Mux/Demux Motherboards and Mux/Demux Modules
Product Overview
The Cisco ONS 15540 ESPx is an optical transport platform that employs DWDM (dense wavelength division multiplexing) technology. With the Cisco ONS 15540 ESPx, users can take advantage of the availability of dark fiber to build a common infrastructure that supports data, SAN (storage area network), and TDM (time-division multiplexing) traffic. The system uses an enhanced chassis with front fiber-optic cable access for optical interconnections between transponders and optical mux/demux modules.
This chapter describes the Cisco ONS 15540 ESPx and includes the following sections:
•

Note
Cisco ONS 15540 ESPx Chassis
The Cisco ONS 15540 ESPx is a 12-slot modular vertical chassis. The system uses redundant -48 VDC inputs. A redundant external AC-input power supply is available or DC-input power can be provided directly. Slots 0 and 1 hold the optical mux/demux motherboards, which are populated with optical mux/demux modules. Slots 2 to 5 and 8 to 11 hold the 2.5-Gbps line card motherboards, which are populated with 2.5-Gbps transponder modules, and 10-Gbps line card motherboards, which are populated with 10-GE transponder modules. Slots 6 to 7 hold the processor cards. (See Figure 1-1.)
The air intake, fan assembly, cable management tray, cross connect drawers, and cable storage drawers are located beneath the modular slots. The system has an electrical backplane for system control.
Figure 1-1 shows a populated Cisco ONS 15540 ESPx shelf with a cable storage drawer and two cross connect drawers.
Figure 1-1 Cisco ONS 15540 ESPx Populated Shelf
Fan Assembly
The fan assembly is located at the bottom of the chassis and contains eight individual fans and a fan controller board. (See Figure 1-2.) The controller board monitors the status of each fan and reports the status to the processor cards. If a single fan fails, a minor alarm is reported to the processor card. If two or more fans fail, a major alarm is reported to the processor card. To prevent damage to the cards and modules in the shelf when two or more fans fail, you can configure the system to automatically reset or power off the transponder modules. The transponder modules power off if the hardware version of the line card motherboard is 5.1 or later, otherwise the transponder modules reset. Use the show hardware command to determine the hardware version of the 2.5-Gbps line card motherboards.
Figure 1-2 Fan Assembly
To recover from fan failure shutdown, you must power-cycle the shelf.
Note
Caution
Power Supplies
The optional external power supply is a single-phase, AC-DC, 1050W, -48VDC output power supply that connects to the chassis through terminal blocks. The external power supply is installed in an external power shelf that fits into a standard equipment rack. Up to three external power supplies can be installed in the external power shelf.
See the "Powering Up the Shelf" section on page 2-39 for more information about the power supplies.
Backplane
The Cisco ONS 15540 ESPx uses an electrical backplane. The power connectors on the modules connect to the electrical backplane allowing line card motherboards to draw up to 100W of power. Optical connections between transponder modules on the client side and the mux/demux modules on the trunk side are made in the front.
The alarm signals from the processor card are sent to the alarm card attached to the bottom of the backplane. They connect to the central office alarm through connectors on the backplane.
Alarm Cards
The alarm card has relays and terminal blocks to interface the chassis to the Telco Central Office alarm equipment. It is a separate card that mounts to the back of the chassis and connects to the backplane.
There are six relays on the alarm card. They are audible and visible with three levels for each type:
•
•
•
Each relay has two form C contacts. One is used to connect to the terminal block and the outside. The other is used to provide feedback on the state of the relay.
A processor card energizes the relays by driving 3.3 volts to them. Only the primary processor card drives the relays, however, each processor card can tell if the relay is energized by sensing that the feedback line is grounded through the second contact.
Table 1-1 lists the specifications for the alarm cards on the
Cisco ONS 15540 ESPx.

Note
Processor Cards
Slots 6 and 7 of the Cisco ONS 15540 ESPx chassis hold processor cards. The processor cards support redundancy and online insertion and removal. In a redundant system, the processor cards monitor each other using the Ethernet backplane and signals. The processor card monitors the fan assembly operation and airflow temperature. (See Figure 1-3.) During a fan failure or an out-of-temperature range condition, the processor card activates an alarm. See Table 2-2 on page 2-34 for fan assembly status.
Figure 1-3 Processor Card
Processor cards manage communication functions for the system. The cards monitor all modules in the chassis and determine the state of the system. Each module determines its state from feedback at various system monitoring points. The processor generates clocking to all the modules and some additional components in the system.

