Chapter 2 INTRODUCTION
2.1 P RODUCT O VERVIEW
PESA’s Cheetah 144NE Fiber Router System is a high performance, modular fiber optic switch
system for either ProAV or Broadcast HD-SDI and 3G-SDI applications, and fully supports
SMPTE 259M, 292M, 372M and 424M standards. The Cheetah 144NE Fiber is expandable in
sizes from 36X36 up to 144X144 in the same 4RU frame. It is fully compatible with the new QFX
Series of fiber media extenders for DVI, HD-SDI, and 3G-SDI. The frame supports redundant
power, control, and a hot-swappable 144X144 Crosspoint matrix. I/O cards allow easy expansion
in groups of 36 inputs or 36 outputs per card without the need to replace cards or frames.
The Cheetah 144NE Fiber is a modular design featuring four rear-panel slots for input buffer cards
and four slots for output combiner cards. Each input or output card supports up to 36 fiber optic
connections using standard LC-type fiber SFP modules. The I/O fiber cards are based on 1310nm
singlemode lasers but can be used in multimode applications with reduced performance
specifications. Singlemode fiber allows signal transports up to 10Km while multimode is limited to
approximately 400m with 50/125 cables.
With its small 4RU footprint, the Cheetah 144NE Fiber Router can be configured as a partially
loaded frame allowing for easy future field expansion. The system’s integrated Matrix Frame
Controller monitors the health of the unit and automatically recognizes any new I/O cards. Once
the cards are installed, the Cheetah 144NE Fiber Router can be easily configured with the
3500PRO or PERC 2000 System Controller software. The Cheetah 144NE Fiber Router can be
controlled from the PESA control system or by a third-party control system such as Crestron® or
AMX®.

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.
4.3 M OUNTING A C HEETAH 144NE C HASSIS IN AN E QUIPMENT R ACK
The weight of a fully loaded 144NE chassis is 60 lbs nominal. 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.

Proprietary Information of PESA 4-6
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.
4.4 S ETTING C HASSIS L EVEL C ODES (S TROBES )
Chassis Level Codes (Strobes) assign operational parameters to the switcher frame. There are eight
rotary switches, located just to the right of the power supply modules and accessible from the front
of the router, used to set the chassis level code and other frame operational characteristics. Chassis
switch settings are preset at the factory and should never need any maintenance or adjustment.
This information is provided as a reference so that in the event any switch setting should
inadvertently be changed, it can be restored to its correct setting.
Proper setting positions for these switches are shown in Figure 4-1.
Prior to adjusting any of the chassis strobe switches, it is strongly
recommended that you contact PESA’s Customer Service Department for
assistance.

5.1 C ONNECTING E QUIPMENT C ABLES
Use the following guidelines when connecting 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 5-1). This will
minimize the amount of force transmitted to the equipment and help route cables away from
hazardous areas.

IGURE 5-1 Cables Attached to Supports
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.

Once the Cheetah Video Matrix Switcher is installed in the equipment rack, the associated system
connections can be completed. Use the following guide to insure that interconnections are properly
connected and that the control, power, sync, and video cables are correctly installed (for further
detailed information, refer to the corresponding sub-section in this Chapter).
1. Connect external sync sources to reference input BNC connectors using Belden 8281 coaxial
cable or equivalent. Reference input BNC connectors are terminated into 75Ωinternal to the
switcher.
2. Connect the primary external computer to the COM 1 Connector using a 9-pin, RS-232
cable. Please note that this connection must be made to configure the internal System
Controller using the 3500 Series Control System software package. If a secondary external
computer is to be used, connect it to the COM 2 Connector.
3. If additional Cheetah Switchers are to be utilized as part of the switching matrix, connect the
PRC Loop jack on the primary Cheetah Switcher to PRC Loop jack on the other Cheetah
Switcher using 5-pin ribbon cables.
4. If an external controller (such as the 3500PRO or PERC2000 System Controller) is used to
control the Cheetah Switcher, connect the external controller to COM 3 PRC using 9-pin RS-
422 cable.
5. Connect the RCP control panels to the RCP Panel Ports (#1 and/or #2) using twisted pair
cables while observing polarity (refer to Chapter 7). Connections to control panel may be
daisy-chained.
6. If Ethernet connectivity is desired (system controller), connect a 10baseT RJ-45 LAN
connector to the System Controller Ethernet jacks.
7. Configure the Ethernet settings as described in Appendix A, paragraph 9.1 of this manual.
8. If SNMP management of additional Cheetah Switchers is to be utilized, connect the
switchers using the Frame Controller Ethernet connectors.
9. Configure the Ethernet and SNMP settings as described in the Appendices.
11. If desired, connect an external alarm to the System Control Alarm (for further connection
compliance information, refer to Chapter 7 for connector pin-outs).
12. If desired, connect an external alarm to the Frame Control Alarm (for further connection
compliance information, refer to Chapter 7 for connector pin-outs).
13. Connect video sources to video inputs using SM or MM fiber optic cable.
14. Connect video outputs to video destinations using SM or MM fiber optic cable.
