Replace Chassis Door Foam Air Filters


Note
In general, we recommend that you inspect the air filter every 3 months and replace. Air filters are consumable items and must be ordered separately by customers. Customers may contact TAC for assistance in identifying the correct air filter PID to order. We recommend having spare air filters in stock.

The front doors come with pre-installed air filters (8818-FILTER, 8812-FILTER, 8808-FILTER, or 8804-FILTER). If air filters need a replacement, follow this procedure.

Procedure

Step 1

Remove the two quarter turn fasteners from the front door as shown.

Figure 1. 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.

Provision of Grace Period Before Route Processor Shutdown from Ejector Lever

Release Information

Feature Description

Provision of Grace Period Before Route Processor Shutdown from Ejector Lever

Release 7.3.1

Unlatching the ejector lever of any card that is in operational state, triggers a graceful shutdown of that card.

With this release, the active RP card is enabled with a grace period of 15 seconds before it shuts down. In the event the ejector lever is unlatched, or for any other reason, you have 15 seconds to relatch the ejector lever and return the active RP back to its operational state.

The hw-module ejector close wait command is introduced for this feature.

Earlier, unlatching the ejector lever from the latch lock immediately would trigger a graceful shutdown of the Route Processor if the card is in the operational state. However, after enabling this feature, the active RP card has a grace period of 15 seconds before shutdown.

If the ejector lever is latched back within this grace period, then the card returns to the operational state. This feature, therefore, provides the option of closing the ejector lever without triggering a shutdown. This feature is especially useful when an ejector lever is accidentally unlatched.

This feature is supported only on a route processor card.

If the ejector is unlatched when card is in a status other than operational state then the grace period feature will not be supported.


Caution

When you enable this feature, do not remove the RP during the 15-second grace period. Remove the RP only in either of the following two ways:

  • Allow the RP to shut down after the 15-second grace period, then remove the RP.

  • Close the ejector lever within the 15-second grace period, then remove the RP gracefully (shutdown the RP first) or ungracefully.

LED Status

The RP status LED blinks twice with one second gap until the grace period is over.

Enabling Grace Period Before Shutting down a RP Card

This task explains how to enable grace period before shutting down a RP card:

Router(config)# hw-module ejector close wait
Router(config)# commit
Router(config)# end

The configuration is applied only on the active RP.

Use the no form of the command to remove the grace period configuration. 

Router(config)# no hw-module ejector close wait

Replace a Route Processor Card

The Cisco 8818, Cisco 8812, Cisco 8808, and Cisco 8804 Routers support OIR of Route Processor (RP) cards.

The router supports up to two redundant Route Processor cards (8800-RP). When two Route Processor cards are installed in the router, one acts as an active card and the other as the standby card. When the active Route Processor card is removed, the router automatically makes the standby Route Processor card active. If the router has only one Route Processor card that is installed, a new Route Processor can be installed in the empty Route Processor slot during operation.


Warning

Statement 1029—Blank Faceplates and Cover Panels

Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, 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.


Note

Opening the ejector levers of an installed RP card causes the RP card to shut down even when the captive screws are screwed in. To reboot the RP card, users must do one of the following:

  • Remove and reinsert the RP card and close the ejector levers.

  • Close the ejector levers and reload the card using the reload location <rack>/<{RP0 | RP1}> force command.

Caution

Unlatching the right ejector lever, so that it disengages from the latch lock (Callout 1 in the previous figure) triggers graceful shutdown of the Route Processor (RP) if the card is up. If the card shuts down, then wait for the RP LED to turn off before proceeding.

Moving the latch to the side doesn't disengage the latch from the lock. This is a safeguard mechanism if an operator-initiated shutdown of the route processor hasn't been performed before opening the levers. The ejector open will be logged.

  1. Open the packaging for the new RP card. Inspect the card for damage, and verify that the card is the same type as the other RP card installed in the chassis. Carefully inspect the backplane connector of the chassis and RP.


    Note

    If the card is damaged, alert the Technical Assistance Center (TAC).

  2. If you're installing the card in an empty slot, remove the blank card that is already in that slot by unscrewing its captive screw and pulling it out of the slot.

  3. If you're replacing a card that is currently in the chassis, remove the existing card from the chassis by following these steps:

    1. Run the shutdown location 0/ {RP0 | RP1} command in EXEC mode, which gracefully shuts down the Route Processor module to prevent any of the file systems from being corrupted.

    2. Verify that the Route Processor Status LED for the slot that you specified turns to Amber. Also, you can use the show platform command to verify that the status of the card is SHUT DOWN.

