-energize the unit
first.

1. Open the Cheetah front cover.

When the latch on the power supply is moved to the full-upward position,
the power supply is switched off and is freed from the retaining slot in the
chassis.

2. Push and hold the latch on the lower front of the power supply in the full-upward position.

3. Once the latch is pushed upward and held, use the unit handle and carefully pull the power
supply out of the equipment chassis (the unit is held in place by connector plugs and
requires a slight forceful-pulling motion to separate it from the connectors). Repeat for
each power supply that you need to remove.

8.5 3500 S

The Cheetah may contain up to two 3500 Series System Controllers (see Figure 8-4). If the
primary controller fails, the secondary controller automatically resumes all of the primary
controller functions. The System Controller, working in conjunction with the 3500 Series Control
System software, enables users to configure and operate a switcher system from a standard IBM
compatible PC. The System Controller interfaces between the routing switcher and all user­controlled elements, including RCPs, PCs, etc. Based upon configuration data input during setup
and installation, the System Controller sends appropriate I/O control signals to the Cheetah 64x64
Video Matrix Card.

8.5.4 Battery ON/OFF Select Switch

This SPDT toggle switch is used to enable and disable the backup memory power source. Early
designs of PESA system controllers used a battery for backup power. This switch was used to
prevent the battery from discharging during prolonged storage.

The 3500 Series System Controller uses a capacitor as a backup power source, which does not
need to be isolated during storage. This switch should be in the ON position at all times.

8.5.5 Reset

This SPDT momentary pushbutton switch is used to manually reset the 3500 Series System
Controller in the event of system failure or lockup (similar to a warm boot on a PC). To reset the
controller, press and hold this switch for about three seconds.

8.5.6 Mode

This SPDT toggle switch is used in a dual-controller system to designate the primary controller
and the backup controller. Set the Mode switch to ACTIVE on the primary controller, and to
STANDBY on the backup controller. In a single controller system, this switch has no effect.

The matrix frame controller, located on the right front of the unit, is illustrated in Figure 8-7. For
every frame type, at least one Matrix Frame Controller (MFC) is required. The function of the
frame controller is to determine frame size, level, input offsets, output offsets, plus other physical
characteristics of the frame hardware. Both PESA’s PRC protocol and NET PRC protocol are
available to the MFC. With the NET-PRC protocol, the MFC has the ability to communicate to a
system controller via Ethernet connection. More features include SNMP support and redundant
MFC cards with auto changeover. On the front panel of each matrix frame controller is a

CHEETAH 64 SERIES – CHAPTER 8

81-9059-0577-0 Rev. E

The 3500 Series controller initiates a system alarm. An alarm condition is declared when the
controller is in reset and when the standby controller is gathering configuration information from
the primary controller. During an alarm condition, an optically isolated, electronically closed
circuit (see Figure 8-13 on next page) exists between contacts 3 and 1 for Controller A (top) and
contacts 2 and 1 for Controller B (bottom). This circuit acts as a switch to trigger an optional
external alarm in the event of a controller fault or failure. The controller alarm circuit supplies an
electronic contact closure, but does not provide a voltage to the external alarm.

The Customer-supplied alarm circuit voltage to this connector must not
exceed 12VDC and the associated amperage must not exceed 10mA.

The alarm is activated if any of the following 3500 Series software conditions exist:

• Encounters an interrupt that it does not expect or can not process

• Is unable to synchronize with the other 3500 Series controller (dual controllers)

• Does not get the configuration from the other 3500 Series controller (dual controllers)

8.8.8 House Synchronization Input Connectors

These BNC coaxial connectors, illustrated in Figure 8-23, provide the interface for two, house
(analog only) synchronization signals (i.e., NTSC, PAL, 1080i, 1080P, and 720P only). The
house sync inputs are individually terminated internally. The synchronization signal cannot be
daisy-chained from one routing switcher to another.

F

IGURE

8-23 House Sync Input (Reference) Connectors

Using the Cheetah GUI, the user can assign a specific reference signal for the system or
individual chassis that is used as a synchronization signal for specific output synchronized
switching. Once the output has been switched, the output signal remains synchronized to the
initial reference assignment until it is switched again with a new reference assignment. An
example of a sync assignment would be as follows:

81-9059-0577-0 Rev. E

Ref 1

Ref 2

Reference 1 is connected to an NTSC sync signal source and Reference 2 is connected to a
PAL sync signal source. Using the GUI, the user assigns Reference 1 to outputs 6 through 10
and Reference 2 to outputs 11 through 16 for a specific chassis.

Reference 1 or 2 should be connected to the house sync source or tri-level source with coaxial
cable and standard BNC connectors.

Chapter 9 MAINTENANCE AND REPAIR

This section will address the normal system maintenance sequences, basic troubleshooting
scenarios, minor system repairs, and PESA contact information.

