Remove and Replace the Cisco NCS 1020 Modules

This chapter describes the tasks to remove and replace Cisco NCS 1020 modules.


Note

In this chapter, "front fan tray" refers to the NCS1010-FAN tray, "rear fan tray" refers to the NCS1020-FAN tray, and "filler fan tray" refers to the NCS1020-FAN-BLANK tray. Front fan trays and rear fan trays contain a different set of fan units. Slots for the front fan trays and rear fan trays are not interchangeable.


Note

In this chapter, "Type 1 line card" refers to "NCS 1010 line card" and "Type 2 line card" refers to "NCS 1014 line card".

Caution

Always populate the modular slots in the Cisco NCS 1020 chassis with respective modules (line card, controller, PSU, and fan trays). Perform the replacement or upgrade of the modules (Online Insertion or Removal (OIR)) only when the ambient temperature is below 30-degree C. Complete the OIR of modules within five minutes to prevent overheating of the components.

Remove and Replace the Type 2 Line Card

Use this procedure to remove and replace the type 2 line card in the Cisco NCS 1020 chassis.


Note
This procedure also applies to the type 2 filler card removal.

Caution

Perform the removal and replacement procedure for a type 2 line card or filler card only when the ambient temperature is below 30-degree C (80-degree F). Complete the procedure within five minutes to prevent overheating of the chassis components.

Procedure

Step 1

Using the T-15 six lobe/slot screwdriver, loosen the captive screws available in the type 2 line card.

Step 2

Holding the fiber management bracket with one hand and supporting the type 2 line card with the other, pull it away from the slot.

Caution

 

Use the fiber management brackets only for pulling out or pushing in the type 2 line cards or filler cards. Do not use the fiber management brackets to carry the cards. Always support the type line card or filler card at the bottom with your hand.

What to do next

Install the Type 2 Line/Filler Card

Remove and Replace Chassis Door Foam Air Filters

The air filter removes dust from the fan that is drawn into the chassis by the fan trays. If the air filters are damaged, dirty, or clogged with dust, replace them with new air filters. Failure to replace a compromised air filter can result in insufficient fan circulation through the chassis and temperature-related environmental alarms.


Note

First inspection of the air filter must be performed six months after the first installation of the air filter. Air filters must be inspected every three months after the initial six-month inspection and replaced if found to be dirty. Do not reuse the cleaned air filters. Replace them with a new air filter. We recommend having spare air filters in stock.

The front doors come with preinstalled air filters (NCS1020-DR-FTF=). If air filters need a replacement, use this procedure.

Procedure

Step 1

Remove the two quarter turn fasteners from the front door.

Figure 7. Replace Air Filter

Step 2

Install the new door filters on both the front doors.

Step 3

Tighten the two quarter turn fasteners back on the doors.

Step 4

Store the door frames in a package.

Remove and Replace the Front Fan Tray

Use this procedure to remove and replace a front fan tray in the Cisco NCS 1020 chassis.


Caution

Online Insertion and Removal (OIR) duration for the fan tray unit at 30-degree C (80-degree F) ambient temperature, is five minutes.

Only one fan tray should be removed at a time. Removing both fan trays simultaneously leads to overheating and may result in an unexpected system shutdown.

Procedure

Step 1

Loosen the captive screws (one on the left side and the other on the right side) using a screwdriver.

Step 2

Using the handle, pull the fan tray out of the chassis.

Figure 8. Removing the Front Fan Tray

Step 3

Repeat Step 1 and Step 2 to remove the second fan tray.

What to do next

To replace a front fan tray, see Install the Front Fan Trays.

Remove and Replace the Type 1 Line Card


Note
This procedure also applies to the type 1 active and passive filler card removal.

Use this procedure to remove and replace the type 1 line card in the Cisco NCS 1020 chassis.

Before you begin


Caution

  • Perform the removal and replacement procedure for the line card only when the ambient temperature is below 30-degree C and complete it within five minutes to prevent overheating of the chassis components.

  • Ensure that you perform the removal and replacement of the fan trays and line card within the five minutes of time limit.

  • As the fan trays draw power through the line card, you must complete the line card replacement before installing the fan trays on top of it.

Procedure

Step 1

Loosen the captive screws available in the type 1 card handles.

Step 2

Pull the handles out of the type 1 line card, and gently remove the card from the chassis.

Caution

 

Use the handles only to push and pull out the type 1 line card from the chassis. Do not use the handles to carry the type 1 line card. To prevent any accidental drop, support the top and bottom of the type 1 line card with your hand while you remove or insert it.

What to do next

To replace the type 1 line card, see Install the Type 1 Line/Filler Card.

Wipe Data in Disk Using Secure Erase

When NCS 1020 becomes faulty, contact TAC to open a Return Material Authorization (RMA) request. Before opening an RMA request, you can securely erase data on NCS 1020 disks using the Secure Erase feature.


Warning

Use this procedure only during RMA.

Before you begin

  • The NCS 1020 unit that is planned for RMA must be taken out of the data center and the network. You must access NCS 1020 only using the console port.

  • You must perform the RP cold reload for the successful CPU disk wipe.

  • You must perform the chassis cold reload for the successful Chassis disk wipe.

Procedure

Step 1

When NCS 1020 boots during RP cold reload or chassis cold reload, the following message appears.
