Step 1

Follow the steps for removing the fan tray (if installed) from the chassis.

Step 2

Remove the dummy cover from the fan tray.

Step 3

Slide the dust filter onto the fan tray.

Step 4

Insert the dummy cover on the fan tray to secure the filter within the chassis.

Step 5

Follow the steps to install the fan tray in the chassis.


Removing the Dust Filter

Remove the dust filter for a replacement.


Note


  • The dust filter is a single-use component.

  • Use the dust filter (A903-FAN-F) within 6 months of buying as the shelf or storage life is less than 6 months. The ideal storage condition for a filter is a cool, dry, and dark environment. Surroundings that adversely affect the dust filter are high heat, humidity at high temperatures, and ultraviolet light.


Dust Filter Maintenance

A periodic health check of the filter, every three months based on the level of dust in the environment, helps in avoiding over clogging of the filters and provide a better life. This product's filter is used as a single-use component. If the product is installed in a controlled environment, check and replace the filter every three months, otherwise replace the filter every month.

Procedure

Step 1

Remove the dummy cover from the fan tray.

Step 2

Remove the dust filter from the fan.

Note

 
The filter can be accessed by pulling the pull tab by using fingers or pliers.

Step 3

Slide the replacement dust filter onto the fan tray

Step 4

Insert the dummy cover onto the fan tray to secure the filter within the chassis.


Removing and Replacing the Fan Tray

The fan tray supports online insertion and removal (OIR). There is no need to power down the Cisco NCS 4206 to remove or replace the fan tray. However, there is a finite time to replace the fan tray. This time depends upon the specific RSP and fan tray combination and also the ambient temperature. The following table provides the time interval for replacing the fan tray. At higher ambient temperatures, the replacement time is lower.


Note


If a fan tray is removed and not replaced within the stipulated time the system will automatically power-off. If the system is powered with PSUs other than 900W DC or 1200W AC and if the system is powered off, then the system should be completely powered off for 30 seconds with all the PSU in the system simultaneously, and then turned on for the system to power on.

Note


If the fan tray is removed and not replaced within the stipulated time, then the system will automatically power off. If the system is powered off, the AC or the DC input should be turned off for at least 30 seconds for all the PSU in the system simultaneously, and then turned on for the router to power on.

Caution


To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize after the fan tray has been replaced.


Follow these steps to remove and replace the fan tray on the Cisco NCS 4206:

Procedure


Step 1

Using a No. 2 Phillips screwdriver or your fingers, loosen the captive installation screw that secures the fan tray to the chassis. The figure below shows the front of the fan tray, including the captive installation screws.

Step 2

Grasp the fan tray handle with one hand and the outside of the chassis with the other hand. The figure below shows the front of the fan tray, including the handle.

Caution

 

The fans are exposed on the left side of the fan tray. Keep your fingers, clothing, and jewelry away from the fans. Always handle the fan tray by the handle.

Step 3

Pull the fan tray backward toward you no more than 1 inch to disengage it from the power receptacle on the midplane, as shown in the figure below.

When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Statement 258
Figure 17. Fan Tray Removal


Step 4

Wait at least 5 seconds to allow the fans to stop spinning. Then, pull the fan tray backward toward you and out of the chassis.

Note

 
As the fan tray slides out of the chassis, support the bottom of the fan tray with one hand and keep your other hand on the fan tray handle.

This completes the steps for removing the fan tray from the chassis.

To install the new fan tray, follow the steps in Installing the Fan Tray.


RSP Installation

Follow these steps on handling an RSP module in the Cisco NCS 4206:

Installing an RSP Module

To install an RSP module in the chassis, perform the following steps:

Procedure


Step 1

Choose a slot for the module. Ensure that there is enough clearance to accommodate any equipment that will be connected to the ports on the module. If a blank module filler plate is installed in the slot in which you plan to install the module, remove the plate by removing its 2 Phillips pan-head screws.

Step 2

Fully open both the ejector levers on the new module, as shown in the figure below.

Caution

 

To prevent ESD damage, handle modules by carrier edges only.