    3. Disconnect the cables from the card.

    4. If there are any external drives attached to the card through its USB ports, detach those drives.

    5. Loosen the two captive screws (one on each side of the RP) until the screws are no longer in contact with the chassis.

    6. Slide the latch on each of the ejector levers outwards from the lever center (see Callout 1 in the following figure).


      Attention

      This action disengages the ejector levers from the faceplate.
      Figure 3. Remove Route Processor Card from Chassis

    7. Pull to rotate the levers away from the front of the card (see Callout 2 in the previous figure).

      The card unseats its connectors from the midplane and moves slightly out of the chassis.

    8. Use one hand to hold the front of the card. Place your other hand under the card to support its weight. Pull the card out of the chassis, and set it on an antistatic surface or inside an antistatic bag.


      Note

      While performing OIR of the card, wait for 30 seconds before inserting the same or new card in the same slot. This allows the card to boot properly and reach an operational state.

Install a New 8800-RP Card

To install a new card, follow these steps:

  1. If any of the ejector levers are in closed position, slide the latch on the ejector lever outwards from the lever center. Then, pull to rotate the lever away from the front of the card.

    This action opens the lever so that the card can be fully inserted into the slot.

  2. Hold the front of the card with one hand and place your other hand under the card to support its weight.


    Note

    Ensure that you hold the route processor card parallel to the chassis while inserting it. Inserting the route processor card at an angle may damage the card's PCB.

  3. Align the back of the card to the guides in the open Route Processor slot and slide the card all the way into the slot.

    The card stops when its front is about 0.25 inches (0.6 cm) outside the front of the chassis.

  4. Rotate the levers firmly all the way to the front of the chassis. Then firmly push the tip of the lever towards the faceplate until the latch hook locks in place behind the faceplate. You may hear a click or see the latch engage. (See Callout 1 in the following figure.)

    Ensure that the other end of both levers engages behind the latching slot on the faceplate so that the card fully seats onto the connectors on the midplane.


    Note

    To confirm that the card is installed properly, pull the black tip of each ejector lever lightly, and ensure that the lever doesn't pop out.

    Figure 4. Install Route Processor Card into Chassis

  5. Screw in the two captive screws to secure the card to the chassis. Tighten the screws to 8 in-lb (0.9 N·m) of torque.

  6. Attach the cables to the card.

  7. Verify that the Route Processor card status LEDs turn on and appear green.

Replace a Line Card

The Cisco 8800 series routers can operate with one or more line cards. If there is at least one line card that is installed and operating in the chassis, you can replace another line card or install a new line card in an empty line card slot.

The Cisco 8800 series routers support OIR of line cards.


Note
You must install at least one route processor card when you power on the router.

Cisco 8800 series line cards use either buttons or latches to lock the ejector levers.

Watch Replace a Line Card (Video).

Replace or Install a Line Card - Ejector Levers with Buttons


Warning

Statement 1029—Blank Faceplates and Cover Panels

Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, 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.


Warning

Statement 1051—Laser Radiation

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.


Caution

  • Line cards have two ejector levers to release the card from the router. Use these levers to remove the line card and to seat the line card firmly in the router when you are installing the line card. The ejector levers align and seat the card connectors in the router. To avoid damaging card mechanical components, never carry a line card by the captive installation screws or ejector levers. Doing so can damage these components and cause card insertion problems.

  • Ensure that all the line card screws are fully tightened. Failure to properly tighten the line card screws may result in fabric links not coming up.

  • Rotate the ejector levers toward the faceplate past parallel until it stops. This ensures that the line card fully inserts when you install the line card.


Note

Opening the ejector levers of an installed line card causes the line card to shut down even when the captive screws are screwed in. To reboot the line card, you must do one of the following:

  • Remove and reinsert the line card and close the ejector levers.

  • Close the ejector levers and reload the card using the reload location <rack>/<line-card-slot> force command.

Procedure

Step 1

Open the packaging for the new line card and inspect the line card for damage. Carefully inspect the fabric connectors for damage.

If the line card is damaged, contact the Technical Assistance Center (TAC).

Step 2

If you are replacing a line card that is currently in the chassis, remove the existing line card from the chassis by following these steps:

  1. Run the shutdown location 0/ location/CPU0 command, which gracefully shuts down the line card.

  2. Verify that the Line Card LED for the slot that you specified turns off. Also, you can use the show platform command to verify that the status of the card is SHUT DOWN.

