Replacing the Fan Trays and Air Filter


Note
The LCC is shipped with the two fan trays and an air filter preinstalled.

Information About the Air Circulation Components

About the Fan Trays

The NCS 6008 LCC is equipped with two fan trays to provide the cooling required to protect critical components throughout the system from overheating. This arrangement is designed to ensure high availability in the cooling system. Typically, the fan trays share the cooling load, but each is capable of cooling chassis in normal operating conditions (up to 40°C [104°F] ambient room temperature) if the other is down. This is a diagram of the air circulation in the NCS 6008 LCC.

Temperature sensors mounted on the critical components throughout the system are monitored by the system software. Whenever a component breeches the preliminary threshold set for that component, a message is sent to the fan tray to increase fan speed until the temperature returns to normal. If the critical threshold is breeched, the card is shut down to avoid permanent damage.

Normally, all fans operate in unison to provide the appropriate air circulation in the chassis. When an adjustment needs to be made in the air flow, messages are sent to both fan trays to increase or decrease fan speed. If one fan tray fails or is removed, a message is sent to other fan tray to increase fan speed to the maximum. Should both fan trays be down at the same time on a running system, a general alarm is issued and a CLI warning message sent stating that the system will shut down in 45 seconds to avoid component damage in the system. Any fan tray that is down or removed should be replaced as soon as possible to ensure adequate redundant protection in the chassis.


Note
The upper and lower fan trays are interchangeable and installed in the same manner.

There are two fan tray models: NC6-FANTRAY and NC6-FANTRAY-2.

  • NC6-FANTRAY is supported in Cisco IOS XR release 5.0.0 and later. However, it does not support the enhanced air flow and monitoring capabilities introduced in Cisco IOS XR release 6.1.2.

    Figure 17. Fan Tray

  • The NC6-FANTRAY-2 is supported in Cisco IOS XR release XR 6.1.2 and later. Cisco IOS XR release 6.1.2 introduces enhanced air flow and monitoring capabilities.

    Figure 18. Fan Tray 2

Caution
Both fan trays installed in a chassis must be the same type. Do not install NC6-FANTRAY and NC6-FANTRAY-2 fan trays in the chassis.

Caution
If you install two NC6-FANTRAY-2 in a system that is running software earlier than Cisco IOS XR 6.1.2, the software does not recognize the fan tray and the system will shut down within 45 seconds.

A bicolor status LED is located on the front panel of the fan tray. The LED signals the operational status of the fan tray. This table describes how the LED colors are used.

Table 1. Fan Tray LED

State

Description

Green

About the Air Filter

The Cisco NCS 6008 LCC has a serviceable air filter mounted in a slide-out tray accessible from the front of the LCC just below the card cage (Figure 1). The air filter removes dust from the room air drawn into the LCC by the two fan trays. Once a month (or more often in dusty environments), you should examine the air filter. Replace it if it appears excessively dirty or damaged.

Failure to replace a compromised air filter can result in insufficient air circulation through the LCC and temperature-related environmental alarms. For information about replacing the air filter, see the Replacing the Air Filter.


Note
To comply with Telecordia GR-63-Core standard air filter requirements for NEBS deployments, the air filter must be replaced, not cleaned.

Replacing Air Circulation Components

Replacing the Fan Tray

Prerequisites

Before performing this task, open the cosmetic doors, if installed.

If you are installing Fan Tray 2 (NC6-FANTRAY-2), make sure the system is running Cisco IOS XR 6.1.2 or later.


Caution
Both fan trays installed in a chassis must be the same type. Do not install NC6-FANTRAY and NC6-FANTRAY-2 fan trays in the chassis.

Caution
If you install two NC6-FANTRAY-2 in a system that is running software earlier than Cisco IOS XR 6.1.2, the software will not recognize the fan tray and the system will shut down within 45 seconds.
Required Tools and Equipment

  • ESD-preventive wrist strap

  • 6-inch, number-1 Phillips screwdriver

  • Fan tray (NC6-FANTRAY-2 or NC6-FANTRAY)

Steps

To replace a fan tray, perform the following steps:

Procedure
Step 1

Attach the ESD-preventive wrist strap to your wrist and connect its leash to the ESD connection socket on the front side of the LCC Figure 1. You can also connect the ESD-preventive wrist strap leash to any bare metal surface on the LCC.