Step 3

Position the module in the slot. Make sure that you align the sides of the module with the guides on each side of the slot, as shown in the figure below.

Figure 18. Cisco NCS 4206 RSP Installation


Step 4

Carefully slide the module into the slot until the EMI gasket on the module makes contact with the module in the adjacent slot and both the ejector levers have closed to approximately 45 degrees with respect to the module faceplate.

Caution

 

If the top slot already has an RSP module installed, and you install a second RSP module in the slot below it, be careful not to damage the EMI gasket of the bottom RSP module against the ejector levers of the top RSP during insertion.

Step 5

While pressing down, simultaneously close both the ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate.

Step 6

Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5 in.-lb (.62 N-m).

Note

 
Make sure that the ejector levers are fully closed before tightening the captive installation screws.

Step 7

Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This step ensures that the EMI gaskets on all the modules are fully compressed in order to maximize the opening space for the new or replacement module.

Note

 
If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward the open slot, which reduces the size of the opening and makes it difficult to install the new module.

Note

 
Blank module filler plates (Cisco part number A900-RSPA-BLANK) should be installed in any empty chassis slots to keep dust out of the chassis and to maintain consistent airflow through the chassis.

Note

 
When installing the cabling to an RSP, we recommend that you leave a service loop of extra cabling sufficient to allow for fan tray removal.

Removing an RSP Module

Before you remove an RSP from the chassis, you should save the current configuration using the write {host file | network | terminal} command. This saves you time when bringing the module back online.

If the module is running Cisco IOS software, save the current running configuration by entering the copy running-config startup-config command.


Warning


Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Warning


Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051


To remove an RSP module, perform the following steps:

Procedure


Step 1

Disconnect any cables attached to the ports on the module.

Step 2

Verify that the captive installation screws on all the modules in the chassis are tight. This step ensures that the space created by the removed module is maintained.

Note

 
If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open slot, which in turn reduces the size of the opening and makes it difficult to remove the module.

Step 3

Loosen the two captive installation screws on the module you plan to remove from the chassis.

Step 4

Place your thumbs on the ejector levers and simultaneously rotate the ejector levers outward to unseat the module from the backplane connector.

Step 5

Grasp the front edge of the module and slide the module straight out of the slot. If the chassis has horizontal slots, place your hand under the module to support its weight as you slide it out from the slot. Do not touch the module circuitry.

Caution

 

To prevent ESD damage, handle modules by the carrier edges only.

Step 6

Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another slot.

Step 7

Install blank module filler plates (Cisco part number A900-RSPA-BLANK) in empty slots, if any.

Warning

 

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029


Installing the Wire Wrap Adapter

The wire wrap adapter is used to support the wire wrap interface for the BITS port on the RSP3 module. This adapter is plugged into the existing RJ-45 connector on the RSP3 module.

Figure 19. Wire Wrap Adapter


For information on pinouts, see Wire Wrap Adapter Pinouts.

Hot-Swapping an RSP Module

The Cisco NCS 4206 provides a feature that allows you to remove and replace a redundant RSP module without powering down the chassis. This feature, called hot-swapping or OIR, allows you to remove and replace a redundant module without disrupting chassis operation.

When two redundant modules are installed in the chassis, only one of the modules is active. The other one runs in standby mode, ready to take over processing if the active module fails.

When you remove or insert a redundant module while the chassis is powered on and running, the chassis does the following:

  1. Determines if there is sufficient power for the module.
  2. Scans the backplane for configuration changes.
  3. Initializes the newly inserted module. In addition, the system notes any removed modules and places those modules in the administratively shutdown state.
  4. Places any previously configured interfaces on the module back to the state they were in when they were removed. Any newly inserted interfaces are put in the administratively shutdown state as if they were present (but unconfigured) at boot time. If you insert the same type of module into a slot, its ports are configured and brought online up to the port count of the original module.