Since it may become necessary to perform maintenance and repair on energized equipment, it is the
responsibility of all personnel involved in the maintenance and repair of the equipment to be
familiar with all of the applicable safety regulations for the areas they will be working in. Under

no circumstances should any person perform any procedure or sequence in this manual if the
procedural sequence will directly conflict with local Safe Practices. Local Safe Practices shall
remain as the sole determining factor for performing any procedure or sequence outlined in this
document.

81-9059-0577-0 Rev. E

9.1 M

AINTENANCE

9.1.1 Maintenance Overview

This equipment has been designed to give long, trouble-free service with very little maintenance.
Under normal service conditions, the only routine maintenance required is to monitor the air
filter for cleanliness.

This equipment contains static sensitive devices. A grounded wrist strap and
mat should be used when handling the internal circuit cards.

This equipment has been designed so that maintenance operations can be
performed while the equipment is operational (energized and performing
switching functions). Only the power supply assemblies and the AC supply
line circuits contain potentially lethal shock hazards.

9.1.2 Air Filter

The air filter(s) should be checked monthly to ensure that an adequate supply of clean air is
available to cool this equipment. If the air filter is dirty, either clean it with low-pressure air,
vacuuming, or a mild soap-and-water solution (then dry); or replace it with a new air filter
(PESA Part No. 81-9065-2360-0).

Proprietary Information of PESA Switching Systems 9-1

9.1.3 Fan Replacement Sequences

The fans that are used in all Cheetah chassis configurations are continuous duty, ball bearing,
24VDC brushless, circulating fans. In operation, the fans are voltage-controlled by the power
supplies, which receive feedback from the system heat sensors. That is, as the heat increases, the
fan voltage is increased thus increasing the fan circulating speed and vice-versa. All fan
assemblies in Cheetah chassis are “hot swappable”.

All fan assemblies used in the Cheetah Series switchers have a continuous­duty rating of 40,000 hours. It is recommended that predicted failure and/or
preventive maintenance schedules be implemented to replace fan assemblies
during scheduled maintenance periods for fan assemblies that have exceeded
30,000 to 35,000 hours of operation.

Since the fans are electro-mechanical devices, they will eventually fail due to wear. All fan
assemblies are monitored for proper operation and a system alarm is initiated whenever a fan is
not operating correctly or has failed.

CHEETAH 64 SERIES – CHAPTER 9

81-9059-0577-0 Rev. E

Only authorized personnel should attempt repair or replacement of fan
components. Potential injury or equipment damage exists during fan
replacements. Always disconnect power to the fan prior to any fan
replacement.

Cooling is an integral part of the Cheetah system operation. Any fan alarm
must be addressed and corrected as soon as possible. Continued operation of
the equipment during a failed fan(s) condition could result in catastrophic
equipment failure.

Replace switcher fan assemblies only with PESA-approved replacement fan
assemblies. All PESA-approved fan securing #6 hardware should be
tightened to no more (non-lubricated) than a torque values of 9.6 inch-pounds
and #8 hardware to no more than 17.8 inch-pounds.

There are two types of fan assemblies that are used for the Cheetah series, which are as follows:

•

Surface-mount fan assembly (fan is mounted externally to the surface of the chassis)

•

Flush-mount fan assembly (fan is mounted internally and is “flush” with the surface of the
chassis).

This section will address the replacement sequences for each type of assembly in the Cheetah 64
Series chassis.

Proprietary Information of PESA Switching Systems 9-2

9.1.4 Cheetah 64 Series Fan Replacements

These switchers are equipped with two, surface-mounted fan assemblies (see Figure 9-1) that are
easily removed from the rear exterior of the chassis.

2. Remove the four fan-assembly retaining screws.

3. Replace the fan and secure with the four, fan assembly with the retaining screws (torque
according to screw size).

When replacing fans during energized system conditions, be aware that the
new fan replacement will energize upon power reconnection.

4. Reconnect the fan power cord to the chassis fan power receptacle.

ROUBLE SHOOTING

9.2.1 Troubleshooting Overview

Troubleshooting techniques differ from technician to technician. However, all techniques should
include a basic troubleshooting starting sequence, which consists of, but is not limited to, the
following:

•

An Operator interview to account for system actions prior to the system problem to
establish failure possibilities

•

Verification of correct supply voltages (breaker or disconnect status, supply voltage
actually present, etc.)

•

System fuse verification (search for open/blown system fuses)

•

An initial system inspection that includes the use of personal senses (e.g., feeling for heat,
smelling for burned components, listening for unusual noises, and looking for discolored
components)

Once the basic troubleshooting starting sequence has been completed, then the actual system
troubleshooting (physical portion) can begin.

This section assumes that the basic troubleshooting starting sequence has been completed and the
actual system troubleshooting sequence has begun.

9.2.2 Subassembly LEDs

Cheetah Series equipment has been designed to provide the user with basic monitoring and
diagnostic system information. If the Cheetah equipment fails to operate correctly, check the
appropriate LEDs listed in the following Tables (Tables 9-1 through 9-4) for the system’s
individual components (cards/modules) for information concerning their (and the system’s)
operational status and suggested actions to perform accordingly.

