Prisma II Chassis The Prisma II Chassis accommodates up to 13 single-slot modules. This is in addition to the primary power supply. When an ICIM is installed (using two slots), the number of available slots drops to 11. When both an ICIM and a redundant (second) power supply (using two slots) are installed, the chassis accommodates 10 single-slot modules.
Chassis Front Panel Depending on your system requirements, the chassis is factory configured as either: Front access, with port and power connectors on the lower part of the front panel. Rear access, with port and power connectors on the back of the unit. 736762 736766 Presentation_ID Kirkpatrick 092509 144869 144870 (P2-CH-R-F-56-R-AAS)Chassis,Rear Acc,56F,2/AC Pwr (P2-CH-R-F-56-R-DDS)Chassis,Rear Acc,56F,2/-48VDC Pwr Part Description Power ON LED Illuminates when power is applied to the chassis.
Chassis Connections Connector Interface Panel The connector interface panel houses the electrical, signal, and alarm connectors, as well as the power inlets required for chassis operation. Chassis Inputs and Outputs Chassis inputs and outputs consist of cable assemblies that connect the backplane to ALARMS IN, ALARMS OUT, EM IN, EM OUT, ICIM IN, ICIM OUT, CLOCK INPUT, RF IN, RF OUT and the Ground Stud. Presentation_ID Kirkpatrick 092509 © 2006 Cisco Systems, Inc. All rights reserved.
Chassis Inputs & Outputs Alarms In/Out EM IN/EM OUT EM In/Out ICIM In/Out The EM IN and EM OUT connectors on the connector interface panel are used to allow TNCS element management software to control and monitor more than one chassis. ALARMS IN/ALARMS OUT These connectors allow for an ALARM OUT ALARM IN for each module slot in the chassis. ICIM IN/ICIM OUT These connectors allow one ICIM to control and monitor modules in more than one chassis.
Chassis Backplane The chassis backplane consists of the inside and the outside rear panel of the chassis through which the electrical and communication signals are connected and distributed. In addition to distributing electrical power and providing a common serial bus, the backplane also connects 4 RF ports (2 connectors are standard, 2 others are optional) to each of the 14 module connectors. Module connectors inside the chassis accommodate electrical power, digital signals, and analog signals.
Connecting the ICIM to Additional Chassis Chassis-to-Chassis ICIM Connections The Prisma II platform allows the ICIM to be located in one chassis and control modules located in several other chassis. This communication “daisy-chain” can be enabled by connecting cables to the ICIM IN and ICIM OUT. This connection is required if an ICIM in one chassis is to communicate with or control any module located in a separate chassis.
Connecting the ICIM to Additional Chassis ICIM IN and ICIM OUT Connectors Every chassis has a DB9 ICIM IN and a DB9 ICIM OUT connector for the purpose of chassis-to-chassis ICIM2 connections. ICIM IN is a female connector and ICIM OUT is a male connector. The cable required for both ICIM IN and ICIM OUT connections is a shielded 9-wire serial extension cable, DB9 Female to DB9 Male. Cisco # 180143 CIFA# 144856 All chassis connected in this daisy-chain must have a unique chassis ID number.
External Alarms Connections Master/Slave Operation All Prisma II modules ship from the factory configured as a master. The LCI, TNCS software, or the ICIM can be used to reconfigure a module as a slave or as redundant (slave). The Chassis allows for local hard-wired redundancy by using the ALARM IN and ALARM OUT connectors.
Power Supply There are two versions of the Prisma II Power Supply, AC or DC. The type that you use depends on the input voltage to your system. The two versions are functionally identical, and differ only in cable connections to chassis and input voltages. • AC Supply Cisco 4012765 CIFA 16365 • Voltage requirements 90 to 265 VAC • DC Supply Cisco 716312.001.000.
Fan Tray The Prisma II Fan Tray provides cooling to the Prisma II Chassis and monitors the Prisma II Power Supplies. The fan tray is installed in the top of the Prisma II Chassis at the factory. It can be removed for maintenance or inspection by loosening the two screws located on either side of the front panel. Important: Do not operate Chassis without a fan tray installed.

Prisma XD Chassis David Kirkpatrick © 2010 Cisco and/or its affiliates. All rights reserved.
Prisma II XD Platform The Prisma II XD Platform is a configurable and expandable system for providing transmit and receive functions to fiber-optic communications networks. The Prisma II XD Platform consists of the following products.
XD Fan Assembly The chassis uses a negative pressure fan system to pull cooling air from the ambient environment. Three fans are housed in a field-replaceable assembly attached at the back of the chassis. The fan assembly can be removed for inspection and maintenance, to provide access to the DC-to-DC converters inside the chassis, or to remove either of the AC-to-DC bulk power supply modules. Presentation_ID Kirkpatrick 092509 © 2006 Cisco Systems, Inc. All rights reserved.
Chassis Power Supply Architecture The chassis can operate from utility AC power or from external -48 VDC power. For AC operation, one or two AC-to-DC bulk power supply modules are installed in the chassis. Each of these modules supplies -48 VDC power to one of two DC-to-DC converter assemblies inside the chassis For DC operation, one or both AC-to-DC bulk power supply modules are removed, and power for one or both internal DC-to-DC converter assemblies is supplied from external -48 VDC power source.
