Safety Guidelines

Before you begin the replacement procedure, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.

In addition, before installing, configuring, or maintaining the Cisco 12404 Internet Router, review the safety warnings listed in the document Regulatory Compliance and Safety Information for the Cisco 12000 Gigabit Switch Router Series (Document Number 78-4347-09) that accompanied your router.

Safety Warnings

Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement. The following paragraph is an example of a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard. The remaining paragraphs in this section are translations of the initial safety warning.

Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. (To see translations of the warnings that appear in this publication, refer to the appendix "Translated Safety Warnings" in the installation guide that accompanied this device.)

Waarschuwing

Dit waarschuwingssymbool betekent gevaar. U verkeert in een situatie die lichamelijk letsel kan veroorzaken. Voordat u aan enige apparatuur gaat werken, dient u zich bewust te zijn van de bij elektrische schakelingen betrokken risico's en dient u op de hoogte te zijn van standaard maatregelen om ongelukken te voorkomen. (Voor vertalingen van de waarschuwingen die in deze publicatie verschijnen, kunt u het aanhangsel "Translated Safety Warnings" (Vertalingen van veiligheidsvoorschriften) in de installatiegids die bij dit toestel is ingesloten, raadplegen.

Safety with Equipment

The following guidelines will help ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert.

Always disconnect all power cords and interface cables before moving the system.

Never assume that power is disconnected from a circuit; always check.

Keep tools and assembly components away from walk areas.

Do not work alone if potentially hazardous conditions exist.

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Safety with Electricity

Follow these basic guidelines when working with any electrical equipment:

Before beginning any procedures requiring access to the interior of the router, locate the emergency power-off switch for the room in which you are working.

Disconnect all power and external cables before installing or removing a router.

Never assume that power has been disconnected from a circuit; always check.

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Never install equipment that appears damaged.

Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident does occur, proceed as follows:

Use caution; do not become a victim yourself. Disconnect power to the router.

If possible, send another person to get medical aid; otherwise, assess the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

In addition, observe the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone or network wiring:

Never install telephone wiring during a lightning storm.

Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage to circuit boards can occur if they are handled improperly. Such mishandling can result in intermittent or complete failures of the board.

When handling circuit boards, observe the following guidelines to prevent ESD damage.

Always use an ESD-preventive ankle or wrist strap and ensure that the strap makes adequate contact with your skin.

Attach an ESD-preventive strap to your wrist or ankle and to the chassis; or to a bare metal surface. See Figure 1.

The ankle or wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing can still cause damage to electronic components.

Figure 1 Attach ESD-Preventive Strap to Cisco 12404 Internet Router Chassis


Caution Periodically check the resistance value of the antistatic ankle or wrist strap. The resistance measurement should be between 1 and 10 megohms.

Cleaning and Replacing the Air Filter

The Cisco 12404 Internet Router has a serviceable, hot-swappable air filter. Facing the rear of the chassis, the air filter is housed on the left side of the chassis. The air filter location is shown in Figure 2. Air flow through the air filter is shown in Figure 3.

The air filter removes dust from the room air drawn into the router by the cooling fans. Once a month (or more often industy environments), you should examine the air filter. If the filter appears dirty, you can either vacuum or replace it. If the filter appears worn or torn, dispose of it in a responsible manner and install a replacement air filter.

Cleaning and replacing the air filter is presented in the following sections:

Tools and Equipment

Remove the Air Filter

Install the Air Filter


Note You can perform these procedures with the router power On.


Tools and Equipment

You will need these tools and equipment to change an air filter:

ESD-preventive strap and leash

Vacuum cleaner

Replacement air filter, Part Number: ACS-GSR04-FLTR=

Remove the Air Filter

The procedure to remove and clean an air filter is presented in the following steps.


Note Do not damage the air filter. Damage to the air filter can restrict the airflow and cause an overtemperature condition in the router.


Figure 2 Cisco 12404 Internet Router Air Filter Location


Step 1 Attach an ESD-preventive strap to your wrist or ankle; and attach the ESD clip to the chassis or to a bare metal surface.

Step 2 Grasp the small tab on the edge of the air filter and pull the tab to remove the air filter from the housing.


Tip If you are unable to lift the tab on the edge of the air filter, use a 3/16-inch flat-blade screwdriver to lift the tab, then grasp it.


Step 3 Pull the air filter out of the chassis housing.

Figure 3 Cisco 12404 Internet Router Air Filter Direction of Air Flow

Step 4 Visually check the condition of the air filter.


Caution When cleaning or replacing the air filter keep it away from the RP and line card cage so that any dislodged dust will not be drawn into the cage. Do not vacuum the air filter while it is installed in the housing.

If the filter appears dirty, you can either vacuum or replace it.

If the filter appears worn or torn, dispose of it in a responsible manner and install a replacement air filter.


Caution Never wash an air filter and immediately reinstall it in the chassis, because moisture drawn inside the chassis can damage the components. Allow the air filter to become completely dry.


Install the Air Filter

Instructions for installing the air filter in the air filter housing, at the left rear side of the chassis, are presented in the following steps. Use Figure 2 as a reference for installing the air filter.


Step 1 Attach an ESD-preventive strap to your wrist or ankle; and attach the ESD clip to the chassis or to a bare metal surface.


Timesaver The arrows on the top edge of the air filter note the direction of air flow. Insert the air filter into its housing with the arrows pointing toward the card cage.


Step 2 Slide the air filter completely into the air filter housing.


Caution Do not damage the air filter. Damage to the air filter can restrict the airflow, cause an overtemperature condition in the router and degrade EMI performance.