The chassis runs diagnostic tests on any new interfaces and the test results indicate the following:

  • If the tests pass, the chassis is operating normally.
  • If the new module is faulty, the chassis resumes normal operation but leaves the new interfaces disabled.
  • If the diagnostic tests fail, the chassis stops operating, which usually indicates that the new module has a problem in the bus and should be removed.

Interface Module Installation

The following sections describe the various tasks of associated with interface module installation on the Cisco NCS 4206.

Installing an Interface Module

Procedure


Step 1

Before inserting an interface module, make sure that the chassis is grounded.

Step 2

To insert the interface module, carefully align the edges of the interface module between the upper and lower edges of the chassis slot.

Step 3

Carefully slide the interface module into the chassis slot until the interface module makes contact with the backplane. The figure below shows how to install the interface module.

Figure 20. Inserting an Interface Module


Caution

 

Use the pull tab on the interface module only to insert and pull the card out straightly. Don’t use the pull tab to turn on its axis or bend it up or down, which can deform or damage the pull tab.

Figure 21. Using the Pull Tab
Use the pull tab on the interface module only to insert and pull the card out straightly.

Step 4

Tighten the locking thumbscrews on both sides of the interface module. The recommended maximum torque is 5.5 in.-lb (.62 N-m).

Step 5

Connect all the cables to each interface module.


What to do next


Caution


Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can deform or damage the handles.


Removing an Interface Module

Procedure


Step 1

To remove an interface module, disconnect all the cables from each interface module.

Step 2

Loosen the locking thumbscrews on both sides of the interface module.

Step 3

Slide the interface module out of the slot by pulling on the handles. If you are removing a blank filler plate, pull the blank filler plate completely out of the slot using the captive screws.


Hot-Swapping an Interface Module

The Cisco NCS 4206 router provides a feature that allows you to remove and replace an interface module without powering down the router. This feature, called hot-swapping or OIR, allows you to remove and replace a redundant module without disrupting chassis operation.

Use the following guidelines when performing an OIR on an IM:

  • Avoid inserting a new IM during bootup until the active and standby RSPs have reached an OK state.
  • When inserting multiple IMs into the chassis, wait until each IM reaches an OK state before inserting the next IM.

When you remove or insert a redundant module while the chassis is powered on and running, the chassis does the following:

  1. Determines if there is sufficient power for the module.
  2. Scans the backplane for configuration changes.
  3. Initializes the newly inserted module. In addition, the system notes any removed modules and places those modules in the administratively shutdown state.
  4. Places any previously configured interfaces on the module back to the state they were in when they were removed.

The runs diagnostic tests on any new interfaces and the test results indicate the following:

  • If the tests pass, the is operating normally.
  • If the new module is faulty, the resumes normal operation but leaves the new interfaces disabled.
  • If the diagnostic tests fail, the stops operating, which usually indicates that the new module has a problem in the bus and should be removed.

Caution


To avoid erroneous failure messages, note the current configuration of all interfaces before you remove or replace an interface module, and allow at least 2 minutes for the system to reinitialize after a module has been removed or replaced. This time is recommended in order to allow for synchronization between components within the interface module and for synchronization with the standby RSP.



Note


Always refer to Interface Module compatibility matrix tables in the Data Sheet before you swap any IM.

Installing the Power Supply

The Cisco NCS 4206 provides the choice of two different power supplies:

  • DC power
    • 900 W DC power: –40VDC to –72VDC

The DC power supply provides option to connect with two different sources (dual feed); positive (+) and negative (-) are marked on the PSU terminals.

Each power supply provides a dual primary input power connection.


Caution


The power supply must be wired before plugging the power supply in the chassis. Ensure the branch circuit breaker is turned off. Only after installing the power supply in the chassis, should the branch circuit breaker be turned on. The branch circuit breaker must be turned off before unplugging the power supply.Read the installation instructions before connecting the system to the power source. Statement 10



Caution


Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can deform or damage the handles.


Preventing Power Loss

Use the following guidelines to prevent power loss to the chassis.

  • To prevent loss of input power, ensure that the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and breakers.
  • In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems like the Cisco NCS 4206, which can have substantial current draw fluctuations due to bursty data traffic patterns.