Chassis Power Supply Architecture The following diagram shows the general power supply architecture for a single Prisma II XD Platform chassis. +24 VDC +5 VDC -5 VDC 0 VDC Application Module Power Bus DC-to-DC Converter Module A AC-to-DC Bulk Supply Module A AC IN A DC-to-DC Converter Module B RETURN RETURN -48 VDC -48 VDC DC IN/OUT A DC IN/OUT B AC-to-DC Bulk Supply Module B AC IN B Each AC-to-DC bulk power supply module feeds a separate, dedicated DC-to-DC converter assembly.
ICIM2-XD The ICIM2-XD provides users with access to application module configuration settings, status monitoring, and alarm monitoring. The ICIM2-XD is logically identical to the ICIM2 module used in Prisma II chassis. However, the ICIM2-XD is physically smaller than the ICIM2 and lacks a front-panel keypad or liquid-crystal display. Part Ethernet connector RS232 connector Function Directly connects the ICIM2-XD to an IP network.
Step 1: Install Chassis in a Rack (Just in case you have never installed a piece of equipment in a rack) 1. Use a torque wrench to tighten the bracket mounting screws to 12 to 14 in-lbs 2. Position the chassis in the rack with the fan assembly installed, but otherwise empty. 3. Insert a mounting screw through each of the four mounting holes on chassis front panel, and then into the rack. 4. Use a medium-sized Phillips-head screwdriver to tighten each mounting screw until it is tight. 5.
Step 2: ICIM In ICIM Out Cable Connections Chassis-to-Chassis ICIM Connections The Prisma II XD platform allows the ICIM2-XD to be located in one chassis and monitor application modules in other chassis. This communication “daisy-chain” can be enabled by connecting cables to the ICIM IN and ICIM OUT connectors on the chassis interface panel. Presentation_ID Kirkpatrick 092509 © 2006 Cisco Systems, Inc. All rights reserved.
Step 2: ICIM In ICIM Out Cable Connections 1. Connect the serial extension cable (CIFA 144856) from the ICIM OUT of the chassis containing the ICIM2-XD to the ICIM IN connector of the second chassis. 2. Connect a serial extension cable from the ICIM OUT of the second chassis to the ICIM IN of the third chassis, if installed, third chassis to fourth etc. 3. Change the chassis ID numbers as needed to give each chassis an appropriate unique ID number.
Step 2: Change Chassis ID Number 1. Locate the chassis ID switch at upper right on the front panel of each chassis. The switch can be set to any two-digit value from 00 to 99 (but avoid setting the value to 00, as explained below). 2. Use the chassis ID switch to set each chassis ID number to a unique value. Note: The chassis ID number can be changed while the chassis is under power. However, the new ID number will not become effective until chassis power is cycled or the ICIM2-XD is rebooted.
Step 3: Make Electrical Connections The chassis back panel has an IEC standard AC power inlet and a threeconductor DC power connector for each bulk DC power supply module slot. The AC power inlet accepts line voltage at 100 to 240 VAC, 50 or 60 Hz. The DC power connector accepts DC input voltage at -40 to -72 VDC (-48 VDC nominal). The power connectors on the left side of the chassis supply power to the left power supply slot, while those on the right supply power to the right power supply slot.
Step 3: Make Electrical Connections ~ DC Power Systems External -48 VDC operating power for each DC-to-DC converter (mounted in the chassis just behind the fan assembly) enters the chassis via a dedicated DC power inlet mounted on the chassis back panel. The voltage input range for DC power systems is -40 VDC to -72 VDC. Use cable 4011730 for DC wiring. The #16 AWG wiring from the external 48 VDC supply is attached to a 3-pin nylon connector which, in turn, plugs into the DC power inlet.
Step 4: Install the ICIM2 Note: Chassis can be ordered with or without ICIM ~ follow steps if adding ICIM to non ICIM chassis 1. Remove the blanking panel covering the ICIM slot in the lower right corner of the chassis back panel. 2. Hold the ICIM2-XD so that the front panel silkscreen is in correct reading position. 3. Align the two ridges on the bottom of the ICIM2-XD with the module guide slots located in the chassis. 4.
Connecting RF Cables The chassis back panel has two RF connectors, A and B, for each application module slot. Each pair of RF connectors is numbered (1-16) to show its corresponding slot number. RF port A, leftmost in each pair, is marked by a black semicircle or nut at the base of the connector. RF port A provides connection to the upper of two independent RF channels on the chassis midplane, while RF port B provides connection to the lower RF channel.

“LASER” Prisma 1550 High Density S-QAM Full Spectrum Transmitter David Kirkpatrick © 2010 Cisco and/or its affiliates. All rights reserved.
