Installing the Cisco NCS 4216
SUMMARY STEPS
1. Disconnect any cables attached to the ports on the module.
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.
3. Loosen the two captive installation screws on the module you plan to remove from the chassis.
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.
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.
6. Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another
slot.
7. Install blank module filler plates (Cisco part number A90X-RSPA-BLANK-W) in empty slots, if any.
DETAILED 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
Note
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.
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 A90X-RSPA-BLANK-W) 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
Hot-Swapping an RSP Module
The Cisco NCS 4216 provides a feature that allows you to remove and replace a redundant RSP module
without powering down the router. This feature, called hot-swapping or OIR, allows you to remove and replace
a redundant module without disrupting router operation.
When two redundant modules are installed in the router, only one of the modules is active. The other one runs
in standby mode, ready to take over processing if the active module fails.