Use the information in the DC Power Specifications section to estimate the power requirements and heat dissipation of a Cisco NCS 4206 based on a given configuration. Determining power requirements is useful for planning the power distribution system.

Power Connection Guidelines

This section provides guidelines for connecting the Cisco NCS 4206 power supplies to the site power source.


Warning


Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 213



Warning


The plug-socket combination must be accessible at all times because it serves as the main disconnecting device. Statement 1019



Warning


This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045


Guidelines for DC-Powered Systems

Basic guidelines for DC-powered systems include the following:

  • Each chassis power supply should have its own dedicated input power source. The source must comply with the safety extra-low voltage (SELV) requirements in the UL 60950, CSA 60950, EN 60950, and IEC 60950 standards.
  • The circuit must be protected by a dedicated two-pole circuit breaker. The circuit breaker should be sized according to the power supply input rating and local or national code requirements.
  • The circuit breaker is considered the disconnect device and should be easily accessible.
  • The system ground is the power supply and chassis ground.
  • Do not connect the DC return wire to the system frame or to the system grounding equipment.
  • Use the grounding lug to attach a wrist strap for ESD protection during servicing.

Connecting a Management Ethernet Cable

When using the Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates in auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the Auto-MDI/MDI-X feature. The port automatically senses a crossover or straight-through cable and adapts to it.

However, when the Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through command-line interface (CLI) commands, the port is forced to MDI mode.

When in a fixed-speed configuration and MDI mode:

  • Use a crossover cable to connect to an MDI port
  • Use a straight-through cable to connect to an MDI-X port

Warning


To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Management Ethernet ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.


Installing and Removing SFP Modules

The Cisco NCS 4206 supports a variety of SFP modules, including optical and Ethernet modules. For information on how to install and remove SFP modules, see the documentation for the SFP module at https://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/installation/note/78_15160.html.

For information about inspecting and cleaning fiber-optic connections, see https://www.cisco.com/c/en/us/support/docs/optical/synchronous-digital-hierarchy-sdh/51834-cleanfiber2.html.


Caution


We recommend that you wait 30 seconds between removal and insertion of an SFP on an interface module. This time is recommended to allow the transceiver software to initialize and synchronize with the standby RSP. Changing an SFP more quickly could result in transceiver initialization issues that disable the SFP.

The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 1 and Type 3 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.


Patch Panel Connectors

The PANEL-48-1-DIN and PANEL-48-3-DIN provide 48 DIN 1.0/2.3 connectors on the front side of the patch panel. These connectors terminate to 75 ohm coaxial cable through the DIN plug.

The PANEL-48-1-RJ48 provide 48 RJ45 connector on the front side of the patch panel. These connectors terminate to 110 ohm T1/E1 cable through a RJ45 connector.

Patch Panel Cabling for Redundancy

You can connect the patch panels with the interface modules for redundancy, using the Y-cables. The Y-cable stub lengths are reduced, so that the cable does not exceed from the rack spacer. The Y-cables are numbered based on the different stub length. Cable lengths differ for even numbered and odd numbered slots in the chassis.

Connecting the Fan Tray Alarm Port

The fan tray includes an alarm port that maps to 4 dry contact alarm inputs.

The pins on the alarm port are passive signals and can be configured as Normally Open (an alarm generated when current is interrupted) or Normally Closed (an alarm is generated when a circuit is established) alarms. You can configure each alarm input as critical, major, or minor. An alarm triggers alarm LEDs and alarm messages. The relay contacts can be controlled through any appropriate third-party relay controller. The open/close configuration is an option controlled in IOS.


Warning


To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the alarm ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.


Only Pins 1, 2, 4, 6, and 8 are available for customer use. The remaining pins are for Cisco manufacturing test, and should not be connected. Use a shielded cable for connection to this port for EMC protection. See Troubleshooting for a summary of the pinouts on the alarm port .

Procedure


Step 1

Attach an RJ45 cable to the alarm port.

Step 2

Attach the other end of the RJ45 cable to the relay controller.