Prisma S-QAM Full Spectrum Tx Overview The SQAM-FS is a series of full spectrum (low analog high QAM) transmitters designed for medium reach (40km) DWDM point to multipoint applications feeding multiple nodes with a single fiber Features SQAM-FS The new SQ-FS TX is a low chirp laser built and tuned for 30 analog + QAMs.
SQAM-FS Example Architecture GS7000 Node Fiber Enclosure Headend or Hub Prisma SQ-FS Optics LGX MX/DMX Field MX/DMX x8 Single Fiber GS7000 Node New SG-FS is supported in both Prisma II (shown) and XD platforms Hub/Cabinet LGX MX/DMX LGX MX/DMX x8 Single Fiber 40km 8 FWD Wavelengths Single Fiber Passives in both standard LGX packaging and cassette style for field deployment Presentation_ID Kirkpatrick 092509 © 2006 Cisco Systems, Inc. All rights reserved.
S-QAM FS TX Operation The RF input signal is amplified before being converted to an optical signal using a high-performance, isolated distributed feedback (DFB) laser. The incoming RF signal is also routed through a coupler to an RF detector circuit. The RF detector produces a DC voltage proportional to incident RF power that is used to monitor the input power level.
S-QAM FS TX Operation Transmitter gain is controlled through the selection of Manual or Automatic Gain Control (AGC) mode operation. In Manual mode, an attenuator can be used to reduce RF power. It may be desirable to make such adjustments to compensate for power differences if the channel load differs from the specified value. In AGC mode, the microprocessor monitors the actual input composite power and adjusts the attenuator to maintain constant RF drive level into the laser diode.
SQAM-FS TX Front Panel Part Function Alarm Indicator Illuminates or blinks when an alarm condition occurs. Laser Indicator Illuminates when laser is active. Optical Output Connects the output signal to the optical cable. -20 dB Test Point Provides a -20 dB sample of the RF input signal. Presentation_ID Kirkpatrick 092509 © 2006 Cisco Systems, Inc.

Host Module Empty Presentation_ID Kirkpatrick 092509 © 2006 Cisco Systems, Inc. All rights reserved.
Prisma II Chassis Installation When installed in a Prisma II standard chassis, the module is placed in a host module and then inserted into the chassis in slots 5 through 16. If the module occupies the upper host module position, its slot number is the same (5 through 16) as that of the host module. Prisma HD TX RF Flow TX 1 PII Backplane D NC C NC TX 2 B BC A BC If the module occupies the lower host module position, its slot number is 16 plus the host module slot number, or 21 through 32.
Install the Module in a XD Chassis 1. Locate the fiber tray at the bottom of the chassis and the application module slots inside the chassis as shown in the following illustration 2. Align the ridges on the top and bottom of the module with the module guide slots located on the chassis. 3. Gently slide the module into the chassis until its power and communications connections join connectors on the midplane bus. Do not force the module into the chassis.
Install the Module in a XD Chassis 4. Tighten the screw at the top of the module to secure it in the chassis. Use a 3/8-in. flat-blade screwdriver to secure. Do not over-tighten. 5. Fill any unused chassis slots with module blanks to help ensure proper cooling air flow. Presentation_ID Kirkpatrick 092509 © 2006 Cisco Systems, Inc. All rights reserved.

Prisma II EDFAs Prisma II Optical Amplifiers offer a wide range of configurations and output powers for architectural flexibility. Erbium-doped fiber amplifier modules are available in two categories: Broadcast and Narrowcast Gain-Flattened. Broadcast EDFAs are typically used for the amplification of broadcast signals which are carried by a single optical channel anywhere between 1530 nm and 1565 nm Narrowcast Gain Flattened EDFAs are designed for use in multiple wavelength systems.
Prisma II Broadcast EDFAs Broadcast EDFAs are typically used for the amplification of broadcast signals which are carried by a single optical channel anywhere between 1530 nm and 1565 nm The Prisma II Optical Amplifiers are available as Pre-Amplifier, PostAmplifier, Hybrid Amplifier, and Gain-Flattened Amplifier (EDFA) modules.
Erbium-Doped Fiber Amplifier Narrowcast Gain Flattened EDFAs are designed for use in multiple wavelength systems. This highly versatile EDFA maximizes system performance and flexibility by providing constant gain control while maintaining gain flatness for up to 40 wavelengths. The Prisma II (Full Height) gain-flattened amplifier is available at 17 & 20dBm max composite output power levels.
EDFA Operation Operating over a wide range of input powers from a TX or another EDFA, the amplifier modules provide high performance transmission of voice, video data signals for optical networking Depending on the system you ordered, the system may consist of a single amplifier module with 1 to 8 outputs or pre/post amp configuration with 10 to 24 outputs. Presentation_ID Kirkpatrick 092509 © 2006 Cisco Systems, Inc. All rights reserved.
PII EDFA Front Panel The Prisma II Optical Amplifier front panel is designed with one input connector and one or more output connectors. ALARM and LASER indicators on the front panel allow you to monitor laser and alarm status at a glance. Part Function Alarm Indicator Illuminates or blinks when an alarm condition occurs. Laser On Indicator Illuminates when there is optical power present. Optical Output Connects the output signal to the optical cable.
