Installing the Cisco NCS 4216
Dust Filter Maintenance
A periodic health check of the filter, every 3 months based on the level of dust in the environment helps in
avoiding over clogging of the filters and provide better life. The product's filter may be used as a single use
or reused depending upon the local deployment needs. If reuse of the filter is prohibited, it may be replaced
every six months with PID (A907-FAN-F=) or equivalent.
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
4216 to remove or replace the fan tray. However, the router will shut down if the fan tray is removed from
the chassis for more than 90 seconds at 25º C due to thermal overload condition. Once the thermal overload
condition is absent, the system attempts to power up automatically, if the Fan tray is re-inserted and the system
temperature is within limits. Approximately at 25º C the system powers back in 2 minutes.
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.
Dust Filter Maintenance
Note
Do not introduce body parts or objects in the fan tray slot when installing or removing the fan tray module.
Exposed circuitry is an energy hazard.
Caution
The router can stay active for up to 60 seconds if the temperature is below the ambient limit. However, in the
event of an overtemperature alarm, the router can shut down in less than 60 seconds. In the event of a critical
temperature alarm, the router shuts down immediately.
Caution
To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize after the fan tray
has been removed or replaced.
Follow these steps to remove and replace the fan tray on the Cisco NCS 4216:
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 following figure shows the front of the fan tray, including the captive installation

OIR TimeTemperature º C at 1800 mSerial Number
30 seconds31º C to 40º C2
Step 1 Choose a slot for the module. Make sure 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
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.
To prevent ESD damage, handle modules by carrier edges only.
Installing the Cisco NCS 4216

Installing the Cisco NCS 4216
Figure 22: Cisco NCS 4216 RSP Installation
Installing an RSP Module
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.

Removing an RSP Module
Installing the Cisco NCS 4216
Caution
Blank module filler plates (Cisco part number A90X-RSPA-BLANK-W) 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 router, you should save the current configuration on a TFTP server or
an external USB flash drive, using the copy running-config {ftp | tftp | bootflash:} 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 (see Cisco NCS 4216 RSP Installation figure ) 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.
