Remove and Replace Cisco NCS 1004 Modules

This chapter describes the procedures to replace Cisco NCS 1004 modules.


Caution

All the modular slots in the NCS 1004 chassis should always be populated with respective modules (line-cards, controller, PSU & fan units). Empty line card slots to be populated with filler modules, which are shipped with the chassis. The replacement or upgrade of the modules (Online Insertion or Removal, OIR) to be performed only when the ambient temperature is below 30-degree C. The OIR of modules should be completed within five minutes to prevent overheating of the components.

Online Insertion and Removal of a Line Card

The Cisco NCS1004 controller unit provides a push button to initiate Online Insertion and Removal (OIR) during the upgrade or replacement of line cards. The same process is to be followed when a filler module is replaced with a line card. This button is used to prepare the system for the imminent loss of thermal efficiency due to the air leakage from the open slot (when the line card or filler card is removed from the chassis). The OIR button sets all fan units to maximum speed for 90 seconds which brings down the temperature of all internal components. After 90 seconds, the user can safely remove the line card or filler module from the chassis.


Caution

The OIR of procedure for line card or filler module to be performed only when the ambient temperature is below 30-degree C and should be completed within five minutes to prevent overheating of the chassis components.

Procedure

Step 1

Press the OIR button; refer the following image.

The ATT LED on the controller unit starts blinking and the fan units are set to the maximum speed.

Caution

 

Wait for 90 seconds before proceeding.

Step 2

After the blinking stops, remove the line card from the chassis and replace it with another line card. For the detailed line card installation procedure, see Line Card Installation.

Fan units continue to run at maximum speed, until the new line card module is inserted back. After the new line card is detected, the speed of the fan units return to their normal speed.

Note

 
If the filler card or line card is not removed from the chassis within 10 seconds after the ATT LED stops blinking, the fan units return to the normal speed.

  • Remove the protection covers, fasteners and lugs, in case of a DC power supply.

Procedure

Step 1

Press the locking latch towards the left to release the lock.

Remove and Replace Controller

This procedure has details about removing and replacing the controller.

Procedure

Step 1

Using a Torx screwdriver, unfasten the two screws on the controller.

Step 2

Using the handle with one hand, and supporting the controller with the other, gently remove the controller from the slot.

What to do next

For replacing the controller, see Install Controller.

Remove and replace the battery in the controller

Use this task to remove and replace the controller battery.

Before you begin

Ensure you have these tools and equipment

  • #1 Phillips-head, Hex 5.5 torque screwdriver

  • Plastic spudger/pry tool

  • Plastic or ceramic tweezers

  • Electrostatic discharge (ESD) strap or other grounding equipment such as a grounded mat

  • Replacement Battery – Choose any one from the options:

    • CR-2032L/BN — Panasonic

    • 06032 101 501 — Varta Microbattery Inc.

    • 100272 — Renata


Caution

Handle them only by carrier edges and use an electrostatic discharge (ESD) wrist-strap or other grounding device to avoid damage.


Warning

Ensure the system is shut down and power is removed before proceeding.

There is danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions.

Procedure

Step 1

Remove the PCB assembly from the controller.

  1. Remove the face plate by unscrewing the seven M3x0.5x3 mm screws with the #1 Phillips-head screwdriver.

  2. Remove the battery from the socket using the plastic spudger tool to push against the spring and release the battery.

Step 3

Install the new RTC battery.

  1. Identify the battery polarity.

    The positive side of the battery has the "CR2032" text and a plus sign (+) on it, and the negative side is flat.

  2. Insert the battery at a slight angle around 30-degrees to the holder's opening, with the negative flat side facing the internal lower spring contact.

  3. Gently push the battery inward toward the spring, then press down until it clicks securely into place under the retaining tabs.

  4. Ensure the battery is seated snugly and correctly. The positive side of the battery should be facing the retainer clip/tab when installed in the vertical holder.

Step 4

Reassemble the controller unit.

  1. Mount the PCB assembly back onto the carrier, ensuring the Interposer connector locks in place.

  2. Attach the protection cover by tightening the Hex nuts and screws to a torque of 5.5 ± 0.5 in.lb where specified.

  3. Turn the controller and tighten the two M2.5x0.45x8 mm screws using the #1 Phillips-head screwdriver to a torque of 3.3 ± 0.3 in.lb.

  4. Reattach the face plate by tightening the seven M3x0.5x3 mm screws using #1 Phillips-head screwdriver to a torque of 3.3 ± 0.3 in.lb.

    Note

     

    Fasten the side screws of the face plate first, followed by the bottom screws, to align the connector location.
The new RTC battery is correctly installed and seated. The controller is ready for reassembly and power-up.

What to do next

  • Power on the controller and verify that it recognizes the new RTC battery and no battery errors are reported.

  • Safely dispose the old battery according to local practices.