Note
Management Ports
The console port is a female data communications equipment (DCE), DB-25 receptacle used for connection to a console terminal or modem. Table 1-3 lists the console port pinouts.
The auxiliary port is a female RJ-45 receptacle used for connection to a modem. A three inch RJ-45 cable ships with the processor card for use with the auxiliary port. This cable is necessary for proper use of the auxiliary port. Attach this cable to the auxiliary port before attaching your own cables to the auxiliary port using the proper coupler. See Table 1-4 for the auxiliary port pinouts on the processor card.
Alarms
The processor generates three alarm signals: critical, major, and minor. (See Table 1-5.) These signals generate visual and audible alarm signals to the backplane, where they are connected to two DB-9 connectors that can be connected to a central telco alarm panel. LEDs on the processor card front panel display the status of the critical, major, and minor alarm signals, plus the status of alarm cutoff (ACO) and history conditions.
Push-button switches on the front panel provide for the alarm cutoff and history clear functions. (See Table 1-5.)
Note
Flash SIMM
The processor card Flash SIMM is a 16 MB, 80-pin SIMM that contains a compressed Cisco IOS image that is loaded and executed automatically by ROMMON upon powerup.
Flash PC Card Slots
The processor card has two Flash PC Card slots that are accessible from the front panel. Either slot can be a memory or an I/O device.
The Flash PC Cards are typically used to copy system images and save standard configurations. Flash PC Cards are a type of Flash memory that provide expanded file storage for your system. Flash PC Cards, unlike the onboard Flash SIMM (bootflash), are not required for the operation of the system.
Note
Table 1-6 lists the Flash PC Card slot LEDs on the processor faceplate and what the conditions indicate.
Table 1-6 Flash PC Card Slot LEDs

NMI Clear
A recessed push button, labeled NMI CLR, is accessible through the faceplate to clear an NMI (nonmaskable interrupt).
Note
NME Interface
The NME (network management Ethernet) interface supports 10-Mbps or 100-Mbps UTP (unshielded twisted pair) ports. This RJ-45 interface supports full-duplex or half-duplex connections.
The NME port on the processor card is a management port that allows multiple simultaneous Telnet or SNMP network management sessions. The Ethernet port on the processor card does not route or bridge traffic to other Ethernet ports on the Cisco ONS 15540 ESPx. This Ethernet port is a management port only and cannot be configured as a routing port.
Table 1-7 describes the LEDs used to confirm and troubleshoot the operation of the NME interface. The LEDs on the processor faceplate indicate the status of the NME interface.
Mux/Demux Motherboards and Mux/Demux Modules
The optical mux/demux motherboards occupy slots 0 and 1 of the Cisco ONS 15540 ESPx chassis. The chassis uses one optical mux/demux motherboard for unprotected operation or two per system for protected operation. The chassis supports the following mux/demux motherboards:
•
•
Each Cisco ONS 15540 ESPx mux/demux motherboard can accept up to four 4-channel or 8-channel mux/demux modules or one 32-channel mux/demux module. The modular mux/demux motherboards are available with or without OSC (optical supervisory channel) and can be populated according to user needs.
There are three types of mux/demux modules available:
•
•
•
Up to four 4-channel or 8-channel optical add/drop mux/demux modules can be installed in a mux/demux motherboard. Each module can multiplex and demultiplex a band of 4 or 8 channels, for a maximum of 32 channels. Channels not filtered are passed on to the next mux/demux module. (See Figure 1-6.)
Figure 1-6 4- and 8-Channel OADM Modules with OSC
One 32-channel terminal mux/demux module can be installed in slot 0 or 1 of the Cisco ONS 15540 ESPx chassis. The 32-channel terminal mux/demux module is equipped with OSC, input/output, and monitoring ports that use MU connectors. The remaining 8 ports that connect to the transponder modules use MTP connectors. The OSC is a dedicated, full duplex communication ITU-T DWDM channel for in-band management traffic. The input/output ports are trunk connections used to connect to the external fiber trunks. Monitoring ports use a one percent tap coupler (20 dB) for both the mux and demux sides and also allow you to non-obtrusively connect an OSA (optical spectrum analyzer) to monitor the incoming or outgoing DWDM signals.(See Figure 1-7.)