PPENDIX A: ETHERNET CONFIGURATION

The Matrix Frame Controller supports a variety of interfaces via the Ethernet interface. These
include NET PRC, HTTP (HyperText Transfer Protocol - web), SNMP (Simple Network
Management Protocol), and Telnet. To configure this access, the following items will need to be
configured (refer to Table 10-1):

The network server automatically assigns the IP Address, Subnet Mask
specification, and Gateway specification when the Dynamic Host
Configuration Protocol (DHCP) is enabled.

10.2 A

The Cheetah Matrix Frame Controller contains an SNMP v2c agent, which is also compatible with
SNMP v1 management stations. The agent supports the following standards:

Two enterprise MIBs are used to provide full control of Cheetah Switchers. The first, PESA­TC.MIB, is a MIB, which defines some textual conventions. The second, PESA-MATRIX.MIB,
contains objects, which allow SNMP-based control and monitoring of one or more Cheetah
Switchers.

Note that the agent within the Matrix Frame Controller implements a subset of the PESA-MATRIX
MIB. The optional Group tables are reserved for implementation within the System Controller.

The agent is capable of managing multiple Cheetah Switchers. This is accomplished in two steps:

PPENDIX B:

a) Connecting the Cheetah Switchers via the RS-422 Aux Frame Port described in this manual.
b) Set the Matrix Frame Controller, which is to communicate with your SNMP management

application to NETPRC Master. Note that if you have redundant Matrix Frame Controllers
in the Switcher, BOTH must be configured as NETPRC Master. Refer to the Ethernet
section described earlier in Appendix A to accomplish this.

c) Set all other Matrix Frame Controllers, which you have connected, to the NETPRC Master

controller to NETPRC Slave.

The agent will then be able to configure and control all of the Cheetah Switchers in the connected
collection.

Once you have configured the Matrix Frame Controller's SNMP agent (as described in Appendix
A), you may issue SNMP commands. The following commands were issued on a PC running
Linux against a pair of small Cheetah Switchers.

The next set of commands creates a preset (a collection of switches that are to be taken as a
group). In this case, the preset contains two switch definitions (preset members). The first
connects source 1 to destination 1 on level 2. The second connects source 2 to destination 2, again
on level 2. Both are set to utilize the synchronization signal A (REF 1 on the Cheetah back panel).

PPENDIX C:

The PESA Matrix Frame Controller Debug Port protocol is an RS-232 connection that allows
service personnel to directly interact with the PESA Matrix frame controller in order to determine
the health of the matrix and to perform certain diagnostics. The same protocol is supported via the
Telnet connection; however, the network parameters cannot be configured through the Telnet
connection.

D2: Command Syntax

CHEETAH 64 SERIES – CHAPTER 10

81-9059-0577-0 Rev. E

ATRIX FRAME CONTROLLER DEBUG PORT PROTOCOL

Commands consist of the first two non-whitespace ASCII character sequences entered in a
command line.

Each command is followed by a series of optional data parameters. Data parameters start after the
first whitespace following the command sequence. Commas delimit the data parameters. All data
parameters have leading and trailing whitespaces trimmed.

A command is terminated by a Carriage return. A command is not acted on until the carriage
return is received.

Command sequences are case insensitive.

D3: Command Line Character Input

The following indicates how characters input into the debug port are handled.

1) Command Entry

Commands are entered character by character onto the command line. All ASCII keys are
concatenated onto a string. In addition, entry of the DELETE or BACKSPACE keys will
cause the last character that was entered to be removed from the character string.

In verbose mode, all ASCII characters entered into the serial port are echoed back. The
DELETE and BACKSPACE keys cause control characters to be echoed that cause the cursor
to move back deleting the last character input.

In terse mode, the input characters are not echoed back.
After a command has been executed, the debug port will output the appropriate response (if

any) followed by a Carriage Return/Linefeed and the ‘>’ character. The receipt of the ‘>’
character indicates that the next command is ready to be entered.

CHEETAH 64 SERIES – CHAPTER 10

81-9059-0577-0 Rev. E

2) Verbose Mode

The verbose mode responses include text information and formatting that describe the
command response in terms that can be read by a user that is using a terminal interface to the
debug port – i.e., Human-Machine Interface (HMI).

• Ctl-C – Aborts the current command and starts new command line with a new prompt.

• Ctl-V – Verbose Response Mode (default) – Causes responses to be returned in a

verbose mode fit for human consumption of data (plain language).

3) Terse mode

This mode outputs minimal information that fully describes the necessary response data. Its
intent is to be read from an automated device such as a PC – i.e., Machine-Machine Interface
(MMI).

• Ctl-C – Aborts the current command and starts new command line with a new prompt.

• Ctl-T – Terse Response Mode – Causes commands to be responded to in a terse mode

fit for machine consumption of data (programming language).

D5: Command Enumeration

Command Characters in BOLD are those characters that are required for the command. The other
characters may be entered to help describe the command to a user interface.
