Installing the Chassis Ground Connection

Perform the following procedure to ground the Cisco NCS 4206 using a 2-hole lug and the corresponding
mounting point. Most carriers require a minimum 6 AWG ground connection. Verify your carrier’s requirements
for the ground connection.
Step 1 If your ground wire is insulated, use a wire-stripping tool to strip the ground wire to 0.5 inch ± 0.02 inch (12.7 mm ±0.5
mm) ( as shown in the figure below ).
Figure 13: Stripping a Ground Wire
Step 2 Slide the open end of your 2-hole ground lug over the exposed area of the ground wire.
Step 3 Using a crimping tool (as specified by the ground lug manufacturer), crimp the ground lug to the ground wire as shown
in the figure below.
Figure 14: Crimping a Ground Lug onto the Ground Wire
Step 4 Use a Phillips head screwdriver to attach the 2-hole ground lug and wire assembly to the chassis with the 2 pan-head
Phillips head screws. For a 19-inch EIA rack, attach the 2-hole ground lug to the rear of the router.
Step 5 Connect the other end of the ground wire to a suitable grounding point at your site.

how to orient the fan tray.
Figure 15: Installing the Fan Tray
Step 2 Guide the fan tray into the chassis until it is fully seated.
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.
Caution
When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling sufficient
to allow for fan tray removal.
Note
Step 3 Secure the fan tray to the chassis using the attached captive installation screws. The recommended maximum torque is
5.5 in.-lb (.62 N-m).
This completes the procedure for installing or replacing the fan tray in a Cisco NCS 4206.

Installing the Dust Filter

Removing the Dust Filter
Remove the dust filter for a replacement.
• 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.
Note
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.
Step 1 Remove the dummy cover from the fan tray.
Step 2 Remove the dust filter from the fan.
The filter can be accessed by pulling the pull tab by using fingers or pliers.
Note
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.
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.

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.
Note
To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize after the fan tray
has been replaced.
Caution
Follow these steps to remove and replace the fan tray on the Cisco NCS 4206:
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.

Handle2Captive installation screw1
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.
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.
Caution
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.

Removing and Replacing the Fan Tray

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

RSP Installation

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

Installing an RSP Module

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.
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
Warning
To remove an RSP module, perform the following steps:
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.
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.
Note
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.
To prevent ESD damage, handle modules by the carrier edges only.
Caution
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.
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
Warning
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.

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.
Installing the Cisco NCS 4206

Installing the Cisco NCS 4206
Hot-Swapping an RSP Module

• 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
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
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
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.