Step 2

Using the screwdriver, loosen the two captive screws on the fan tray faceplate. If necessary, use a step platform to reach the upper fan tray comfortably.

Step 3

Pull firmly on the fan tray handle to pull it free; two people are required to remove the fan tray.

Caution 
Because of the weight of the fan tray, approximately 30 lb (14 kg), two people are required to remove the fan tray. You should be especially careful while removing the fan tray from the LCC. To prevent injury, keep your back straight and lift with your legs, not your back. Avoid sudden twists or lateral moves. It is safer to use two people to remove the fan tray rather than a single person.
Step 4

Grasp the fan tray handle and pull it straight out to disconnect the fan tray from the connector mounted on the front of the fan tray bay on the rear side of the LCC. Slide the fan tray halfway from the fan tray bay.

Step 5

Use your free hands to support the fan tray, and then slide the fan tray completely from the fan tray bay.
Step 6

To install the replacement fan tray, use both hands to support and position the fan tray in front of the fan tray bay (label is on top).

Slide the fan tray into the fan tray bay. Stop when the fan tray makes contact with the LCC connector in the back of the fan tray bay.

Caution 
To prevent damage to the LCC connector, do not use excessive force when inserting a fan tray into its bay.
Step 8

Firmly push on the fan tray handle to seat the fan tray connector in the LCC connector. When completely seated, the fan tray faceplate flanges meet the rear side of the LCC.

Note 
All electrical and control line connections are made automatically when the connectors mate. The LED will light when the fan tray is inserted. The LED is yellow initially, until the system has confirmed it is functioning correctly.
Step 9

Tighten the two captive screws on the fan tray faceplate.

Replacing the Air Filter


Note
We recommend that you change the air filter every three months. The filter is sold in packs of 5 (Cisco PID NC6-5XFILTER=).

Note
A lattice of wire exists on both sides of the filter material with an arrow denoting airflow direction and a pair of sheet metal straps on the downstream side of the filter assembly.

Caution

Never operate the Cisco NCS 6008 LCC without an air filter. Operating the LCC without a filter for an extended time can result in damage to the chassis hardware.

Steps

To replace the air filter, follow these steps:

  3. Tighten the two captive screws on the front of the filter cover.

Removing the Route Processor Cards and Fabric Cards

This section describes how to remove the route processor (RP) cards and fabric cards (FCs) from the LCC.

Guidelines for Removing a Card

  • Online (in-service) insertion and removal (OIR) is supported, enabling you to remove the cards while the LCC is operating. OIR is seamless to users on the network, maintains all routing information, and ensures session preservation. It is not necessary to notify the software or reset the power. OIR removes power to a specific slot before the card is replaced. The power remains on for all other card slots.


Note
We recommend that you perform a graceful shutdown to shut down a card prior to removing it from the LCC. See the Steps for OIR Card Removal.

  • The different cards in the LCC are attached to the LCC itself using a pair of ejector levers and captive screws. The two ejector levers release the card from its backplane connector. The exact locations of the ejector levers and captive screws can vary slightly from card to card, but are generally in the same locations: on the upper and bottom ends of the faceplate.

  • When you remove an FC, you must press the OIR button before using the ejector levers to ensure that the connector pins disconnect from the backplane in the sequence expected by the LCC.

  • Any unused card slots that are uncovered allows air used for LCC cooling to escape. To ensure proper air flow and maintain system EMC and safety compliance, any unused FC slots must contain impedance carriers (see the Installing and Removing an Impedance Carrier and the Slot Numbers–Front and Rear Side).

Removing an RP Card

Prerequisites

Before performing this task, open the cosmetic doors, if installed. The RP cards are hot-swappable.

Perform these tasks when you are certain that the other RP card in the chassis is operational and, if not already the Active RP, is ready to assume control (this happens automatically). Failure to follow these guidelines can result in interruptions in data communications and network connectivity.


Warning