  3. Disconnect and label each of the interface cables from the line card.

  4. Loosen the two captive screws.

  5. Press the ejector buttons and the two ejector levers open in the direction as shown in the image below.

Replace a Fan Tray

You can remove a fan tray (8818-FAN, 8812-FAN, 8808-FAN, or 8804-FAN) to either replace it with another fan tray or to replace a fabric card located behind it.

The router uses four fan trays but it can operate with three fan trays while you replace one or remove one to replace one of the fabric cards behind the fan tray. When you remove one fan tray, the other fan trays speed up their fans to maintain the designed airflow.


Note

Fan trays marked with a blue dot have no impact on installation steps or airflow direction.

Note

To ensure adequate airflow and prevent overheating, do not operate the router with three fan trays for more than 10 minutes.

Caution
Never remove two fan trays at a time during operation, the router allows up to two minutes of operations before shutting down unless you replace the missing fan tray within that time. If the router senses an over temperature condition when multiple fan trays are removed, the shutdown can occur in less than two minutes.

To replace a fan tray, you must perform the following functions:

  1. Remove the fan tray.

  2. Install a fan tray.

Watch Replace a Fan Tray (Video).

Remove Fan Tray

Remove only one fan tray at a time during router operations. If you remove more than one fan tray at a time, the router shuts down within two minutes unless you replace the extra fan trays that you removed within that time.

Procedure

Step 1

Unscrew the four captive screws on the front of the fan tray until each screw is free of the chassis.

Step 2

Hold both handles on the front of the fan tray with both of your hands and pull the fan tray out of the slot.

Step 3

Set the fan tray on antistatic material or inside an antistatic bag.

Install Fan Tray

Before you begin

  • Fan tray slot is open in the chassis.

  • If you are replacing a fabric card behind the open fan tray slot, ensure that the fabric card replacement operation is completed.

Procedure

Step 1

Step 4

Slide the fan tray all the way into the slot until the front of the fan tray touches the chassis.

Make sure that the four captive screws on the front of the fan tray align with the four screw holes in the chassis.

Step 5

Screw in the four captive screws to secure the fan tray to the chassis. Tighten the screws to 8 in-lb (0.9 N·m) of torque.

Step 6

Verify that the fan tray STATUS LED turns on and becomes green, approximately within 20 seconds.

Replace Fabric Card


Warning

Statement 1079—Hot Surface

This icon is a hot surface warning. To avoid personal injury, do not touch without proper protection.


Note

The fabric card surfaces may reach temperatures exceeding 80°C (176°F). Removal and installation of the fabric card must be performed by a skilled individual. To avoid potential burns or injuries, always wear appropriate Personal Protective Equipment (PPE), such as heat-resistant gloves rated for a minimum of 100°C (212°F), when handling the fabric card.


Note

The Cisco 8800 series routers support Online Insertion and Removal (OIR) of fabric cards only when replacing a card with the same type and speed— for example, swapping 88xx-FC with 88xx-FC or 88xx-FC0 with 88xx-FC0. If it is necessary to replace a fabric card with a different type or speed (for example, from 88xx-FC to 88xx-FC0 or vice versa), the router must be powered down prior to the replacement. Mixing different types of fabric cards in an active system is not supported and may result in system functionality issues.

The router uses either a minimum of four or a maximum of eight fabric cards but you can replace a fabric card while others are operating. To replace a fabric card with the same type, you must do each of the following:

,

  • Shut down the fabric card being replaced.

  • Remove the fan tray covering the fabric card in the chassis.


    Note
    To ensure adequate airflow and prevent overheating, do not operate the router with three fan trays for more than 10 minutes.

  • Remove the fabric card.

  • Install the new fabric card.


    Note
    We recommend that you insert the fabric cards in the sequence starting with FC0, FC1, and so on (from left to right). Use the adjacent card as a guide to retain the cards in vertical position.

  • Reinstall the fan tray over the fabric card.

  • Activate the fabric card.

The Cisco 8800 series routers support OIR of fabric card.

To maintain the designed airflow while you remove the fan tray, the fans in the other fan trays increase their speed. During operations, it is required that you remove only one fan tray at a time and reinstall that fan tray within 10 minutes to avoid the possibility of having the router overheat and shut down. If you remove more than one fan tray at a time, the router shuts down if you do not reinstall the extra missing fan trays within two minutes (the shutdown can occur earlier if the router over heats).


Note
If the router is using only five fabric cards (5fc mode), the fabric cards must be inserted in FC slots 1, 2, 3, 4, and 5.