PSMs
The PSM (protection switch module) provides trunk fiber protection for Cisco ONS 15540 ESPx systems configured in point-to-point topologies. The PSM sends the DWDM signal from the mux/demux modules to both the west and east directions. It receives both the west and east signals and sends one to the mux/demux module. When a trunk fiber cut occurs on the active path, the PSM switches the received signal to the standby path. The PSM can protect up to 32 data channels and the OSC.
The PSM also has an optical monitor port for testing the west and east receive signals. This port samples 10 percent of these signals, which can be monitored with an optical power meter.
One PSM can be installed in any slot of a mux/demux motherboard on the Cisco ONS 15540 ESPx chassis.
The PSM has the same dimensions as the OADM channels used in the Cisco ONS 15540 ESPx. The front panel has four dual MU connectors, and the module internally consists of two boards interconnected through a board-to-board right angle connector. One board (called the generic optics module) contains the optics and sensitive analog circuitry, and the other board contains the logic and system interface board. (See Figure 1-8.)

Table 1-10 lists the LEDs on the 2.5-Gbps line card motherboard faceplate, their default conditions, and what the conditions indicate.
Table 1-11 lists the LEDs for the 10-Gbps line card motherboard.
Transponder Modules
In the transponder module, the client signal is converted to an ITU-compliant wavelength, which is cross-connected over the optical backplane to the mux/demux modules. You can populate the line card motherboard subcard slots with as few or as many transponder modules as required (up to 32) to support the desired number of client signals or data channels.
The Cisco ONS 15540 ESPx supports four types of interface transponder modules:
•
•
•
•
SM Transponder Modules
SM transponder modules have fixed, non-pluggable transceivers for the single client interface. SM transponder modules accept SM client signals on the 1310-nm wavelength through an SC connector and support client signal clock rates ranging from 16 Mbps to 2.5 Gbps.
MM Transponder Modules
MM transponder modules have fixed, non-pluggable transceivers for the single client interface. MM transponder modules accept both SM client signals and MM client signals on the 1310-nm wavelength through an SC connector and support client signal clock rates ranging from 16 Mbps to 622 Mbps.
Type 2 Extended Range Transponder Modules with SFP Optics
The Type 2 extended range transponder modules with selectable SFP optics support different protocol rates. (See Figure 1-11.)

10-GE Transponder Module
The 10-GE transponder module is double the size of the 2.5-Gbps transponder module and requires a special 10-Gbps line card motherboard. You can install up to two 10-GE transponder modules in a 10-Gbps line card motherboard. Each transponder supports one client side and one trunk side interface. The client side is a short-reach 1310-nm interface and the trunk side interface is an ITU grid compliant 15xx-nm long-reach interface. The transmitter supports a 1260-nm to 1355-nm wavelength range. The 10-GE transponder module is available in 32 versions, one for each of the 32 ITU channels it supports.
The 10-GE transponder module is not protocol independent; it supports the 802.ae specification for 10GBASE-LR interfaces. (See Figure 1-15.)

Table 1-16 lists the LEDs on the 10-GE transponder module faceplate and what the conditions indicate.
Cable Management Tray
The cable management tray is a fiber optic cable management guide that is installed over the fan assembly after you rack-mount the chassis. (See Figure 1-17.) The tray attaches to the rack but flips up if the fan assembly should need replacement. Cables are guided through the clips of the cable fanning tray and into and through the inside of the tray to their destination. The cable management tray ships with a cover that can be removed when you are cabling the Cisco ONS ESPx. For installation information for the cable management tray, see the "Mounting the Chassis" section on page 2-3.
Figure 1-17 Cisco ONS 15540 ESPx Cable Management Tray and Cover
Another cable management guide is available for the processor card cables and is installed on the upper part of the chassis above the line card slots. (See Figure 1-18.)
Figure 1-18 Top Cable Management Guide
Cross Connect Drawers
The cross connect drawers provide extra flexibility when provisioning channels. The cross connect drawer is a separate unit supporting 8 channels for a total of two channel bands in a protected system. The system is expandable in channels of 8. To cross connect 16 channels, use two cross connect drawers. To cross connect 32 channels, use four cross connect drawers with two cable storage drawers. See Figure 1-1.
Table 1-17 lists the equipment you need if you are using the cross connect drawer in a protected system using line card motherboards with splitter. Table 1-18 lists the equipment needed if you are using the drawer system in an unprotected system using line card motherboards without splitter.