Note

Opening the ejector levers of an installed fabric card causes the fabric card to shut down even when the captive screws are screwed in. To reboot the fabric card, users must do one of the following:

  • Remove and reinsert the fabric card and close the ejector levers.

  • Close the ejector levers and reload the fabric card using the reload location <rack>/<fabric card location> force command.

Watch Replace a Fabric Card (Video).

Remove a Fabric Card

Before you begin

  • You must wear an electrostatic discharge (ESD) wrist strap or other ESD protective device while handling modules.

  • Prepare an antistatic surface or packing materials for each module that you remove from the chassis.

Procedure

Step 1

If you are replacing a fabric card, open the packaging for the new module and inspect it for damage.

If the module is damaged, alert the Technical Assistance Center (TAC) and stop this replacement process until you have an undamaged module to install.

Step 2

To prevent loss of packets during operations, shut down the fabric card as follows:

  1. Shut the fabric control plane using the controller fabric plane <plane-id> shutdown command.

    There are eight planes and the value of the <plane-id> is between 0–7.

    When you are replacing the card, shut down the corresponding fabric plane of the card. For example, when you are replacing the card in slot 0 (0/FC0), shut down fabric plane 0.

  2. Run the shutdown location 0/FC location command.

  3. Verify that the Fabric LED for the slot that you specified turns off. Also, you can use the show platform command to verify that the status of the card is SHUT DOWN.

Step 3

Remove the fan tray covering the fabric card in the chassis.

Refer the fan tray removal procedure:Replace a Fan Tray

Step 4

Remove the fabric card that you are replacing by following these steps:

  1. Unscrew the two captive screws on the center of each of the two handles on the fabric card (see Callout 1 in the following figure).

  2. Rotate the handles outwards until they stop (see Callout 2 in the following figure).

  3. With each of the two handles in your two hands, pull the module a couple of inches (about 5 cm) out of the slot (see the following figure).

  6. Rotate the module 90 degrees and lay it flat on an antistatic surface or in an antistatic bag.

Install a Fabric Card

Procedure

Step 1

Unscrew the two captive screws (one on each ejector handle) and rotate the ejector handles at least 30 degrees. Ensure that the locking posts on the top and bottom of the chassis rotate into the module so that the module can slide fully into the slot.

Step 2

Place one hand on the front of the module and turn the module 90 degrees so that the electrical connectors are on the bottom.

Step 3

Align the guide bar on the bottom of the fabric card into the guide slot at the bottom of the fabric card slot, and make sure that the guide rails on the top of the fabric card align with the track on the top of the slot.

Note

 
The lower guide rail extends to the back of the chassis. The upper guide rail does not connect until the card is halfway into the chassis.

Step 6

Tighten the captive screw on each of the two levers to 8 in-lb (0.9 N-m) of torque, so that each lever is locked in place on the module.

Step 7

Verify the fabric card LEDs become green.

Step 8

Reinstall the fan tray over the fabric card.

Refer the installing the fan tray procedure: Install Fan Tray

Step 9

Run the reload location 0/location/CPU0 command.

Step 10

Wait for the fabric card to become operational. Use the show platform | inc FC command to verify the status.

Note

 
The fabric card must be operational before resetting the fabric plane.

Step 11

Reset the fabric control plane using the no controller fabric plane <plane-id> shutdown command

Step 12

Verify that the Fabric LED for the slot that you specified turns on. Also, you can verify that the card is in power on state by running the show platform command to verify the status of the card to be POWERED_ON.

Since the Fan trays are blocking the view, Fabric card LEDs might not be visible. Therefore, you can verify the Fabric card LEDs status using show led location 0/FClocation command.

Replace Power Supply Components

The Cisco 8800 series routers support OIR of power modules. If you are replacing a redundant power module, you can replace the power module while the system remains powered on without any electrical hazard or damage to the system. This feature enables you to replace a power module while the system maintains all routing information and ensures session preservation.

However, to maintain operational redundancy and proper cooling, and to meet EMI compliance standards, you must have at least one working redundant power module that is installed. When you remove a failed power module with the router in operation, perform the replacement as quickly as possible. Make sure you have the replacement power module ready before beginning the removal and installation procedure.


Note
For the RP to communicate properly to a power module in a power tray, input power to at least one of the power modules in the power tray should be present.

This section contains procedures on how to replace the power modules.


Caution
Do not turn off the switch on the power tray to remove individual power modules. Power modules support OIR, so they can be removed and replaced with the power on and the system operating.
